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.

Hey Rob, when I my check my eye height at night 11 pm ,standing nice and tall ,it's 150.1 to 150.3 cm's, but when I stand in a forced straight posture ,my eye level can go upto ,150.4-150.5 cm to 150.6 cm's. Does that mean I'm atleast 161 cm's to 162 cm's at night?
Editor Rob
sounds like you'd be at least 161 range, possibly between the 1 and 2

Measured myself again this morning 190.5cm I use a level and wall with a tape measure. My absolute low height at the end of the day is 6'2 1/8" but most of the day I hover around 6'2 1/4"-6'2 1/2". I just measured my eye level after being up for a hour and its 5/10 1/8" or 178.1cm. I'll measure my eye level at the end of the day and let you know. Also, im 280lbs

@Chinedu some idiot claimed I was 5’11 and stood me next to his 6’1 mate, who I had 2 inches on. It goes both ways cause I’m normally guessed as 6’3 or 6’4
6'3 Julian said on 21/Sep/20
@RJT 6’2.5 is my extreme low. I’m probably just under 6’3 most evenings. Also we measured how far I was under the 6’6 doorframe and it was 3 inches. This was at 1pm so it’s about how most people view me. I often get guessed as being 6’4
Chinedu said on 21/Sep/20
@Christian 6'5 3/8"

Reminds me of a guy I met before the lockdown. He was claiming 6ft tall but standing close to him, he was shorter by 1.5 inches. When I told him I was just over over 6ft, he tried convincing me I was 6'2 and not 6'. I made sure i got him measured that day so he could atleast lie next time with the truth in mind 😁
RJT said on 20/Sep/20
@6'3 Julian

Well I'm not doubting you but personally I'd prefer to measure mine standing against a measuring tape or stadiometer to gauge my height down to the closest 1/8" or milimeter in metric. I meant 1/4" or even 1/2" will be hardly noticeable at a glance or if based only on estimation against object but under measurement tape or stadiometer, trust me it will seem like such a wide gap.

I'm also like you at bedtime I measure 6'2.5" but I claim about 6'3. Personally I'll only claim 6'3 if I'm never under 190.5cm at late afternoon or fall slightly under it only at bedtime or during extreme low case, but it's just me. Ultimately it depends on the person after all.

Rob my out of bed height is 186.4cm and my height goes to 184.8cm within 5-6 hours out of bed and before going asleep it is 184.4cm what height should I claim
Editor Rob
Fair for a 185cm claim
Christian 6'5 3/8" said on 20/Sep/20
Same like how I often get guessed taller than I really am. Like Rob said, people inflating cause them to inflate others.
Ehsan Jabar said on 19/Sep/20
Hi Rob I'm 20 years old and my out of bed height is 186.3cm however within 5 hours of waking my height drops to 184.8cm and before bed it lingers around 184.4-184.5cm. i seem to get to my low pretty quickly.

Is my height tall? And is it fair to say I'm 6'1
Editor Rob
It might be fair to say about/almost 6ft 1
Russell Chung said on 19/Sep/20
If my night time height is 172.2cm or 172.3cm how tall would i be in the morning?
Editor Rob
174 up to 174.5 range is quite likely
Maxwell Johnson said on 19/Sep/20
Rob I am 5’9 exactly out of bed. What height is realistic for me to claim?
Editor Rob
Many would go with the height they measure - so at 11am you are probably 5ft 8.5, so it's fair to claim it.
Miss Sandy Cowell said on 16/Sep/20
Oh no! I have to go on tiptoe now to see if there's a teabag in my mug when I've boiled the kettle! 🍵

It's little giveaways like this that told me I'd lost height during the lockdown. They say what goes up must come down, and that's fine when applied to weight gain 👅, but I'd like to think that the opposite applies to height loss. Yes, it's out with the glucosamine and stretching exercises all the way for me now, until I'm back up to 61"!
Tom Jones said on 15/Sep/20
Rob, I have a morning/evening height of 186.5/184.5cm. What height do I claim metrically and can I claim 6’1?
Editor Rob
About 6ft 1 is a fair claim
Chinedu said on 14/Sep/20
Good evening Rob.

It just amazes me that with an evening height of 6ft and a quarter. A lot of people (who are also height conscious) ALWAYS guess me at 6'1.
I've never been guessed my real height talk less of being guessed under it.

I don't have a small head and I wear flat shoes often.

What do you think might be the reason. I will really like to know?

Is there anything you think I might be doing that's affecting my appearance physically. I will like you to please tell me so I can continue doing whatever it is😁

Editor Rob
It can be that some people inflate their own height so are basing your height off their own inflations.
6'3 Julian said on 14/Sep/20
@RTJ I was standing under a doorframe at my dad’s house, he made a comment on how I’m nearly as tall as it, and we measured how much shorter I was. I was 3 inches shorter than the doorframe, which was 6’6. That puts me at 6’3. I go with that claim because it was measured at 1pm
RJT said on 13/Sep/20
@ 6'3 Julian & @Nicholas Graham

You measured in stadiometer or with measurement tape with object on tophead against wall or just estimation based on pic?

Y'all got over 177cm (5ft 9 3/4) eyelevel at afternoon or night? I feel like we're similar height.
Holend said on 12/Sep/20
Hi rob I want to ask you , do you consider over 5'5 or 165.6 barefoot very short for male like noticeably short or just short and normal in global, I want reality from you it doesn't hurt. 😊
Editor Rob
It's short in many countries, but in some big ones, like India, it's within the average range
6'3 Julian said on 12/Sep/20
What would you list me as? I measure 6’2.5 right before bed and am 3 inches under a 6’6 door frame at 1pm (hence why I claim 6’3). I also weigh about 212 pounds at 9.4% body fat if that helps
Editor Rob
If you looked that height in person or with others you would get it, but if you passed for nearer 6ft 3 maybe you'd get 2.75 or 3...it ultimately depends what a person looks.

Their claim is interesting of course, especially if they state fractions!
Mark Philips said on 11/Sep/20
Hi big Rob. I wanted to ask you my real height. I am 175.4 exactly in the morning and at the night right before I get in the bed I am 173.3. What do you think I should claim ?
Editor Rob
Technically if you said 174cm to people, that would be a reasonable figure.
Joe Dumars said on 11/Sep/20
Hi Rob my height in the morning is 176 cm and night before bed is 174.5 cm. Fair to call myself 175? My height seems to be catching up after giving up steroid cream for eczema... I was measured 171.5 in the morning a year and half ago. Doctors should really warn about the side effects of corticosteroid usage during puberty, I have read that it even stunts height growth and bone age. Scary stuff.
Editor Rob
I grant you the power to claim 175 👍
Nani said on 9/Sep/20
Hi rob my height in the morning first thing 167.3 and at 10 pm on a active day 165.3 but when I lay down in bed for 15 or 10 minutes my height is 165.8
So whats the height you will give me on this web site I mean my real height!
Editor Rob
You might get the kind of middle figure of 166cm, but it also depends how tall somebody looks.
Shermarke-Somalian said on 8/Sep/20
Hey Rob I have recently been measuring my height and what I have found out is I seem to lose 3.5cm quickly during the day,,My maximum height is 187.5cm but shrink 3.5cm and my ultimate low is 1.84cm barefoot.I wake up every morning measuring 185.5-186-186.5cm and only seem to recover 1-2cm upon waking up.at home I always seem to be 1.84cm barefoot and with flip flips I am exactly 1.85cm,,with shoes on I am exactly 1.86cm so what heights should I be claiming.???
Editor Rob
I'd go with about 185cm if you are asked your height.
Nicholas Graham said on 8/Sep/20
Hey Rob, I measured myself everyday this past month. Right out of bed I am 190.3-190.4cm and only a few times I was 190.5-190.6. My low height everyday was 188.4 and maybe 188.3. On a heavy day of walking and activity I get as low as 188.1cm so I lose between 2-2.3cm a day. In fact today I woke up measured myself around 10:00am I was 190.4 and after 10 hours of walking around my downtown area not relaxing When i got home i measured 188.45cm. Can I average 190.4 and 188.3 and tell people I am 189.3cm/6’2.5’’? Also on another wall in my house my max morning height was 191cm and my low was 188.6cm so if I average these 2 i get 189.6cm. Checked these with my level and they both were exact level.
Editor Rob
Going with average range like 189cm seems fair for you.

