Height Loss

Whilst celebrities have access to everything money can buy, unfortunately, like us mere mortals, they can succumb to the rigours of aging, including height loss.

Studies have been done in the past on typical loss of height but results I've seen vary. A recent study revealed the following: "To determine the magnitude of height loss that accompanies aging, longitudinal studies are required. The authors studied 2,084 men and women aged 17-94 years enrolled from 1958 to 1993 in the Baltimore Longitudinal Study of Aging, Baltimore, Maryland. On average, men's height was measured nine times during 15 years and women's height five times during 9 years. The rate of decrease in height was greater for women than for men. For both sexes, height loss began at about age 30 years and accelerated with increasing age. Cumulative height loss from age 30 to 70 years averaged about 3 cm (1.18 inches) for men and 5 cm (1.97 inch) for women; by age 80 years, it increased to 5 cm for men (1.97 inch) and 8 cm (3.15 inches) for women"

Another study which covered a 20-year period of nearly 8000 men showed men lost on average 0.66 inches (1.67cm), with samples in the initial age range being 40-59 and final height 20 years later taken when they are 60-79.

Sometimes the results of shrinking can be drastic, other times celebrities barely shrink at all. The reasons for loss of height can range from bad posture (hunching), osteoperosis resulting in fractures, surgeries like knee and hip replacements, curvature of the spine. Some noticeable cases of stars shrinking are Ann Miller (5ft 7 to 5ft 3), Clint Eastwood (6ft 4 to 6ft 1), Hulk Hogan (6ft 6 to 6ft 4), James Garner (6ft 2.5 to under 6ft), Charlton Heston (6ft 3 to under 6ft). I will usually give a peak/current height for celebrities who are still in the public eye. If they've retired from acting and are out of the spotlight, I will just leave at their peak height.

Rob, if you worked construction as your career (and didn't have any accidents) do you think you would have held on to your heights when your 20 at say 38?
[Editor Rob: I think by 40 if you had a 20 year career in a real physical job, you might lose 3-4mm by then through natural wear and tear.]
Blake said on 8/Oct/17
Rob, I to my surprise for the last couple of weeks have measured roughly 5 ft 9.5 on average out of bed after 7 hours out of bed. Would it be fair to say I was 5 ft 8.75 now?
[Editor Rob: it's probably safe to go with that as your height now.]

@Jason I really can’t explain why. Hopefully it doesn’t get worse!
Jason (192.5) said on 4/Oct/17
Hi Rob, is 2.5cm of height loss extreme for someone of my height? (194.5cm morning 192cm lowest).
[Editor Rob: yes it's quite a normal and expected shrinkage for a few inches over 6ft.]
Jason (192.5) said on 4/Oct/17
@Hunch that is pretty crazy actually. I go to bed at your height (192cm) but wake up at 194.5cm. I thought that was a lot of height loss!
Richard said on 3/Oct/17
Rob forgive me for my ignorance, but when you say " static" Does that mean contraversial?
What is your own opinion ? I personally dont believe they do or could -at least not vert noticable at all. On that note I dont believe a persond height defines them as a human being. I mean, it doesnt measure integrity ,honesty or compassion in a human being. But once again thanh you for your reply. I am just curious as to your own opinion on that.Just never heard anyone mention that.

[Editor Rob: I just mean it is more stable, it won't change as much as our spine, because our arms don't have discs...some bone loss could occur which means the armspan reduces, but compared to our height, it will be minimal.]

Hi Rob, I have a question for you. is measuring one's height with a book on a tiled floor of a bathroom is rather accurate?. This is because I've made measurements of my height on different surfaces and I've consistently gotten values in the range 178.2-177.7 for my lowest height, yet I don't know which one is my low, because the values obtained on the tiled floor are at the higher end (178.2) while the other values on the other surfaces were varying within the range. I know the difference between the highest and the lowest value is just 5 mm, a negligible value, still I'd like to know your opinion on this.
[Editor Rob: some floors might look level, but there could still be a slight slope, which accounts for a little fraction of a difference in measurements. Sometimes taking the average from different rooms is the best figure to go with.

Using a book is ok, I would personally find a book that had a hard cover and use the spine as the part that measures the top of our heads.]
Richard said on 2/Oct/17
Rob do your arm lenghth shrink also as a person shrinks? Interesred to know this. Ive never heard anumyone say this.??
Thanks.
[Editor Rob: it's pretty static]
Hunch said on 30/Sep/17
I have been tracking my height carefully for a bit now to double check. I’m 6’5” (196 cm) out of bed and my typical low at about 10:00 or 11:00 PM is 6’3.5” (192 cm). However, some days when I am really struggling with my back, I can have an extreme low of 6’2” (187-188 cm) even at 2:00 PM. Is this something that any other individual is known to have? I do have scoliosis and the height loss is noticeably from being physically unable to stand straight even when I try very hard to do so. Also, I go from 6’5” to 6’4” within the first hour of waking. 6’3.5” to 6’4” for most of the day.
9gagger said on 28/Sep/17
Hey rob is it common for people under 6 feet to lose 3cm through the day
I go from 177-174
174 under extreme cases,typically 174.5 is my lowest
[Editor Rob: it's greater than average, but some folk do shrink a full 3cm]
Richard said on 21/Sep/17
Rob,haf to see if you tesponded. As to your reply- neither have I. But this happened. I dont have a valid explanation. But from what I understand the bone decay is necessary for your body to produce the new cells. Also one last interesting note. Imaging of my back and neck were horrible Some yrs ago. I also had 3 tears between my discs in my lower back and in my neck. I hurt my back when I was 19 very badly at work. As for my neck I have know idea what or how that happened. I woke up that way with my neck huting in 2006. Doc told me sometimes that can happen. But I dont know. Maybe the rips or " tares" in my back and neck healed and thats how? Im just ad freaked at this as anyone. But I keep remembering every time science tries to say this is the definitive rule or law( in example : the worlds flat- man cant fly ,etc...- try explaining a t.v. set to a mdieval knight!) Science has been wrong. I mean in a100, a 1000 yrs from now well probably know stuff that right now in 2017 we cant even begin to concieve. Anyway, its happened and Im no closer to understanding as you are. Thanks for replying.
Ricardo said on 20/Sep/17
Hello Rob, I am thinking about buying a portable Stadiometer, which one would you recommend me? one having a very small error! Thanks!
[Editor Rob: depending on country, I would just look at medical supply companies as usually those will be best price. Seca are still one of the better ones and the portable version is only 1/8th inch off (the one I have). Their latest models I don't know, I haven't checked accuracy yet!]
Richard said on 20/Sep/17
Rob Im not kidding,joking or definitely not lying as I think your response indicates tat. I have contacted 2 medical proffesionals who know me and they believe me. They said that this might not be good though. The closest ive come to seeing anything remote was that a brain tumor can cause this. But only in people that are still growing. However I did find a research site that said theres some evidence that if a person has bone decay and something about calcification and that you body still releases hgh ( just in much smaller amounts as you age) and you do also produce stem cells that there was evidence that(( I didnt quite understand all of it) but that bone growth could occur- not at the ends- but rather from between the plates. Look Rob Im no doctor and I knew no one would believe this. But I have to take a pig enzyme to replace the enzyme in my pancreas and I have a over reactive thyroid- hypo. I definitely have bone atrophy also. I startef taking a hgh supplement by the way about 4 months before this happened because I read it could help your joints. I dont know what happened honestly and my wife thought she was shrinking! I dont have a valid explanation for this and I have a funny feeling I wont be around much longer. But I dont expect you to believe me but I cant wrap my head around this either. I do know I am not making this up and quite frankly it scares me. But before you just start assuming people are dishonest why dont you have some" miracle growth" in your soul and start by not trying to amuse youself and your readers at someones expence. I dont blame you for not believing this as it doesnt fit anything that we ,or as we know it. But as I said ,this is crazy and I dont know what to think of it. I dont have any smiley faces on this phone but If I did I would send you back a sad one. With that Rob ill sign out and not come back to this site. You can just chalk it up to " some crazy guy" and ill go back to worrying. Ive been hesitant about going to the National Institutes of Health her in Maryland. Im not a big fan of people probing and inspecting me and saying. are you sure you werent ever that tall already? Man, I dont know. Maybe one day well know or rather science will. Have a good and " normal" life. Mine certaintly became strange. But if you care to , google height increase as an adult research and you might find what I read.
Richard
[Editor Rob: it certainly would be an interesting research study for medical professionals. I do know there are some people who suffer from late closure of growth plates, and so have still gained height in late 20's, but age 50 I've never heard of before.

Rob when I was 18 years old and I was 185.5 cm and now I'm 22 years old I measured 184.5 cm I can not find a logical explanation of this, I think it was because in those 4 years I had a great depression and the only thing I did at that time was playing videogames all over day and eat pass from weighing 80kg to 125kg which is what weight nowadays the combination of all those factors will have reduced my height?
[Editor Rob: sometimes you need the exact same setup (room/floor/tape/method) to see if height loss occurs, because 1cm isn't huge, even the time of day can effect it.]
Richard said on 17/Sep/17
Every time I write something it never ends up on here . Do you think im a different person? I just wrote again the other day of an incredible event- at 52 yrs old I jus grew 2.5 inches. This isnt one of those nut claims! Ther could be a significant medical reason for this. By the way, i just started looking at this site when I noticed John Waynes height on here. Youtube vids of him at home etc....he was exactly as he his wife and his secretary claimed. Its funny, people will downgrade everyone else to try and achieve his or what they think someones height is. Thats crazy. Better yet warch his olfer movies. I usef to have movie books that had many pics of the making of movies. For instance when a close up came of randolf scott standing eye to eye in the spoilers, scott wore boots and wayne was in his socks. Thers another scene out on the board walk where they stand eye to eye then wayne walks off. Then you can actually see where they stop the camera and start it again with just scott standing there so he can walk off. There is a sign behind them and you can clearly see the difference in scotts height so he can the walk off. Yeah they did all kinds of little things like that back in the fay. See Greg Palmers bio. He talks about how big he is and how hollywood wantef the heros adversary as big as the heroes for " the showdown" he was called for wayne 5 times and appeated as james arnesses adversary 21 times on gun smoke. Just thought youd be interested to know. But This crazy height increasr Ive had worries me as my health overall isnt great. You can contact me if youd like at. rindycedmond@hotmail.com
[Editor Rob: your epiphyseal plates reopened after lying dormant for 30 years and now at 51-2 they started producing more bone...certainly sounds like a height miracle 😁]
Blake said on 12/Sep/17
Rob, I don't quite understand the difference between a low and extreme low I had a more average day today and I measured over 5 ft 8 3/4 at the end of the day yet the couple of days before I had been feeling sick and barely any sleep and being still for nearly the entire day (im talking a couple of hours for 2 days, food etc and measured 174.2 so what is my low? Is it in between the measurements or is it the height I measured when I was up for basically 2 days?
[Editor Rob: I think if you take a measurement at 7-8pm (after being standing or active for several hours in afternoon) and do it several times over a week, just take the average as your typical low.]
Blake said on 11/Sep/17
Rob, is humans height growth done completely while asleep? I have a theory that more youngsters might grow during summer as firstly they do more exercise on average and in my case from spring to summer I got more than double the sleep I got during the winter
[Editor Rob: yes, when asleep the body repairs and grows during it, which is why exercise (to promote growth hormone production), variety of food (to give our body the right nutrients) and the actual sleep are all important as teens.

Staying up till midnight playing Doom or mario or whatever could have a little impact on our potential growth.]
MrCaesar said on 10/Sep/17
Hi Rob. At what age on average a man start losing height? Can a man reach 55 without losing anything? And if not, how much height can by lost at 55?
[Editor Rob: 50-55 is for many men, a period in which a little fraction is lost, but I feel the 60-65 range is when a majority of men do experience a more noticeable loss.]
Punisher94 said on 4/Sep/17
Hi there, Rob. Great work with the site. I was wondering how long do you think morning height lasts. I have observed myself. Usually after 2 hours I loose a fraction maybe 0,7 cm or a full cm, and then for the rest of the day depending on what I do I can loose another centimetre and a half resulting in a 2,5 centimetre shrink from my morning height to my evening height. Also last year I had mild Anterior pelvic tilt (Lordosis) and by doing exercises and being mindfull of my posture I increased my height by 3-4 centimetres. Do you think that young people can loose height due to posture and then regain it by discipline and sheer will?
[Editor Rob: I believe some people have regained lost height through exercise/posture correction.

The drop off in height in first 3 hours is quite a lot, a good chunk of our daily height lost occurs in those first few hours.]
Jo said on 2/Sep/17
I begin the day at 183 and in the evening I shrink to 181.
Till 4 pm I am 182. Claiming 182 is not wrong isn't it?
[Editor Rob: it's not unreasonable, especially since you can still be near 182 at late afternoon.]
Rubik said on 28/Aug/17
Hi Rob, can the yoga to prevent height loss as well as your height workout?
[Editor Rob: you can take the simple ideas in the height workout and add in knee raises, scissor moves and a few others to work various muscles and keep spine in shape.

Yoga, varied diet with enough minerals as we get older, keeping active by simply getting out there and walking (instead of taking car) all can help.]
Yes said on 23/Aug/17
Rob, does squats decrease your height, and does they make you reach your lowest?
[Editor Rob: there's a lot of strain on discs so they might push you to an absolute low (if measuring after a heavy squat session).

Long term (many years) they could increase chance of disc damage.]
Mimi said on 22/Aug/17
Is it normal for my dad to lose almost an inch of height at 64?
[Editor Rob: about 0.5-0.75 is very normal, 1 inch maybe a little bit above average by that age, but not uncommon. By age 70 1-1.25 inches is a common loss for men. ]
John Davis said on 17/Aug/17
Rob can you retain morning height by hanging from a bar?
[Editor Rob: not really, lying down at regular intervals during the day would help, but it's a bit impractical!]
Criss said on 30/Jul/17
Hi Rob,
I have a dilemma. In the morning a have 184, by the evening I drop to min 182. Is this a 6 footer range?
[Editor Rob: for a good chunk of the day you will be six foot, only maybe last 5-6 hours you are a fraction or so under it.

