Height Loss

Whilst celebrities have access to everything money can buy, unfortunately, like us mere mortals, they can succumb to the rigours of ageing, 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 ageing, 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 Ageing, 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), osteoporosis 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 3.5 to under 6ft), Hulk Hogan (6ft 6 to 6ft 3), Dave Prowse (6ft 6 to barely over 6ft), Sylvester McCoy (Almost 5ft 6 to 5ft 2), 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 is it normal to not lose all the range you lose usually when you are working, walking or when you're active, in days which you are very sedentary I tend to drop to low height only when I'm at least active, at least when I walking a bit... even if it's not maybe the true low but on the mid/low range.

When I'm sedentary sitting the whole day on computer I tend to lose only 1 cm... when I'm sedentary but a bit active I lose 1.5 cm... when I'm very active I lose 2-2.5 cm

On a lazy day when I just sit on computer If I'm 185.4 cm out of bed, 185 cm 1 hour after bed, 184.4 cm 8 hours after bed on a lazy day and my lowest on a relax day when I just sitting at computer is 184 cm after 15 hours awake out of bed...

But when I do some walking, when I work a little bit and when I'm active I tend to shrink in 4 hours to low height of 183.9 cm, and after many hours awake being a bit active with same activities for longer time I'm 183.5-183.6 cm. Sometimes I reach the extreme low after 20 hours out of bed and after intense activities extreme low range of 183.3 cm

Should I claim 183 or 184 as actual height?
Editor Rob
I do find when I'm active and maybe doing more work I get down to low range, but some days maybe hold 1/8th above my low if it's a more sedentary day.

You could claim 184, that seems reasonable enough.

Hey Rob! Love the website.

Can we use nighttime measurements to estimate a legitimate height claim? I never know what to claim and sometimes it makes me curious as to what I should say to avoid "inflation". Many people have been privy to label me 5'8, yet I always felt shorter than the legit 5'8s I know.

I've been up for 19 hours now, am relatively dehydrated, and spent lots of the day carrying a 20 pound backpack on my back as well as tugging a 30 pound suitcase across many kilometers. I just measured myself now in the 19th hour of being up and I'm 169.5 cm tall, using the back against the wall + can against head method. Would 5'7 be a legitimate claim or am I closer to 5'6.5? I feel 5'7 is solid since I was under lots of stress today, and last time I went to the doctor he had me pegged at 171. I don't want to inflate my height but I don't want to sell myself shorter than I am either.

I'd love to hear your input. I'm taller than every 5'6 claiming guy I've ever met, and I don't know who they're fooling. Trying to inflate your height is useless, everyone is the wiser (except when it comes to themselves, apparently)!

Funny story, where I live you have to stand in front of a mugshot wall barefoot when taking the picture for your driver's license, because they list your height on the licenses! I got it young at 16 and the lady said I'd "grow more" in the next years and she put 170 cm on my license instead of the 165 I was at the time. She was pretty accurate with her guess!
Editor Rob
You're in the almost 5ft 7 category I'd say...if you claim it, then it's a fraction round up...considering 169.5 might be a real low range for you and some days at lunch you could be 170cm range.
Ben said on 16/Aug/19
Only 5-6mm Rob? Back in february when I was measured for my passport at the police station I was 180cm after 2 hours out of bed but in may when I was measured by the army I was 178.7cm after 6.5 hours out of bed. To be fair I had done pretty much nothing in those 2 hours just relaxing except when I got ready and sat in a car for 45min...while in those 6.5 hours I had done a lot of activities from 5am to 11:30isch am.

Hamadd823 said on 16/Jun/19
Rob, what is the average loss in mm between a 2 hour out of bed measurement and a 6 hour?

Editor Rob: could be 5-6mm
Editor Rob
Based on the average, about 5-6mm between that timeframe is what I would expect, though activities (or lack of) and your overall shrinkage might mean a bit more.
khalil55 said on 15/Aug/19
Hey rob, i stand 176 cm in the morning after bed and i fall to 173,7 in the evening. What height should i claim ?
Editor Rob
174 is a comfortable claim...but say you went to the Nurse at 11am? You could be nearer 175 than 4, so it's understandable why claiming 175 is a possibility too.

But I would go with what you feel comfortable saying...the main thing is you wouldn't be claiming a false height or an 'in shoe height'. Half the population are inflating their heights an inch or so.
MisterShort said on 14/Aug/19
I've lost half an inch the last year and I am 30 years old. Any idea why this could be? I have stopped working out at the gym (only used to lift weights) for the past year but I also have some back pain and wonder if it is disk degeneration. My posture appears to be unaffected.
Editor Rob
It's strange to lose half inch at 30...either posture has become worse or maybe some disc damage has caused it.
AlexM said on 11/Aug/19
Rob, I get out of bed 172.6, evening minimum 170.8. Can I call myself 5ft7.5 (171.5)?
Editor Rob
If you say 5ft 7.5 to people, it's fair enough I think.
Daycringeothon said on 8/Aug/19
A guy as physically big as Arnold Schwarzenegger was in his prime body building years. Let’s say 184cm-185cm most of the day. On a good day a morning height 187cm in his late 20’s-30’s. Even prior to his surgeries
at ages 50+ he shrunk to 183cm late in the day as a low. Having good proportions for his height and as a large built man it would be expected for up to 3 cm height loss in a day. Now add an inch of loss due to age. He would look shorter from a distance yes. Taking into account his large build then seen closeup that changes the perspective to actually looking 5’11”-6’.
Emil123456 said on 3/Aug/19
Hey, I’m almost 184 cm out of bed, and about 181,7-182 cm just before bed. What should I claim? and does that make me a weak 6ft? Have a nice day
Editor Rob
Yeah a weak 6ft range is what you fall into...or a strong 5ft 11.5 range.

You could always go with about/almost 6ft.
Micheal2822re said on 1/Aug/19
Hey rob
If I measure 179.4cm in the morning and the night 177cm
Is it okay if I claim 5ft 10.5
Editor Rob
That's your morning height...many folk claim that, though I personally don't.
Adis said on 30/Jul/19
Hey Rob is it possible to grow after 18? I learned in high school that males can grow to 21. I was measured at 185cm at noon. My father is 182 right now but he is 51, probably around my height when younger. My mother is 47 and she is currently about 177cm.
Editor Rob
Yes, a percentage still gain height to 21, but the majority don't gain anything after turning 18.
Arthas said on 30/Jul/19
Hi Rob if on a lazy day (only sitting at computer, sedentary) I am 185,2 cm at morning on a lazy day 20 minutes after sleep, 184.6 cm 3 hours after bed, 184.2 cm 7-8 hours out of bed, then at the end of the day at night I'm 183.6 cm... but that's on the lazy day.

In a working day (walking, play soccer) I'm 184.4 cm 3 hours after bed, 184 cm exactly 6 hours after wake up (before lunch at 2 pm), and 183.3 cm at night at 9-10 pm... my extreme low in an active day it's 182.9 cm

So overall what height should I claim? 183 or 184, or 185?
Editor Rob
Claiming 184 might be a good compromise...what's important is you are actually giving a figure which you measure and will look to most people.

Half the population are giving heights 1-5cm more than they actually measure out of bed!
Jetsfan35 said on 29/Jul/19
Hey Rob i've been taking glucosamine pills for 8 months now because of my joint pain. I only found out a week or so ago that glucosamine has the ability to make you 2-4mm taller and when i measured myself i've noticed that my morning height went from 174.3cm to 175.1cm and my low from 172.5cm to 173.3cm, from 8 months ago I'm 27. My question is that do you think these marginal gains are permanent? or if i stop taking glucosamine i will shrink down again?
Editor Rob
I would keep taking them if they seem to have helped your joints and height by several mm!
ablue said on 27/Jul/19
Hi Rob,
I currently stand at 172.2 cm in the morning. After spending much of the day sitting, I’m about 169.8 cm (this is a little over 12 hours after waking). I know that 170.18 cm is the equivalent of 5’7, so my main question is whether I should consider myself that height of 5’7. Additionally, how would this height compare to the majority of people who claim to be 5’7?
Editor Rob
Yes you can safely call yourself 5ft 7
criss83 said on 24/Jul/19
Rob,
The listings on your site are average listings, mid day, the lowest?
Editor Rob
Think more lunchtime than morning!
Steve Warren said on 23/Jul/19
Hey, I’m 177.7cm tall out of bed, and 176.5cm throughout the day. So do you think I could get away with claiming to be 5’ 10”?
Editor Rob
To most people you will look half inch shorter than 5ft 10...to those who actually pay attention and can tell such differences.

The majority of people aren't going to be that observant, so saying 5ft 10 wouldn't raise many suspicions!

If it were me, I would personally claim 5ft 9 and a half.
182cmcmm said on 22/Jul/19
Hey Rob,
I got a question I'm 183.4 out of bed and 182 before sleeping. During 12 hours day I'm working sitting and using computer and I'm walking for like 2 hours. So my question is if we losing same amount of height while we sit straight as we walk.
Editor Rob
On some couches, the spine might not be under as much strain as sitting at a desk. If you have an office type job, there is still a fair amount of pressure on discs. I doubt you shrink much further based on your night height of 182.

Maybe 2-3mm more on a long day doing outdoor work.
growing said on 20/Jul/19
Is growing possible after 24? My mom is 170 and my dad 175, I'm 179 in the morning and 177 at night
Editor Rob
Very very few people grow past 21-22...though not improbable, I'd say the odds were small.
Dezmond said on 14/Jul/19
Hi rob, With my back against the wall I’m 6 ft 1.5 but facing the wall I’m 6 ft 3 I met some people who are 6 ft 1 and I was noticeably taller I think my eye level is 5 ft 10.5 I’m standing straight as possible against the wall btw
Editor Rob
Maybe you are finding it harder to stand and measure with back against, or are bending your back?
Simon Rickman said on 13/Jul/19
If I’m 180.5-181 cm out of bed and 178.5 before going to sleep what should i claim?
Editor Rob
If I were in your situation, I might be going with 179cm
Hussein said on 11/Jul/19
Hi rob, does swimming like 4 hours can shrink to my low? If it is 167.8 can i go with 168 as my height? Also 10 hours after bed
Editor Rob
It's going to get you to your low if you do a fair amount of swimming, because even though there's less resistance, you are still using a fair amount of twisting motions in your spine.
PaulSP said on 10/Jul/19
Hi Rob, I’m 186cm at my tallest and usually around 184,5cm at my lowest, so I claim 6’ 3/4”. Would it be reasonable for me to claim my metric height as 185cm, as opposed to 184?
Editor Rob
Yeah, it's reasonable to go with 185cm
Dmeyer said on 7/Jul/19
Actualy today i was 183,2cm 20mn out of bed so probably easy 183,6cm right out , so still close to Peak morning height , facing wall IS much easyer to stand fully tall
Editor Rob
Yes, you are less likely to have the can slip or bend your back (and thus not stand as tall).
Lildumars said on 6/Jul/19
Hey Rob at the morning I measure an exact 177 cm but today after walking home from spine loading exercises such as deadlift and squats for 2+ hours at the gym I measured at 174.5. Is such drastic height loss possible...is this okay? I’m a little concerned because it seems like a lot of height lost.
Editor Rob
You could have hit your low height...it's not an extraordinary amount to lose...
criss said on 5/Jul/19
Rob, I'm 183 in the morning and 181 at my lowest. Sometimes I'm 181.5 at lowest or even 182 if I'm rested.
Claiming 182 it's not bad, isn't it?
Editor Rob
It's fair to go with middle value - one thing is certain, at least it's not a false height. Many folk with your stats will give 184-5, many 183 too, but a smaller percentage (compared to those claiming 182,183 and above) would only go with 181 low height.
Dmeyer said on 5/Jul/19
Rob my max morning height is 181.3 and my lowest is 177.8 is that a lot of height to lose..also two years ago my max was 181 and low 177.5 do you think I grew in that period
Editor Rob
It is a lot, but sometimes when we are younger our discs are at their best health and can absorb more water. Wow that IS huge 3,3cm loss at under 6'0
Dmeyer said on 5/Jul/19
Hi rob , its likely to loose 2mm of morning height by late 30s early 40s for example back to wall After a good sleep i use to be back to wall 183.6 ish lately i think i am nearer 183,4-183,5cm , yet at night i am still similar range 181,2-181,5cm depennding , facing wall i am 1-2mm taller as i alter my spine less , today i was 182,8-182,9cm 30 min Out of bed of course i could have droped 6-7cm within 30mn i will check next Time a mn out of bed ,many people will measure 10mn out of bed so they droped alreasy 2-3mm and then measure 3pm on a normal day then the différence will be just 1,5cm but if they measure out of bed and then 7pm on theyr feet all day the différence will be nearer 2,2cm and near 3cm if they are 6'2 or more
Editor Rob
Yes you could lose a tiny amount like that. There is a definite difference of a few mm even with 10-15 minutes out of bed compared to 30 seconds out of bed.
Kiers1996 said on 2/Jul/19
Hey Rob first thing out of bed I'm exactly half a mm under 175cm. I think you and me could be height twins because right before bed I got a low of 172.9cm. I never feel tall but then I dont feel short unless theres a 6ft7 guy in the room then I feel towered lol.
Editor Rob
Yeah those stats are very close to mine. IN the UK, 173cm feels lower average range - when they say UK average is somewhere around 5ft 9 zone, I believe it.
Martin Novak said on 1/Jul/19
Hi Rob, I´m 199cm and I would like to be smaller. Is possible to decrease my height at least 3cm? Is there something what can I do? I´m 33 year old.
Editor Rob
Unfortunately not practically...slouching can cause more issues long-term...wear as thin sneakers as possible, grow a long beard to elongate the head, keep hair short, walk on lower side of pavement/sidewalk.
Elliot Christian said on 30/Jun/19
Hi @Rob, I wake up at 187cm first thing in the morning, 185.5 by the afternoon and 184 (sometimes 184.5) by the evening.
Would it be fair to just tell people I’m 6’1”? (185.5cm)
Also, i’m 22 now, when would I begin to see a decrease in my height?
Editor Rob
Many people would claim 6ft 1 with your stats...some might go with 'almost 6ft 1'
Pitaz said on 25/Jun/19
Rob my max morning height is 181.3 and my lowest is 177.8 is that a lot of height to lose..also two years ago my max was 181 and low 177.5 do you think I grew in that period