Some guys I've heard say six two/three and I take it as they lie between those marks, like yourself. If you go with 6ft 2 and a half, that's a good figure to say.
jayp said on 6/Sep/20
would someone who has a active job for example a construction worker lose more height throughout the day or not lets say they lose 2cm or average amount from out of bed to before bed would this work cause more or not?
Editor Rob
Yeah, any job like construction, building/trades could get you to your low quicker and on many days to absolute low range.
Jv said on 4/Sep/20
Hi Rob,
I’m 18 and I’m 173.6 in the morning and 171.6 before bed
Since 5ft 8 is 172.7, can I still claim 5ft8 or is that wrong ?
Editor Rob
About/almost 5ft 8 isn't a bad claim...or 172cm if giving metric
HA123 said on 3/Sep/20
Hi Rob, I measured myself at around 2pm as 187.6cm. Am i ok to claim 6 ft 1.75 as my official height?
Editor Rob
yeah I'd go with that mark
6'3 Julian said on 3/Sep/20
Rob, does obesity cause height loss? I’ve lost 20ish pounds this year (went from a chubby 232 to a muscular 212) and I feel a lot taller. Is this just me having weird perception or did it actually make me grow?
Editor Rob
In very large weight gains, it may effect height, but 20-30 pounds I doubt has any difference.

Maybe the act of improving fitness results in better posture and slightly taller measurement for some people?
6'3 Julian said on 2/Sep/20
My dad is 52, 174cm/5’8.75 exactly and weighs 95-97 kilos/210/214 pounds. Taking this into account, how believable is his claim that he was “5’10, sometimes almost 5’11” in his prime?
Editor Rob
Unless he's been a wrestler or a worker that has done in his joints, it seems hard to believe at that age he's shifted over an inch
RohanBanerjee said on 1/Sep/20
Hi editor rob hope you are doing well.I have been facing some problem with my height especially so say I am 5 ft 11 some say I am just 5 ft 11.30 ..but I checked myself right out from bed 6 ft little bit more very less after four hours it shrinks a little bit around 5 ft 11.65 after then goes to around 5 ft 11.40 at noon and in the evening 5 ft 11 inches even before going to bed Ian 5 ft 11 inches now sir rob what will be my exact height what I am going to say what's your opinion I do need your suggestions. Should I just go with my evening height or my average height
Editor Rob
Many people with your stats would go to a physical and get measured near 5ft 11.5 before lunch, so it's fair to just go with that.
Chandrakant kunwar said on 31/Aug/20
My morning height is 178.7 cm, evening 177.6 cm and night height before bed is 176.7 cm then what is my true height
Editor Rob
Personally I'd just go with 178cm
Rory said on 28/Jul/20
Rob, if my Dad at age 69 is a strong 5ft11 and is pretty fit and has a good diet etc, how tall would you guess he was in his 20s ? To me in the last ten years his height hasn't really changed I don't find,not noticeably anyway. Posture has worsened but still looks similar to how he always did when he stands fully.
Editor Rob
Maybe almost 6ft if he has remained fit and reasonably healthy. You are lucky if you get to 69 with just half inch of height being lost.
Pena said on 28/Jul/20
My mornimg height is 179-179,5 and evening height 177,2-177,5. I claim to be 5'10 or 177,5cm.
Editor Rob
about 5ft 10 is fair
Chinedu said on 28/Jul/20
Good morning Rob. I'm 20 years and I measure 185 - 185.5 out of bed but at my low I never ever go below 183.1. In the evening like around 5pm am around 183.5.

What would you claim if you were me? And will I be considered tall?
Editor Rob
I'd call you a tall guy in most countries.
Say I had not much interest in height, and got measured at the Doctor's - I'd likely be near 184 and then claim that figure.
slothee said on 27/Jul/20
Rob, the CDC has 5’9 5/8” (176.9cm) as the average height for a 20 year old American man. Do you think this is inaccurate due to many measurements taking place in the morning? Would the real average (afternoon/evening) height be lower (e.g. 5’9 1/4-3/8” (176cm)) instead?
Editor Rob
It might represent a before mid-day overall average. If you go by afternoon, it might be more 5ft 9 3/8ths
Lawrence Clark said on 26/Jul/20
Rob, my dad who is 61 years old measures 185.5 at a low. What would have been his peak height in his 20s and 30s? 6’1.75?
Editor Rob
188 isnt out of the question entirely, but 187 is likely
FiveEightJake said on 25/Jul/20
Rob what's the best way to hold onto your height as you age or is it purely genetic based? I couldn't find a video where you talk about minimising height loss, is it just keeping active and stretching?
Editor Rob
Keeping active and including some weekly exercising, regular daily walking, simple stretching (just to keep supple) and decent diet are all factors I'd do as I age.

Plus I'd avoid cigarette's completely.
RJT said on 24/Jul/20
Hi Rob, I took pictures of me measuring with tape and would like your honest opinion about it

Click Here (this one the tape was maxed at 189cm or about 6'2 3/8)

Click Here (this one the tape was maxed at 189.5cm or 6.2 5/8)

Both pics were taken minutes from each other, about 4 hours after woke up.

Excluding hair, do I clear at least 6'2 1/2 in your opinion?

Might not be standing at best cause I was holding tape with left hand and phone at right hand, but did hard to stand straight and not tilting my head.
Editor Rob
Considering 173 is about end of nose, yeah you could be a 6ft 2.5 range guy.
Jeddy said on 23/Jul/20
Hey rob if I wake up at slightly under 192cm and go to be at around 189.5 cm roughly can I claim 6ft3 ? Is that a normal height loss for a 19 year old ?
Editor Rob
Yeah, that's within typical range of morning/evening you'd expect and saying about 6ft 3 seems a fair figure.
Mark O' Connor said on 23/Jul/20
Hi Rob WIth my range 191-189cm (With the max I get 191.5cm and 189.4cm on a good day), will I be at the same level as someone like Routh and Welling?
Editor Rob
I'd expect you would look similar range in person if near those two.
Caris said on 22/Jul/20
Hi rob just wondering if you have flat back syndrome does this mean you gain height ? And if fixed would there be height loss ? Thanks
Editor Rob
If exercises are done which target the posture/curvature issues then I think some height could be regained through correcting the problem. It might not be a big amount though.
Derick said on 22/Jul/20
Hi Rob!

I wanted to know if i possibilty stunted my growth. I am turning 19 next month and I am 176 cm but my body portions are off. I have short legs and a small head with small hands and feet.
I do have a history of bad health since I was a kid. I was diagnosis with IBS since I was 13 and I never really went outside and do excersices although I did have a good diet and sleep. My dad is 6 feet and my mom is 5ft 2. So if i didnt stunt my growth, could it be most of my height was determined by my mom's genes or i truly did stunt it and is it still possible for me to grow at this age?
Editor Rob
Based on parents, 5ft 9 range is probably within the kind of range a Doctor might have predicted.

However, there are some factors like diet/environment/ill health during childhood and teen years that might inhibit (even if only a few cm) our genetic potential.
Jozhtuna said on 22/Jul/20
hey Rob, my morning height is 181.5cm, after playing intense basketball for 2 hours in the morning, and walking through the rain lugging a few items to go home, my height is 179cm in the afternoon. Just wondering will my height creep back up to the 180cm mark after resting, and is that height shrinkage normal? thank you!
Editor Rob
If you take a glass of water and eat a meal and relax for an hour on your sofa, I would expect you would creep into 179.5 range at least
RJT said on 22/Jul/20
Hi Rob, I measured again and again and it seems I made small mistake, my tallest at morning is at 190.2cm or 6'2 7/8 because my eyelevel's distance to the top of my head is 12.5 cm or almost 5 inches. I asked my brother the other day at night and I measured exactly 188cm or 6'2 flat, my eyelevel's height was 175.5cm give or take at the time, so my eyelevel's distance to my top head is 5 inches. My eyelevel at the time I measured 190.2cm at morning was 177.7cm give or take (Higher than 177.5cm but lower than 178cm) I did hard to stand and look straight, not tilting my head.