Many with your morning/night will just say about six foot. Imagine you visited your Doctor at 11am and he said 182.8cm...you would certainly be saying six foot to people.]
Rising - 174 cm said on 26/Jul/17
I don't stretch unfortunately, which is quite inexcusable. I'm quite naturally athletic, but painfully inflexible. My knees have been arthritic for some time for a variety of reasons, basketball being one of them. That's caused me to drop posture at times and I noticed it affecting my lower back, but I at least do a lot of crunches and sit ups, which does seem to help and I have to start doing dead squats again to strengthen my knees.
Ricardo said on 26/Jul/17
Hey Rob, I have a question for you. And thanks in advance. There was a time, like 1 month ago, during which I measured my height with a hard-cover book everyday after getting out of bed and consistently got 179.7-180.2. Today, however, I measured myself again I got 179 on the dot, did I shrink? or simply am I dehydrated so I am not reaching my top morning height? I started drinking a lot of water again in case the reason is me being dehydrated anyways.
[Editor Rob: time of day may play some role in small differences, especially if doing active work or slightly less hydrated.]
Rising - 174 cm said on 25/Jul/17
That's true, Rob. Outside of genetics, I believe maintaining good posture and staying fit and active has a lot to do with not losing much. You look at someone like Sly who has better posture and in better shape than most half his age and it makes sense he'd be someone who made it to 70 while only losing perhaps 1 cm. Similarly, a guy like Charles Bronson still stood perfectly erect and appeared fit and it wasn't clear he had lost anything by age 70. Chuck Norris is another example. Clearly an active guy with a healthy lifestyle and he didn't seem to lose anything noticeable by early 70s and even now at 77, seems to have lost 2 cm max. But then there's someone like Kurt Russell who isn't in quite the shape of the others mentioned anymore, but has rarely seemed to slouch, which may be why he doesn't seem to have lost much at 66. On the otherhand, someone like Carl Weathers seems near his peak height even at 69, but looks youthful for his age, which may be an indication of good genetics as William Shatner also looks younger than his actual age of 86 and seems to have lost less than you'd expect by that age.

But whatever the reasons in each case, it's quite obvious height loss varies greatly among individuals.
[Editor Rob: when young, I think it pays to get into a habit...even 2-3 minutes a day doing toe stretch and ceiling stretch might help.
I do think if you spend a lot of time in an office chair, it might be worth buying a chin-up bar, and doing 1-2 minutes a couple of times a day hanging to alleviate and decompress your spine.]
Jenny said on 23/Jul/17
Hey Rob, I saw your picture with Anneke Wills from Doctor Who, who you list as 5'6 and it got me wondering, did she lose any height at all? She still looks 5'6 in that picture at 70. If she didn't then she's really lucky.
[Editor Rob: I'm in converse that day and she had a shoe that was thicker by roughly 0.75 inches, so she may not have lost more than 2cm...of course she could seem over 5ft 6 at times in Doctor Who...actually Michael Craze made this claim once:

"I'm 5 foot 7 and Anneke Wills is 5 foot 10"

In heels maybe...]
Rising - 174 cm said on 23/Jul/17
Here's an important note on height loss. It mentions the Baltimore Longitudinal Study of Aging survey Rob cites above, but emphasizes an important detail

"But averages hide wide variability: Some people lose an inch or more in a single decade, some shrink only after age 60 or 70, and a few don’t shrink at all."

Click Here

There are numerous examples of this. Not only did I notice some maintain their peak height to a pretty advanced age while others lose noticeable height while still young, but I've also noticed people can lose a lot of height at once and then maintain that height for years.
[Editor Rob: yes, some people have good genetics, but also they look after their bodies, ensuring adequate amounts of the right vitamins and minerals, in combination with exercise.

The sedentary lifestyle that many sadly adopt over 50 I believe contributes largely to some losses.]
Mahad95 said on 22/Jul/17
Hello rob my name is Mahad......I measured my self 4 times in gym once twice I was measured 176cm and twice I was measured 175cm but it wasn't any measuring error for sure. But yeah the thing is when I was measured 175 twice I didn't eat or drink anything that morning........if you don't take any glucose in the morning and check height do you shrink??
[Editor Rob: it's possible you were dehydrated a little and so your discs weren't as thick as if properly hydrated.]
Tyson said on 17/Jul/17
Big G maybe will loss 3 inches and should claimed maybe 5'4-5'5.
Colin said on 16/Jul/17
Hey Eob, I have a strange question about my friend. He was 17 years old when I saw him last time and he was about 6'2 in that time because we were in basketball team and I was in the same room in high school when they measured our heights. He is now 24 years old and I haven't seen him in last 7 years almost and he is about 6'4.50-60(1.94cm). Is this really possible according to science-way? From 6'2 to 6'4 after 17? I am 6'2 and he was really taller than me like 2 inches min.
[Editor Rob: yes, it is quite possible, he just had more than average growth after 17...]
Ricardo said on 15/Jul/17
Hey Rob, I have a question to you regarding losing height during summer. Given on a summer day, a person is prone to sweat more often, Is it likely to lose height (from out of bed height to normal low) more quickly throughout the day on a summer day?
[Editor Rob: it's always possible, but we are talking very small fraction.]
Nate said on 11/Jul/17
Rob, perhaps you can help me with this question, I am a 25 year old male.

I've woken up first thing in the morning at 184.7 cm tops and after a bad bad TERRIBLE day i measure myself at 182.0 cm and nothing less. I have over 1 inch of maximum shrinkage throughout the day. On average, i wake up at 184.5 cm and shrink to 182.3. Is this a normal shrinkage? Will i shrink less in the future. What's your take on this?

Thanks Rob.
[Editor Rob: with age, the morning to evening shrinkage will reduce as the discs won't be as thick or retain as much water as they did at age 20...

your shrinkage is within normal range. On a bad day you drop to 182 flat, but I'm sure on some days you might even be 182.5cm.]
Bob said on 27/Jun/17
I was 5'9.5" at my peak. I am now 50 years old and have been lifting heavy (squating/deadlifting) since age 15. I now measure just under 5'8". this is a bit disconcerting. I stretch every morning and even use an inversion table for 1-2 minutes every morning. I have not regained any height and continue to shrink. Is this normal for a former competitive bodybuilder/powerlifter who is otherwise very healthy? I continue to train heavy 4 days a week.
Marcus said on 16/Jun/17
Hey dude! I really liked your website
Andy said on 16/Jun/17
quick question Rob. When measuring, I realized my head is shaped so that it kind of protrudes at the back of it. So if I slightly tilt my head down, I tend to measure a little taller than usual. Is this considered a wrong way to measure?
[Editor Rob: I believe we should hold our heads level and look straight ahead for the measurement.]
Jason said on 14/Jun/17
Hey rob would you say that developing bad posture could cause you to lose a little height PERMANANTLY in your early 20s? I am 21 this year and I started developing pretty bad posture when I was about 18. I have noticed that I have shrunk about 0.5cm (almost 1/4 inch) since then. Granted that my routine has stayed relatively the same (going to college) and both measurements were taken by me in the morning at the same wall. Is this possible? I am talking about a permanent loss solely from bad posture and is there any way I can recover that loss?
[Editor Rob: you could try to regain/correct posture...there are many exercises on posture improvement on youtube, my own tip is the 5-minute height workout which helps me after 8 hours stuck on a computer chair!]
Slothee said on 13/Jun/17
Hi Rob, I've a question.

I saw my uncle who's turning 65 soon and claims he's currently 6'1.5" and that he's been this height forever. But at 64, I find it hard to believe he hasn't really lost any height. His kids have told me he's 6'2" btw.

Do you think his peak height was at least 6'2", or is it possible he hasn't lost anything at his age?
[Editor Rob: a small percentage will make it to mid 60's without any noticeable loss...though he may still have lost a small fraction, which isn't noticeable.

I'd be delighted to hit 65 with only 1/3rd or 1/2 inch lost!]
Im 171CM said on 13/Jun/17
Got to stretch your spine to have your full height potential in my opinion...
Ricardo said on 6/Jun/17
I am a 5'10 guy (out of bed height 179.9-180.1), though I've noticed I reached a morning peak height when I did stretching exercises the night before. These last weeks I've been "studying" my height to know its changes throughout the day, and I've noticed that I loss height quickly as soon as I go out and about, reaching my low 178 quickly. Does losing height quickly has to do with excess of weight, my weight is about 110 Kg, which is certainly too much for my height?
Tim said on 24/May/17
Hey Rob the doctor measured my morning height to be a little over 6 ft 1. What height should I claim if I lose 1/2-3/4 of an inch throughout the day?
Blake said on 23/May/17
Rob, would you say that if I slept 8 hours on my back because I sleep on to the side I would reach over 5 ft 9 because the highest morning height I got was bang on 5 ft 9
[Editor Rob: 1 pillow, on back might get you a solid 5ft 9...but, it can be notoriously hard to sleep the same way, you toss and turn a lot!]
GeminiCastor said on 17/May/17
Hi Rob.
how much does a 57 old man, who is sedentary and work a lot with pc, has lost according to you? Consider that that man isn't active at all. if that can help, this man does not have grey hair and look at least five year younger.
and another question, when did he start to loss height? by 50?
thanks
[Editor Rob: I'd expect at least half inch and more like 3/4 inch by that age...if he is fitter and does regular exercise, good diet, then he might still reach 57 with only say 1/4 inch lost.]
Blake said on 14/May/17
Rob, is this an average shrinkage I measure 1/16th of an inch under 5 ft 9 a few minutes out of bed and at my low I measure a milimetre over 5 ft 8.25
[Editor Rob: it's a very typical shrinkage yes. Close to 0.7 inch...]
Unknown said on 12/May/17
How much can lose a man of 5'5" at age 50-60-70-80 at the maximum and at the minimum?
[Editor Rob: you are very lucky if you reach 70 and only lose say 1/4 inch...it is more common to lose closer to 1 inch by then.

Typically a fraction by 50, maybe closer to half inch by 60, 1 inch by 70, 2 inch by 80.]

I am 22 years old, I measure 1.74, do you believe that exercising and eating well can achieve a few centimeters?
Scott said on 22/Apr/17
LOL! Meant to say 179.5 cm
Scott said on 13/Apr/17
@ Lawrence: Under normal circumstances, you shouldn't lose height at 30. However, It isn't unheard of. I am 31 and I lost a bit off my normal height.I would wake up at 6' out of bed and go to bed at 5'11.25'' or 5'11'' flat at worst.A couple of years ago, I noticed I was around 5'10.5''or 5'10.625'' in the evening. I thought I made a mistake at first, and I had a nurse measure me and sure enough the rod read 179 cm.
Scott said on 11/Apr/17
My late grandfather used to be about 6'2'' in his youth. In December of 1972, he had a motorcycle wreck and broke nearly every bone in his body. It took two years for him to recover, but he lost height afterwards. His final height, before he passed, was close to 5'9''.
sumdude said on 10/Apr/17
I measured myself for a new passport at the police-station this year(morning height). We have to do it every 5 years where I live. They measure you with a stadiometer just like the Rob uses.
I visit the doctors office often(morning height), I was hoping my measurement at the doctors was wrong, but no. Same result as the measurement at the police station. So, I have lost ~1.1-1.6cm in height compared to myself 5 years ago at the age of 24. I'm 29 now. I have bad posture and have done a few extreme sports, so I guess that's a couple of causes as to why my height is gone. Diet and health is fine otherwise though.
Funny little story, my father was 197cm (morning height) in 1999. At the age of 59, now, he is 191-193cm(morning), depending on hours of sleep. Mechanic on heavy trucks for 41 years. Taken it's toll on his back for sure.
[Editor Rob: much rarer to lose height in 20's, but it can happen through overworking the body or injuries, developing bad posture too might effect it slightly.]

I live much, too much to home and I pass several weeks 3-4, without go out from house for studying.Also if I have only 25 years old, I have fear that I have a lack of vitamin D, because I don't sunbathe. Since several years (5-6) I sunbathe not much,except in summer where I sunbathe enough on the beach. Could I shrink my height, in this time? I drink a cup of milk everymorning. I am worried. Dear Rob, Is it possible shrink at 25-30 years old, for a lack of vitamin D for few sun?
[Editor Rob: Even on overcast days there is still sun rays, of course it's less intense.
I doubt you have shrunk...some foods have vitamin d, some cereals also have it included.]

Dear Rob, I'd be very grateful for some advice: am only 18; recently broke my foot, now out of cast. The leg which was in the cast is slightly longer than the other leg, and I am 1 cm shorter. Is this most likely a result of bad posture??
[Editor Rob: TK, your legs may simply be 1cm difference. If it is only a few mm that is nothing to be concerned about, but if 1cm, maybe a small dr scholl orthopaedic insert you wear in one shoe to balance your discrepancy is worth looking at.]
Judd said on 31/Mar/17
[Editor Rob: yes very reasonable, if I was 75 and only lost 2cm I wouldn't be unhappy!]

Rob in your opinion it's possible to guess a peak height of an aged person comparing to pictures (one of him/her young and one of him(her aged)and keeping attention to his/her proportions?
For example if i take a picture of a person took when he/she was young and i check that his/her head was 1/7 of the body then i can check how is the proportions head/body currently...it's a reliable method in your opinion?
[Editor Rob: it is much harder to guage height on a single photo than it is with references. A 5ft 8 man who was slim, small head could be photographed so he might look tall, and a 6ft man quite bulky with loose clothing may appear 5ft 7!

Knowing how much someone has shrunk is also another difficult task. it is easier to see in person I think, sometimes you can see the curvature in their upper back which can help.]

Hello Rob, do man start to lose height by age of 30? I am 25 years old and I am 6'2.75. Will I lose ant height when I will be 30 years old or 35 , 40 years old?

Or height loss is mostly starts at 50 for man?

Note: I am not lifting heavy weight or bodybuilding. I am sprinting,swimming,playing basketball and exercise my body mostly and having Calcium, D, C vitamins Normally.
[Editor Rob: at 30 it is highly unlikely to lose height. By 40 maybe some have lost a little bit, but at 50 there are more men who lose height. At 60 you are very lucky if you only lose 2-3mm.

Yes, keep eating good diet, the odd vitamin supplement may be fine, but you can get most of what you need from varied diet.]