It is a lot, but sometimes when we are younger our discs are at their best health and can absorb more water.
Pudge said on 24/Jun/19
Hey @Rob if I am 5'10.25 first thing in the morning and about 5'9.5 at night. Would it be fair to call myself 5'10? Also, is there a chance to continue to grow 21 years of age?
Editor Rob
It's unlikely to grow any more...although a small percentage do still gain in 21-24 range, it really isn't that many.

I'd say you could go with about/almost 5ft 10.
Lazar99 said on 23/Jun/19
@Rob,If someone has lost some height due to damaged discs , How could he cure that ? and Is is true that you can't regain the lost height ?
Editor Rob
I think some people through surgery have regained height in back...but also, if their posture has worsened over years, exercise and stretching routines might help them regain their youthful posture.
Buckshot said on 20/Jun/19
If I’m 1.84m at a low would I be lying if I claimed 6’ 1” ?
Editor Rob
Almost/About 6ft 1 might be fair to say.
Jason97 said on 19/Jun/19
Hi Rob. Im 169.5cm in the morning, and drop to 168.7cm in the afternoon (2-3pm) and at night i drop to around 168.4cm (8pm). Is it okay to claim 169cm?
Editor Rob
It's probably fair to go with that mark if you are claiming a metric height.
Hamadd823 said on 16/Jun/19
Rob, what is the average loss in mm between a 2 hour out of bed measurement and a 6 hour?
Editor Rob

Hi Rob I'm exactly 5'11 in the morning so will what will be my lowest height?
Editor Rob
You might fall to 5ft 10-10.25 at worst.
Pitaz said on 16/Jun/19
Rob is it normal to measure 181.5 at my highest and 177.8 at my absolute lowest..I thought It was impossible to lose close to 4cm for someone my height..my highest was 179.8 two years ago so do you think I might still be growing
Editor Rob
That's a significant variation, but not impossible of course.
Daniel McAdams said on 14/Jun/19
Hello, Rob, thought I sent this before but probably didn't go through. I believe I'm 6'4" on the dot, but a week or so back, I measured myself after 10.5 hours of being awake (and after doing some basic weight training) and my height was clocked at 6'3.8/6'3.75 (can't remember which exactly). I always thought you'd be losing height across the day after 12/13 hours or so, so now I'm not sure if I really am 6'4" or not (I don't measure myself often as I don't have the equipment to properly do so at home).
Editor Rob
I think it's safe to still claim 6ft 4 as your height, even dropping a fraction under. I doubt anybody is going to think you are 6ft 3...well a tiny minority might, but 98% will think of you as 6ft 4 at least.
Niloya said on 13/Jun/19
Hey Rob. How should our feet posture be when measuring height? I've noticed there is 4 mm difference between good and poor feet posture.
Editor Rob
Close together is fair, just don't have them a foot apart...a few inches is ok.
Sanya iyiola said on 7/Jun/19
Hi bob. I really love your videos. I am a 16yrs old male. I woke up one morning and my height was 187cm after bed. I decided to check it again and it was 185cm after bed for about an hour. What really shocked was that I shrunk to 183.6 both afternoon and evening. What height do you think I should claim? . And is it possible for me to grow taller?
Editor Rob
The average 16 year old might still have at least an inch of growth, so you may well manage to hit 187cm at night. But even if you stopped now, you are close to 184cm at low, which is comfortably over average and into tall range.

I would claim 184cm just now, but check height in 3 month intervals to see if you gain...sometimes height remains static for a few months and then a person enters a growth phase.
Poop Shoe said on 7/Jun/19
Rob, I have short legs for my height (inseam around 31in) and a long torso. I measure 6’0.4” first thing in the morning but after my standing job and bad posture I can sometimes struggle to hit 5’11.25( not my much but by 1/8th of an inch). Is this odd or not. I’ve measured myself multiple times and it’s roughly the same. On days where I don’t stand/ lift as much I usually end the day around 5’11.5”. What’s the deal?
Editor Rob
It's a fairly sizeable shrinkage, but not that uncommon. Under a more relaxed day you seem to shrink about 0.9 inches.
shantanu lal said on 6/Jun/19
Hey rob i just wanted to tal to you about my height:
Its goes maximum to 185.6 in the morning to low as 183.3-183.6 in night. How much do you think i might be exactly because i cant figure it out !
Editor Rob
Some people with those stats might just call themselves 184cm.
Piers said on 2/Jun/19
Rob, I'm 21 years old and am currently scared that I lost some height.

At the end of April my back started to get more regularly sore during my weightlifting sessions at home (not even serious either, just a pair of dumbbells). There was one session where my lower back just completely gave in and I couldn't keep going anymore. After that day, my back stayed sore all month so I stopped lifting. The soreness disappeared over a few weeks, but then it came back yesterday out of the blue.

During this month, I've been measuring my height. I've always been 186.4 straight out of bed, 185.4 on a lazy day, 183.8 my normal low-- sometimes 183.6. I've been too scared to measure when I come home after I go out, so I only measure on my lazy days... but even then I'm not measuring the same anymore. I drop VERY quickly to 185.4, and struggle to stand straight while measuring so usually get a few mm below that. I only left the house to drive for an hour today, and I've been home for 4 hours. I usually would have regained height all the way back up to 185.4, but I'm barely measuring 184.5 right now.

... Could I have lost some height? I'm trying to be optimistic that its just the soreness holding me back (because again, I can't really stand straights/start trembling while measuring), but I don't know.
Editor Rob
If a disc has been damaged, it might effect height a small fraction...pain could also mean you aren't able to stand quite as tall as you used to manage.

I'd definitely take it easy on your back, or even ask a doctor to have a look.
Minstrels are safe said on 27/May/19
Being 170.5cm in morning and 169.2 at night, would it be a weak 5' 7' be an overstatement? Also how do you define the difference between weak and solid? Cheers Rob
Editor Rob
A solid 5ft 7 won't really fall under the mark and maybe is a little over it, a weak 5ft 7 could be 1/3rd or so under it.
rando182 said on 27/May/19
Rob, when you say that lifting heavy weights/putting stress on the joints could accelerate height loss, are you saying this purely due to the increased risks of injury? For example, say that someone has been lifting heavy for 10+ years but manages to not get himself injured at all. Would you say that person still has an increased likelihood of accelerated height loss over someone who hasn't lifted weights at all?
Editor Rob
The risk of damage increases due to repetitive and large loads placed on discs and joints - but the same can be said of physical jobs that involve lifting too. I do think weight training can be beneficial especially combined with some flexible exercises to strengthen your body.
Heights4 said on 24/May/19
I am 19 years old and my low is 1.69.1 m.I was measured in the townhall as 1.69 m after 2 hours out of bed.I reach my low after just 2-3 hours and dont even shrink a milimeter after that even if i put my body under stress and play football for example.Out of bed im exactly 1.71 cm and my low is 1.69.1 so I shrink 1.9cm.Rob I think you should note that short people like me reach their low pretty quick and dont shrink after that anymore.
Editor Rob
Bodies might respond differently, but on average 5-6 hours gets most people to within a couple of mm of their low range...a few like yourself might find 3 hours gets you close to low.
slothee said on 23/May/19
Rob, do you think when people age they have height loss spurts, or is it just very gradual over time? I’ve seen a few people over 50 who for several years seem one height, then the next year they seem to have lost a fraction.
Editor Rob
I think it can be mostly gradual, but some physical changes might occur over a shorter period (like an area of the spine curving) then remaining about the same for a longer period.
Pat Mongan said on 21/May/19
If I measure 5ft11.6 around 5/6 hours after I wake up what height would I safely be able to call myself? 5ft11 or would I measure 6ft out of bed?
Editor Rob
You'd be a six footer out of bed, maybe 5ft 11.25 at your lowest, so I think claiming 5ft 11 and a half is ok...or 'almost 6ft'
Hiram said on 16/May/19
I’m not sure how tall I am out of bed, but a nurse recently measured me at 2 pm with a wall stadiometer. Height was 183.5 cm. It’s possible I’d fall below 6 ft. from time to time after heavy activity or a late night. Therefore, I guess it would be safe for me to claim 6 ft.
Editor Rob
I'd be claiming 6ft if you got that mark at 2pm!

If you fall under 6ft it won't be by much
so said on 9/May/19
if i'm bang on 5'11 after being awake 17 hours and 5'11 7/8ths in the morning on 6 hours sleep and 6ft on 8+ hours, what height should i claim?
Editor Rob
For a portion of the day you are a fraction over 5ft 11 - whether you want to claim a bit over 5ft 11 is up to you.

Hey, Rob.

I'm around 186.5-187cm out of bed and 184.5-185cm at night, but not really sure if I should say 6ft or 6ft 1 when people ask my height. If I go rucking (walking with a heavy rucksack), I usually wake up shorter the day after. Is this normal?
Editor Rob
In your case, I would say about 6ft 1 for my height.
H18 said on 3/May/19
Rarely i shrink 2.5 cm like today I worked out 3 different muscles in the gym and it’s hot today , usually i shrink just 1.8 cm is these enough reasons to shrink like that ?
Editor Rob
The average is pretty close to 2cm, so you are within average range. 1-1.5 would be a very small shrinkage, 2.5-3 a big shrinkage.
Durr Durr said on 29/Apr/19
Hi, Rob.

What was your lowest registered evening height?
Editor Rob
With proper measuring I haven't dropped under 5ft 8 yet. Give it 15 years and that might be a different story though.
Giancarlos said on 27/Apr/19
!Hello Rob!
How much will be a 1.88 in the morning, afternoon and evening? I usually measure 189.2 in the morning and 187 in the evening ... Do I have 188?
Editor Rob
Some will claim 187, some 188.
Yoshi said on 27/Apr/19
Hi Rob, is it possible that someone in the same heightrange as you could shrink more or less than you? As an example,I read a Comment under the page of Mbappe where you responded that he could pull of 181 cm out of bed. But somehow he is only listed as 178,4 cm. I'm usually 5'10 1/2 out of bed and 5'9 7/8 after 12 hours of beeing Awake. Am I just lucky or is that normal? And by the way, what would you list me as, if I would be a Celebrity? Love your Website!😊
Editor Rob
Yes, you may find some people shrink say 1/4 to 1/3rd more than another person at the same morning height.
Heightguy said on 24/Apr/19
Hey Rob. 3 questions
How many mm would glucosamine tablets add?