I'm usually between 189.2cm (6'2.5) to 188.6cm (6.2.25) after afternoon and my absolute lowest is at 188cm (6'2 flat) at night. But that might be my lowest because I also measured 6'2.25 often at night.

I want to ask that you put Brandon Routh and Welling at 6'2.5 while you put Affleck at 6'2.25, what separate Routh/Welling to Affleck? Is that what their 'average' height's estimation would be after afternoon?

So after looking at my stats, would you categorize me at guys like Welling/Routh or Affleck?
Editor Rob
You might be similar to Affleck in person...guys like Routh/Welling could still hold near 2.5 at night, whereas I didn't think Affleck could hold onto that range.
Mone Kamishiraishi said on 21/Jul/20
Hi Big Rob,

I am 181.9cm after 15 hours being awake, can I claim 6 feet?
Editor Rob
I think saying 6ft is ok for you, maybe 'about 6ft'
Hoddis2199 said on 21/Jul/20
Hey rob!morning measurements are 182.1cm and around 180cm before sleep,a smudge over it.can I claim it to be 6ft?
Editor Rob
Personally I wouldn't claim it. 181cm might be fair.
Me.T said on 21/Jul/20
Hi Rob, I breeze over 5’11” quite comfortably in the morning, closer to 181 than 180, five hours after I wake up I’m about 179.5 so a little bit above 5’10.5” (though I have been measured 180.5 at about mid-day by a doctor before). I live a very active lifestyle (Muay Thai and callisthenics) and sometimes get as low as 178.4 in the evenings before bed, which is still Over 5’10”. When people ask my height I say I’m about 180 or 5’11”. Should I lower this, am I being unreasonable in this claim/what would you put me as on your site. I notice a lot of the time guys who are a cm or so taller than me claim 6’1” and Try to tell me I’m 6’0”, obviously I’m a way off that barefoot but I still feel dishonest saying 5’11”. Thanks.
Editor Rob
Claiming 5ft 10 is a little round down. 'Just over' 5ft 10 covers the kind of range you are for a decent portion of the day.

I'd never adjust or fake my own height to appease people around me who inflate theirs.

If someone asked my height, I'd say it like it is.
Bobby Green said on 19/Jul/20
Hey Rob after commenting recently I decided to measure again and saw that my low after about 16-17 hours of walking and after sports is about 180.5 cm (usually 181). Also, I was wondering whether measuring the “height” of ur eye level with a tape measure and then adding the height u have from the eye to the top of head (with a ruler) would be accurate? For me it’s been pretty accurate however I wanted to check with you.
Editor Rob
It's always best just getting the object on top of our heads to take a reading
Mone Kamishiraishi said on 19/Jul/20
Hi Big Rob,

I don't usually reach my absolute low height after exercising (i.e 10km run, playing football or tennis for 2 hours). However, I do usually reach my absolute low height if I did not sleep well last night (or if I only slept for less than 3 hours), if I am sick, and also if I spent the whole day walking in my house the whole time (barely having any time to sit down and rest, only meal times perhaps). Is this common?
Editor Rob
You might find in some situations (ilness, lack of sleep) that hydration levels could be less than ideal, so you might find yourself hitting your absolute low range.
Texm said on 17/Jul/20
Hi Rob. Great site!..Am 181/2cm in the morning and last thing at night i am 179.6..just over 5ft 10 and a half. 4pm i am 180cm. I've always claimed 5ft 11 but now think i should claim 5ft 10?? Whats also weird and what i've noticed is so many inflate their height. Was standing chatting to a guy at a party and he said he was 5ft 10 and i had at least 2/3 inches on him..he said you're 6ft aren't you i said no 5ft 11..he said you cant be. We both had on flat shoes
Editor Rob
Don't claim 5ft 10, that would be too low.
Maybe you could go with 'almost/about 5ft 11' if you want to indicate you fall under it.
Simon01 said on 15/Jul/20
Hey Rob I usually wake up at around 6'1 or 185.5 but sometimes measure as low as 182.5 granted this is an extreme low and once I've sat down a bit I'm usually back up to 183.5 but I'm just wondering how or why it seems to fluctuate so much?
Editor Rob
On couches/sofas, sometimes the spine can be more relaxed and recover a few mm's.
RJT said on 15/Jul/20
Hi Rob, I want to report that after many times measuring myself at the morning, the tallest I've gotten was 189.7cm or just tiny bit under 6'2 3/4. After few hours or so I've shrank to be about 188.6cm to 189.2cm so around 6'2 1/4 - 6'2 1/2. My lowest at night is just above 188cm mark. Can I still say 6'2 half with these stats?

I've also noticed that due to my bad posture, if I stand in my usual relaxed posture (Hunched posture), my eyelevel is only around 174.5 cm or under 5 ft 9, and if I stand tall my eyelevel is around 176.5cm or 5 ft9 1/2, that's a big 2 CM difference! At morning my eyelevel is 177.5 cm or around 5 ft 10.

I also noticed that I have what looks like anterior pelvic spine, where my pelvis is rotated forward, which then made my back look curved and affect my posture badly, I look like this even after forcing my posture to stand tall. (Left one)
Click Here

It is said that human can regain about 1/2 inch to 2.5 inches if we can fix it depend on how bad our pelvic tilt is, which possibly could make me well over 6'3! As you can see from my previous statement, I regained 2cm or 3 quarters of inch just by correcting my posture, which is already bad due to anterior pelvic tilt.
Editor Rob
Maybe 'over 6ft 2' or 'just over 6ft 2' is a claim you might make?
lam johnson said on 13/Jul/20
Rob what height would you give me

7am (first thing) - 6'3.5/75
10am - 6'3.25
12pm - 6'3.15
2pm - 6'3
5pm - 6'2.9/85
7pm - 6'2.85
10pm - 6'2.85/75
Editor Rob
Fair to call you a 6 foot 3 man.
Shazz said on 13/Jul/20
@rob, to be extremely accurate using a cylinder and mark against a wall in my socks, i am precisely 5”11.656. Exactly at my extreme low.

I dont think its fair for me to be going around saying 5”11 when im literally close to an inch over it at an extreme low measurement. Wing span is around 6”5 as well and am very long limbed; im not built like a 5”11er imho.

What do you think though? Is it ok to say 6 ft? Im positive at a more fair time of measurement id be like 5”11.75+
Editor Rob
Very few would round down to 5ft 11...maybe some females might do it though.
Shazz said on 13/Jul/20
Hey @rob, if im 6”.5 out of bed, sometimes even a tad over by a mm or two, and 11 hrs being awake right after some intense heavy lifting and walking i am around 5”11.6, can i claim 6”?
Editor Rob
Say you got measured 11am at the Doctor's...you are likely almost 6ft then so it would be fair to just say about 6ft. If you went with low, then 5ft 11.5...
Sam89 said on 13/Jul/20
Hi Rob, trust u well. I have a straight out of bed height of 172.5cm and a final bedtime height of 170.4cm after a full day at work. What height should I claim? Thanks
Editor Rob
171 might be a height to claim. Personally I wouldn't go with 172, although if you went with feet/inches maybe 5ft 7.5 is also a reasonable height to tell people.
Bobby Green said on 12/Jul/20
Hi Big Rob, I’m a little over 183cm in the morning and 181 after an active day. What would my height be on this website and I wanted to ask if it’s ok to round to nearest inch when stating height (in my case 6ft since I’m around 182.2 at 2pm).
Editor Rob
yeah, you might end up at 182cm
Jackrjrrjkrjk said on 11/Jul/20
I'm also a distance runner and just turned 18. Do you think I have any more growing? If so, how much more?
Editor Rob
At 18, the percentage of those who gain height drops off quite sharply each year till early 20's when it's a tiny percent. Whilst there's still a chance to gain at 18, I think I'd take any further growth as a bit of bonus.
Luiz said on 11/Jul/20
Hi Rob . Considering this .
Out of bed (8 am) : 176.8
Before bed (12 pm) : 174.7
Most part of the day my height varies between 175.2 - 175.7 cm .
Do yo think claiming 176 cm is a lie?
Editor Rob
it's fair enough going with 176, it's more a 9-12am height range for you.
Jackrjrrjkrjk said on 11/Jul/20
Hi Rob,

Out of bed, I stand 6'3". My low is 6'2.25", and between them; I stand 6'2.5"—6'2.75".