Clint Eastwood was NEVER 6 FEET4 ! At most 6 1 . maybe with boots and his hair he was six four. That claim is rediculous. I met him once and I'm 6 feet. He was about a half inch taller than me. Hollywood is something!

Rob 2cms loss at half-70s from peak is reasonable?

Blake said on 25/Mar/17
Rob, do you have potential on a rough day to be under 173cm what sorts of activities could do this?
[Editor Rob: on an extreme day I might go to 172.8-9, but not been under really extreme conditions to test. I mean being dehydrated has potential to knock a couple of mm from anybody!]
Martha said on 24/Mar/17
I have a friend who says her grandmother loss 12" in height. She was 6' and less 5' when she died. Is this remotely possible? I mean no one mentioned anything about her having legs amputated, which might explain it.
[Editor Rob: there are some medical conditions which can cause extreme spinal curvature/degeneration, and the person might lose a foot, but it is much rarer.]

I wake up exactly 5'10 and shrink down to 5'9 3/8 by nighttime. Sometimes 5'9.25. Can I claim 5'10?
[Editor Rob: if you told people 5ft 10 'first thing' that isn't unreasonable, at least they'd know you might shrink to closer to 5ft 9 at night.]
CastorGemini said on 20/Mar/17
Hi Rob. Out of bed i'm 176,5 and before bed i'm 174,4.. what can I claim according to you?

Out of bed: 180,5
Most of the day: 179,4
Before bed: 179,1
Extreme low may be few mm below 179.
What height should i claim?
[Editor Rob: I'd just go with 179 5ft 10.5]

Canson said on 3/Mar/17
@Christian: your legs aren't excessively long for your height that's about average. I'm a 35-36 and am almost a full inch shorter wake up 195.8 (6'5.08) and go to bed at 193.9 (6'4.33). I only usually lose 3/4" most days whereas others if I go to the gym I can come down to 193.7 or even 193.2 if on my feet late night. You likely if you were to go out at night could get down as low as flat 6'5" if you are already losing 7/8" as is. Which is why I was wondering why you claim 6'6" (I personally wouldn't if that were me would just say 6'5" as the befits are not in it to be that tall really).
Yes yes said on 1/Mar/17
Hey Rob!

My uncle turns 65 in June this year and on his passport 2005 isch, I think, it says he's measured at 189 cm. So let's go with that his peak height 189 even tho he always says he's 190 lol which he can appear a lot of times.


How tall do you think he's now?
He doesn't have the best posture in the world but still pretty decent. Sometimes he can appear as low as 6'1" but other times he can appear HUGE and can look to be over 6'3" these days. I remember the summer of 2016 when we were exiting the market and in Sweden all stores have tapes on the wall right beside the exit where it says how tall you are and watched my dad walk past, his shoes gave him about 1,5 cm and he walked with a hunched back and when I looked at the tape it said 6'2" spot on.

What do you think Rob? I would bet he's still very close to 6'2.5" these days. :)
[Editor Rob: at 65 he may yet have escaped with only 1cm maximum lost...but displays at times more loss due to poorer posture.]
berta said on 22/Feb/17
haha yeah maybe thats true :P but yoga is the best thing i think. i really am 0,5 cm taller than i was 5 years ago asnd i think that can be because of yoga and then bodybuilding on side of that. This is something people should try. I have the last months tried and make my back as strong as possible and doing only row ecxercise and then for lower back that machine where youhave your legs back and your head down and then lift yourself up and down. i think you get what i mean. And really heavy like holding 60 kg when i do it. The cool thing is i have held track on my evening height and i can say my back is extremely strong now.some days my evening height have been in the 197,1 range and my morning height is about 197,8 and somedays little under that. somy tips for guys that will hold there height during the day and not loose more than a couple of millimeters, make your back muscles as strong as possible. And to get result i mean that you really need to get bodybuilder strong. Its not something many can do i guess but for the guys that already train give it a shout. But dont do deadlift if you do that you will be shorter even if you have strong back muskles. but excersices where you have at most 50 kg that you lift wont make you shrink. I remmeber when i was 16 years old i could be lets say 197 in the morning and then just lift things that weight maybe 20 kg for 15 minutes and i would have been down to my absolute low wich was maybe 195,6 back then. if i do semething like that now i will loose about 1-2 mm only even from my morning height. And then slowly loose the other couple mm during the first like 5 hours and after that it stopps
berta said on 11/Feb/17
just saw the video above about height workout. Best tips is really pull ups and hanging and then som eyoga poses like downward dog.
[Editor Rob: most people can't really manage a pull-up.]
Inteval said on 11/Feb/17
Hey rob my experiment with the inversion is still producing similar results. Before the inversion I would be 5 ft 11 in the mornings and 5 ft 10.25 before bed. Now I'm 5 ft 10.75 in the mornings, but 5 ft 10.5 before bed.

So even though I'm a quarter inch shorter in the morning, I'm a quarter inch taller at night. So am I shorter or taller?
Hamad said on 10/Feb/17
Hi Rob, I'm 172 flat in the morning, 169.7 in the evening, and 169.5 at night. Is 5 ft 7 a legitimate claim?
[Editor Rob: you can claim about 170cm, almost 5ft 7 at worst...since a big chunk of the day you are 5ft 7, only for last few hours, you fall under, I think it's fine to say 5ft 7.]
delancey said on 29/Jan/17
Haven't posted here since last year, gonna be a LONG post reporting back my own findings in the hope that they can help anyone who finds themselves on this page. I'm 176/176.5 out of bed, 174 and a bit during the day and a flat 174 before bed (have on occasion measured down to 173.5 if I've been to the gym and lifted heavy or if I've been slouching and or being just generally horrible to my spine/body for a couple of days but this is very rare).
Like a lot of these posts here I was hoping to try and squeeze out 1 or 2 cm's in my early 20's when I started paying attention to my height but I'm about to turn 25 so I can safely rule that one out now.
There is zero you can do if you've done growing and you want to INCREASE your height. Also as Rob says don't put all your hope into thinking that you will still grow in your early 20's as you are just setting yourself up for potential failure. I have personally seen this happen with a friend so it DOES happen but for me I think I was done growing by my late teens. BUT you can maximise and retain what height you do have!

Rob's advice is on point. Drink plenty of water! I'm talking at least 3 litres a day. Increased bathroom breaks are annoying but I really do feel like this is imperative.
Glucosamine does work as in it did RETAIN some of my morning height (obviously don't take it expecting to grow) but after a while I just got sick of taking it for the relatively minuscule effect (in the whole scheme of things) so I stopped.
Exercise, well you should be keeping fit anyway!
Yoga/Stretching and correcting/holding proper posture. Now THIS (along with water) is the most important part. Before I started a daily stretching/yoga routine I was a 174cm in the day guy who would drop down to 173cm as my low (3.5cm height loss from morning to night yikes!). Combined with TERRIBLE posture I most likely dipped into the 5'7" range at night. After about six months of incorporating a stretching routine and learning how to hold my body properly (for the first time in my life) I've seen a definite and obvious improvement! Disclaimer: My posture was absolutely terrible, had a high degree of anterior pelvic tilt etc. so I may have had more to "gain" than others.

So in summary correcting posture, stretching and staying well hydrated does actually work! (obviously). Again when my posture was horrible I likely stood shorter than 173 and looked like a 5'7" range guy at night but correcting it has made all the difference. You've just got to stick with it. I know it's only a cm (173 evening to 174 evening) but incorporating all of the above has helped my overall body/health, the benefits weren't just height based. I also feel a lot more confident and secure with who I am as well as opposed to when I started and I was very insecure/unhappy. Just go for it.
Rick said on 29/Jan/17
Hey Rob, my height is same as yours 5'9 in the morning and 5'8 before bed. Is it possible to increase with exercises or natural ways after age of 21? Like 1 inch or 2-3 cm, what do you think?
[Editor Rob: Rick, I think if you have the time, it is something you could test for 6 months.]
petra said on 27/Jan/17
hey Rob do you think glucosamine can help retain morning height..I'm 179.8 in the morning and 177.5 at night do you think it can stop me from dropping below 178
James said on 26/Jan/17
Hey Rob. If I'm 178 cm out of bed, 176.5 cm in the afternoon and around 176 at night, maybe a little bit over, is 5'9.5" a legitimate claim?
[Editor Rob: James it's not unreasonable to go with that figure.]
Inteval said on 25/Jan/17
Hey rob. With the inversion I'm having conflicting results. Normally I'm 5 foot 11 in the mornings but 5 ft 10.25-4 at night. After using the inversion for a few days I'm 5 ft 10.75 in the mornings but am 5 ft 10.5 at night each night. So even though I'm a quarter inch shorter in the morning, I'm only losing 1/4 inch in the day. And I'm sitting and driving a lot, so I don't know why this is. Could the inversion table make you able to maintain height better during the day?

Anyways, inversion takes up about 6 feet. Think about it if you have any space in your living room or garage. It's relaxing.
J.Lee said on 22/Jan/17
Hey Rob, I just got an inversion table. What I don't understand is I was a quarter inch shorter the next day when I woke up, after using it 10 minutes the night before. Can an inversion table make you temporarily shorter when you first adjust to it?

Also, Rob, am I allowed to change my username to something else?
[Editor Rob: yes change your name if you want, but don't have 10 names 😵 😳 1 is enough.

I'd need to test inversion table myself, but I have no room for such a thing, so can't say why you experienced a little loss!]
hambubger said on 22/Jan/17
Kevin, I lose the same amount of height - morning 187, before bed down to an alarming 184.5 cm.

I am a heavy guy and I wonder if this is why I lose an entire inch during the day (and most of it by lunchtime). What about you?

Also why does Rob give for example 184cm celebs anything from 6'0.25" to 6'0.75"? Why isn't the cm/in conversion done automatically?
[Editor Rob: all heights are stored in feet inches. The nearest whole cm value is displayed beside it.]
Timothy said on 21/Jan/17
Hello, Rob thank you very much for this information first of all. Do you think will it ever be possible to increase height naturally after age of 21? I mean, except bone lenghten surgery. Do you think will there be other methods to increase height after age of 21 in future? Maybe in 20 years or so... What do you think about this topic?

I did a lot of sports and had good diet when I was a child and in my teenager days. My father told me when I was born, doctors measured the baby height and they've said ''This kid is going to be like 6'2 (1,88) range in his 20s''. I am now 22 years old and I am full 1,88-1,89. My out of bed height is 1.90 full. So I think everything is about genetics because I had good diet and exercised even and did a lot of sports like swimming when I was a child. I think exercises won't make anyone taller or having good diet in their 1-20. its all about genetics and we can only add 1-2 cm max on it with sports in teenager years.
[Editor Rob: you never know with advancements in science. They may well find a way to generate new bone.

But I think in the future (whether 50 or 100 years), it will be gene engineering which will mean taller desired heights can be achieved.

The only problem is if everybody could become tall, then there is no basis for that...everybody essentially becomes more average.]
Tarik said on 20/Jan/17
Hi Rob. I've noticed what appears a small increase in height. I've been taking glucosamine and chondroitin for about 6 weeks and my morning height has increased to 177.1cm from about 176.6cm. Will have to monitor the measurements to see if it's down to error but I think it's an actual increase.
[Editor Rob: in some people it can give a few mm's boost to the discs, in some it won't...certainly means you might be a more comfortable 175cm at night.]
Yes yes said on 13/Jan/17
Rob, how will you react the day you wake up and measure yourself and see that you're not 5'8" anymore? ;P
[Editor Rob: I will snap the tape measure in half!

no, I would be happy to live long enough to even be as short as 5ft 6, I will take being 85 and 5ft 6 over dead in a coffin!]
Blake said on 13/Jan/17
Is it possible to recover lost childhood height? I was very sickly constant illness for a while till around 8, do you think I recovered this height now as I have since that age played sport and had no eating issue since?
[Editor Rob: I've read a research paper once talking about 'catch up' height, where the body in later teens can still catch up to genetic potential as long as it's being well nourished etc.]
Kevin said on 8/Jan/17
Hello Rob, when I wake up in the morning at 8.00 a.m I measure myself by using aerosol and I'm full 190 cm in the morning out of bed. In the afternoon, I'm around 189-188,5.

At night, (11.00 pm - 00.00 am) I am 187,5 if I had so much pressure on my spine and my back and if I sit on the chair for so many hours. Sometimes 1.88 at night or 1.87,8.

What height should I claim? Can I say 189 or 188? I am losing an inch (2,5 cm) in a very long day. Is that normal and is there a way to decrease the shrink effect?
[Editor Rob: Kevin, claiming 188 seems fine to me.]
Peter said on 7/Jan/17
Last question Rob
I had a foot injury when i was 18 (I fell from the tree). I have 5 non metal nails in the foot.I am 25 now and walk perfectly. The foot feels strong. Do u think there is some effect on height variation throughout the day?
[Editor Rob: Peter, I doubt it is effecting you too much, maybe a couple mm or so.]
Tarik said on 7/Jan/17
Hi Rob, I've measured myself a couple times in the morning and range between 176.4cm-176.7cm and the after a day's 12 hour work shift (which involves a bit of walking and lifting) I go down to my lowest height which is 174.8cm. What height or range could I claim.
[Editor Rob: Tarik, claiming 5ft 9 seems fine to me, or just say 175cm]
Rory said on 7/Jan/17
Rob,

What age on average would a man lose his first mm in height ?

Hey Rob
Does eating vitamin C make vertebral discs stronger? If they are stronger, i should shrink less throughout the day?
[Editor Rob: Pete, I don't know if it would have much impact, but I've read about glucosamine being able to help discs a tiny bit.]
Josef said on 30/Dec/16
Hi Rob!
Ive measured myself at night few months ago and i was 176 on the nose.
Now after a neck surgery(broken 7th vertebrae.) i measure 2cm less.
Even though i measured myself right after the accident and the surgery and my height didnt change at all.
But after few months after using my neck protector i shrinked 2.3cm when im almost recovered and my new vertebrea are reformed.(not fully for sure)

What the fu.k is that happened man. Im 26 years old. How is this possible?
Can i somehow regain my lost height?maybe i just have to wait a bit more to recover.
I almost cant accept this -from average height i went below when im so young without a fully maturized skeleton.
Maybe my bad posture? Through the wearing of the neck collar.