How many mm would becoming a more flexible person by stretching add?

How many mm does your height workout add?
Editor Rob
The height workout is for maintaining height and getting yourself into a habit of doing simple exercise to help posture.

I feel there could be some benefit if you don't have great posture to begin with, by doing any form of exercise that involves stretching, but it might be only a tiny amount.

There was a study on Glucosamine and it suggested some people might benefit with evening height by 3-4mm, but I have never tested it.
Frederik Hoff said on 24/Apr/19
Hi Rob,out of bed i'm 178,9 cm. My lowest height of the day is 177,3. Would that make me a Solid 5'10?
Editor Rob
I think more a weak 5ft 10
Durr Durr said on 23/Apr/19
Hi, Rob.

My measurements when I wake up and before bed are usually 1,71.5 and 1,70. However, on some days of hard work already recorded 1,69.5 and on one occasion 1,69.2. How high would you give me on the site if I was a celebrity?
Editor Rob
Really would depend on how you looked in person, or with others. I feel you probably would look about 5ft 7 mostly, which isn't unreasonable to claim...but you still fall nearly a cm under at your absolute lowest though.
Hw18 said on 20/Apr/19
I had a mistake measuring my height with a can, but now I am 168.1 after 15 hours awake and my max is 169.9, what would be my height.
And which tool is the best to give an accurate height ?
Editor Rob
You are a solid 5ft 6 range. Some guys in your position might measure almost 169 at say 10-11 at a Doctor's office and simply claim that height, others might measure late afternoon at nearer 168 flat and go with that...
Anton_20 said on 13/Apr/19
Hi, Rob!
Please, help: What height can I take for the most accurate? And what say, if asked about my height?
Out of bed: 186,2 cm (maximal)
6 PM: 184,0 cm
After training in gym, 10 PM: 183,6-183,7 cm (minimal)
Thank you!
Editor Rob
Six foot half inch range I'd go with...some guys in your position might just say 'almost 6ft 1'.

If using metric, personally I would claim 184cm
Gyan said on 11/Apr/19
I wake up at 166cm and by evening I am only 163cm which is my lowest. My height is already atrocious and this massive height loss really worsens the already serious depression that I am having.
WalkingTall6'3.35 said on 9/Apr/19
Hi Rob,i measured myself 2 days after an hour of walking with some jogging mixed in(15-20min) and i came home half a centimeter shorter.Does running compress your back considerably or what,or do we all measure shorter right after exercise and regain a bit afterwards?

And another question so i don't post twice,which height should i claim? I wake up at 192.9cm,5 hours after mostly sitting at the computer and some walking i'm 191.5cm and in the evening after less sitting and walking considerably i drop to about 191.1cm with lowest ever after all day of physical labour being 190.7cm.I feel like i'm so close to 6'3.5 at noon that i might as well claim that,or is 6'3.25 more fair?
Editor Rob
Some prolonged activity like running will definitely cause the discs to compress quicker to their low range.

Also, stressful rotation type movements I find gets me to my low quicker.
Rampage(-_-_-)Clover said on 9/Apr/19
Assuming he was measured in the afternoon/evening peak I’m gonna estimate he’s lost about 2cm
Rampage(-_-_-)Clover said on 8/Apr/19
Rob, what I mean is did I lie to him because I didn’t measure him at later point in the day I.e. after 1 when a bit more shrinkage occurs?

He’s probably closer 186cm by the evening.
Editor Rob
It depends on how much more he would shrink...he may fall to 187cm by 4pm for instance, but then maybe in his youth he measured at 11am!
Rampage(-_-_-)Clover said on 7/Apr/19
Rob, my uncle just turned 73 and claimed that he used to br 6ft2 and reckoned he’d dropped 1in or so. I measured him the other day at about 11:00a.m. and he got 187.8cm. I didn’t get into technicalities about morning to evening shrinkage nor this site but I told him that he’s still about 6ft2. He was barefoot of course and I did use a stadiometer.

The question I have is did I lie and if he were hypothetically a famous person what would you list him at?
Editor Rob
Did you lie or he lie?

It's very rare to hit 73 without any loss (or 1/4 inch), but not impossible if he has good genes. I would have thought an inch loss would have been more likely for him, but if he got measured 6ft 2, maybe it was a bit over and he didn't care (or be told) a fraction.
Hans23 said on 3/Apr/19
Hey Rob. How tall do you predict a 5'9.25" guy would be first thing in the morning?
Editor Rob
5ft 10 is possible for him
Seamus510 said on 29/Mar/19
Hi Rob I'm 5ft 10 in the morning so will I be 5ft 9 at night?
Editor Rob
Possibly, but you may also be 5ft 9.25-0.5 range.
uzair said on 27/Mar/19
Hey Rob. If I'm 177.5 cm out of bed, what do you predict my evening height would be?
Editor Rob
176 is possible, but I'd say 175 range might be more likely.
Hw18 said on 25/Mar/19
Hi Rob , I wake up 169.5, at 4 pm 168.4, my low is 167.8.
But I reach my low whenever I go to the gym. What’s my height then?
Editor Rob
You can call yourself 168cm I feel, a solid enough 5ft 6 guy
6ft guy said on 23/Mar/19
Hey Rob throughout my childhood I was 99th percentile in height up until age 13 where I was 5'10 and my growth dramatically slowed down. I am now 184cm at 20 years old. Do you think my growth was stunted in some way? I didn't have the healthiest diet growing up. For the record my mom is 5'8.5 and my dad is 5'10.
Editor Rob
I think you probably just followed the earlier bloomer path and just had slower growth after 14...I finished at 14 myself, though I wouldn't have said my diet was terrible, maybe not great, but not enough to impact height much.
Mark T said on 20/Mar/19
Hi rob, in the morning im just under 179cm but by evening i can drop somewhere between 172-174. is this normal?
Editor Rob
That seems unheard of to shrink that amount!
freddy994 said on 17/Mar/19
hi there Rob. i m 25 years old and my height is 179 cm..i read on google that heigh loss can start at about 30. Do you think that if i keep a good diet, stretching every day and exercising, i' d be able to keep 179 cm until 50 years old( if i ll keep living till this age :) ) or even later??
Editor Rob
I did a video a couple of years ago called 5 minute height workout.

This is the kind of basic things I'm doing to help my own back because I have had issues myself with too much time spent on the computer over the years, with not so great ergonomics.

If you reach 50 with no visible loss, you've done well...most folk through to 60 will lose something, maybe a couple mm or even inch or 2. Lots of factors from diet, health, exercise (or lack off), injuries, genetics etc.
Phrygian said on 14/Mar/19
If you are 181 cm out of bed and sink down to 179 cm or so in the evening, would it be normal to claim 180 cm as your standard height?
Editor Rob
There's many folk who would claim that. If you turn up at 11am for a Medical, it's likely you will still be close to 180cm and so that would be in your files.
JG99 said on 12/Mar/19
Hi Rob, if I measured at 5'8'75 at 10pm, would claiming 175cm be reasonable?
Editor Rob
That sounds good to me!
Mickey N said on 12/Mar/19
Hi Rob,
I’m 52 and over the years have been measured at gyms/docs at 186 on at least 5 occasions. However, on a new patient medical once around 5pm they measured me at 184.5. Since then had another 186 measure. Seeing your video I’ve tried the aerosol can method as it touches my head and whilst 186.5 out of bed have found myself 185 around mid afternoon. At shortest 184.3. Considering my history is 6 1 fair enough to claim. Think rounding to quarter inches sounds a bit anal to many. Also how accurate is self measurement and knowing exactly when it touches your head/ right angle etc?
Editor Rob
If you bring the can down slowly, you'll feel the coldness on the top of your scalp, it should essentially be sitting on the head. At your age you might have lost a small fraction, but the self measurement is quite accurate, but it depends on the wall/floor being perpendicular and not have much sloping at all.
confusedheight said on 4/Mar/19
Hi Rob, I had a physical in late January at 8 am. I got only 3 hours of sleep, and was fairly dehydrated as I was required to fast, and was feeling pretty compressed. I was measured and was listed at 5'8 exactly (172.72 cm down to the hundredth). Would they round heights? I don't know that I was standing fully tall, especially since my self recorded low height has continually been 5'8.25 (173 cm) over a few weeks that I checked. If I'm 5'9 exact out of bed, 5'8.5 for most of the day, and 5'8.25 at night, and supposedly 5'8 at my physical, what would you say my height is? Is claiming 174 cm wrong?
Editor Rob
I personally wouldn't claim it...but for you, since it's bang on the middle of your tallest and shortest measurements, it's not too unreasonable.

If you claimed 173, I doubt anybody would ever question your height. If they did, it's just guessing wrong, which happens to everybody - you can be guessed taller or shorter. Ultimately all it means is the person guessed different than the measurement.
Liam1 said on 28/Feb/19
Hey Rob. If I'm 178 cm out of bed, what do you predict my evening height would be?
Editor Rob
177 at most, but 176 range is likelier.
WalkingTall6'3.35 said on 28/Feb/19
Hi Rob,i am almost 192cm now at the age of 26 with a big frame and i'm wondering how much height will i lose later in life.How long will i be able to ''maintain'' at least 190cm?
Editor Rob
On average, you might lose more height because of frame size and overall height. A 5ft 5-6 man with a much shorter spine than yourself, could lose half the amount.

Now, keeping a good diet and not becoming very sedentary, by even maintain a simple exercise routine as you age, may help you reduce losses a bit.
Martin 6'2 said on 22/Feb/19
Hey Rob, I was just wondering, I'm 6'2" barefoot morning height, and I've just turned 33, I actually do a lot of stretching exercises, do you think these could go in my favour to help maintain my height?
Editor Rob
I think doing even a simple 2-3 minute of exercise a day can help long-run.

it's about just getting into a routine. I done this 5 minute height video just to give people the basics of using a bar to help strengthen and keep your posture good.

You already seem to be doing well by getting your own routine going. As I say, 5 minutes a day in the long-run is all we need.
Fouat said on 21/Feb/19
Hi rob, i wake up at 172.3-5 and my low is 170.7-9, so i was wondering if claiming that im in the 171-172 range is ok?
Thank you
Editor Rob
many guys with your stats would claim 171, many 172 also. Claim what you feel comfortable. It's not like you are saying something like 174 and inflating your height.
Harry said on 20/Feb/19
Hi Rob. Do you think that being very physically active in your youth, like doing lots of long distance running will accelerate height loss quicker than the rest of the population (due to strain on joints etc.) or do you think it could actually help to maintain height as you get older by keeping you in good shape and strengthening back/leg muscles?
Editor Rob
I think some athletes do suffer in later life. It can catch up with them...
yekat said on 14/Feb/19
Hi rob, I’m a just turned 16 year old girl. I wake up at 174 and my low is 172, so I claim 5’8. My mum and dad both grew until 19-20 (they are 5’6 and 5’11, and my mum went from 5’2 to 5’6 at 18), and I’m predicted to reach 5’10. Do you think it’s possible? I model and I just love being tall :/
Editor Rob
If your Mother gained height near 17 then the odds are decent you may still gain 3-4cm to reach 177-8cm. That is an optimal height for being a model.
Clarky said on 11/Feb/19
Hi Rob I recently ran across your site and find it very fascinating. I have some questions if you could kindly answer them. You slightly addressed this elsewhere in your website but I just wanted to clarify, when it comes to the listed heights are they peak, lowest, or somewhere in between height? Also, related to this, when it comes to national studies that study average height like the National Health and Nutrition Examination Survey (NHANES), would you happen to know what time of day these heights are recorded for official studies? Do they take it into account at all? Lastly, when it comes to claiming heights, I noticed you claim your lowest height. Why is that and do most people claim their lowest height or do they claim a height earlier in the day. Thank you very much Rob.
Editor Rob
As I said the other day, around early afternoon is a reasonable time to think of height, I don't really think of celebrity heights as being first thing out of bed.
179cm guy said on 7/Feb/19
Hey Rob, in your opinion do you think that anyone who measures between 176.5-178.4cm (5'9.5-5'10.25) barefoot after eight o'clock in the evening can reasonably claim 5'10 without any other disclaimers such as "about", "almost", "on the dot", "a smidge under/over", etc. for those who don't want to come off as being insecure or pedantic to others? What about anyone who measures between 179-181cm claiming 5'11?
Editor Rob
I think it's reasonable to just round to 5ft 10, though if you dropped any more below 5ft 9.5 I think I would probably just stick with 5ft 9.5.
Folly said on 7/Feb/19
Rob Paul, I wake up at 175.5 cm. What height would you give me on your PageRank if I were a famous celebrity. And am I considered short with that height?
Editor Rob
Depends on how tall you look in person or beside others. But you might end up at 5ft 8.5, though 5ft 9 isn't impossible if you had great posture and higher eyelevel.
Preeme said on 4/Feb/19
Hi Rob, is it possible to lose a bit of height at age 20?
Editor Rob
Injury can do it, like damaged discs...but I think if you lose anything noticeable, see a Doctor.
Grimesy said on 3/Feb/19
G’Day Rob,

First of all, kudos on such an awesome site !