Is claiming 6'3" unreasonable?
Editor Rob
6ft 2.5 might be a good figure to go with, or 'almost 6ft 3'
E.a.m said on 10/Jul/20
Hey Rob.I'm 170 cm in the morning and I become 169.5 in the evenings. At night i'm 168.5. What height should I claim?
And what height you would put me in this site?
Editor Rob
169cm is a fair claim and listing for you.
Marouane 90 said on 3/Jul/20
Mr. Rob, I want to know my height in the morning. I am 190.1 centimeters long, and 187.9 centimeters in the evening. On average, my height is between 188 and 188.3. Can I say that my height is 6 "2'1/8
Editor Rob
I'd just go with 6ft 2 range, some guys might say 'over 6ft 2' if they measured say 6ft 2.25-2.5 at 10-11am which you may well manage.
RJT said on 3/Jul/20
Hey Rob thanks for keep answering my question(s). It's too bad that I didn't find your website earlier...

I was 182cm near 6ft already at 14 in middle school, but now at best I'm only 6'2 1/2 (Only grow 2 half inches) at afternoon, pretty disappointed because most people around me at the time commented I'd grow well into 6'4-6'5 range.

I think I have a a bad posture and horrible body flexibility, for example I can't even touch the floor from standing position and can't reach my legs too in sitting position. I've had this issue ever since elementary school afaik and I'm not fat, about 190lbs.

Do you think it affects my measured height or even my true potential maximum height? Now I'm 27 and haven't been growing for years. Maybe if I could fix my posture and flexibility, I can gain half inch or so to become legit 6'3?

Thank you Rob.
Editor Rob
It would be interesting to do a stretching routine. Maybe over a month, improve flexibility and posture and then see if you can measure slightly taller as a result.
It would show you did indeed have some 'hidden' height in reserve.

I've read quite a bit from people doing yoga/pilates over the years that they seem to have measured a fracton taller after taking that up...
Rem said on 30/Jun/20
Hi Rob. I worked on my spine doing atretchings during this last couple of years, and i have managed to grow 2.5cm from 18 to now that i am 22. Do you think that having scoliosis may have afected my height previously? I mean now i get a good posture not only measuring myself, but in every moment of the day. I was about 172 on the nose at night when 18 yo and now i am 174.5 at my lowest (it depends on the day but i never go below that mark).
Editor Rob
Maybe your routine helped you achieve a final little boost...and also the benefits of stretching for posture as well.
RJT said on 30/Jun/20
Hi Rob I have question, I have measured myself at night many times using measurement tape, in photo it looks like my night height is only at 187cm mark but when I actually max it to 188cm on the tape, and then I did the salute pose from 188cm mark, it always touched part of top of my head! I did hard not to look up and stand straight. What's strange is that no matter how many times I tried, my eyelevel at night seem to be at 175cm mark, maybe 175. 5cm at best (Which seem low for my height) . Is it fair to say I'm at least 6'2 1/2 at afternoon and maybe even 6'2 3/4 at morning?
Editor Rob
I would be surprised if standing tall you weren't 6ft 2.75 out of bed.

Might be worth trying to check one day, if you do it within 30 seconds of wakening up, you'll catch your tallest height.
Fio said on 29/Jun/20
Hello, Rob, probably a really dumb question: when I've stood up/walked around for a decent amount of time and measured my height, it is (let's say after 8/9 hours of being awake) 6'3.85 or bang on 6'4", but when I go sit down and re-measure (after an hour or so), I'm a touch over 6'4" (like 1/8th over). Is that normal? Always thought sitting decreases your height.
Editor Rob
Walking and being upright probably got you to a low range, then your discs recovered a bit.

Some sitting positions can put more pressure on our spines than others...on a couch is less taxing than sitting upright in a chair, which is less taxing than sitting in a car seat (with all the vibrations on our joints) for a couple of hours.

Asu said on 27/Jun/20
Hi rob i hope ur doing well.
My morning height is usaully between 181 to 181.5cm depending on sleep and my normal low is 179.6cm but after a long run or weight training i can hit extreme low of 179. What height should i claim and if i was on the site what height would you have me listed at?
Editor Rob
It always depends on how somebody looks as to what they get listed.

You might fall into almost 5ft 11 category
Lawrence Clark said on 27/Jun/20
Rob, my morning height is 186.2cm and night height 184.2cm. Can I claim 185 or 6’1”?
Editor Rob
Maybe go with almost 6ft 1
G.Heinrici said on 26/Jun/20
Hi Rob. I shrink 1inch during a normal day. Can I reduce it to 1-1.5cm?
Editor Rob
Unfortunately it is something that is harder to alter, though some people have said glucosium sulphate tablets seemed to help their evening height a few mm.

It's impractical for most people to have a small lie down for 20 minutes every few hours...
Rimbaud said on 24/Jun/20
Hi Rob, i read that you said a measurement five or so hours out of bed is fair to claim, does that include time sat down or does it have to be five hours on your meet? Cheers
Editor Rob
We still can lose height sitting down...it places some strain on our spines, some chairs more than others. But yeah, just 5 hours of being up is a fair range.
Brobro said on 23/Jun/20
Hey Rob, there’s a significant curve in my low back when I stand up as tall as I can due to hyperlordosis. If I fix it can I gain some height. I could send more info and x ray if that’s allowed. Thanks
Editor Rob
Might be worth reading up on the topic and seeing any videos on youtube, as if you can correct curvature (or improve it) you might measure a bit taller.
Man of culture said on 22/Jun/20
Hey rob, what do you think about laying down measurement, how much of an error i can expect from it i constantly get 5ft 11.25 at 6 pm at night and 6ft or 6ft1/8 in morning, at home I've been measured a lot of different readings due to uneven wall and surfaces and in doctors i've been measured 182,181,180 plz tell me my exact height claim

And plz tell me how much inch of error can we get if our wall slope looks slightly like this [)]
Editor Rob
I would always state height when measured standing up, although it is interesting to see if your lying down height is slightly longer. Potentially you could get a fraction more, but it depends on how you stand for a measurement.

I stand well for a measurement, so my lying down height isn't that much different. I did an old video.
TL said on 20/Jun/20
Hi Rob, my height out of bed is around 184.7cm and my night height is at 182.7cm what should i claim? 183?
Editor Rob
If you go with 183, not many are ever going to think you're not that tall. Personally, with those stats I'd claim 183 too.
Solid work Rob said on 19/Jun/20
Hi Rob. Why do women shrink more? Cheers!
Editor Rob
osteoporosis is a major reason.
Latasha said on 18/Jun/20
What's the difference between standing tall or not?
Editor Rob
It depends.

If we are talking about height measurements, then sometimes a person will stand well, but could still stretch up another few mm to their maximum height.