Anyway,i started stretches again. Few years before i had success with them(i growed an inch once!).
Rob do you think through some spine lengthening and posture improving(i have a very very poor posture after wearing this thing)
i can still reach 5ft9 at night? I would be very happy if i at least gain a ~cm, and stay on average.

I can tell you the shrinkage is fellable and made me very sad. Because if i were an old man. But seriously ive grown a bit few years back,ive a very good bone structure and never would have thought this could happen at my age. Even now i dont know where did i lose this inch from.I do not have an explanation. Maybe you have.
[Editor Rob: Josef, unfortunately it seems as though your spine has suffered a bit, but if I was in your position I'm not actually sure what I'd do - I'd probably be cautious and not want to risk doing anything which could make matters worse.

I certainly have read about people breaking bones in neck/back and losing height, so you aren't alone.]
Hapgood said on 27/Dec/16
Hi Rob, this answer may also answer a question that Francesco asked on 12/21/16 about how much height a man should lose on average by age 55. You answered a 1/3 to a 1/4 inch on average. I think in (most) cases that's a good answer, however there are exeptions to every rule. I will be turning 55 in early March 2017 in late December 1979 I was measured on a stadiometer [at PEAK ADULT HEIGHT of 66.5"] 139 lbs at age 17 years, 10 months. Please note that 37 years later in late December 2016 at age 54 years, 10 months I was also measured by a stadiometer at 66.5" 150 lbs. (the exact same PEAK ADULT HEIGHT 37 years apart.) Possible Reasons: ■ good back, ■ good knees, ■ good posture, ■ good health, ■ good sleep on a high quality mattress. ■ Working insde desk jobs/ light work vs. heavy grinding factory work.
[Editor Rob: I'd be delighted myself to hit 5ft 8 at 50 and would bite your hand off for 5ft 7.75 at age 60...]
Francesco said on 26/Dec/16
and another question.. at what age does a man start losing his first mm in height? do you think that at 50 a man can be still at his peak height?
[Editor Rob: many men will hit 50 and not lose anything, usually they have had decent posture, reasonably fit.

But there will be a big chunk who hit 50 and have started to lose a few mm's...they won't really notice, nobody would probably be able to tell that small 1/4 inch.]
Pierrick said on 26/Dec/16
Rob I'm 182 out of bed, 180, sometimes 179.7 at night. Wich height should I say about me ? Can I say 5'11 ???
[Editor Rob: Pierrick, about 5ft 11 might be something you can say...if Metric, simply 180cm]
Yes yes said on 25/Dec/16
Rob, with the thought of my dad being 6ft tall and that he was 5'5 at 15, how tall do you think I'll be at 21? I'm 5'11 1/8 in the morning and 5'10-5'10 1/4 at night and I'm 16.
My mom is 5'2 and my brother is 6'2.5 (He's 20). I remember asking earlier this year how tall he was he was 16 when finished 9th grade and he answered 5'9 1/2 but he also said there was a chance that he was 5'10 3/4.

So let's assume that he was 1/3-1/2 inch taller than I am at 16, do I have a good chance of reaching 6'2?
[Editor Rob: I did see a photo you posted, I would say you looked a typical 16, so not under or overdeveloped...I wouldn't worry much and just get on with being a teenager and only measure a few times a year.

Worry and stress may not be a good thing for growth.]

Hi Rob, never really got time to measure myself straight from bed or during the day only in the evenings I've measured myself at 5'9" after being awake 12 hours and doing a typical 9hr shift working at a supermarket working the stock so I never sit down would my average height be around the 5'9.5" mark? And could I claim that. Thanks!
[Editor Rob: Jas, there's a chance you might hit 5ft 10 or very close to it within 30 seconds of waking and be 5ft 9.5 at 10-11am]
Francesco said on 21/Dec/16
Hi Rob.
how much height do you think a man has lost by 55 on average? consider a man who doesn't have sport and have a sedentary job for 8 hours a day..

Out of bed my height is like 185.5 too 186cm (somewhere inbetween). During the day I hit about 185 - 184.9 cm. Now at 4pm I hit about 184.5 - 184. Stays at that level till' I go too sleep. Which Height should I claim 185cm or 184cm? Thanks for reading Rob.
[Editor Rob: if you say 184cm Mike, nobody is ever going to think you aren't that height.

Say 185, it's a slight roundup, but many in your position might go with that mark too.

personally I'd go with 184.]

[Editor Rob: if you died at 80 it is likely you would lose 1-3 inches (or even more in extreme cases) of height. If you reached 70 and died, you might lose anywhere from 0.5-2 inches]

Rob, do most of these average height studies publish when measurements are taken? Wouldn't they have pretty different findings depending on the time of day that people or measured or would it cancel out with a large enough sample?
[Editor Rob: some very specific studies might, but a general study will have varying times...on average I'd expect it to be late morning to lunch range.]

Which height should I go with?
The clock was 10 am today when I measured myself and I got rougly 5'10.75 - 5'11 when I was standing with my front against the wall and I had been awake for 2 hours but I was just lying in my bed.

But, here comes the funny part, a couple of minutes later I measured myself with my back against the wall and I only got 5'9.5 and I always get a shorter height with my back against the wall (Note: I measured myself with a Samsung Galaxy J5).

Plus that everytime I measure myself I always seems to get a too short height cuz when I measure myself at home my eye level is too high for that height and when I walk past the lines on the wall in my videos it looks like I'm taller and in school etc, there's a girl who said that she's 5'10 flat and that was over a year and now we're all 16 years old and it feels and looks like I'm about 0.5 inches taller than her.

A couple of days ago I got around 5'10 at 11pm so which height should I go with do you think?

I always say that I'm 5'10 when someone asks me but it feels like it's too short but my friend who said he was 6'1 this summer has his eye level at the end of my forehead sometimes and sometimes my eye level is at his nose.

Thank's for reading this! :)
[Editor Rob: Benjamin, I'd buy a big aerosol can (1 pound in poundland) like xantox and redo the measurement facing the wall about lunchtime.

Sometimes trying to measure yourself with back against a wall is more error prone, so it's much easier facing a wall.]

Hi Rob

When I wake up I'm about 5'8 - 5'8.25 and at the end of the day i'm 5'7.25-5'7.5

Which height should I claim?
[Editor Rob: about 5ft 7.5 range I'd personally go with.]
Benjamin Fritz said on 8/Nov/16
Hi Rob! I'm 16 right now and I'm 5'10 (I was 5'10 when I measured myself at 11pm today), my father is 6ft is my mom is 5'2 and my brother is 6'2 3/4.

Do you think I can reach 6'1-6'2 at 21?

My father told me he was 5'5 at 15 and my brother said he was 5'9 at 15 and that he was a little bit under 5'11 at 16.

By the way I LOVE your site! :)
[Editor Rob: there's still a chance of hitting 6ft, it might be useful to remember your brother's height at around your age, that could be a good indication of whether you could potentially get over 6ft by 20.]

Rob, my dad a was 5'11 peak height and 5'10.5 now and he already loss this 0.5" since 11years back i first visited this site and his now 61 and still holds a strong 5'10.5 when measure so could he be lower if he reach up 80s?

Because my grandfather was 84 and strange that he only loss posture more than height (look 5'8) but when get measure he still 177cm same time at his 70 birthday and a peak at 5'10 he doesn't loss much height my dad and i was surprising at it. My dad worried he would loss more height than my grandfather when another decades gone
[Editor Rob: probably 5ft 8.5-9 range by early 80's for him.]
John said on 6/Nov/16
Hi Rob, my morning height is like 183,5-184cm.
My evening height is like 182,7 cm.
Why would you say its my height?
Thanks.
[Editor Rob: John, just go with 183cm as your height.]
Jennie said on 4/Nov/16
Hi Rob. When shrinking starts at an older age, do women shrink faster than men? How much can the average 55 year old woman expect to have shrunk from her peak height? I am guessing somewhere around 3/8 - 1/4 inch.
[Editor Rob: a 55 year old might have typically lost a good 1/2 inch maybe a bit more, but some may lose barely anything or even an inch.]

Hey rob, how accurate is taking an aeresol can and using a tape measure in comparison to using the stadiometer?
For example, I measured myself with an aeresol can and measured 5'8 exactly at 12pm.
Then a week later I went for a physical and my doctor measured me at 10am and I was measured 5'7.25.
I have watched your videos and noticed when you measure yourself you lightly tap the stadiometer so it softly touches your head, when I was at the doctor there stadiometer wasn't lightly touching the top of my head it was more like dropped on my head and I felt as if it was pushing down rather than resting. Would this have a greater impact? Are my walls so slanted that I can achieve 5'8! So confused!
Thank you!!
[Editor Rob: because it is plastic, if you overtap it once it starts hitting your skull, then it might bend slightly and undermeasure...that might happen in your case.

I still feel it is good to try using some sort of aerosol can, but even then, if your floor slants slightly or your walls aren't vertical at 90 degrees, there's always a chance of slightly different measurements than what your true height is.

If you had several walls, or friends house with better walls, it might be useful to test on these other walls..]

I measured my girlfriend at 9:00 PM and she was 5'6" and 1/4" Can she claim to be a legitimate 5'7"?

I measure 5'11" first thing in the morning at only 5'10" later in the day. Can I claim to be 5'11"?
[Editor Rob: if she drops that low, I wouldn't call her 5ft 7, maybe 5ft 6.5 she could claim.]
Judd said on 8/Oct/16
Rob it's possibile that a man of 75 years (male) recorded a loss of 0,5-0,75" from his peak if his body conditions are good (any injuries) and his posture is good?
[Editor Rob: he would be beating the average by the same amount...it is very possible, but the proportion who only lose half inch or so by mid 70's is smaller than the the proportion who will lose between 1 and 2 inches by that range.]
Alex said on 29/Sep/16
Hi Rob,

I§ve measured myself right out of bed and I§m always between 5ft 8in and 5ft 8.25 in. I§ve also measured my height right before going to bed and here is the strange part: on weekends and holidays I'm 5ft 7.5in (or a few milimeters more), but on weekdays I'm barely 171 cm or even 5ft 7.25 in. I know it§s still 171, but half an inch seems quite a lot considering it§s my lowest height. I have to mention that on weekdays I usually carry a laptop (which is about 4-5 lbs) in my backpack and I walk about 1 hour with it (30 min from my house to school and 30 min from school to my house).

My question is: do you think that the extra weight I carry (because of my laptop) could be the responsible for the extra 1/4 inch that I lose on weekdays??

I'd appreciate your answer!
[Editor Rob: the extra weight could effect things a little fraction. I know when I carry stuff in a backpack and have checked my height, I will hit my low quicker - sometimes at 1pm I'm down to my low after carrying shopping home in my rucksack!

another little factor that may effect our fluctuations is hydration - becoming a bit dehydrated may result in hitting your lowest height quicker.]
Jm19 said on 28/Sep/16
Hello Rob,

I measure 5ft 10 out of bed but by the end of the day I measure about 5ft 8.5! I am overweight (17.5 stone) do you think my weight is the major cause of my height loss throughout the day?

Thanks a lot!! Love this website!!!
[Editor Rob: you are not that much overweight...it's a helluva loss from morning till evening, I mean I'd expect a 6ft 6-8 guy to possibly shrink that.

Ice said on 27/Sep/16
ROB my Job requires me standing and hunching over for a long time do you think I have a lower night height because of this ?
[Editor Rob: long-term it might effect your height, possibly accelerate any losses.

If I were you I'd try some basic daily stretching to counteract the effects of your job. Reach for the sky, touch toes...really simple stuff.]

Hello Rob,

right out of bed i measure at 172cm. After a long day at work, sainsburys, right before bed i measure at 170cm. I recently changed my diet, started drinking 1.5 gallons of water per day, started taking glucosamine pills, working out, and doing 5 minutes of hanging excercises, pull up bar excersises and also thinking about going to a chiropractor to help with my terrible posture and straighten out my back.

do you reckon over a period of time, lets say 6-12 months, i can improve my morning and late night height? How much do you reckon i could gain?

Thanks and keep walking tall like Rob Paul haha !!
[Editor Rob: I'd say don't be disappointed if you only managed an extra cm overall.
I would definitely give that routine at least 6 months and then assess your morning/evening again to see if it has improved. If it has, then do another 6 months.]
TTstar said on 7/Sep/16
Hi Rob! Can sore muscles at the back cause you do shrink more? I noticed that i measure a little smaller (3mm) since my backmuscles got a little sore last week.
[Editor Rob: it may effect your posture and inhibit your ability to stretch up as tall as you normally can.]
Christian-196.2cm (6ft5.25) said on 5/Sep/16
[Editor Rob: yes that is quite long for your height, 34-6 might be a more common range near 6ft 4-5.]

-------------

How about my arms Rob? My wingspan is only 76" (6ft4), which is a bit below average for my height, but my arm length (the tip of my middle finger to my shoulder) is 34.5" (88cm). Is that rather long or short for my height? NFL's Cam Newton is around my height and he has an arm length of 33 3/4" (86cm) Click Here
[Editor Rob: with a narrower ribcage/shoulder width, armspan of 6ft 4 might still appear long, like in your case.]

I wake up at 198.4cm (6'6 1/8'') and go to bed usually at 196.2cm (6'5 1/4''). It has been said that the average person lose 3/4" from morning to night, but I'm not average-heighted, so it's understandable to lose 7/8th of an inch over the course of the day. And my inseam is 36", so I would say my legs are slightly long in proportion to my height.
Gerry said on 24/Aug/16
As a reference for your Rob, based on you being 5ft 8in, if you stood beside me, you would be at the middle of my mouth (I meant to have this on the previous post), which is similar to most of the guys that you had beside you that you list at 6ft 4in, but 5ft 9in is at the bottom of my nose, and its 6.5in from there to the top of my head which would most likely lead more to 6ft 3.5in. So just curious as to what you would list me at, and sorry for the delayed postings and long winded posts.
Gerry said on 24/Aug/16
Hey Rob.

Yes, it is quite the shrinkage, and further to your comment, chances are I do have thicker than normal discs that hold a lot of water and expel more throughout the day.