I have always claimed myself as 5’7 (170cm). The other day I got my height measured while getting a body scan. This was at 4:30pm in the afternoon. I work an office job so had been sitting down all day, although went for a 30 minute walk around lunch time. I measured 169.4cm. Is it still acceptable to claim 170cm (5’7) as my height in your view ? I would assume I would definitely be above 170cm first thing in the morning ?
Editor Rob
Considering the time and 6mm under, I think most people would round up because for 9am through to say 2pm you are probably over 170 then a bit under it.
179cm guy said on 1/Feb/19
Rob I just made a shocking new discovery pertaining to my families' height-related genetics and growth pattern. I just recently measured my mother who just turned forty-eight this month and she clocked in at a flat 5'6.5 at 8:30 in the evening. That was to be expected since she's always claimed to be 5'6 or 5'7. But the interesting thing is that I found myself looking at her driver's license on which she was only listed at 160cm (5'3). When I made her aware of this she was just as surprised as I was and the only conclusion that she could come to was that she had grown 3.5 inches after she turned sixteen. She asserted that she had been measured at the Service Ontario centre where she got her driver's license when she turned sixteen and that that's the height that she had been going by ever since on all of driver's licenses. My uncle (my mother's brother), also grew to be 6'4-6'5 Rob do you think that given this newfound information that I might be able to grow a little more even though I'm already eighteen years old?
Editor Rob
It's something worth considering, because maybe your Mother's late surge could increase a chance of 18-21 growth for yourself.
Son of Thompson said on 17/Jan/19
Hey Big Roberto,

I am 176.5 at night standing up as straight as I can. My doctor measured me at 177cm at around 1230 in the day, should I say I'm 177cm?
Editor Rob
I would say it's quite reasonable to be claiming 177cm. For a large chunk of the day you are around that (a bit above and then a bit below).
khaled taban said on 8/Jan/19
Rob, I have been measuring my height for a long as 174.5 cm, then all the sudden I measured it as 173.7cm till today. I am wondering what causes that. Do you think I can get that 1cm again? I am only 19 years old.
Editor Rob
Seems a big difference. If you switched the method (like the room/wall) it might account for that, but if you were doing same time of day, same wall etc...it's a mystery!
Ninio said on 3/Jan/19
Rob thanks for answering
I measured myself about 6 hours after being away and dehydrated at 168.4-5 and after after many hours after being dehydrated I ve realised I've gained 2-3mm do you think it's reasonable to hit your lowest range early and what do you think a perfect listing for me. Thanks!
Editor Rob
If you tell people 168cm, everybody will think you are an honest guy. Say 169cm and the vast majority would also think you were about that, unless you walked about in thin slip-ons.
Ninio said on 3/Jan/19
Rob getting badly dehydrated can affect height by about how much?
Editor Rob
it might only be a few mm, but being badly dehydrated, can mean the body uses up more water content from the soft tissues like your discs, so possibly shrink a few mm further.
Mosa said on 3/Jan/19
Rob, I personally think that I haven't achieved my full genetic height (probably because I didn't sleep a lot during my growing years). I think I am something like 2 cm below my real genetic height. Do you think that this is a common think that people do not reach their full potential height?

Thank you for anwsering the question.
Editor Rob
I think it was more likelier in some past generations that had more restricted diets or illnesses which effected their growth. It's still possible today not to reach potential.
Ninio said on 30/Dec/18
Rob is it reasonable to add 7 mm to your "before bed height" to know your actual height?
Editor Rob
I think if you get measured at 10-1pm at an appointment, then it is perfectly reasonable to go with whatever that is...you might drop another 4-10mm, but nobody will notice. They will notice those who add 1-2 inches though.
Hayley Harrison said on 29/Dec/18
Rob, Is there any chance of stopping my spine shrinking an inch during the day, It makes me very frustrated because then I feel I’m shorter than I should be? I have a lot of back pain too, could there be something wrong with my spine?
Editor Rob
There was a study done on glucosamine tablets, which might help your discs retain a tiny bit more height...you are talking a few mm's difference in evening height.
sa123489 said on 29/Dec/18
Rob, I’ve been 173-174 cm since the age of 13-15. This is a relatively young age to finalise growth so does that mean I could experience height loss earlier?
Editor Rob
I don't believe you would experience loss any earlier...there are factors like exercise, type of work, nutrition which play a more important role as to how much you could lose. Genetics and risk of osteoporosis too
Emil J said on 28/Dec/18
Hello Rob
I at my tallest at 183 cm in the morning and at night i am 181 at my lowest
What do i claim? I mostly just claim to be 183
Another thing... I have had a lot of back pain for the last year, and i wonder if that could´ve caused a slight loss of height?
Editor Rob
Back pain could be a result of overworking or poor sitting positions.

If I was 181 at my low and 183 in the morning, personally I might have went with 181 or 2.
Zaveid said on 27/Dec/18
Hi Rob, I measure 183.2 out of bed, 181.6 - 7 hours out of bed, 181.3 - just before bed, 180.9 - as my ultimate low (after a long day of walking, lifting weights, staying up for 24 hours +) What height should I claim? Is claiming my ultimate low downgrading myself? What height do you use to list celebrities (do you use their evening height or their ultimate low?). Thanks a lot!
Editor Rob
Always claim what you feel comfortable.

181 is basically your low - so you could be confident should you ever be measured that you won't come in under. I wouldn't say it was lowballing...some guys in your situation who weren't as aware of height variation would get measured at the Doctor's at 11am and be near 182 and claim that without hesitation.
Rem said on 27/Dec/18
Hi rob. Thanks for all your stuff!!! I have just turned 20 and gained 3mm in a month. It is not noticeable but it is something for me. From my 19's i have growned 1.5 cm until now, in more a less one year and some months. I was 173.8 and now i am 175.3-4 at my lowest. What is more i was called short in school but now even my taller friends tell me im not short, and some even say im tall. Do you think that working on my posture gave this 1.5 cm increase and illusionnof being tall? (I have goy scollisis)
Editor Rob
It sounds possible that your spine wasn't optimal, and the exercises have helped you achieve just that little bit taller a measurement.
Alkin said on 25/Dec/18
Rob, is 1,5 cm height difference noticeable?
Editor Rob
If the people being photographed have the same hair thickness, most should be able to tell there is a difference...though, if you have varying hairstyles or head sizes, sometimes that 1.5cm can seem much less...or even a bit more!
carrtman said on 25/Dec/18
Rob, do you think those socks lifts really add 2 cm of height like it is said in the ad or less than that ? Click Here
Editor Rob
The company probably are measuring the height at the very back, it might be only about half inch or so if you tested them...they are expensive though, but then are far better designs than other ones that are cheaper.
179cm guy said on 23/Dec/18
Hey Rob!
I have a question for you.
I just turned eighteen and I'm a solid 179 cm guy on an average day and 178.5cm at my absolute low.
I've always been a late bloomer (at fourteen entering high school I was almost 5'6" and now I've finished high school at almost 5'11").
I have extremely long legs for a guy my height (34" inseam) and I still retain a somewhat boyish looking face.
My mom is a 5'6"-5'7" range lady and she has a brother who is 6'4"-6'5".
My dad is a 5'9"-5'10" range guy and he has a brother who is 5'5"-5'6".
My younger brother (sixteen) who hit puberty earlier than me is the same height as me now.
My dad stopped growing at around the age of sixteen although he had a problem with his thyroid which might have cheated him out of a quarter to a half an inch of height.
What do you think my final height will be within the next few years keeping my late-blooming tendencies, long legs, and boyish features in mind?
What do you think Rob? Please answer, you're the best!
Editor Rob
I'd take any more growth as a bonus...there are some guys at 18-21 who might increase exercise or do a routine to maximise any potential left. I think there is a chance of 180-181.
lastman said on 23/Dec/18
Rob, I have a question : I'm 5ft 6 and a strong 5ft 6.5 out of bed, which means that I only gain about half of an inch during a full night of sleep. Is it normal to get so little or should it be more ? Also do you think I may recover my "out of bed" height of 169 cm by lying in an Inversion table and use it to hang upside down for several minutes so that my spine can decompress completely ?
I've read an article here about that : Click Here
Thank you for your answer and merry christmas !
Editor Rob
Inversion over a long period of time might help your morning height a bit...it could create a temporary boost, but needs daily repetition of using the table.

Half an inch shrinkage is a bit less than average, but maybe not so much for 5ft 6 range people.
anton1999 said on 21/Dec/18
Hey, Rob!
I need your advice:
I am 186,0 out of bed and 183,8-184,3 in the evening.
What do i claim to be?
Can I still grow up 1,5-2 cm? I am 19 y.o.
Editor Rob
After 19 it is more rare to grow, though of course a percentage still grow 19-21 or even 23.

At the moment you are a decent 6ft 1/2 inch guy.
Ethan, 190cm said on 17/Dec/18
Heyo Rob, don't know if you remember me I was the guy who was curious about my height just before my GCSEs and I was stressing. But good news! I passed with flying colours!
I am now turning 17 in the latter part of April and I am a weak 190cm and my question is... Will i reach 6,4?
Editor Rob
At 17 some folk finish, others still gain a bit, some even a few inches more...at near 190 I wouldn't give it much thought, already it's a very tall height. 193 is possible. Report back in a year to see what happens!
Charles Giege said on 16/Dec/18
Wassup Rob, do you think weight gain leads to height loss? Because I am pretty sure I've shrunk ~3-4mm after gaining 10-15 kg
Editor Rob
I think in a scenario such as 100 pounds, it might effect the spine a little or cause somebody not to stand quite as tall as they used to. Small amounts though like 20-30 pounds I doubt it has any sort of effect.
akee said on 1/Aug/18
Rob if im 175.26 with an inseam of 30.5 inches is this still within average? noticeably quite short?

Yes it's within average. Under 29-30 is shorter.

The type of trousers/jeans play a role in how you might look.
cmillzz said on 29/Jul/18
Another question for you Rob: why are disc injuries so common? I just think it’s weird that our bodies were designed that way. It shouldn’t be so easy to have disc injuries, yet it happens all the time with many people. Do you have an explanation as to why it’s so easy to injure our discs? I just don’t get why our discs have to be so fragile.
Editor Rob
Over exertion or excessive loads can cause these disc injuries.
cmillzz said on 27/Jul/18
Rob, I lose a huge chunk of my morning height in the first couple hours, is that normal? I’m closer to my evening height after just two hours out of bed, whether I’ve been standing or sitting the entire time.
Editor Rob
Yes, the first 2-3 hours of being awake will cause us to lose a good chunk of morning height.
yuity said on 26/Jul/18
rob is 1.5 inch shoe really noticeable?
Editor Rob
Yes, a 1.5 inch heel is quite big, well for a man's heel. It is more obvious, but if you are looking down at somebody's shoes from within a few feet you probably wouldn't notice it being thick.
juder said on 26/Jul/18
hi rob I measure 5'9.25 after working 12 hours on my feet all day no less, and on my days off I measure 5'9.5 at the end of the day. would you say I am a good 5'9.5? considering I wake at just under 5'10 maybe even the full if well rested.
Editor Rob
Calling yourself 5ft 9.5 I think is fair enough.
judas said on 26/Jul/18
hi rob would a 30.5 inch inseam be average for 174cm ?
Editor Rob
It is within average range yes, though if it was 29.5 it would be into a more shorter range.
xsxs said on 23/Jul/18
rob does smoking effect our height in any way?
Editor Rob
Long-term it isn't good for your body, including height - with age, smokers are likelier to suffer more issues that could knock a bit more height from their frames.
Kirke said on 22/Jul/18
Rob, do you have any advice for getting tallest possible measurement 5-6 hours after waking up?