If it's a natural pose compared to a measured (standing tall) pose, it might be a fraction or even in some cases an inch or more for those with poor natural stances.
Elder said on 18/Jun/20
Hi Rob, if I measure at 171.1 5-6 hours out of bed, what would be my low?
Editor Rob
Could still fall a couple mm shy of 171, but it's probably fair to just claim 171!
RJT said on 18/Jun/20
Hi Rob, I measured max 189 at morning around 4.30 am and then did another test at 6.00 am and I shrank to 188cm. Did another test at 6.30pm and shrank again to 187cm. What I found is that the eyelevel height also shrank by about 1cm each test. You think its normal?

What height you think I should say my height?
Editor Rob
Well, I think it's natural that as you fall a cm in height, your eyelevel drops 1cm too.
Miss Sandy Cowell said on 18/Jun/20
⭐ You know you've lost height when, every time you go to the kitchen, you know you'll have to go on tiptoe or stand on something to reach cups you used to be able to reach without any trouble at all! ⭐

Sharanya said on 17/Jun/20
Hi Rob. I know I posted here last December but just another quick question. I recently measured myself at night (9-10pm) and I stood 166cm barefoot. What height would you end up putting me on this website (12-1pm)?
Editor Rob
5ft 5.5 probably
Nik Ashton said on 17/Jun/20
@ Greg - Cool idea! 😎💡!
Lawrence Clark said on 17/Jun/20
@Rob, if someone measures 184.3cm at 22:30 at night what would they get on this site and what should they claim?
Editor Rob
It always depends on how they look against others, at least those who you have a good idea, but their height claim is given consideration.
Greg said on 17/Jun/20
@Rob that would be cool average visitors height you should run a poll. Maybe even do it average visitors height by name or something that’s sounds like a good idea! My guess would be that the average male celeb heights visitors height would be something like 5’10 range.
Lover_thorn3 said on 15/Jun/20
Is it bad to not shrink much? My morning height is only 181cm and my before bed height is still Just barely 180cm

Also do we know if women shrink more than men im a girl and i only shrink like 1-1.1cm
Editor Rob
Shrinking 1-1.1cm is on the low end of shrinkage range. Near 2 is common...3cm is like 1-1.cm, more uncommon.
Alice Bennett said on 15/Jun/20
Rob, if I’m 169.5 cm in the evening around 9 pm, which height do you think I should claim?
Editor Rob
Just go with 170cm
Andy5'91/2 said on 15/Jun/20
Is it normal to lose a full inch? I wake up at 5’10.5 most of the day im about 5’9.6 and before bed im 5’9.5
Editor Rob
Jenny is closer to losing a full inch than myself. The average is closer to 1.9cm from the studies I've seen. Would be interesting to see what the average was for visitors to this site, as many would have tested their morning height.
idkwhy said on 15/Jun/20
I’m 176.7cm at 2-3pm-ish. How tall do you think I am in the morning?
Editor Rob
If not over 178cm range I'd be surprised.
John Paul said on 28/Mar/20
@Big Rob, if I wake up first thing in the morning as 5'9 and 1/8.. what would you put as my height on this site assuming i lose an average amount?
Editor Rob
You might end up at 5ft 8.5
Damdam said on 27/Mar/20
Good morning, Rob,

I have a question about the size of the morning and the evening, does our morning size affect our evening size?

By that I mean that we have two sizes in the morning, whose maximum size we reach after a good sleep of 8/9 hours which can be 1/4 inch higher.

Does this mean that if I get up to my maximum size my evening size will also be 1/4 inch higher?

For example:
I lose 2 cm a day
I get up after a good sleep at 170 cm and go down to 168 cm at night
So on a bad day, I get up at 169.5 cm and go down to 167.5 at night?

Is that how it works, rob?
Thank you
Editor Rob
From what I've measured, I don't think the extra hour in bed effects the night height too much.

I've measured the same range at night on good/bad days before...however, for some people they may well find a bit more variation than I do, especially if they shrink 2.5-3cm in total from morning to night.
Edouard said on 27/Mar/20
I'm the author of the previous comment. Is it possible that I shrink about 3 cms because I usually drink daily only one or at most two glasses of water? Thanks rob for all that you do for us
Editor Rob
I would recommend drinking several more glasses of water a day.

I suppose it is possible your total shrinkage could be close to 3cm from highest in morning to lowest at night.
Edouard said on 26/Mar/20
Hi Rob. I'm 179,5 out of bed (my peak), while my absolute lowest is 176,5 before bed. In your opinion is fair to claim 178 cm or should you go with 177 cm?
Editor Rob
You have a greater range of shrinkage, so saying 178 is right in the middle.
Ultimately you should go with a height you are comfortable saying, be it 177 or 178.
Alistar said on 25/Mar/20
Hi Rob,
I'm 176.5cm when I got out of bed and 174.5cm 11 hours later. Should I claim 176cm as my height?
Editor Rob
I would personally go with 175
Mark O'Connor said on 25/Mar/20
@Rob, I measure 187.5 at 5 p.m is still fair to claim 6'2?
Editor Rob
It's a little round up, but not too much. Not like you are 186 and rounding up to 6ft 2!
The destroyer said on 20/Mar/20
Hi Rob, 4 hours after waking up I measure 182.4cm, majority of the 4 hours I’ve been walking a lot, what’s my low height before bed, do you think I manage to stay 182cm as my low or do you think I dip a little under 182cm?
Editor Rob
You might still fall a bit under 182, maybe after some more physical activities or workout.
Boy68 said on 19/Mar/20
@Big Rob, my max morning height is 182 and my lowest is 179. What height should I claim
Editor Rob
180 might be a fair figure to go with.
Lumia said on 19/Mar/20
How many hours of sleep can we return to the highest height?
8 hours? 9hours?
Editor Rob
About 8-9 is a good amount of sleep to get near our maximum morning range.
Vick said on 17/Mar/20
Hi Rob,
I’m 5’11.5 in morning and 5’11 at night. Would it be far fetched if I said something like “close to 6 feet” or should I be more accurate and say “a little over 5’11”.
Editor Rob
'Just over 5ft 11' is something that could fit your range. I wouldn't say 'almost 6ft' though.
Tiiger said on 16/Mar/20
Hey Rob, my height before bed after a long day is 181.3-181.4 cm. I've been claiming 181 cm so far, but almost everybody thinks I'm taller than that is it fair enough for me to claim 182 cm although I don't feel right claiming a height that I can't reach for some time in a day?
Editor Rob
Claiming 182 seems fair enough.
Leon Evans said on 13/Mar/20
If my height is 181cm in evening is it possible my morning height is 183cm?
Editor Rob
I'd be surprised if you weren't around that mark out of bed.
Timberlake said on 12/Mar/20
Why can't I recover to my highest height after 7 hours of sleep after exercise?
Editor Rob
Your hydration levels might effect your disc height very slightly, plus 7 hours might not be enough for full recovery. 8-9 might gain another couple mm.
Linke said on 6/Mar/20
Rob, how common is it to lose height in 20's and 30's?

Also, how common is for a person to lose over 3 cms in a day?
Editor Rob
Some lose over 3cm in a day, but I believe the minority.
Losing height in 20's is down to injury or disease or long-term bad habits that cause curvature. But I still think extremely rare.

30's the chance increases, but really again I think it's a tiny minority. 40's though it will increase, especially in women.
Nora said on 5/Mar/20
Why did my height become shorter for four or five days after doing exercise hardly?
How do I get my height back?
Editor Rob
If you have caused a slight injury, that might be a reason. If your hydration (water intake) is ok, then maybe I'd think some small injury could be possible.
Kennie said on 5/Mar/20
Hi Rob,
I measured myself today around after 1 hour of waking up: 184.5. What do you think my height right out of bed would be?
Editor Rob
Potentially fall to 183cm range
Mikel yang 123 said on 3/Mar/20
Hey rob I’m 180.2 cm before I sleep, I claim to be 181 cm y’all, is that right?
Editor Rob
It's fair enough to claim 181
Jude Meters said on 3/Mar/20
Hi Rob, I got a strange question to ask you, when I measure myself on the wall in my room and the kitchen wall, I measure 181 in the morning and 179 at night on both walls. But when I measure myself on the living room wall, I measure 179 in the morning and 177 at night. I’d say that the two walls that I measure taller on are more accurate, but do you know why I measure a different height on the living room wall?
Editor Rob
Sometimes it can be tricky to determine if the wall/floor has a slope. But, one of your walls seems to have something like that, to give such a difference.
NathanielClancy said on 2/Mar/20
Hi Rob do you know if people with flat feet lose more height throughout the day. I wake up around 186cm, but I feel as though I lose quite a bit. Was wondering if you new anything about it?
Editor Rob
I wouldn't expect any difference
Olegg said on 1/Mar/20
Rob, if we have two bald people standing next to each other and the other person is 1 cm taller than the other, do people notice the difference?
Editor Rob
1cm can blend in and be harder to spot than a full inch. However, most people if they were asked to look more closely, might be able to see the person who is taller.