But to add an extra component to it, because of my muscle/ligament/bone/joint condition (in short my bones outpaced my muscles and left my incredibly rigid (hyper-inflexibility)), I technically am not ever going to be at my full height because if I could straighten my legs and have my spine corrected (it's on a bit of an angle (but unnoticeable on the outside)), I would be six inches taller.

Also if they could correct my overly rounded shoulders, I would have a 6ft 11in arm span instead of a 6ft 6in arm span (which used to be longer since as of 1995 I was 6ft 1in tall with a wing span of 6ft 7in and I wasn't done growing yet back then).

When I graduated high school I had an 11pm height of 6ft 4in and considered myself to be a solid 6ft 4in tall, and possibly even 6ft 4.5in tall, since in basketball I would have been listed at 6ft 6in after I was measured in my 1.5in basketball shoes at a little over 6ft 5.5in and then was measured at a later date around the same time frame in a pair of 1in dress shoes at 6ft 5.5in, but with all of my shrinkage that has already occurred and continued to re-occur since that time, and the fact that I have not been keeping up with my prescribed stretches for quite some time, I no longer consider myself that.

Additionally, once i shrank below a 6ft 4in afternoon and/or evening height, whether it was a strong 6ft 3.5in or 6ft 3.75in, doctors would write down 6ft 3in, so they would technically round me down from 192.5 cm to 190.5cm, and then round that down to 190 cm, so that is something I initially found frustrating. But oh well, it could be worse.

Most people have refused to believe me when I say that I am 6ft 3in/6ft 4in, even though I am in a medically documented study and in published book at 6ft 3.5in, and insist that I am 6ft 5in, 6ft 5.5in, or 6ft 6in. Overall my height has been somewhat of an obsession and frustration of mine ever since I was a 6ft grade 8 student, but for the most part, I have gotten over it, and in my current decade of life have been more annoyed because there are too many people that I have met that are using inflated basketball player-like heights, and need to be more realistic about their own height, and stop lying about it, as far as I am concerned, .

However, although my passport says 6ft 4in, and I was told to round up to 6ft 4in on acting resume, I consider myself to have had a peak height of 6ft 4in, an overall listed height of 6ft 3.5in, and a current height of 6ft 3in due to my more recent shrinkage, but when anyone asks me, "how tall are you?", unless I feel like rounding down, I answer 6ft 3in/6ft 4in, a little over 6ft 3in, or sometimes I answer 5ft 7in for fun :) , but usually I answer with my most regular consistent natural answer of 6ft 3.5in.

So I am curious Rob, taking everything into consideration, what would you put as my peak height, current height, and overall height - i.e. how tall would you list me at if I were a celebrity on this site?
[Editor Rob: I'd have went with your peak height somewhere around 6ft 4.5, now maybe a bit under 6ft 4...

I wonder though, if you started a simple program of 3 minutes hanging and basic stretching (reach for stars, touch tip toes) for a few months, whether your height improved a bit more and you regained some which seems to have been lost.]
Gerry said on 23/Aug/16
Hey Rob.

Although I have a condition that has already caused me to shrink and then attempt to re-stretch back to where I shrank from, three times so far in my life (I am only 35 years old), since I get a kick out of your site, and further to this height loss discussion thread, in recent years, I have taken a few occasions where I measured myself over an 18 hour period, and wanted your thoughts as to the daily shrinkage, and what height(s) you would consider me to be.

2010: 6am: 6ft 6.5in, 9am: 6ft 5in, 12pm: 6ft 4.5in; 3pm: 6ft 4in; 6pm: 6ft 4in; 9pm: 6ft 3.5in; 11pm: 6ft 3.5in

2011: 6am: 6ft 4.5in, 9am: 6ft 3in, 12pm: 6ft 3in; 3pm: 6ft 3in; 6pm: 6ft 3in; 9pm: 6ft 3in; 11pm: 6ft 3in

2013: 6am: 6ft 5.5in, 9am: 6ft 4in, 12pm: 6ft 3.5in; 3pm: 6ft 3.5in; 6pm: 6ft 3.5in; 9pm: 6ft 3.5in; 11pm: 6ft 3.25in

2015: 6am: 6ft 6in, 9am: 6ft 4.5in, 12pm: 6ft 3.5in; 3pm: 6ft 3.5in; 6pm: 6ft 3.5in; 9pm: 6ft 3.25in; 11pm: 6ft 3in

2016: 6am: 6ft 4.5in, 9am: 6ft 3.5in, 12pm: 6ft 3.5in; 3pm: 6ft 3.25in; 6pm: 6ft 3.25in; 9pm: 6ft 3in; 11pm: 6ft 3in (and I had a couple of times it was as low as 190 cm/6ft 2.75in)

Thoughts?
[Editor Rob: as I said, it seems an extraordinary shrinkage, something I would love to witness, because that amount of shrinkage would be visible to many people. Maybe you have discs that are thicker than normal or hold a lot of water and then through the day expel much more than ]

9 hr mark: 6ft 3.5in
12hr mark: 6ft 3.25in
15hr mark: 6ft 3in
18hr mark: 6ft 3in

When I graduated high school I was 6ft 4.5in at the 9 hour mark and 6ft 3.5in at the 18 hour mark. The above results are me at age 35.

George said on 3/Aug/16
Is it weird for a man being 25, losing 7 cm in height since 16? If in 16 I was like 175 cm and 113 kg, but now 168 cm (maybe 169 cm in the morning) and 52 kg? Also I was 172 cm by the time I used to weigh around 75 kg, at 21.

I'm not crazy, but it happened. Others who knew me from before and had to see me for a long time, noticed I'm being visibly shorter as well. And neither some strange disease occurred, according to recent medical exams.

I don't know if it had to do with massive weight loss, or just God heard my prayers. Actually I don't feel well being tall, I find it awkward looking down on others, so I was keep praying getting shorter (yes I believe in God.).

I just wanted someone else's opinion. Also my feet shrank like 3-4 European Sizes. (From 43-44 to 40)
James Edward Crowley Maximus Meridius said on 25/Jul/16
Rob is it possible for men too be 6ft 3in in his 20s and shrink too 5ft 6in in his 80's going from 6ft 3in too 5ft 6in would be a lot of height too lose that is a 9 inch height loss what's the biggest height loss you heard of.
[Editor Rob: extremely unlikely, but there may be cases of people who lost 8 inches, those who lose more might suffer condition which means spinal collapse! ]
Kourosh said on 22/Jul/16
Thank you rob for answer. My shrinkage varies from 1.8 to 1.5 cm but on average i wake up at around 177.6 fresh out of bed and at night i am 176 cm on the nose take or give a mm. i hope my height shrinkage is withing normal range?!

I usually sleep for 6 hours , if i sleep up to 8 hours , does this mean my morning height will be taller like 178 cm or more?
[Editor Rob: if you got 8-9 hours, well hydrated night/day before and managed to sleep mostly on your back you may hit your highest which could be a couple of mm or so taller than normal morning height range.

1.6-1.8cm is a very common range of shrinkage.]
Broman said on 22/Jul/16
Hi Rob, I'm 23 and was 5'9 flat and got a bit obsessed with wanting to be the same height as my brother. I managed to increase my morning & night height by 2cm from sleeping on the floor and taking glucosamine! Crazy I know! I'm now within 1cm of my brother. So I succeeded I guess.

I now range from 178.5cm - 177.5cm, do you think my night height still counts as 5'10? I mean it's 3mm off and 4mm above 5'9 3/4..

Thanks!
[Editor Rob: it's enough to be consider roughly 5ft 10]
Merky said on 20/Jul/16
I remember reading about height loss and thinking it was bull, but then when my Aunt visited from Canada she looked about 3 inches smaller than I remember. Either I had grew (unlikely) or she had lost quite a lot!
Kourosh said on 18/Jul/16
Rob, i lose about 1.2 cm within 45 min after waking up. is this normal? you only lose a cm after 1 hour after bed i saw your height shrinkage video on youtube
[Editor Rob: if you have a bigger overall shrinkage, then 1.2 is within a typical range, I think some may lose less than 1cm, others a bit more...some men or women can shrink 2.5cm and be under 6ft.]
Heylo said on 4/Jul/16
I go down 1.2-1.4 cm after a a whole day. My height is 178.2 in the morning and 177cm or sometimes 176.8 in the evening. Is this normal? I saw some comment about the average shrink though the day being almost 2cm. What could make some people shrink less?
[Editor Rob: it means your discs don't lose as much fluid (seeps out) during the day. 1.2 is less than average, nearer the lower range of the scale.

I think the older you get the smaller the morning-evening shrinkage can become.]

Hi Rob should I be concerned I'm 42 and have recently notice a change in my height I was 5'5 so the other day I measured myself after friends and family have been commenting on my shrinking over the last couple of months and I now measure 5'1
[Editor Rob: if you've lost that amount then I would suggest asking for a Doctor's appointment and then if he hears you've lost a few inches he will likely get x-rays and tests done to determine if your spine is degrading badly.

There are some conditions where big losses can occur.]
delancey said on 1/Jun/16
Hey Rob, I'm 176 and a half in the morning and a flat 174cm before bed (174 and a bit for most of the day). Just wondering does a 2.5cm daily loss seem normal for a healthy 24 year old male? Reason I ask is that it seems a lot to lose for someone my height as I already stretch daily (as part of my every day fitness), I don't slouch and also definitely drink more than an adequate amount of water. I'm just a bit concerned that I'm losing that much for a guy of my height/age. Any further ideas on how I could maybe minimise it?
[Editor Rob: about an inch is a fraction more than average, but many lose this, even Jenny (my partner) lost a full inch most of the time.]
Hephaystos said on 1/Jun/16
Rob, in my previous question i asked you how i guess a person height if i'm eye to eye with him. you answered that he's "1 cm within of me", what does it mean? that he could be 1 cm shorter or taller than me? sorry but i'm not a native speaker
[Editor Rob: because different people might have higher/lower eyelevels, looking eye-eye is a rough guide. They may well be fairly similar, but they could even be a fraction taller/shorter.]
Hephaystos said on 23/May/16
Hello Rob, a question. my 57 years old uncle who is very sendentary and work a lot at computer since his 30's (so not standing straight with his back almost all day), how much height could have lost in cm? another question. how do i guess his height if i'm in front of him? we are more or less eyeleveled.
[Editor Rob: if you are eye to eye he really will be within 1cm of you.

He could have lost 1cm, it would be more unlucky if he lost 2-3cm at his age.]
SportsHeight said on 17/May/16
Rob, what can a fit healthy guy in his 20s who's around 6'0.5" in the afternoon realistically expect for height loss going forward, assuming he eats and drinks well, stays fit, maintains good posture, and stretches regularly? When would he start to lose height and how much would it be at 50/60/70/etc.?
[Editor Rob: I would expect by 50 for him to have lost a little fraction, but to most people it won't be noticeable.

By 60 he might get away with just between 1/4 and 1/2 inch...I'd say 1/4 inch if he maintains fitness and does regular stretching and eats decently.

The 60-70 zone is where a lot of people start to really notice losses. I would still expect overall between 1/2 and 1 inch lost even for a relatively fit and healthy guy by age 70.

Hey Rob, my Dad claimed he was 6'1,5" when he was in his 20s but his physical in his late 40s said 5'11.75" and now it says 5'11". I'm thinking his peak height was probably more like 6'0-6'0.5" and 6'1.5" was his height in shoes?
[Editor Rob: yeah that sounds more like it, unless he really lost a fair chunk through his 40's. Some people develop bad habits and posture and by the time they get near 50 they have lost height not only in terms of bone density/cartilage loss, but also the curve of their spine has altered.]
NFL said on 16/May/16
Would you say NFL combine heights are as accurate as it gets? FWIU, Players are measured between 9am and late afternoon. So a guy like Derrick Henry who measured 6'2 5/8 recently, his morning height would be about 6'3 and his average/afternoon height would be about 6'2 1/2, correct?
[Editor Rob: I would say the database is probably 99% accurate...there will be some errors, be it the reading was wrongly taken (like the guy called out 3/4 and he was on the half inch mark etc...but those should be a small amount.
Also data entry error - always a chance of some errors creeping in through typing.

As for the time, it certainly won't be evening measurements, I'd say on average though the players will have been up a couple hours so have already lost a chunk of height...might be like a 10am type measurement.]

hey, question here bro

I notice to lose about 0.5cm everytime i go over a week without stretching

Am I right or is it just normal that my height can differ day to day at the same time?
[Editor Rob: the stretching might be helping you retain a little bit extra, so I would try to keep doing it.]
Francis94 said on 26/Apr/16
Hi rob. How much height do you think a man have lost at 55? On average
[Editor Rob: about half inch maybe...sometimes a bit less or more depending on various factors like job, overall health, injuries etc.]
slothee said on 25/Apr/16
If my dad is 5'6.5" at 57, what do you think his peak height likely was? (assuming he's shrank at all)
[Editor Rob: probably nar 5ft 7 ]
dave said on 18/Apr/16
I am 24 years old and i started to jog for like 6 months i saw a 1.5cm increase in my height. Prior to this i have not been exercising for years. How is this possible?
[Editor Rob: certainly strange, but then maybe somehow it helped your height a bit!]
Canson said on 12/Apr/16
Rob: you mentioned this a while ago but was it your morning or evening height that increased with age?
[Editor Rob: evening height hasn't really changed, but I did at one point get a few mm higher morning measurement. Typically in the past (10 years ago) I'd get 5ft 8.6 range, but for a few years got 5ft 8.75 range, sometimes a tiny bit more (using tape measure and wall measurements).]