Thank you.
Editor Rob


I think avoiding tasks that put stresses on spine. Even something like doing washing up puts more strain on our spines than you'd imagine. Keep hydrated during the day.
Sitan said on 19/Jul/18
Rob, is 2 cm a typical shrinkage for someone who wakes up at 192 cm? Or perhaps a full inch?
Editor Rob
2-3cm range would be typical.
cmillzz said on 19/Jul/18
Rob, do you think a disc herniation in the lumbar section of the spine would be more likely to cause height loss than a herniation in the cervical section?
Editor Rob
Both can have effects, but lumbar are a bit thicker so potentially damage to those discs could give slightly more loss.
juus said on 17/Jul/18
rob would taking an average of my morning height and night height be correct? I want to claim a height that i average over the day and measure at even several hours after being up sometimes, around 5 to even 7 hours. Also why do you claim you're absolute low of 5'8 and 1/8 rob? you clear this height a majority of the day?
Editor Rob
It's not unreasonable to go with that, I know a fair few people who might do it.
Canson said on 16/Jul/18
@Rob: in regards to Jason Wick, what do you consider inflating or deflating your claim? And where do you fit the “out of bed” height and “extreme low” (height that you only hit once in a while) into the equation as far as a claim?
Editor Rob
Whilst out of bed is a height you measure,I think claiming it goes against what most people claim - which is the height they measure after being awake several hours.
Adding an inch or pretending shoes are part of human height is to me an inflation, and rounding down an inch or even if 5ft 8.75 and saying 5ft 8 is a bit deflating.
hmmm said on 14/Jul/18
Hello Rob,
very strange situation. I can walk, play football whole day (13 hours) and shrink only 1,5cm. But in other day i can do completly nothing and shrink 2 cm. Common is 1,5cm range but something is like i told. Its because bad hydration or what?
And one more think, if i have curvy spine can i get from him 1-2cm more after fix posture?
Editor Rob
Might be hydration, but also sometimes the way you sit in a chair can place excessive pressure on discs that can contribute to greater loss. Driving I've found gets me down to my low quicker than sitting on a computer chair.
Sitan said on 13/Jul/18
Rob, I am in a military and we wake up at 6 AM every day. Today I measured myself 15 hours after waking up and I was 189,2 cm. Was this my lowest measurement?
Editor Rob
Without becoming really dehydrated, about 189 might be your real low mark.
Westworlder said on 13/Jul/18
Rob, does tight/restricting footwear make you lose more height during the day? I have some tight shoes that squeeze up my feet sometimes and I feel like I lose more mm wearing them than when I wear more free/fitting footwear.

I don't think it affects my spine in any way, so I guess I'm wondering is it possible to lose more height from your feet tensing up?
Editor Rob
I can't see how it would effect height directly.
Bobby said on 9/Jul/18
So, this is saying that you'll begin losing height by age 30? I find that extraordinarily doubtful. I see no reason to believe that I won't measure 179cm in the morning at age 30 as I do at age 23.
Editor Rob
After 30 for Women, but we are talking a tiny amount up to age 40...even for men, it would be a tiny amount on average.
David Sullivan said on 8/Jul/18
Hey Rob, what would you give your height as if you were me?

73" seconds out of bed
72.375" 4-5 hours on feet
72.0625" lowest i've recorded

Incidentally I get 6-2 alot from other guys who claim 6'. Strange how the lying affects everything
Editor Rob
You are a solid enough 6ft that you will annoy other 6ft men who are claiming 6ft 1-2!
ryte said on 6/Jul/18
hi rob would thick socks increase height by much?
Editor Rob
If they were tightly woven they might add 2mm, but most I've seen barely add even 1mm.
Laduski said on 5/Jul/18
Rob, is it true that people with big foreheads usually have lower eye level?
Editor Rob
It is quite common.
gege said on 4/Jul/18
hi rob. Do you know how the national averages are done? and if so what time of day they measured
Editor Rob
In the UK, the national health survey would have taken place on average around lunch - the people doing testing would go to different homes during the day to do survey, including height measurement, so overall we are looking about mid-day as the average.
Mahesh jayan said on 3/Jul/18
Rob have u experienced noticable height loss in celebrities ( like more than 1 inch) while meeting them in different periods( like in gap of several years)
. Can u pls post comparison pictures if u have any?
Editor Rob
There are a few I'd say looked say half inch shorter after I seen them over the last decade, people like Kane Hodder seem shorter than they did 10+ years ago.
john wick said on 28/Jun/18
rob what is my actual height I wake at 69.875 inches and go to bed at 69.25. I have measured once or twice in the evening (5-7 hours of being up) and got 69.5 inches.
Editor Rob
Some folk go with the average or a lunch time height, others go with morning or evening.

As long as you are not inflating or deflating your claim, I think in the middle of your range is perfectly reasonable to tell people.
mayn said on 28/Jun/18
hey rob is 5-6 hours a good/legitimate time to measure height? given i have been at work standing/lifting things
Editor Rob
Yes, I think stating your height around that long out of bed is rather reasonable, you won't shrink that much more.
bruny said on 28/Jun/18
hi rob i am 174cm and was wondering if i am firmly within average for the uk. (would i be seen as short) ?
Editor Rob
It's just under the average, so definitely not short.
Micha? Fronc said on 28/Jun/18
Hi Rob, I have 177 cm out of bed, then 175.3-175.5 cm in the evening. Can I claim 176 cm as my official height? Greetings from Poland :)
Editor Rob
If you went to the Doctor's at 10-11am you would be 176cm, so many people would claim that.
rambo slice said on 25/Jun/18
Would going completely bald make you look shorter rob? I am of average height at 174cm and live in the uk where the average is 175cm.
Editor Rob
I think it can sometimes. Certainly hairstyles of varying thickness can sometimes enhance how tall somebody looks.
DanTheGuy said on 24/Jun/18
Hi Rob! I was just wondering if you've shrunk at your age (which is?), and does an inversion table prevent height loss? Thank You! P.S. do you ever get called short at 5'8? Thanks again!
Editor Rob
I've yet to lose height, but I'm only 41 :)
In the real world I haven't heard short used that often. Online I think you will find it used to describe 5ft 8 as short far far more than in real life.
yoyo said on 23/Jun/18
hey rob. What is an average eye level? mine is just over 4 inches is this normal
Editor Rob
The average is around 4.5 inches. 4 is a high, 5 a low.

If we have two people the same height, you will find some with nearer 4 and some with nearer 5. In such a situation the person with 5 inch will think the other is taller, since nearly everybody is judging height from their eyelevel.
yuley said on 23/Jun/18
rob so hair makes no difference to our measured height, would you say hair makes any difference visually ? Like if two people were the EXACT same height but one had more tuff up there would he get pegged as slightly taller by many?(have you done this before) or would it make virtually no difference because people can see he is not taller just has more hair.
Editor Rob
Well the difference is tiny...but if some people had thick and coarse hair, that has some potential to effect the measurement. The person might not push down fully and if they do, there may well be a bundling of hair around the point where the can hits the head.
yer said on 23/Jun/18
Hi rob bit of a silly one, can damage to a rotator cuff effect our height?
Editor Rob
It might effect your posture slightly, but it won't have any effect once healed.
wert said on 21/Jun/18
Hey rob would you say getting massages are necessary, and could they help increase our height? Or would keeping good posture and doing yoga be more then enough.
Editor Rob
I think they are beneficial, but won't make you increase height...apart from maybe help make you more supple, which I suppose might make you hold a better height.
master said on 21/Jun/18
rob would you say if i have a wingspan two inches greater than my height I have long or relatively long arms?
Editor Rob
A little longer than the average, but if it was 3-4 inches that would be quite long.
Bwin said on 21/Jun/18
Rob would you say that most people gauge others height by comparing eye levels? Is this a good way of guessing height given the person in question doesn't have an abnormal eye level?
Editor Rob
Yes, nearly everybody would guess height from their own point of view (eyes).

If you had a very high or very low, you might have to account for that with your guessing.
juu juu said on 21/Jun/18
rob as you are a strong 5'8 (just below average) if you lost all your hair do you think you would still be in that category
Editor Rob
When you use something like an aeorosol can, the surface area at which it touches your head is tiny. You then have the thickness of hairs....so it has no real effect (fraction of a mm), I can feel the can touching my scalp when it sits on the head.
james11 said on 19/Jun/18
rob am I ok to claim 5'10.5 if I wake a few mm under 5'11 in the morning and 5'10.5 about 3 hours after.My absolute lowest is 5'10.2 inches
Editor Rob
Considering it's 1/4 above your low, I don't think it's unreasonable :) Especially when half the population are lying 1/2 to 2 inches.
brucww said on 18/Jun/18
Rob I get almost a quarter inch difference more in height when I lock/tense my knees, would you consider this cheating? I measure 5'9.5 after 5 hours of being up working with some heavy/moderate lifting and want to know if I can claim it. Without locking my knees I measure at 5'9.25 .
Editor Rob
I wouldn't consider that cheating, but rising up on tip toes would be a bit cheeky.

Claiming 5ft 9.5 is reasonable enough.
Leno179 said on 15/Jun/18
Hi Rob, i am 18 years old and currently 179.7 at moment i believe, and i really liking working out, but in a safe way, sometimes i do lift a little heavier, but never at a point of super heavy, that could damage something and cause an injury. My doubt is, being phisically active, would helped grow an inch or even two ? I also stretch a lot to help my mobility and overall posture. I heard in some places it does help, but I want to hear it from you, cause is always good to listen to others opinions and learn with what the other know.
Editor Rob
There are certainly a proportion of people who can gain another bit of height from 18 to 21, and being physically active might help the body respond to the demands it is being placed under and grow.
kiki said on 13/Jun/18
after which year of human life height of people of reduces,and for how much cm can be reduced in life?
Editor Rob
Some people might lose height between ages 40 and 50, but it is usually on average quite small.

More people will see height loss from age 50 to 60, but when you reach age 60 and towards 70, that is a decade in which the vast majority of people will experience some height loss.
Altonn said on 13/Jun/18
Rob does knee valgus affect height?
Editor Rob
That condition could make you measure a bit shorter than normal hip/knee positions would.
Rem said on 12/Jun/18
Rob, ive got 2 questions. The first one is, do you think that playing an 18 hole golf tournament makes you hit your lowest?
And the second one is, do you think that drinking 1.5/2 LTS of water throughout the day will keep you well hydrated so that you dont hit your lowest height?
Editor Rob
I think it has potential to get you near lowest, because the act of practice swings and actual swings, plus walking puts a lot of strain on the spine.

Maybe not quite as intensive as something like a tennis or football match, but the rotating aspect does effect your discs.

Keeping well hydrated will help the discs, but we are talking a small amount. Your body can get to a bad dehydration state in which it uses water from soft tissues like the discs, which would be a reason for losing another few mm's and hitting an extreme low.
Altonn said on 12/Jun/18
Rob, what kind of impact does sleeping has when it comes to growing in teenagers?
Editor Rob
Very important to help achieve near maximum genetic potential...it's when the body can heal, repair and grow.
cmillzz said on 11/Jun/18
Rob, sitting puts as much stress on our disc as standing? I notice after hours of sitting I’ll shrink down to my low almost as fast as standing. Is that normal?
Editor Rob
Yes, sitting places strain on the lumbar section of our spines. Driving isn't good for the back, as the sitting+low level impacts from bumps won't help the discs.
brucw said on 11/Jun/18
hi rob so you are saying locking your knees will give you a slight increase in height? When I measure myself it feels natural to lock the knees and stand tall, I get taller measurements this way maybe it has something to do with my posture. are these legit measurements still?
Editor Rob
Anything where you are standing at your maximum posture is your tallest height measurement...if you go up on your toes then that's taking things too far, flat footed and head straight and standing tall (even breathing in) gives you the maximum measurement.
Altonn said on 10/Jun/18
Rob, I'm a 6'3" guy and I have a friend who is also 6'3". However, I feel that I shrink more than he does. Unlike me he is physically fit and has a low body fat percentage. Could this be the reason for a lower shrinkage?