However, say you had a 5ft 5 person looking at two bald men, 6ft 2 and 2.5, the difference will seem smaller than if you asked a 6ft 5 man to check who was taller, just because their eyes are much lower and the difference then looks smaller as a result.
Jonny Clewett said on 29/Feb/20
Hi rob, if im 182.2cm at 11am whats my average height?
Editor Rob
182 might be your average, you could still go to 181-181.5 and wake up at least 183 range, bit more even.
Jereth Jordan 179 said on 28/Feb/20
I'm 179 cm within the first minute of the morning, fully rested. I usually go with that lol
Carlodcx96 said on 26/Feb/20
Hi Rob, why it is not possible claim the morning height? I read some articles that you should measure height in the morning
Editor Rob
It is a valid measurement of our height, however most people (vast majority) do not get measured out of bed, nor for physicals are they at their highest height. So fitting in, claiming a height after being up several hours works seems reasonable.
Joseph175 said on 26/Feb/20
Hello Rob, if a person wakes up at 179.4 cm and goes to bed at 177.4 cm. What height should he claim?
Editor Rob
Saying 178cm in this situation seems fair to me.
Stefan said on 25/Feb/20
Hey rob,

Straight out of bed i am 181 cm but before bed i can be as low as 178.5

I was measured at the doctors at 180 around 10-11 in the morning once.

What height would you put me at in cm and feet?
Editor Rob
You could go with 180 or 179, I suppose it depends on yourself what you prefer to say.
Dany75 said on 25/Feb/20
Good morning Rob,

I’m 1m69,5 in the morning and 1m67,5 in the evening, so I lose two centimeters in the day, I want to be honest and feel good, saying 1m68 is okay?
Editor Rob
Yes, saying 168 is perfectly fair.
Shermarke-Somalian said on 24/Feb/20
Hi Rob Before I was 187.7-187.2 cm barefoot out of bed and 185.2-184.2 cm before bed that was before.Now I suddenly measure 188.2 cm barefoot out of bed and 186.2 cm before bed to check,I went outside and played some football and which causes people to shrink and when I came back I measured and I was still 186.4 cm barefoot in the evening which is very shocking I am not writing this to brag about it I just want to share with you what I did I would drink many packages of Whole milk before bed and sleep many hours sometimes and I would take multivitamins after meals.I am currently 24 almost 25 in 1 march I really hope I am 188.2 cm barefoot in the morning which means my average height is 186-185 cm during the day
Editor Rob
If you measured yourself in the same wall/floor, then it could be a case of reaching your current height at 24!
Joseph william said on 23/Feb/20
Good morning Rob.
If my morning height just after I woke up is 183.4cm and 6 hours later it becomes 181.5cm (measured in the doctor office after a long travel) and my absolute low is 181cm which height should I claim? is it fair if I claim to be 182cm ? is that means I'm gonna be the same size as Daniel Wu if I stood next to him?
Editor Rob
You would look quite close to Wu, although at times he can pull off 6ft.
I think claiming 182 for your height is fair enough.
Juvia said on 21/Feb/20

I get up at 178.0 and after 9 hours my height is 175.8~176.0.

How do I declare my height?

Is it the same as measuring height at home vs. hospital?
I mean hospital electronics or infrared equipment.
Editor Rob
If you measure at 11am, you might be 176-7 range, so you could claim either figure.
Carlodcx96 said on 20/Feb/20
Hi Rob! If I am 186,5 on morning and the evening 184,5 I could claim 186?
Editor Rob
It's a more early in the day figure. It's really up to yourself, as long as you aren't saying 188cm or something like that, 186 or 185 I'd go for.
Anton_Blanco said on 16/Feb/20
Hi, big Rob!
Do you agree that if my height 30 seconds out of bed - 186,2 and before bed (after long hard day and gym in the evening) - 184,0 then I am solid 6’0,5” and almost 6’1”?
For calculating weight and ideal proportions in bodybuilding I need to know the exact height. What value do you recommend using as my height for sport?
Thank you!
Editor Rob
In sport, I would just go with 184cm, then nearly every other competitor will not think you are shorter than your claim.

You are a comfortable 6ft and half inch guy.
5ft 11 7/8 in said on 14/Feb/20
What would be fairer in your opinion, 182 or 183?

Early Morning: 6ft 0⅝in - 184.5cm
Early Morning: 6ft 0½in - 184.0cm
Late Morning: 6ft 0¼in - 183.5cm
Afternoon: 6ft 0in - 183.0cm
Evening: 5ft 11⅞in - 182.5cm
Early Night: 5ft 11¾in - 182.2cm
Late Night: 5ft 11⅝in - 182.0cm
Editor Rob
Either is fair, it depends on what you feel comfortable saying.

182 is the lowest and if you claim that, you know you don't shrink less than it. 183 is the middle ground, the figure that if you didn't care about height and were at a 11am appointment you'd measure and claim.
jayp said on 14/Feb/20
Been up just over 11 hours today out of bed at 7am and measured just after 6pm but just been at home doing some house duties chores and studies etc so not too much and measured 3+ times at 174.5- 174.6 what height am I?
Editor Rob
Fair enough saying you are 175cm
Vsquad said on 13/Feb/20
Rob. I just got home at around 6:00pm after being awake since 5:00am.

My feet have been burning all day, especially on the train ride home which was 1 hour and I was standing the whole time (and looking down at my phone). I measured myself immediately when I got home and I was below my usual 183.8 low mark... I never really dip below that but I don't know what happened today.

Like I said, my feet have been burning all day - they always burn after enough walking, I don't know if I have it worse than others or not. Or if it contributes to losing height.

I'm also lifting weights regularly even though my spine posture is bad (pelvic tilt). Am I making my spine permanently deformed like that if I keep lifting? Is it making me lose even more height?

I'm so bummed after measuring.
Editor Rob
Situation could have made you dip just a little under typical low...I still think claiming 184 is fine though.
I do think improper weight lifting form could raise the risk of some disc issues, so I'd always be careful and make sure you know what you're doing when lifiting is correct and not damaging.

Yeah I think about 6ft 1 is fine, because he comfortably clears it out of bed.
NathanielClancy said on 12/Feb/20
Hi Rob if I’m about 184cm at about 4 o’clock in the afternoon, what is my morning height do you reckon?
Editor Rob
Could be 186cm range, maybe a bit more
brodie said on 10/Feb/20
hi rob i just turned 16 and im 180.2cm fresh out of bed and 178.5cm at night how tall do you think i could be. My dad stopped growing just after 18. he was 179cm peak and my mother is 165cm.
Editor Rob
If you hit 184cm, it would not be a surprise.
Triplescrew said on 10/Feb/20
Rob, how long would you have to nap to regain a noticeable amount of your morning height? 30 minutes? An hour?