Out of bed height is useless. Early morning height comes off soon. Nobody will notice because the other person who see you also are in morning height around you. It feels the same, except very tall people who can appear taller yet compared to normal people
Ice said on 3/Apr/16
ROB Ive been drinking a lot more water lateley , and Im pretty sure my morning height measurments have gone up a bit . But how long would it take to fully rehydrate the discs ?
[Editor Rob: maybe a number of days keeping well hydrated let's your body rehydrate properly]
KJD said on 1/Apr/16
hey rob, for example: a celebrity would say: "I'm 5 feet 11 out of bed"...would you list him at this height (assuming of course he looks like it in person)? i have another question...the height you reach out of bed, is that the "maximum final height" of growth or the height you reach after 5-6 hours after waking?
[Editor Rob: maybe half inch or three quarter inch under their morning height, unless they actually said something like 5ft 11 out of bed and 5ft 10 at night, then maybe 5ft 10-10.25]

Mr S said on 25/Mar/16
@Rob: I know a lot of articles say that height loss begins at around age 30 but that seems a bit too young unless they mean mms. At what age would you expect the average person to have any real hight loss, like 1cm?
[Editor Rob: there was a long-term study on loss and pretty much the average losses were: By age 40 Men: negligible Women: few mm's By age 50 Men: 0.5cm Women: 1-1.5cm By age 60 Men: 1.5cm Women: 2.5-3cm By age 70 Men: 3cm Women: 5cm]
Fer said on 18/Mar/16
Rob, My height straight out of bed is 173-173.5 cm and my height at night is around 171.6-172 cm. What would be my real height?
[Editor Rob: both heights are real, it's just nobody really sees you at your early morning height, but most people see each other at the height after being up several hours (which is much closer your low height). I think if people went with a mid-day or evening that is fine...if you ever say your morning height, best to tell people '173 in the morning'. Then, there's no confusion.]

ROB a couple of weeks ago I measured 189.1 cm each morning , after a good night sleep of roughly 8 hours . The last couple of weeks Ive been waking up each single night , and staying awake for like 10 minutes , in this time I loose about 0.5 cm of height . And I sleep like 7.5 hours each night , since the beginning of these mild sleep problems . Since then , my morning height measurments have decreaced , I only measure 188.5 - 188.6 !Could this have something to do with not getting a good night sleep of 8 hours , without interruption ? Im only 18 so I really dont think I permanentley shrank . Thanks .
[Editor Rob: it is unlikely you have shrank...but it might be your body isn't as well hydrated as it had been. That might account for a few mm's...as can the position of your body whilst sleeping.]

Thanks Rob...
Verona Rios said on 28/Feb/16
Rob, I would very much appreciate your opinion on that: my sister was measured 175.4 cm three mornings in a row and 173 cm sharp by he time of bed the same days (all the times with a stadiometer). What height in centimentres should she officially claim (in centimetres)? Thanks for anwering
[Editor Rob: if she says 173cm nobody will ever say 'you don't look it'...in fact I would bet many would guess her 174-5 range... it's really up to her. Say 173 or 174. 174 is more like an average of her morning/evening.]
Kourosh said on 27/Feb/16
Dear Rob today i notice something , i woke up fresh out of bed and i was right around 5'10 (177.6 cm) but after 3 hours i measured myself again and i was only 176.2 cm. why i did lose so much of height in just 3 hours? is this normal?
[Editor Rob: the younger you are, the better or 'spongier' your discs may be...so it's not uncommon when 18-25 to have a greater overall morning-evening shrinkage than when you reach 50's or 60's. In your case, it isn't anything extraordinary...the first few hours of being up and about will result in a fair whack of your morning height diminishing.]
Kartik said on 20/Feb/16
Hey Rob, my height straight out of the bed is 184.5cm and my night height is 182.9cm. what would you say my true height is??

Judd said on 9/Feb/16
Rob how may be the loss of a person (in cms) of 75 years old who has not particularly back problems and made a lot of sport activities during his 10s,20s and half 30s?
[Editor Rob: for a male about 1-1.25 inches I'd say...he may still lose more depending on factors such as diet, whether he smokes/drinks and how active he keeps from 50-70 range. I'd recommend keeping active as you get over 60...too often it's easier to jump in a car, but even walking sometimes to the store will help.]
MB said on 7/Feb/16
After age of 80 does shrinking stops or how much do you shrink each decade after 80? Suposse I am 6 feet at 40, by age of 100 I'll be 5'8" or what?
[Editor Rob: you can keep shrinking...if you reached that age, I'd expect 3-4 inches lost.]
Tishah said on 1/Feb/16
Hi, I'm 20yo F, and I used to measure at 165cm. In a year (when i was 18/19), I lost 20kgs, and now I weigh 48kgs, but my height has also decreased. I'm now 160cm. I know this is correct as I used proper measuring scales and did it almost every day out of pure boredom when working in a health clinic. Other people have also noticed my decrease in height, and it's obvious when looking at photos. Is weight loss associated with height loss? I just thought it was a bit strange to be shrinking so drastically at age 20. Thanks!
[Editor Rob: it shouldn't make a difference...5cm is an extreme amount of difference between those measurements. I couldn't explain it, unless there was something that changed with the measuring rod...]
TheTruth said on 31/Jan/16
Rob, how much height does a male loose during the day on average in centimeters?

Hi Rob, my morning height is 174-173.7 and my night height is 173, but when I come back from school my height is only 172, what should I go with?. I turned 18 last month, so is it possible to grow 1-2 cm? or I stopped growing? Thanks in advance.
[Editor Rob: I'd say 173cm is ok to claim, or just 5ft 8. At 18 it can be a coin toss as to whether you are completely finished or maybe still 1-2cm left in the tank.]
Brian said on 22/Jan/16
Hey Rob. Yesterday morning straight out of bed, I measured 5'11 7/8" and then about 8 hours later, I measured at 5'11 1/16". Do you think it is fair to claim 5'11 1/2" as my height?
[Editor Rob: it's what many people do, go with the average range. At worst you are about 1cm below your claim, so nobody really will spot that. if it was an inch maybe they might.]
James said on 15/Jan/16
Isn't morning height your real height instead of your height in the evening? Yes, the spine compresses temporarily over the course of the day. However, most people give their weight in the morning after getting out of bed as their real weight, so why should it be any different for reporting one's height?
[Editor Rob: we all have a morning-evening range. If everybody agreed to give their morning height then we'd use it, but most people never get measured first thing out of bed.]
Ian C. said on 14/Jan/16
Is the height loss gradual or abrupt? My guess, having done no research, is that it is abrupt. I am 64, and know something about the robberies that befall you as you age, and things just go. One day, for example, you have an unlined face, and then suddenly you notice that you have wrinkly eyes. Stuff like that. I'm guessing in the case of somebody like Clint Eastwood that he was very close to his young adult height until he was nearly seventy, and then his spine went extra curvy on him. That would be the way to bet.
[Editor Rob: I think it can happen in spurts ]
Hi said on 12/Jan/16
Rob, My height straight out of bed is around 173-173.5 cm and my height at night is around 171.9 or 172 cm. What would be my real height?

If person is healthy and lives healthy, height loss occurs after 60.
Garrett said on 1/Jan/16
Rob, my height straight out of bed is 6'2.5" and evening height is generally a bit above 6'1.5". Is this amount of height loss normal? It seems a bit much to me, I am 16.5 years old and do not consume enough water, if that is a factor. I also lose the first half inch in about an hour out of bed, and spend most of my day around 6'1.75", if not a bit under. What height should I claim?
[Editor Rob: it's very normal to lose 0.75-1 inch. you could always go with about/almost 6ft 2 as a claim.]
Clark said on 29/Dec/15
So Rob men start losing height in their 30s (I couldn't imagine say a 35 year old being much shorter than their peak)? That seems a bit strange since most men don't completely finish growing until their early 20s
[Editor Rob: I think it would be more like late 30's an age that some very small losses could start to occur. They could be earlier if you have injuries or jobs that involve a lot of wear and tear on cartilage, but we are still talking a small amount. The majority should make it to 40 without barely a loss.]
datguy said on 25/Dec/15
Hey rob, Out of bed I measure a little over 5'10 but by the end off the day right after a workout I'm 5'9.25 Do you think it's ok for me to claim 5'9.5?
[Editor Rob: yeah that is perfectly reasonable to claim.]
FrankIta said on 24/Dec/15
Hey Rob. I have two question. 1) my dad is 54. how much height do you think he has lost till now? and second question.. since i was 15 i had a 1500/1800 kcal/die diet with a lot of sport. do you think this could have negatively affected my height growth? i was 168cm back then and now at 22 i'm 176cm.. i'm as tall as my dad, while my mom was 163/165 cm. thanks
[Editor Rob: diet can play a role in whether we reach our true genetic potential, but how much is unknown. You could be talking a fraction, or with malnutrition 1-3 inches. At 54 the average loss for a man is a fraction. It isn't impossible he was near a cm taller in youth, but then many guys can get to early 50's without any loss...getting to early 60's without any loss is harder. The majority will have lost a fraction at least by then.]
KJD said on 21/Dec/15
Hey Rob, I'm 180,6cm out of bed and my evening height is 179,6cm; could I claim 5ft 10.75in (roughly 180cm)?
[Editor Rob: it's not much shrinkage, so saying 180cm is perfectly fine.]
Jordan said on 18/Dec/15
Hi Rob, I measure in at 179cm in the morning and 177cm at night (8am and 10pm). Would it be fair to say I'm 5'10"? Or is it better to use the evening height? I want the most accurate number ideally when using it for BMI or TDEE however. Also, after doing squats or Deadlifts I can measure under 176cm! But this always returns to 179cm in the morning, do you know if this is normal?
[Editor Rob: extreme circumstances can make us shrink to an 'absolute low'. For instance, doing an intensive sport like tennis/soccer/football or big weights. Measure straight after and your discs have been put under a helluva lot of pressure, so will have compacted a fraction more than usual. In your case I'd say that you were 'about 5ft 10 or almost'. If I was saying the metric value, I'd just say 177cm though - nobody then will think you are lying, because people half expect others to lie a bit about height...]
Jhl90 said on 15/Dec/15
Hello rob would you say being overweight can cause a big fluctuation in height ? I'm 22 and straight out of bed I measure 5ft 10.25 but by the time I go to sleep I'm 5ft 8.75 .. I'm 17 stone but quite muscular on top with a fat midriff.
[Editor Rob: seems a huge amount to lose at your height. I don't know about the excess weight, you're not exactly huge at 17 stones.]
madison ogren said on 24/Oct/15
im 5'7 and i dont like my height its so agervating i want to be like 5'2 or something because i want to be able to wear heels whenever i want without people looking at me weird.

Dan said on 12/Oct/15
Hi Rob! I'm not sure exactly how tall I should say I am... Could you help me please ? If I measure myself first thing out of bed, I am 195,5 cm. At noon I am 194,5 cm. At the end of the day, after a good workout, I reach 194 usually. And my absolute lowest is 193,5 cm. What height should I claim? Should I go with 194? Thank you very much!
[Editor Rob: I think saying 194cm is the option I'd use if I was that tall.]
John said on 5/Oct/15
The measurements that I took were always in the hallway on the laminate flooring, although not always at the same spot but they were less than a metre apart so I can't see much difference in the sloping. Yet again today another person at college said I looked shorter, as if I'd shrunk. I'm really unsure what to do about it now as it's not just a one off occasion where one person made one comment about my height. Do you recommend I get this checked out in some way?
[Editor Rob: I'd say if you had any back pain then maybe look into it, as slipped discs or disc problems could cause a fraction difference...if not, maybe it's worth trying some basic stretching for a few months then remeasuring and seeing if it was posture-related.]
Smith Western said on 4/Oct/15
Hey Rob does being obese mean that you lose more height during the day? does weight affect how much height you lose??
[Editor Rob: I've never seen any study trying to examine it, but if there is any effect I think it is for extreme weights like 10 stone overweight, not 3-4 stones overweight.]
Felix said on 4/Oct/15
Hello Rob, two months ago I have been measured twice, at the end of the day (and after workouts), at 180.5~181cm. But then, last saturday I decided to measure myself against a wall just after I woke up, and I got surprising 184,3cm (indeed I never felt I was that height, it was a positive surprise). How tall do you think I really am? Do I shrink 4 cms during the whole day? My personal opinion is that this is quite a lot, idk, maybe I am 182cm and the weight of bags make pressure upon my spine. By the way, since I am only 19, do you think there's chance for me to grow until a full 6'0? Can I claim to be these 6ft tall? Is this range 181~183cm a good height for a brazilian?
[Editor Rob: 4cm is a huge amount, but some guys do shrink 3cm, and the younger you are, the more the discs in the spine can rehydrate/expand to a fuller amount. You are tall in Brazil, the average is still nearer 173 than 181-2cm.]
John said on 3/Oct/15
Hey Rob, my concern is increasing for my height. At 16 I was a solid 5ft10 throughout the day and now at 17 3/4 years old, by evening I have dropped notably below this mark (1/3rd to 1/2 of an inch). I'm fully aware of height loss throughout the day and I take this into consideration. I also always measure carefully as I know about mismeasurments. A few days ago, a girl and I both decided to compare our heights again barefoot. She is the same year as me in college but older. 3-4 months ago, I was roughly 3/4 of an inch taller than her when standing up straight and looking into the mirror as well as measuring standing back to back (as done in your celeb photos). This measuremeant was actually around 11pm. Now, she's 1/4 of an inch bigger than me. This is highly unlikely for a girl who's actually very nearly 18 to grow nearly an inch, especially considering her height already. Both these height comparisons were done on an even surface. As well as that, on the same day a guy in the year below said to me how I'm not that tall anymore and that I don't look as tall. This isn't the first time someone's said this to me. It's starting to get to me and affect my confidence. So I was wondering if there is any possible condition or disease that may have caused this, even if it is an unlikely cause. Thanks for the reply in advance :)
[Editor Rob: it seems a strange occurence. While injuries can knock height off and dehydration can knock a fraction, your case seems to be unique. It's not impossible a girl near 18 could gain height, some still do... also, with measurements, it really can give differences even if we think the wall/floor looks straight. I did a Video last week showing that carpet really can knock a good chunk of height from your measurement...but also if you watch my second measurement and then the third, that is still a big difference...just a slightly sloping floor can knock a 1/4 or 1/3rd from your height!]
Michael said on 2/Oct/15
Is it normal to Shrink over 3cm over a daily basis? I am overweight
[Editor Rob: the average is nearly 2cm, so 3cm is a fair bit more than average, but not extreme...4cm is more in the extreme range, you'd expect that if the person was very tall though.]
Ray said on 30/Sep/15
Can stress affect height? I have been stressed because of circunstances for around last month, I measured myself yesterday and i found that my lowest was around 0.25-0.5 inches lower than usually. I am sure this is not due to age because i am young, but i am not sure if i will recover the height loss...
[Editor Rob: it seems an awful big difference. I really can't think how stress would make you shrink more, unless it was somehow effecting your hydration levels or your ability to stand as tall as you used to stand.]
John said on 29/Sep/15
Thanks, my guess is that tall people have longer legs than spine, but that might not always be the case. My sisters ex boyfriend was 6ft 3" and me 5ft 9" and yet we were the same height when we sat down, so he had long legs. I assume that if tall through long legs then the height is little effected with age compared with a shorter person as if both have the same spine height then both will lose height at the same rate through the spine. Interesting concept though and thanks once again for your good response.
John said on 28/Sep/15
Do tall people lose much more height than shorter people as they grow older?
[Editor Rob: proportionally I think when you have longer spine you have more chance for greater loss.]
Magic said on 10/Sep/15
If I drink poor water less 1 liter during day ,do I shrink faster? 3 cm loss after 5 hours for example! Rob , do you suggest to drink 2 liters everyday for loss less water of the spinal column and so shrinking more slow?
[Editor Rob: when the body becomes dehydrated it uses water content from within, like soft tissues...so being dehydrated a lot might mean your discs lose more height than normal and you shrink more than if you were better hydrated through the day. I'd advise taking regular drinks of water.]
Paolo said on 5/Sep/15
Since I turn 18 Ive only been measured at 8 at night after being up since 7 in morning......i was 5'11.5 Is it safe for me to say i,m 6 feet if people ask my height? Thank you
[Editor Rob: you could go with almost/about 6ft, half inch round-up isn't that great a deal for most people. A chunk of the day you will be near 6ft anyway. ]