Thank you for anwsering the question.
Editor Rob
Genetically people can vary. Your discs maybe can retain more fluid overnight than his.
Asar said on 9/Jun/18
Rob, do you believe that our maximum genetic potential height is our morning height?
Editor Rob
It is our peak height measurement...but for stating our height, most people never measure within 30 seconds of wakening, so giving a height after x hours fits in with how other people give their heights.
Kiky said on 8/Jun/18
Rob, I am 190,3 cm 5-6 hours after waking up. Can I reach 190,5 cm by drinking a lot of water every day? My main goal is to be a flat 6'3" and I am only a couple of millimeters below it.
Editor Rob
If you sleep on your back with 1 pillow for 9 hours that might get you there...but even a few weeks of something like a simple exercise routine Like my 5 minute height workout might help achieve a slightly better morning height.
Leigh said on 7/Jun/18
hey rob if I measure 178.5cm or 5"10 and a 1/4 out of bed and then 5"9.5 at night would should I claim?
Editor Rob
I'd probably go with 5ft 9.5, or some 'about/almost 5ft 10'. That kind of covers your range.
fut said on 7/Jun/18
Hi rob how much lift would a pair of Nike air force 1 low's roughly give?
Editor Rob
There are 1.25 inch styles of air force and 1 inch styles.
Hammer said on 6/Jun/18
Rob my out of bed high is 1/8 of a inch under 6ft 6. My low is 6ft 5. A extreme low for me is 6ft 4.75. Do you think 6ft 5 is a good claim for me or can I get away with a 6ft 5.25 claim?
Editor Rob
I'd stick with 6ft 5 if people ask. It's a fair mark to go with.
Asklar321 said on 6/Jun/18
Rob, how many millimeters can be maintained by staying hydrated?
Editor Rob
The body can vary in hydration levels, so fully hydrated it's not needing to use up any water content from soft tissues. If it's badly dehydrated it will be using water from soft tissues (including discs in spine) which is why bad dehydration could result in a fraction less measurement.
But moderate dehydration might not have a great effect, like 1-2mm
brucxw said on 3/Jun/18
hey rob is it normal to lock you're knees when using the can and tape measure method? Its very hard for me not to.
Editor Rob
It doesn't really make much difference to height.
juju said on 3/Jun/18
rob one day after working a taxing 7 hour shift I measured at 5'10.5, I measured a few days later after a 5 hour shift with much less work involved and measured at a mm or two over 5'10.25. I was not dehydrated either how can this be?
Editor Rob
It's always possible you were doing some rotation moves or moved certain ways that suddenly put bigger stresses on your spine and made the discs compress slightly more.
Harry said on 3/Jun/18
Hi Rob. I ran a half-marathon in Huddersfield and measured myself in the morning as 168.1 and 59.8 kg and I measured myself a few hours afterward (with excellent posture but not quite busting gut) at just barely 166 and 57.7kg. I finished in the top three, but what surprised me was all the top three runners were 5ft 5-7 range. A photo was taken at the end, and you might see it online on Huddersfield Examiner (I am in red and blue vest, with crazy hair as was quite windy). I think long-distance running is one of the few sports where being below average height actually helps (provided you are very thin), and I came across this article (Click Here) that I thought was interesting too and if you look at all male world marathon and half-marathon record-holders, a large number are below-average or short. Do you think I should claim 166 or 167cm, given that this measurement was very near an extreme low, and do you think being short or below-average height actually gives you an advantage in long-distance running?
Editor Rob
A smaller, more lightweight frame certainly might help with marathon running. I'd claim 167 if I were you.
Lr12 said on 3/Jun/18
Hey Rob,

I measured after 11 hours and hiking 22km 188cm. Do you think i reached my absolut lowest?

Thank you for your answer.
Editor Rob
It's unlikely you will shrink any further...unless you became dehydrated badly, that might knock 2-4mm off again.
beem said on 29/May/18
Rob why do you claim your lowest height not you're evening height? Is 5-6 hours out of bed a good time to measure my height given I have been on my feet working for 5-6 hours, or do i claim my low. I wake at 3mm below 6 foot and measure myself 5'11.5 after being at work 5/6 hours. But my low is 5'11.25, would I really be adding a 1/4 inch to my height by telling people 5'11.5 in you're opinion?
Editor Rob
For me, I can reach my low range after 6-7 hours...but some people can still shrink another 1/4 inch after being up 6 hours.

I think if you claim 5ft 11.5, that sounds perfectly reasonable for you.
squat said on 28/May/18
hi rob I dont know what height to claim, I measure 5'10 in the morning and after working a 6 hour shift have measured 5'9.5. MY low is 5'9.25, 5'9.5 seems a good median?
Editor Rob
I don't think many would ever challenge you if you claimed 5ft 9.5
squat said on 28/May/18
rob In your opinion would bald people look shorter opposed to having a set of hair?
Editor Rob
Hair is an advantage, though some people might chop off more hair when comparing heights because they can't always be sure exactly where the top of the skull is underneath it all.
cmillzz said on 27/May/18
Rob, if you have a disc injury will that result in a greater difference between your morning height and evening height? In other words, will a disc injury only affect evening height? Or will it have an affect on both evening and morning height?
Editor Rob
I wouldn't think the injury would change the overall shrinkage from morning to evening.
Jake Iscariot said on 26/May/18
Hey Rob, in the morning im 172cm but I've noticed on days I do heavy weights at around 10/11 am by 2pm ive shrunk to 171cm ive been doing weights over 2 months now and can lift 10kg more than before. Should I just claim 5 foot 7 ? as I lift 3 days a week
Editor Rob
Claiming 5ft 7 is very reasonable. I doubt you fall much under that mark, even if that!
bubbler23 said on 24/May/18
Hey rob is it safe to say a 5'8- 5'9 dude wouldn't be seen as short in the uk then? I get some comments from guys standing no taller then 2 inches taller then me rarely though, and those guys are normally complete ****s anyways.
Editor Rob
Height can be relative. The 6ft to 6ft 4 men will think 5ft 8-9 is short...but overall it is on the lower end of average range.

You might get the odd short comment.
Oliver said on 23/May/18

Rob,I'm 5ft 7¼. How tall do you think my mother is?
She said she was 4ft 11 in her prime. She's now 62 yrs old.
Thanks alot.
Editor Rob
She might be 4ft 10 today...and lost an inch.
Ja533 said on 20/May/18
Hey Rob lately I've been waking up around 2/16 of an inch lower than my normal morning height. in the last week I've been stressed out and been getting 6 to 7 hours of sleep compared to my normal 8 9 hours of sleep does the stress have anything to do with me not reaching my normal morning height
Editor Rob
That 6-7 hours might be effecting your almost 1/4 inch difference.

Also hydration levels and sleep disturbance might have a couple of mm effect too.
louis5 said on 16/May/18
rob does our hair effect our measurements? relatively short hair wouldnt make a difference no?
Editor Rob
Hair isn't really worth bothering about unless it is really thick, is in braids or you aren't putting the object flat on the head.
Dave618 said on 15/May/18
Rob I wake up around 11 am. Would 7 pm still be a good time for me to measure lowest ? Or should I wait couple more hours say by 10 or 11 pm? Thanks for the response.
Editor Rob
If you are active during the day, then 6-7pm could be a low.

If you lounge about and relax watching Netflix or something, then you might even creep back up a couple of mm after 7pm.
jety said on 15/May/18
rob is 174cm average for us/uk ?
Editor Rob
It's certainly within the average range, but we are talking a little shy of the average 5ft 9-9.25 figure.
0oiq said on 13/May/18
hi rob what are the chances of my walls/floors being innacurate? I measure on 3 walls and all are exactly the same
Editor Rob
Depends on who built the house or if there was settlement or if it's really old...
bloo said on 12/May/18
rob does not eating effect our height?
Editor Rob
It might have some effect on overall hydration and you could shrink to absolute low at night.
tune said on 12/May/18
Rob, I measure 5'9 in the mornings and have measured myself after a 5 hour work shift which involves some moderate lifting and being on my feet the entire time at 5'8.5. I also measured 5'8.5 after 7 hours, 6 working. If I go to the gym for an hour then work 5 hours I am right between 5'8.25 and 5'8.5 6 hours after waking. My absolute low height is 5'8.25, am I a legitimate 5'8.5?
5'9 dude said on 11/May/18
Rob , do you think weightlifting would cause you to lose height at all, or is it just when you start going really heavy for long periods of time , as something I enjoy I wouldn't want to lose any height from it , what do you think ?
Editor Rob
I think long-term and progressing to really big weights and dead lifts puts enormous strain on the discs...it can cause problems with some people, but I don't think moderate weights (unless done poorly) have any effect. It's pushing things continuously over the years that might lead to bulging discs/herniation.
Dave618 said on 10/May/18
Hey Rob. Does a person who is sedentary reach their lowest possible height 12 hours after waking up? I’m trying to be as accurate and honest about my height claim so need to know the lowest I would dip down to.
Editor Rob
They might reach it by 7pm. I wouldn't worry about falling a little fraction under a certain mark at your lowest.

If I fell just under 5ft 8 myself, I'd still go with 5ft 8...if it was 5ft 7.5-7.75 maybe I'd say 'almost' 5ft 8.
scru said on 9/May/18
is 174cm considered an average height in uk?
Editor Rob
The overall average in the UK is still around 5ft 9, so 174 is just shy of it...enough to feel very average if you observe all males, young and old.
portal said on 9/May/18
Rob would you say 7 hours after waking is a good time to measure your height? I had been on my feet working and measured 5'9.5 is this a good claim
Editor Rob
It's rather reasonable to claim a height around 1-2pm.
Nils2 said on 9/May/18
Hey Rob i've measured the same low since i was 18. A week ago i had a long and rough day at work involving lifting. And i slept very little. No matter how tall i stood that evening i measured a full cm under my usual low resulting in a 3cm loss! Has this ever happend to you? And do you think this can happen occasionally to elite sporters and result in permanent heightloss in the long run?
Editor Rob
I've put my body through some physical work days over the years and tested my low...I don't really drop below 5ft 8, even at worse...although a real extreme low after a marathon I'm sure I'd drop a little under it.

1cm extreme low for yourself might be more than you'd expect, but how often do people reach these extremes...not that often.
blade said on 9/May/18
hi rob is it safe to say my low is 5'9.25, I have measured a number of times after going to the gym then working a 9 hour shift on my feet practically all day. I have not dipped below 5'9.25
Editor Rob
Sounds long enough to get your low range, whether you bother adding a fraction if somebody asks your height is another matter.