Let's say it's the afternoon and you've already pretty much hit your low. You lay down and get a solid 20-30 minute power nap in. Do you gain anything appreciable there or are we talking millimeters?
Editor Rob
an hour could get you 7-8mm, maybe some folk get 1cm or so from that.
Joeshmoe said on 1/Feb/20
Hey Rob, do most people usually lose any more height after being up for 10 hours? Like, would being up for a whole day be any different?
Editor Rob
Not much, talking 1-2mm maybe, but if they did some exertion at 6-9pm they could end up towards an extreme low which might be 3-4mm less than typical low.
Hanne said on 26/Jan/20

Wow, have you grown a centimeter since you were 24? How tall were you when you were 20/21?

What did you eat or did you exercise to make you taller?

I’m 20yo now and I’m 177.9-178.1(out of bed) lol
I wanna become legit 5’10 ( ・᷄ὢ・᷅ )
BroBroD said on 23/Jan/20
If my afternoon height is 180cm, how tall am I 181 or 182cm
I’m just about 184cm in trainers in the morning on a good day I’m 184 cm sometimes I’m 183cm, 179cm comes up to my forehead
Editor Rob
You're an honest 5ft 11 guy. Some would claim 180...if you turned up for a 10.30am physical, you might be nearer 181, so it's not wrong if you claimed that figure either.
George10 said on 22/Jan/20
Hi Rob,
if i measure 179cm right out of bed and lowest i go is 177.5cm(I used tape to measure my height) at the end of the day what height should i claim? Can i use my mornong height and say i'm 5'10.5" or just go with 5'10". At the end I'd like ask another question. How can i preserve my current height as long as possible( I'm 21) ? Thank You in adavance!
Editor Rob
The vast majority of people lose height as they age.

There are some things I might consider as you get older, building habits like simple 3-5 minutes of daily stretches or keeping active playing some sort of sport. Some height loss is due to injuries/surgeries or genetics...also your diet when young can determine how strong your bones are and that may be another factor in how much you lose.
Alex Katch said on 22/Jan/20
Hi rob, i'm 184.5-184.8cm at the morning and after 6 hours i'm 182.9-183.0cm and after 18-20 hours i'm 181.8cm, and sometimes 182.2-182.3cm, how tall am i?

Rob, what height would you list me if i was a celebrity from those below?
5ft 11½in = 181.6cm
5ft 11⅝in = 181.9cm
5ft 11¾in = 182.2cm
5ft 11⅞in = 182.6cm
6ft 0in = 182.9cm
Editor Rob
5ft 11.75 might be a listing for you, I'd say 182 range, but for a portion you are also 183.

Depends how you personally feel about claiming 182 or 3, I'd go with whatever you feel confident saying.
Maria Anne said on 22/Jan/20
Rob, How tall should a person who is 177 cm tall get up?
178? 178.5? 179? What do you think?

And how many hours to get up to measure height is more accurate?
Editor Rob
There's no universally agreed time to measure. Personally I think if you go with 5-6 hours out of bed that is reasonable.

177cm, I'd say they should be 178.5 out of bed
Lukas said on 21/Jan/20
Hi Rob, I am 182.5 to 183 in the morning. My absolute minimum after 18 hours of being awake is 179.5-180. Can I reach 6 feet. I am 20 years old. My father is 189 and my mother is 165.
Editor Rob
The chances are lower once you are into early 20's of any noticeable growth, but of course some folk still have a late spurt.
Maybe if you found out whether your father or anybody in your Mother's side had any growth at 20-22, it might be an indication you aren't done.
Baws said on 20/Jan/20
Hey, boss

I am 25 and managed to gain a centimeter

I was just 178 in the morning just after waking up, 177.5 an hour later, 176.5 in the afternoon, 176 in the evening and just over 175 in the night. I was also 24 then

I am now 179 when waking up, 178.5 moments after, 177.5 in the afternoon, 177 in the evening and 176.5 in the night:

Time before after difference
first thing 178 179 +1
morning 177.5 178.5 +1
afternoon 176.5 177.5 +1
evening 176 177 +1
night 175 176.5 +1.5

Thoughts on why would this happen and is there any more possibility to grow? I wanted to be at least 180 just after waking up, 1 cm can't be too much to ask? I measure a lot and with precise methods
Editor Rob
If you improved a cm, that might be a kind of limit, unless you kept going and doing more work for another 6 months - then report back if you managed any further gains, would be interesting if you kept going.
jayp said on 19/Jan/20
Hi rob if I’m 5ft 9.25 out of bed what would you say is my height I think I might be 5ft 8.75
Editor Rob
It could fall to 8.5 range at teatime
Yoko said on 18/Jan/20
Rob, how tall am I?

Morning height: 177.9-178.1
After 9 hours: 175.7

176? 176.5?
Editor Rob
You could claim 176 and nobody would bat an eyelid at it, even 177 is nearly in the middle of your range. Claim what you feel comfortable saying.
Shermarke-Somalian said on 15/Jan/20
Hey Big Rob.

I measured my height this morning Normally,I was 187.2 out of bed and 185.2 before bed that was 2 weeks ago,Now this morning i measured again and i couldn't believe that i was 188.2 barefoot out of bed and 186.2 now at evening and night,I am truly shocked right now and i am currently 24 maybe i measured wrong this whole time and didn't know about it.According to the height of both my parents my height was estimated between 185-189 i am now 188.2 cm do you think that i could get to 189 cm.??
Editor Rob
If you can repeat the test on another wall, that might help to know if you are really 188 first thing or not.
Cyril said on 14/Jan/20
Hey Rob if my morning height (in 1 minute after bed) is 181,5 and evening height after hard work is 179,5 what should i say about my height for you opinion? My mom is about 168 and dad about 180. Am i tall???
Editor Rob
You are tall in some countries, upper average in others. I think calling yourself 5ft 11 is fair.
Connor Gannon said on 14/Jan/20
Hey, Big Rob. Two quick questions.

1) After finding your site a few months ago, I've improved my posture. I seem to have "gained" a little. I'm 6' 3/8" right out of bed, and a whisker under 5' 11 7/10" before bed. How would you list me? Would it be reasonable to claim 6'?

2) I bought myself a paper of Adidas Ultra Boosts. They give me 1.19". How much height do sneakers typically lose from use?
Editor Rob
All depends on the material used for the sole and insole. Some don't lose much (1mm or 2), others could drop 3-5mm.
Deep Purple said on 13/Jan/20
Rob, can you say me how many height someone loss after 1,2,3,4,5,6,7 hours out of bed? Please, i want compare me to the average loss height during day.
Editor Rob
I used to have a graph showing this, but I can't find it this moment!
Alex Katch said on 12/Jan/20
Rob, i'm 185-185,5cm (6ft 1in) at morning barefoot, and 183cm (6ft 0in) at the night, with parents 172-173cm (5ft 8in) mother and 169-170cm (5ft 7in) father, am i tall, very tall or medium?
Editor Rob
You are a tall guy, should never have to worry much about it during life.
Melted said on 11/Jan/20
Rob, when I measured myselft first thing in the morning i get 188,2cm mark. And after 16 hours of hard work I get down to 185.5cm on dot. What height shoud I go with and in your opinion, where would you list me?
Editor Rob
If you're going by metric, saying 186cm seems fair to me.
A1 said on 7/Jan/20
Hi Rob, if you were walking around a lot during the 6 hour period once you come home are you at your lowest height?
Editor Rob
Yeah, walking about for 6-7 hours will get you near your low.
thatmanoverthere said on 6/Jan/20
Hey Rob, typically how much height do you lose after being up for 8 hours? Also, If I am 182.6 cm after this long, what height should I claim?
Editor Rob
1.5 range I might lose for 8 hours of being active. You could still claim 183 if you like. 182 might be your real low height. If you claimed that, most people would never question your height, and many might think you are very modest!
Tony Cao said on 2/Jan/20
Hey Rob, I’ve done a few tests with the tape measure and got 5’9.5” every time. Measurement was done barefoot in the evening with back ,heels, hips and head touching the wall. I now remember at the doctor’s office, I was measured while facing the wall but my toes weren’t close to touching the wall. Could that be the reason why I was mismeasured by one inch and a half at the doctor’s office?
Editor Rob
The device itself could be the reason for the mismeasurement...if you are getting 5ft 9.5 with own tape measure and on a different wall/floor, then I'd go with that as your height.
Antonio_20 said on 1/Jan/20
Happy New Year, Rob!
Let me ask you this question: how can I increase my height by 1-1.5 cm in 20 years? Can the body at that age grow a little bit by itself? All the same, half an inch is not so much.
Thank you!
Editor Rob
Some people could improve posture through exercise/stretching and remeasure 6 months later about 1-1.5cm taller. However, if you have already quite good posture, it's difficult to add anything.
Tony Cao said on 31/Dec/19
Hi Rob, I’ve been measured at the doctor’s today at 5’8” but I suspected something was off. I had the nurse remeasure me and she said I’m 5’10.5”. Three years ago I was measured 5’8.75” at the same office. I’m currently 22 years old. All measurements were barefoot in the afternoon. Is it possible the nurse mismeasured me? I knew that I gained height for the last three years and I also own a tape measure at home to verify my height. Every time my friends my brother and cousin measure me at home on a flat wooden surface the measurement always comes out to a flat 5’10”. I don’t know who to trust.
Editor Rob
For such strange variations, I would check your own height. Buy a tape measure and do a few tests yourself to see what you get. Too much variation, something is off for sure with the Doctor's office.
Charles33 said on 30/Dec/19
I think this question might have been asked a lot of times. When I wake up I measure at 187cm and before after a long day I measure 185cm before bed. Which height should I take?
Editor Rob
You ask 100 guys you might find a bit of variety with their claims.