R. Oli said on 1/Sep/15
Hey Rob I've viewed this site for a little and I've recently had a problem. I measured myself at a little over 6'1 yesterday morning, but now I'm 5'11.5. I'm only 15 and I'm pretty sure I'm going through a growth spurt. Is it possible to shrink 1.5 inches in a few days without proper sleep or something? I had home work to do and stayed up until 1 am due to assignments and I had to get up at 6. Yesterday I went from 6'1 to 6'0 yesterday now today I went from 6'0.5 to 5'11.5. What's going on?
[Editor Rob: you might shrink just over an inch from out of bed to night, but maybe you got 5ft 11.5 at your absolute lowest mark. I wouldn't measure too often, just every once in a while. I think people can end up measuring too often and then worrying about not growing.]
Anon* said on 29/Aug/15
Hi Rob. Do you think exercises like pull ups are good for fighting height loss as we age? I feel it helps my posture, back and core muscles in general. Also, I've read that you don't think heavy lifting is good for the spine; Is 100kg squat/deadlift too much pressure on the spine once every week or so? Not that I've reached that squat target yet!
[Editor Rob: if you are doing heavy lifting for years, it can raise the risk of longer-term problems, but occasional heavy lifting might not have as much impact. Certain lifts involving bending of the spine are the ones that could cause excess pressure and over time cause disc damage. The problem can be sometimes one disc that has issues could have a cascade effect and other discs end up with issues. If you do lifting, I'd incorporate some bar work and hanging as well with helping decompress the spine. Also chin/pull-ups and some other core (knee raises or leg raises) exercises on a bar are the kind of basics I've been telling people and what I'm doing myself. ]

Guy said on 26/Aug/15
How quickly does height start dropping once someone has risen from bed? I am 6'1.75" or sometimes a bit more immediately out of bed and 6'1.5" only about 20 minutes later. Conversely, by late afternoon I'm around 6'1.35" and then it takes several hours for me to drop to about 6'1" even right before bed. Is a loss of a quarter inch in 20 minutes normal and does the loss tend to be most dramatic in the morning?
[Editor Rob: it's quite normal to lose a big fraction within the first hour of being out of bed.]
fred said on 24/Aug/15
by the time I go to the doctor's office which is afternoon usually I have lost an inch or 3/4 of an inch at least..throughout the whole day from morning to night I have lost about 1 1/2
[Editor Rob: that's a lot of height to lose. I'd expect somebody very tall to lose over 1.25 inches, but an average height man losing over 1 isn't as common.]
Anton said on 4/Aug/15
Hey Rob, I'm really very interested by an answer here please. With this picture : Click Here How tall do you think the guy next to Bill Clinton is? Thanks for the answer Rob!

Simon said on 4/Aug/15
Rob, how much height is lost by age 58...on average?
[Editor Rob: a quarter or 1/3rd of an inch for a man might be normally expected by that age, for a women maybe 3/4 an inch]
Tan said on 2/Aug/15
If you are in a car all day for a long trip will that make you shrink to your low ? Thanks for your time
[Editor Rob: that can increase the pressure on your spine and make you hit your lowest height quicker.]
Jake said on 20/Jul/15
Hi Rob, I measure 188cm first thing in the morning and come to 186cm before I go to bed after a typically long day involving 15-20km of walking and many hours of standing with most of the shrinking during the initial stages of the day. I'm 19 years old, is this daily height loss typical given the situation? And should I claim 6'1 or 6'2? I think 2cm can be pretty noticeable.
[Editor Rob: if you went with cm, personally I'd say 186cm because nobody is really going to think you aren't that height. 2cm shrinkage is very typical.]
Manjit singh said on 16/Jul/15
Yes, indian superstar stated in a movie that he was 6'2", but that was during his late 40s. Everybody has an opinion that he was atleast 6'3" in his prime. Now he is 72 years old, i think he is below 6'2" now, but nobody being 6'2" can look that way as he looked in between 1970 and 1985, he was definitely 6'3" in his prime.
Boris said on 23/Jun/15
Thanks Rob. I only seem to dip below 5'8" on certain days, particularly after lifting weights at the gym (yesterday I did back, measured at first right around 5'8" at around 7pm after the gym, but then it seemed to dip to like 5'7.9", then back up to like 5'8.1" later after sitting for a few minutes). Weird. I guess I consider myself a very slightly weak 5'8" at worst. One more question as far as the measurement method. I do the aerosol can method, and I get different results depending on if I'm facing the wall or back to the wall. The only time I seem to get similar results is, when I'm facing the wall, I press my face against the wall as much as I can (because if I look straight forward, the highest part of my head is the back of my head). If I don't do this, I measure a bit shorter when facing the wall. Does this sound correct? I notice in your videos you just seem to have your nose touching the wall, but I have to press in more (scrunching my nose a bit) to have the aerosol can hit the top of the back of my head.
[Editor Rob: if the can is long like 10-12 inches then there's no problem, but if 7-8 inches there is always a chance it might not hit the highest point. You can use a video tape (or really the cassette tape case), but that's in the 7 inch range so you really need your nose touching the wall to ensure you hit the highest point of your head.]

Hey Rob! Question for you. My morning right-out-of-bed height is anywhere between 5'8.75" and 5'9" ish (depending on how many hours I've slept). At night, depending on the day and how active I was, I tend to shrink down to anywhere between 5'7.9" and 5'8.25" (but usually around 5'8.125"). I've noticed that even if I shrink down to a tad below 5'8" (after being active/the gym/walking a lot), if I sit for a bit, it climbs back up to up to 5'8.25". I usually just say I'm 5'8" when I'm asked. Do I sound like a strong/legit 5'8'? My "resting height" seems to be just over it regardless of the time of day, so I feel it's ok to go with that.
[Editor Rob: I'd say you were a decent 5ft 8 because the vast majority of time you would hold the mark or be a little above.]

Hello Rob! How's it going? Could you please create pages for:

Sam Underwood : Click Here
Brando Eaton : Click Here
Lucas Adams : Click Here

These are all young actors appearing on Dexter and I'm very interested in knowing how tall they are. If you don't want to create a page for them, could you please at least tell me an estimation on how tall do you think they are?

Thank you very much, bye!

HI ROB I have a question. I am still growing and I am about 6'1 and some change at the end of the day and in the morning I am 6'2" on the nose. could I use 6'2" as my current height without lying or no.
[Editor Rob: I'd just say 'over 6ft 1' just now...you may well end up taller]
Rick said on 30/May/15
Hi Rob, I'm 21 years old and very worried about the effect of bodybuilding on height loss. What do you consider "extreme"? Cuz I'm not a powerlifter, I just do amateur bodybuilding. Are there exercises one should avoid like squats or deadlift? Thank you!
[Editor Rob: loading weights isn't bad for you, it's the extreme and long-term effects that might cause problems. Actual lifting moderate weights can be beneficial, as you know for your physique and strength and actually as part of an overall bone health. It's when you go to very big weights and long-term it can start to cause problems with discs... This is from an abstract of a paper which studied discs in various people and athletes: "When comparing lumbar magnetic resonance images of 24 runners, 26 soccer players, 19 weight lifters, and 25 shooters, disc degeneration and bulging were most common among weight lifters; soccer players had similar changes in the L4-S1 discs" "Maximal weight lifting was associated with greater degeneration throughout the entire lumbar spine, and soccer with degeneration in the lower lumbar region. No signs of accelerated disc degeneration were found in competitive runners"]
Johemoth the dog said on 25/May/15
Hey Rob, im about 5'9 1/2 or 3/4 somewhere around there, and i was wondering if its possible at 17 to grow even 1/4 of an inch? I know its pathetic to be crying about 1/4 of an inch but some reason i want to be 5'10, i am about 5'10 1/4 in the morning. I can give you some idea of my growth, I know at 14 years old I was 5'8 1/4. and at 15 or 16 i was my current height. Thanks
[Editor Rob: at 17 there is still hope. First thing I'd do is forget about measuring and just enjoy life. Reduce too many stresses in the body. Then, start doing maybe more exercise (circuit type training or sprints) - high intensity that gets Growth Hormone production going...add in some stretching for flexibility and of course as mentioned many times - the body needs the time to grow, so make sure you are getting enough sleep for repair and recovery.]
Boris said on 19/May/15
Rob, does working out at the gym/lifting weights make you shorter? I have read conflicting things on this. Are there any particular exercises that we should try to avoid to not lose height? I love working out at the gym, but I'm about 5'8" now (I measure about 172.5 at night barefoot after being up for a while and walking around) and don't want to lose anymore.
[Editor Rob: long-term heavy lifting could damage some discs and contribute to quicker loss of height. Any disc damage could result in a fraction of height lost. If you follow proper form and don't overdo things you may be ok... The actual act of lifting weights will make you shrink to your low height faster because of the excessive forces on the discs. After you rest for a bit though your spine would recover.]
Kenny said on 12/May/15
Hi Rob is it normal to shrink an entire inch through the day at my age and height. I just turned 16 recently and I measured myself at the morning/out of bed using the aerosol can method and I got exactly 5'10 and I measured again at around 10.30PM and I got exactly 5'9.
[Editor Rob: yes,when you are young your discs are able to rehydrate/absorb more water content than when you are older so your morning/evening variation will be more when 16-20's compared to in 50's or 60's.]
Sean5 said on 10/May/15
Hiya Rob I was wondering if after 5.5 hours out of bed I do 1.5 hours of normal cycling,1.5 hours of walking, and 2.5 hours of sitting down on the computer then measured would it be a fair measurement?
[Editor Rob: you likely would be at your low height yes. If you measured straight after a cycle ride like 1.5 hours you might find you were a couple mm lower than if you got home and sat for 2.5 hours at the computer, then measured.]
Mc51295 said on 5/May/15
Rob, I'm 5'7.5 in the morning and 5'7 at night. At 20 years old, is that a normal height loss over the course of the day?
[Editor Rob: it's within kind of range...0.5-1 inch covers a lot with about 0.75 inch being quite a common daily shrinkage.]
RB said on 26/Apr/15
hi rob want to ask you a question when you call somebody a solid height does it mean they never dip below that mark whenever they are measured?
[Editor Rob: yeah pretty much they are unlikely to dip under the mark, and if they did it might be a tiny amount 1-2mm or so. A weak 6ft might dip 1/3rd under it...but a portion of the day (before lunch) they still would measure 6ft. The solid 6ft guy might be 6ft 0.25 range at 11am and maybe at 6pm is down to 6ft flat.]