Some people drop fractions, others round up to say 9.5!
Pnf said on 8/May/18
My recorded height is 175.7. When I wake up usually Im 175.3, in the day Im 174.4 usually and when I go to sleep Im 173.8 on my lowest. My recorded lowest height was 172.7 when I was so sick and tired but that was once and never more. I claim 174 or 5'9 ..is that right height for me Rob or should I claim at 5'8 ?
Editor Rob
You could claim 5ft 8.5 ok.
beaner said on 7/May/18
hey rob would you say an inch is a greater than average lift in shoes/trainers?
Editor Rob
I think an average range (from looking at all this) is around 0.9 inches. 1.4 is a big foowear amount, 0.5 a smaller footwear thickness.

hello Rob, if my height in the morning is 168 cm and at night 166.5 , what should I say my height is ?
Editor Rob
tell people 167cm.
PeterNo said on 6/May/18
Hey rob, my morning height is 168cm after working many hours and at night I shrink to 166.5 cm what should I claim?
zyvick said on 3/May/18
Is it fair to say i am 5'10.5 if i wake at 5'11 and after 5 hours of working a standing job I measure at 5'10.5. Also my absolute low is 5'10.25
Editor Rob
Yeah I think that sound perfectly fair.
justsomeguy said on 2/May/18
I'm like a bit over 5'9 and a half 3/4??? idk the measurement barefoot. Would claiming 5'10 or 5'10.5 too much of a stretch?
Editor Rob
Many folk in your situation would round to 5ft 10...you might also consider 'almost 5ft 10' as an answer.
Zlasku said on 2/May/18
Rob, I am 192cm range out of bed and 190cm before bed. Is it fair to claim 6'3" even though 190,5cm is a flat 6'3"?
Editor Rob
Yes I think that sound reasonable to tell people 6ft 3.
Harry said on 30/Apr/18
Hi Rob. Do you think you would dip a few mm under 5ft 8 if you ran a marathon? I am running one this year, and I am going to measure my height and weight. I will let you know what I measure and weigh before and after. I think it would be fair to call it an extreme low too.
Editor Rob
If I got dehydrated or put under an extreme workout like a marathon it would be interesting to test an extreme low measurement. I doubt I could do a 1/4 marathon these days though!
Ethan188-189cm said on 30/Apr/18
I am 189cm (Most likely 188) and I have recently turned 16, Rob how much taller do you think I will be? It has been stressing me and my GCSE's are in 5 weeks so I need to focus! Thanks, Ethan
Editor Rob
I wouldn't even think about height and focus on exams. I'd say the odds of reachin 192-3cm are quite reasonable, though there's still a chance you might not grow any further.
Zlasku said on 30/Apr/18
Rob, do you think that most people lie about their height?
Editor Rob
I think on average people inflate by about 2cm or so. A good proportion will be honest, but there will be those adding 1-5cm, with more extremes being over 5cm.
Gport321 said on 29/Apr/18
Hey rob, my morning height is 191,3 i
shrink to 189.8 what should i claim?
Editor Rob
I'd claim 190cm
cmillzz said on 27/Apr/18
Rob, most disc injuries won’t have a big impact on height, right? Like I would think maybe a couple mm at most.
Editor Rob
If it is a bulging disc it could be a few mm's. It might effect surrounding discs or your ability to stand as tall as you can, depending on the severity of herniation.
uy5r3 said on 26/Apr/18
Hi rob I measured myself at 5'9.5 after working a standing job for 5 hours about 6 hours after waking is this a fair claim
Editor Rob
That seems an honest claim
Heightfan said on 26/Apr/18
Hey Rob. I measure my height with tape measure, which is taped on the wall. Then stand as tall as possible and measure my height using my fingers. How accurate is this?
Editor Rob
It's roughly accurate, but an object on top of your head should give you a good idea to within a small fraction.
Heightfan said on 25/Apr/18
Hello Rob! You've pointed out earlier that some disc injuries can cause height loss. Did you mean that it stunts one's growth completely or can a person grow after the disc herniation for example. Ketä say that a 17-year-old male faces this.
Editor Rob
You could still be growing, and have an injury which doesn't effect bone growth.
cmillzz said on 21/Apr/18
Rob, a sitting job will still get you down to your low height after 8 hours, right?
Editor Rob
You might be pretty close to it, especially if doing two 4-hour sessions.
Ankit wazerkar said on 20/Apr/18
Sir I m 173.0875 CMS in morning and 171.1325 in evening. So is it normal ?
Editor Rob
It's a typical shrinkage, about 1.8-1.9cm.
boome said on 18/Apr/18
rob would measuring myself after a 5 hour work shift involving moderate lifting be a good time to measure my height?
Editor Rob
You'll be pretty near your low mark by then.
JRC 98 said on 18/Apr/18
Hey Rob...I measure 187cm in the morning and 185cm at night

Is claiming 6'1" correct?
Editor Rob
Sounds quite reasonable to say 6ft 1
Jafarss said on 14/Apr/18
Rob, last night I got home from work and measured 5 mm under my usual low which kinda scared me. However, I measured on a different (wider) wall and I was back up to 186 on the dot, but when I kept measuring on that same wall I was dropping 5 mm under again so I let it go.

Tonight I got home from work and same thing happened again; measured 5 mm under my usual low, then measured on the wider wall and was back to measuring at my usual 186, but when I kept measuring over it I kept coming up 5 mm less again.

Am I measuring too soon after getting home from work, where my spine/head might be a little wobbly to get an accurate measurement?
Editor Rob
A couple of mm variation is common even when remeasuring, as a very slight posture change could account for it...5mm might suggest the other wall/floor could be giving a little less!
Natalz said on 14/Apr/18
Rob, do overweight people shrink more than skinny people since there are more pressure on the discs?
Editor Rob
I don't know if there's any actual research done on it, but from seeing people's variations and weights, I'm not sure there is much correlation.
Ja533 said on 12/Apr/18
Hey rob , I currently lose.bout 9/16" of an inch over the day. I wake up at 184.4 cm and end the day at 183 cm since I have longer legs and a shorter torso does that make me lose less than someone who has a longer spine. Also I recently turned 15 yrs old and I have grown 0.5 inches in the last month. Is it possible I reach 190 cm
Editor Rob
It's less than the average shrinkage, but if your spine is a bit shorter than the average six footer, you'd expect a smaller amount of shrinkage.
Jafarss said on 12/Apr/18
Rob, is it possible to shrink to your normal low on a lazy day around the house? These last 2 days I've dropped only 2 mm above my usual low, even though I've usually maintained a full cm above. I'll admit that I've been at the desk and hunched over for a few hours throughout both days... Is that affecting my loss more than usual?
Editor Rob
Desk work can impact your lower spine, so there are some days after hours at a computer I feel some strain and don't measure much above my low.

Also your hydration levels could effect whether you get to lowest earlier.
Zampo said on 1/Apr/18
Rob,

How far typically is one off his low if after being up for an hour, you walk at a moderate pace for 15 minutes.

Thanks
Editor Rob
They might potentially reach halfway point between morning/evening.
Myself said on 27/Mar/18
Hello Rob) I got diagnosed with 2 herniated discs on the lower back and some bulding on other discs on the upper spine after a magnetic resonance because of my continuous back pain and problems with tingling in my feet...Could that be the cause why my morning height sometimes is variable from 193.7 to 194.1(like today morning), or different laying posture and amount of sleep is enough to explain it?
I was also wondering if with time my discs are getting more and more damaged by this herniation, if when fully healed i would be able to regain some mms and if in case my discs will get such an amount of damage in the next years that considering a disc replacement (with a synthetic one) could be worth it and if it would allow me to regain all the height i would have lost by that moment...

It's strange that in the last maybe 4 months, both my morning and evening heights look to have increased (from about 193,5 to 194 and from 191,5-191,8 to 191,8-192,3); may it have been because of the pull up bar with which i do spine stretching every day? Or i grew up? (i'm still 20) Or maybe the herniated discs did heal a bit? (Or maybe my previous measurements weren't as accurate, although i'm not sure this might be the case)
Anyway, after doing an epidural injection, the doctor told me that it's not good to stretch the spine on the bar for me, to which i was very shocked. He didn't seem to be really in the mood to talk too much anyway and didn't explain why. I don't really believe him, stretching should help to decompress and to straighten up a little my scoliotic lower back, where my herniations are located....
What do you think Rob?


PS: I forgot to add that i haven't seen my extreme low of 191 cm in a long time (maybe because i try to always use all my ab and lower body muscles to mantain a good posture and to reduce strain on the lower spine by supporting it?), the lowest i was lately was 1 week ago, 191,6, after walking all day almost non stop, with hurting spine...
Editor Rob
If you have some herniation or bulging it can effect height, but you seem maybe to still grew in 19-20 a little, or at least manage to measure taller.

If you have some disc problems, then I can understand the Doctor saying to avoid doing bar work.

Some smaller herniations can resolve naturally, but bigger herniation might need surgery.
Jafars said on 22/Mar/18
Hey Rob, I was wondering if you happen to lose mm or even a full cm by just putting on your shoes? I've experimented a bit and when I put on my shoes while still lounging around the house all day, I end up losing a few more mm than I normally do if I lounge around the house all day with being barefoot. Its a bit frustrating!

Also, how much height would we lose by sitting in a car/during a car ride? I remember you mentioned this once but can't remember exactly.
Editor Rob
Sometimes our height will vary 1-2mm in a short period of time, but then that is such a small amount that it's possible to measure 2mm different by simply standing slightly better than before.
rlvp85 said on 18/Mar/18
Hi Rob, I have a question for you. I always thought that my height was in the range 180.5-178, but during the last months I've been doing exercises for correcting posture, particularly anterior pelvis tilt correction exercises, I think now I am in the range 181.5-179. I've checked it multiple times. In fact, when I am at home and relaxed, I've measured myself between 179.5-180, while if I am active on my feet, I've measured myself between 179-179.5 Do you think these exercises have helped me stand better, hence I regained a cm of my true height?
Editor Rob
For some people, these type of exercises might enable them to reach maximum standing potential...improving their overall posture so they can measure a small fraction taller.

I'd go with the height you are currently measuring.
Rem said on 12/Mar/18
Rob, what is the explanation that you give to the fact that i only shrink 0.4 cm at most from morning to night? I wake up at 176.5 and go to 175.1 at 10 pm, after playing a football match por example. What is more, after an hour or so of waking up i shrink a full cm.
Editor Rob
That sounds a very low shrinkage, the lowest I've read. Maybe your discs are genetically better at retaining their water content than others.
urel said on 5/Mar/18
Hi rob, would it be safe to say I have hit my low after working out and working a standing job for 9 hours involving some heavy lifting too that I have hit my low mark? I dont think I would creep any lower if I measured before bed after just lounging around after work?
Editor Rob
I think you should be right around your lowest range after a 9-hour day job involving some moderate activity.
urel said on 3/Mar/18
Rob would you say a 7-8 inch deodorant can will be sufficient to measure my height
Editor Rob
Under that length and it might not hit the topmost part of your head (assuming you are facing the wall to do your measurement).
Markode said on 1/Mar/18
Rob, does bad footwear contribute to height loss throughout the day? My consistent/daily low is 184 cm, but last year there was one situation where my friends jokingly made me wear these really squeezed/tight shoes of a shorter friend of mine and wanted to see how long I lasted. I wore them for about 40 minutes and they absolutely killed my heel (they were burning), and I remember when I took them off I was shorter than a 179 friend of mine, who was in 2.5 cm - 3 cm shoes MAX. He would have only gotten to 182 in his footwear compared to me barefoot at most.

I clearly remember his eye level was noticeable higher than mine when looking and talking at him. I was absolutely shocked to be honest. Basically it felt like I lost maybe 3 more cm than I ever do. I don't know if that sounds crazy or not...
Editor Rob
If they somehow effected the way you moved and caused more strain on your discs, only then would I say the footwear might contribute to a little extra loss than with a more comfortable sneaker.
5'9 dude said on 1/Mar/18
Hi Rob, just curious to know does a guy say who is 5'9 like me and a guy who is 6'0 shrink less as they age because of spine length ect. And if I'm in good health, exercise regualary , will i start to lose height at around mid 50s and if so how many millemeters? ,

Would appreciate your response , thanks!
Editor Rob
You might make it to 50 without anything noticeable, but by 60 you could have lost something like half inch, some might lose 1/4, others 1 (or more even).

Keeping yourself fit and healthy, with good nutrition is beneficial.
ManKo said on 28/Feb/18
@denimal

No way, he is at least 6'1 today, look at this picture with Arnold, if he is just 6'0" then Arnold is way shorter than the listed 5'11.

Here another picture of Bill with Zydrunas, who is 6'3"

Bill is still very close to 6'2 nowadays.

ManKo said on 11/Feb/18
Hello Rob,

why do you think some guys lose way more height than others? Some guys such as John Cena (40 yearls old) and Bill Kazmaier (former world strongest man and 64 years old) seems to be as tall as when hey were younger and they surely took steroids and deadlifted /squatted huge amounts.

Bill Kazmaier is NOWHERE near as tall as he once was. He's lost at least 2" in height. He still has good posture, but he's nowhere near 6'2.5"-6'3" (his prime height). He seems to be in the 6'0" range at best today.
Kalle M??tt? said on 27/Feb/18
Wow, I didn't know you're Scottish! :)
Anyway, thanks for your work. I've been interested in human heights myself as what I'm going to look like when I'm an adult.
lg said on 27/Feb/18
do you think by going to work and sitting down majority of the day won’t effect height loss much? I’m at work and I’m normally sitting down and not walking much and I seem to not lose much height from my morning height
Editor Rob
I do think prolonged sitting in same type of chairs can cause some issues, which is why taking regular breaks and even the odd little touch toe/touch ceiling stretch during the day may help.
jk1409 said on 25/Feb/18
My grandfather started shrinking when he was 75, a combination of age and neck problems which absolutely destroyed his posture. He was 6'0" in his prime and he is 5'8" now at age 80. He still has the 'aura' of being a tall man however. He's a Scotsman like you, Rob.
Editor Rob
4 inches is a lot to lose, you'd expect about 2 inches or so for a 6ft man at 80, but unfortunately injuries can take their toll.
boii said on 25/Feb/18
Hi Rob, i was wonedering. Sometimes i wake up being a solid 171-172cm in the morning and im 170.2cm. If i stay at home and lay down all day i realise that i hardly lose height compared to when im out majority of the day. Is it because im not doing much activity?
Editor Rob
Activity levels definitely effect how much we shrink. Laying down regularly will certainly keep you closer to your morning height!
Lit in da club said on 22/Feb/18
Rob, in your view - do weight exercises preserve height or cause one to lose height?

I lift heavy weights about twice a week and I believe that over the last 10 years, I feel about 1/2 inch shorter. I used to be 5'11" and now closer to 5' 10 1/2. No squats or deadlifts though.

I have also read that weight bearing exercises, including strength training, help you avoid height loss.

Can an inversion table help?

My wife is 5'7" and is a high heel girl, I can't afford to lose any height.
Editor Rob
I think regular use of inversion or decompression might be helpful as we get older. Weights in moderation may also help, but once you start going very heavy and putting excessive strain on your joints, that's when long-term heavy lifting could contribute to greater height losses.
KevinKevin said on 18/Feb/18
Hey Rob, I have a question. When I do evening height measurement, the height of the body varies from 182-182.5, there is no problem. But i am looking at the my family and my friends them, they seem to be getting taller. My height same but I feel that my eye level height is decreasing. How can people look at me taller than they used to be ?
Editor Rob
That sounds a bit bizarre. Maybe you are lowering your eyes a bit more or your posture isn't as good as it used to be.

Also, some people can have balance issues which might mean they find it harder to tell objects above or below their eyelevel (line of sight).
Luker said on 15/Feb/18
Rob, do you consider a person's max height from just staying at home all day cheating? I wake up at 188 on the dot, and settle at 187.2 an hour later, and can literally stay there as long as I'm at home all day practically doing... well, not much haha. But on a day out and about and after work (where there's a lot of lifting boxes and using my back) I drop as low as 185.8 - 186.3.

Would you take my max height (187.2) into account when say finding the middle ground/median or again, is that just cheating?
Editor Rob
It's not cheating, it's just not your low range. A man who is active and on feet for a job could be a 1/4 inch taller on a day off and not having as much strain on his back.

This is why I always go with 5ft 8 1/8th as my height, because it is my working height - up early, on feet a lot and I'll get to my low height meeting celebrities quicker.

If I was meeting them in my house I'm definitely more 5ft 8.25 range! 😇
Jimony said on 15/Feb/18
Hey Rob! I'm 178 cm in the morning and 176 or so in the evening. Should I claim 5'9" or 5'9.5"? I usually go with "5 foot 9 and a half" when asked about my height.
Editor Rob
It's a reasonable enough figure. Saying 5ft 9 is a slight round down from your low. Some folk won't be bothered about that and just say 5ft 9, others similar to yourself might get measured at 11am and find they were 5ft 9.5 and go with it.
Canson said on 14/Feb/18
@Jared: I have a 6’6” and 6’7” friend. Both lose under an inch from what they tell me. The taller measures 6’7 3/4-7:8 out of bed and 6’7-6’7 1/8 at night the other 6’6.75-6’6 7/8 and 6’6 at night. They lose what I lose and I’m a bit 6’4.25 (6’5 in the morning). Weight is a huge factor as well
Jared said on 14/Feb/18
Hey Rob,

Just a question-- What would you say is the average height shrinkage (first thing in the morning-to-night) for someone who is 6'6" at night? Would it be around 3cm on average? So, if someone measures 198cm at night, would they normally measure about 201cm in the morning?

Thanks.
Editor Rob
I think it is far likelier to shrink over an inch when you get into 6ft 3+ territory, but you'll still find people whose discs don't compress as much as you'd expect.

If the average is close to 2cm (1.8-1.9) then a 6ft 6 man you'd expect has a greater chance of losing 2.5-3cm range.
Simone said on 13/Feb/18
@Rob Hi Rob, after 15 hours I'm around 173cm and when I wake up I'm around 175,2.
Would you say I'm about 174,5?
Editor Rob
I would put you more in the strong 5ft 8 category, although some people who wake at 5ft 9 and shrink closer to 5ft 8 might go with the average and say 5ft 8.5
jeja said on 12/Feb/18
Hi Rob, would you say wireless electronic stadiometers are more accurate and reliable than traditional ones ? I was considering buying one of this kind
Editor Rob
There are low budget stadiometers and high-end expensive ones - you would think if they are manufacturing them and selling them for many hundreds, they'd damn well make sure they were very accurate ;)
ManKo said on 11/Feb/18

On the other hand, guys such as Arnold (70 years old), the Rock (45 years old) or Hugh Jackman (49 years old) seems to have lost more height even though they did not deadlift/squat as much as Cena or Kazmaier....or guys like Clint Eastwood, he lost a lot too even if he didnt do heavy weightlifting.

do you think in the long term heavy weighliftin contributes to height loss or it is something related with your gentics?
Editor Rob
Long-term punishment on joints can accelerate losses once over say mid 40's.

Some guys might make it to 50 with minimal loss, but after that, they start to suffer with ankle/disc/knee/hip issues. Small problems in one disc can also effect others.

Charles-Guillaume said on 9/Feb/18
Hey Rob,

I've been trying to approximate my lowest possible (healthy) height. Do you think that a brisk three hour walk in the early afternoon (without taking a seated break, to the point that my thighs hurt from exhaustion) suffices to arrive at a normal or maximum low? In the morning I can measure 181-181.5 but I am unable to fall asleep on my back so perhaps that measurement could be increased. After the walk I am 179.5. Claiming 180 should be perfectly reasonable, no?
Editor Rob
Yes, a 3-hour walk would get you to usual low range at that time.
Emil12345 said on 8/Feb/18
Hey rob
I am 183,8 in the morning and 181-6-182 in the evening.
What do i claim to be?
Editor Rob
Seems ok to go with 182cm as your height.
Maxwell said on 5/Feb/18
Also a couple more questions. Is there any way to shrink less throughout the day from morning to evening? I want to stay as close as I can to my morning height. It’s very annoying that we lose height throughout the day.

And lastly, why did I shrink 4 mm more than usual today. I didn’t do anything that was too strenuous on my back, so what’s the deal with that? Maybe I need to strengthen my back muscles too...
Editor Rob
Keep yourself well hydrated, and avoiding heavy lifting/rotation might mean you are slightly better off...but we are talking tiny amounts.

You could maintain a taller height with a few short 15 minute lie downs during the day, like every 3 hours, that way you might be a 1/4 inch over your low for most of the afternoon/evening.
Maxwell said on 4/Feb/18
meant sit ups, not squats LOL. Thanks Rob.
Editor Rob
Sit-ups are a decent exercise for posture improvement.
Maxwell said on 3/Feb/18
Hey Rob, do you think doing core strengthening exercises like planks and squats can increase height by a little bit? Like perhaps by half an inch?
Editor Rob
It may help your natural standing posture, but maybe not your actual height (beyond a tiny amount)...by natural standing, just the way you hold yourself - you'll find it easier to stand closer to your measured height.
Alex3001 said on 3/Feb/18
Hi Rob!
What time of the day do you recommend to get meassured? I mean, if I usually wake up between 7-8 am, which would be the best moment to meassure out my height so I can claim an accurate and honeat meassure?
Editor Rob
mid-day is a reasonable time-frame.
Animus said on 1/Feb/18
How big a difference can hydration level make on our measured height? As much as, say, ¼ inch? Let's leave out extreme dehydration and focus on what can happen for most people on a day with little fluid intake.
Editor Rob
It could take several days to reach a really bad level of dehydration, such that your body is using up fluids from the soft tissues like discs...a dangerous level might mean an extreme of 1/4 to 1/2 under your usual lowest.
Canson said on 30/Jan/18
@Kendel: that’s a huge stretch saying 6’6”. You’re legit 6’3 1/2 maybe weak 6’4. I’m actually a bit taller at my low a few mm under 194 at my low and I could claim 6’4 or 6’5 since I’m close to 196 (195.7 or .8 out of bed) but still claim 6’4. I guess I could say 6’5 but don’t see the point. I would never want to be 6’6” tho even if I were to claim that as a shoe height as that’s just too tall imho. My view of 6’6 is someone who is 197.5-199 at a low and 6’7”ish in shoes which puts you in an uncomfortable situation tbh
diofs said on 29/Jan/18
Rob I am 175.26cm when I wake up and hit a absolute low of 173.355. Do I claim 5'9?
Editor Rob
Personally I wouldn't claim 5ft 9, but some people do go with their morning height.

Maybe I'm not a fan of stating a height that you fall under!
JamieBoy said on 26/Jan/18
Rob; in regards to height recovery; would laying on your side while watching a movie recover any mm? I always thought for your height to recover you had to be flat on your back. Thoughts?
Editor Rob
Yes, it should still allow your discs time to rehydrate a little.
ManKo said on 23/Jan/18
Rob what do you think about exercises such as hanging from a bar or using an inversion table / inversion boots to strech your back?

Also, what do you think about suplements such as gluscosamine, could it help to rpevent height loss?
Editor Rob
I recommend using a bar for decompressing the spine and just arm strengthening.

Inversion might help long-term with retaining a slightly taller morning height.
Akshay176cm said on 22/Jan/18
Rob,I am 177.6 cm when I am out of bed and in afternoon around 1 pm I am 176.2 cm and at night generally if fully hydrated then I am 175.9 cm. So,Rob can I claim 176 cm?
Thanks Rob
Editor Rob
I'd certainly say 176cm was an ideal claim.
Dragos said on 21/Jan/18
Hello Rob.I've been following your website for a while now and i wanted to get an opinion from you.I measured myself at 169.2 cm out of bed in the morning and then again after 12-14 hours at 167.5 cm.My job job consists both in sitting and standing.I was wondering what height should i claim.Should i go with 168 or 167 since my evening height is in the middle of both .Sorry for my english and thanks in advance.
Editor Rob
I think you should say 168cm.
Hans said on 18/Jan/18
Hey Rob, i‘m 176,7cm at Night after working (i have a standing Job and i‘m on my feet all day). I also noticed that i don’t shrink under that even if i go to the Gym or on a Night out after working. So is it save to consider that as my low? Also how many hours of standing straight on your feet do you Need to Hit your low? On my best mornings i‘m 178,7-178,8. so which height am i? 177cm? Thank you!
Editor Rob
If I were you I'd claim 177cm and not think anything of slipping a couple of mm under it...nobody will notice.

Rob, My out of bed height is 193,3 cm what would you say ı am? 191,5 or 6 ft 3,5 ?
Editor Rob
I think claiming to be 6ft 3.5 is very fair, I'd go with that

@Hambubger,
I'm basically same range as you I'm 186.3-4 in the morning and at night I'm 184.3cm what would you say I am?

Rob, is normal sometimes being shorter than usual? Like 0.5-06 cm shorter? I noticed this thing sometimes.
[Editor Rob: everybody has what could be described an 'extreme low'.

This might occur through dehydration, excessive exercise that puts strain on the spine beyond your normal daily activities.

For some people it might be only 2mm difference, with others it may be as much as 6-7mm less than what they usually measure at their low.]

You are a "solid" 6'1". I myself am a "weak" 6'1", morning 186 night 184. Don't worry about halves and quarters because they are arbitrary because of height compression during the day.

Interesting thing about height loss during day - I saw a chart which shows height loss during day for slim, medium and obese people. An obese person loses a bit more height than a slim person during the day - 2cm vs 1.8cm or so. But the most interesting part was that while the obese person loses almost all their height by mid-morning, the same amount of height loss is not experienced by a slim person until afternoon. A medium sized person is somewhere in between but closer to the slim person.

So if you are comparing the heights of two people, and you can't compare them straight out of bed, you should take weight into account. Case in point, Obama and Trump. They seem very close in height, but Obama is very slim and Trump is somewhat heavyset - so I'd wager confidently that Trump gets out of bed marginally taller but the advantage is gone by the time he finishes breakfast.