DrStrangelove said on 9/Apr/15
Hey Rob! If i'm 169.3 cm in the morning and 167.3 cm at my lowest during night time. Would it be correct to consider myself 5'6?
[Editor Rob: 5ft 6 is right in the middle of your morning/evening, so some people would take the middle. Others even go with morning, while a fair chunk go with evening height. I think you are ok to say about 5ft 6.]
al said on 8/Apr/15
Rob I'm about 182 cm do you think I'll get to 183? I'm 16 y/o
[Editor Rob: you have a good chance.]
Rusty 190cm said on 6/Apr/15
And rob do you think at 50 I will have lost quarter inch?
[Editor Rob: the average at 50 isn't much like 5-6mm really.]
Rusty 190cm said on 6/Apr/15
But Rob do you think 6'2.5" at 55 and maybe 6'2.25" at 60 is what I could expect? You said 1/4-1/2 range is expected by 55 so if I lost 3/8 of an inch by then I'd be 6'2.5"?
[Editor Rob: yes you'd still likely be that range. Sometimes we can't really prevent loss because our discs suffer age related degeneration. But, if you are doing regular activites and exercise, making sure your meals cover a lot of the vitamins and minerals our bodies need, that might help slow/reduce height loss compared to average people. There are those who barely shrink by 70 - my own Dad did well to about early 60's - his job involved curtains so he was fitting a lot of them and maybe more active in 50's, but from about age 62-70 is when he dropped from almost 5ft 10 to 5ft 9. He retired, and lack of exercise and more sedentary lifestyle didn't help.]
Rusty 190cm said on 2/Apr/15
Rob if I'm 1/8th inch shy of 6'3" at age 23 do you think I will likely be 6'2.5" at 55, 6'2.25" or so at 60 and maybe 6'1.75" at 70?
[Editor Rob: if you are 6ft 2 at 70 you should be delighted... about 1.25-1.5 loss for 6ft 2-3 men by 70 is more typical. 0.5-0.75 loss would be more typical for 5ft 2-4 range men!]
AaA said on 16/Mar/15
Hi Rob, i'm 15 and 5'10''. My parents tell me not to worry but i'm never comfortable with my height.I think I have OCD because i always think about height.
[Editor Rob: I think most people suffer from varying degrees of worry and more intense periods of anxiety during life. It will manifest itself in different forms, for some it will be their height, but all for others it could be their hair, nose, legs etc...it can be hard to control them, sometimes for people it is trying to live with them. I always say if you fill your days with more activities, fun things or educational stuff then there is less time to worry about those things. You are already 2 inches taller than me and you stand at right on the average...you may even still gain another 2 inches! Maybe with time you will learn to cope better - think, you are taller than well over a billion other men on earth!]
MG said on 11/Mar/15
Hi Rob, I'm a 6ft tall woman and I would like to shrink by 1 or 2 inches. Is it possible ?
[Editor Rob: I would try to work on your confidence - many men, let alone women would love to be 6ft. To lose height, well posture is one way, wearing thin footwear is another, but I don't recommend altering posture because over time it might damage your spine and make old age more uncomfortable.]
Helpplease:( said on 8/Mar/15
Rob I am 5'7 and when I wear very tight t-shirt I feel so small (well I get fat for the few months and it makes my t-shirt x-small). and I stand to a 5'3 person I think that I am just the same height or I am only a little bit shorter.. help rob please.. is it NORMAL?
[Editor Rob: you are maybe just quite thin for your age, maybe with some more years your body will fill out a little.]
:) said on 23/Feb/15
Rob, I am around 5'5 and my dad is now around 5'1. But I saw a photo of jim next to a 6'2 guy and he looked 5 inches shorter making him 5'9 back in 2005. He is now 53.. Why has he lose so much height in just 10 years?
[Editor Rob: maybe he's not lost that much, but the other guy wasn't standing as tall as he could have.]
James Edward Crowley said on 10/Feb/15
Rob do you think you will still be 5ft 8in until your 88 that means your will be a late bloomer in terms of height loss is it possible not too lose until your late 80s early 90s like 87 88 89 90 and 91 i bet you will be happy if you can stay a strong 5ft 8in for 50 years maybe even 53 years and not drop a fraction or a inch.
[Editor Rob: I think it would be impossible to reach that age without height loss. The natural ageing process means your discs will degrade and not hold as much water content as they did when younger...but there may be some lifestyle changes or simple exercises that if you keep doing them then you can reduce the height loss. I will certainly be keeping up a simple routine - assuming I'm still around over the age of 70. It will be interesting for me to see when I start to lose height though...]
Rusty 190cm said on 1/Feb/15
Rob, my question was how tall do you think I will be at 55? Is 6'2.5" most likely?
[Editor Rob: you could by 1/4 or even 1/2 inch less at that age...or be lucky and not lose anything. Can depend on factors in your 40's like activity, whether you do exercise etc.]
Magic said on 30/Jan/15
I now lift 4 kg for each arm, max will lift 10kg for each arm is it too much?
[Editor Rob: that's not too bad, it's certainly nothing extreme!]
Magic said on 30/Jan/15
Rob, bodybuilding with weight reduce stature, i.e. height loss?
[Editor Rob: big weights over prolonged lengths of time (years) could definitely do some damage. Discs put under sever pressure might start to wear out or get damaged. I personally wouldn't lift big weights, but moderate weights can help strengthen your back and core without doing as much damage as lifting too much weight.]
Rusty 190cm said on 30/Jan/15
Rob I am just a smidge (1/8-1/16th inch) under the 6'3" mark after being awake 12 hours. If this is the case how tall do you think I will be at 55? 6'2.5". I'm 23 currently. Also, what would your advice be for me to minimize height loss as I get older? I walk with excellent and impeccable posture but haven't been as good at getting regular exercise since I work a desk job like you do.
[Editor Rob: I will do a quick video sometime soon talking about this and give my advice, that I will be following and have done for a few years now.]
Magic said on 26/Jan/15
Is possible to lose height with bodybuilding?I lift weight and squat, my weights are lightweight , 4kg now for each arm , but they could became more, up to 10kg.When I lift weight feel compress spine, or however a weight on it.
I am already short(around 5'5") if I lose also only 1 cm would go in deep depression, because the girls wanna the boy tall and these girls are also shallow and compare we (short men) with highheels. E.g. I like a girl of 5'3" but she wouldn't want me because with 3"-4" inches would be 5'6"-5'7", ok I with shoes would be around 5'6".Now also girls short wanna tall men 5'7" is lower limit.No everywoman think so, but it is so statistically!Women taller than me, they afraid a bit me, but no too much, but here in Italy is hard to see a woman taller than a man as couple, so...THAT PROBLEM for us short men!However, return at the question, bodybuild make to become us shorter?
KawaiiKitten154 said on 7/Jan/15
Is there a way to lose height without any surgery, and safely? Because I am 4'10, but I am not done growing because I under the age of 17-18 and under 13 years old, so I don't know about any safe way to lose around 4-5 inches without a dangerous way
[Editor Rob: lose height, do you mean gain height? At 4ft 10 I'd assume you want to increase height...all I can keep saying is that if you give your body the fuel, give it the rest, and shock it a bit with enough exercise (to help with growth hormone production) then you are doing your best to maximise whatever height you can.]
Alex said on 21/Dec/14
So what do you think it is Rob? It seems to be more of a 1-0.8cm loss as I'm near 173cm.
[Editor Rob: I really wouldn't expect such a loss within a year unless an injury happened or bad floor/wall contributed to a mismeasurement. I suppose the other thing could be the ability to stand as tall might be a cause for a cm difference...]
Alex said on 19/Dec/14
Hi Rob, love the site Is it possible to lose about 1-2cm in height from poor posture in your early twenties? I measure at my lowest (near 20 hours awake) and last year I was 174-173.8cm, this year I am about 172.7-172.3cm at my lowest. I'm definite I measured correctly and I assume I stood as straight as I could both times, but that said I always slouch when at the desk unfortunately. Is it possible to regain height or can it perhaps be disk damage? Is it even possible to notice bad posture when trying to stand straight? My diet is pretty poor too, I'm not sure if that played a part. Thanks Rob!
[Editor Rob: if you are measuring the same place/position etc and are getting a cm or even 2 different it's a head scratcher. You can develop bad posture, but it's over years...injuries to your discs can certainly cause a bit of loss, but it seems a big difference! I've spent years hunched over typing etc, my posture should be worse, but I do basic exercise to limit any shrinking, I've yet to lose a mm at age 38 and I've been 20 years computing really at desks.]
MJB said on 28/Oct/14
hey rob! last january i was 184 centimeters as measured by the doctor but now as of october i was measured at 181 centimeters by the doctor. Rob, is it possible that i could of injured my back and not know it? plus Bruce Willis is 6ft like i was. please respond with your opinion about this.
[Editor Rob: I'd say this is probably a mismeasurement or wrong reading noted by the Doctor.]
Kendalljennergreatestfan said on 21/Oct/14
Rob, would you say it is more accurate give people our morning height or night height?Thanks in advance for your answer.
[Editor Rob: I think if you go with an average of when people get measured, that is fine...so I'd rule out the morning height since only a smaller percentage of people ever actually measure out of bed.]
sharmila said on 20/Oct/14
iwas 153 cms at the age of 23 when i was selected to government job it is proved in my medicals. But after nearly 23 years again for promotion purpose they referred me to same hospital which i was earlier referred to my surprise,now i was measured only 150 cms which is 2 cms short to be selected for my promotion in govt. service please let me know chance of happening like this? since i going to take this issue legally.
Kendalljennergreatestfan said on 18/Oct/14
Rob,can people get more than an inch shorter during the day? And it is true that if you are the taller you get shorter than someone smaller?Thanks in advance.
[Editor Rob: some really tall people will shrink 1.5 or maybe even up to 2, but this is people with really long spines. Generally if you are under 6ft you won't shrink 1.5 inches, although a good chunk of people might still lose a full inch or so. I think it will work roughly in proportion, the taller you are the more chance you lose more.]
cd said on 28/Sep/14
Hey Rob sorry for all the questions lately but I have another one lol. I decided to measure everyone in my family again including my dad who I had measured last year at about 173cm in the evening. This time I made absolutely sure it was a fair measurement, it's hard mostly because my dad isn't someone who likes the idea of being measured because it "serves no useful purpose". Or maybe he just doesn't like the idea of having lost height or not being a 5ft 9er which is what he used to claim to be ;) Anyway, this time he had been up for about 3 hours, using the aerosol can method I made sure he was standing tall but not heaving his spine up, and that his head was neither tilted up or down. The tape measure said exactly 68 inches. So if he is 5ft 8 after being up for 3 hours what could he shrink to by evening? Also how much may he have lost by age 55?
[Editor Rob: at 55 really you could shrink from 0 up to an inch, but on average I really wouldn't expect more than between 1/4 and 1/2 range. Today he might drop to 5ft 7.75. For women, shrinkage can definitely happen by mid 40's, I am seeing this with Jenny who has shipped a 1/4 inch by that age! Although I have given her basic techniques to help her spine, getting her to do them is another matter if she wants to slow down loss.]
Magic said on 14/Sep/14
Hi Rob, my father say that was 5'6 when he did the military service,but today he(is 54 years old) and he is as tall as me or maybe a bit more,he should be 5'4 1/2(164)- 5'5(165-166),rather in many photos ara taller than him. Is it possible that in military service had wrong to measure him?2-4 cm seem to me too many. PS:noone doctor has never measured me,maybe to 13 years old and if I remember well said 166 cm(thing strange maybe he measured me with shoes) or 164 cm I don't remember well well.I'm measured barefoot,compressing the hair and signed a point on the wall,I should be 5'5(166 bed out,165 in the morning)almost 5'5 (164,5 12 am 13 pm),5'4 1/2 ( i belive 163,5-164 evening).
[Editor Rob: 1 inch loss at 54 is more than you would expect. Although it isn't impossible, maybe your Father got measured in shoes, or really was more 5ft 5-5.5 than 5ft 6.]
Lucia said on 26/Aug/14
Hi Rob, I am 31 and after probably 10 years of not measuring myself I have found out that I am 3-4 cm shorter!! Is it possible?? I am really horrified! I have always been short 157 cm so to find out that I actually measure 153,5cm is really shocking. I think I am also slouching. Could I gain some centimeters by straightening ? Or is it too late? Thanx
[Editor Rob: that sounds surprising. Maybe there is a difference in the way you were measured before and now. It's too much to actually lose at 31, I suspect it is either a wonky wall/floor giving a bad measurement or maybe you just can't stand as tall! In that case, some simply back stretches (things like reaching for the stars) might help.]
Dan 176cm said on 23/Aug/14
Is it possible to naturally lose height before 30, Rob? Can it be accelerated due to poor habits? I remember being measured at 177 cm afternoon height when I was 19 (22 now) and I can only achieve 177 early morning now. There's a lot of tension in my neck though, and I feel like maybe hunching over the computer has led to some decreased height?
[Editor Rob: I don't know. I've spent 2 decades doing computer work although I have done regular breaks and not spent 10 hours a day sitting hunched over. I would be surprised under 30 to notice any height loss, but it is possible that poorer posture might mean for a measurement not being able to stand quite as military as you could aged 18-20?]
Adam said on 16/Aug/14
Rob, is it possible for me to stay at my current height 172 cm till age 80?
[Editor Rob: very hard to do so - unfortunately our discs will suffer aging and so thin to some extent, but if you maintain good health, eat well so your body has all the nutrients as you age and keep supple you might be able to 'beat' the average and not shrink as much. Posture as you age can be a bad habit that leads to spinal/disc problems over a long period.]
DMEYER said on 1/Jul/14
rob 1cm loss by 50 2cm by 60 3cm by 70 is pretty average 5cm by 80
[Editor Rob: I would be happy with this: 0.5cm by 50, 1cm by 60, 2cm by 70 :) If that happened I'd still be 171cm at 70 which would be ok. If I live that long and still doing this site it would be interesting, but I hope to still do it by age 50 so I can still be 5ft 8 for many meetings with celebrities.]
J.Lee said on 6/Jun/14
Rob, what I found helps posture and height maintenance is not just back exercises, but abdominal exercises. I find that any core exercise will play a role in maintaining your posture.
Seahawksfan 187-188 CM said on 7/May/14
How often could bending down decrease height? I try to follow it up by standing up tall right after, but I notice that it's hard on my back right after slouching and that my measurements decrease in the short term. Whenever I go a certain amount of days without slouching an insane amount, I notice my height slowly going up until I slouch again.
[Editor Rob: never really experienced that...only time is sometimes with a pulled back muscle my posture has been effected and maybe I felt smaller than before, probably because I wasn't holding myself properly to compensate for the pain.]
Maio said on 3/Apr/14
rob, a person who lives near me is 80 years old. He has a scolyosis problem and has a very bad posture. With his normal posture he looks close between 5ft7 and 5ft8 but if he stays straight he could be around 5ft9...perhaps 176 cm. I claimed that in during his youth he was 182 cm. I doubt it a bit because i saw pics where he was with a couple of people who i met and i think he was around 5ft11. Possible someone with scolyosis lose 6/7 cm or it's more probable he claimed a morning height? Considering i don't think he ever measured himself...
[Editor Rob: 5ft 11 certainly could be possible, how much the scoliosis effected his height over the years is harder to pinpoint]
aceofbase said on 30/Mar/14
any guides that show how to avoid height loss?
[Editor Rob: I don't know about guides but my own thoughts are... don't do heavy lifting. try to do 5 minutes every other day even of basic stretching, practicing also to hold a better posture if you find yourself slouching. As you age, lack of strong muscles can then contribute to poorer stance/posture and bad habits, which can lead to disc problems. keep ensuring you are getting a good diet with enough minerals like calcium/magnesium etc.]
Bud said on 6/Mar/14
Rob,do you know what made Arnold Schwartzenneger,Clint Eastwood,Lou Ferringo and David Prowse to loose so much height?For there age they lost a lot,Prowse even lost height in his early 40s,how is that possible?
[Editor Rob: sometimes excess amount of lifting over time can lead to disc damage, maybe in those guys cases they were more prone to it?]