I feel if you turn up at the Doctor's, got measured 185.8cm they'd mark you down at 186 in your medical file, so it's perfectly fair to claim that figure. Other guys might like going with maximum measurement or others don't like claiming heights taller than their low.
Xhavier said on 28/Dec/19
Measured myself earlier this year and recently over an 16-18 hour day. My morning height was 198cm or 197cm, midday height was 195.5cm or 194.5cm, and night height was 194.5cm or 193cm.

So I am curious, just for fun, how tall would or do you consider me, or if this was one of your celebrities, what would you list them at and would you have a peak height or not?
Editor Rob
WOuld entirely depend how you looked with others or in person, so it is possible you could get 6ft 4.5 but considering your big variation in height from 7am to 10pm, a 6ft 5 listing might also be possible.

It's a very big variation, really rare to have more than 4cm
Alto said on 27/Dec/19
Hello Rob! I am really curious so I hope I could get an opinion from you. My lowest height I ever fall to is 181 cm and I never fall below that so I was wondering what height would you list me if I was a celebrity. Also I am 17.5 years old and my dad is like 171 cm and my mom is 167 cm so is there any chance I might become an even 6 foot
Editor Rob
You could end up on 5ft 11.5
Kabir said on 27/Dec/19
Hey Rob,
I measured myself at 184.5cm after being 16hrs+ awake,I had been roaming around from afternoon to late evening,(6-7 hrs),my morning height is like 188cm.So basically I have two questions 1)Is 186cm(6'1.25") an honest claim for me if not then what should I claim? 2)Is it possible to reach 6'2"(I am already 19),but my puberty is not completed i think as my facial hairs have not completely grown like an adult.
Editor Rob
185 would be a claim at which nobody would really question your height...but then, since you are also 186 for a large chunk of the day, that is a fair enough figure, especially since you have a bigger than average shrinkage from morning till late evening.
Grenda said on 27/Dec/19
If I am 5”11 and a third and 5”10.75 in the evening. Could I claim a flat 5”11?
Editor Rob
In your case, I think it's very fair just to claim 5ft 11 or 'about 5ft 11'...
Pablo Pablo said on 26/Dec/19
Hi rob, About a month ago I fixed up my posture by stretching and measured at 177.5cm in the morning and 175.4cm at night. But after not stretching for a couple weeks I've started to slouch again and my night height has considerably shrunk back to 172.7-173.4cm which was my old previous night height before fixing my posture. Consistent with my ulna (forearm) length of 26cm. Did my stretching only temporarily boost to my height? Considering I'm still 177.5cm at morning why am I shrinking so much at night.
Editor Rob
You might have maximised your posture and need to keep up the routine to maintain that top measurement...there's no harm in making it a routine again, as it can be beneficial to health.
Grenda said on 26/Dec/19
I’m 181.3cm in the morning. What would I be in the night
Editor Rob
Maybe in 179 range
Shermarke-Somalian said on 25/Dec/19
I measured out of bed 187.2 cm barefoot and before I used to lose about 1 cm now I seem to shrink 2 cm which gives me evening and night height of 185.2 I always seem to be 185.2 barefoot and with shoes I am back to my morning height of 187.2 cm so can I claim 1,87 cm between am I tall for my height I am Somali immigrant born in the Netherlands and I am 24 almost 25 do think I can hit 188.2 cm before my 25 birthday..??
Editor Rob
It's very unlikely any growth at 24, though of course a tiny percentage do still gain to 25.

2cm is a pretty common shrinkage, though it's strange how you got 1cm in the past and now 2cm!
A good day to measure said on 25/Dec/19
I measure out of bed 1.71.4m and at night I am 1.69.4m.I have a shrinkage of exactly 2 cm.My height hasnt changed for more than a year did I stopped growing?Btw I am 19 and turning 20 in a few months.
Editor Rob
If it's a year and no signs, then you might have finished by now
Sharanya said on 24/Dec/19
Hi Rob. In the morning, I measure around 167cm. By mid afternoon, 2-3pm, I measure 166cm. At night, I measure as low as 165cm, sometimes 166cm. What height should I claim? All the listed heights above are barefooted.

Merry Christmas to you.
Editor Rob
165 or 166. Personally I claim my lower range, but a lot of people would go with the height they get measured at the Doctor's...so if you were near 166, just go with that.
Elman Ambri said on 24/Dec/19
Hi Rob, I really appreciate your patience and warm responses in all your forums. I love what you are doing. Keep rocking!

Merry Christmas to you and your family from Malaysia! ⛄️🔔🎄

Donnoy said on 22/Dec/19
if my wingspan is increasing in height does that mean I am going to have a growth spurt soon ?
Editor Rob
Sounds very possible you might be going through growth soon.
Nickg said on 21/Dec/19
Hey Rob!I just measured a few mm's above 180cm 30mins after weaking up.Do u think its ok to claim 180?Also if i am almost 16 yrs old do u think i could reach 6'1?
Editor Rob
Chance of hitting 6ft 1 still. Personally I wouldn't claim out of bed height, though some folk like to go with that.
James Edward Crowley said on 20/Dec/19
Rob i looked at this product Super Growth Enhancer most people would consider.does it really work to make people grow taller most people say it works some say,I wonder if you will consider for men who are under 6ft,and women under 5ft 6in the websites says this product can add 2 to 4 inches of height.

Editor Rob
Looks like herbal remedy dressed up as a growth enhancement. I'd always be cautious about any of these pills.
Cameron Wright said on 20/Dec/19
Thanks so much, Rob! I actually measured and you were spot on. I was 177.2! Could I claim 5' 9.5" - 5' 10"?

Since I'm around that range overall.

Thanks for helping me walk tall!
Cameron Wright said on 19/Dec/19
Hey Rob, I'm 174.9 at night, literally under 5' 9". How tall would I be out of bed and average?
Editor Rob
177cm may be possible straight out of bed, give or take a couple of mm
Christian 6'5 3/8" said on 17/Dec/19
What was your height loss pattern from a month ago to now? i've been lifting weights and strengthening my back muscles for years, but my height pattern hasn't really changed. (I still lose around 3/4" a day at the same rate) But I've noticed that I've gained a couple mm's from 2016 to 2017, but that could be posture or disc related.
dgm97 said on 17/Dec/19
Hello Rob.

I am 179.6cm out of bed, 178.7 after 7 hours awake and 178.1 after 14 hours awake. Is it fair for me to claim 179cm as my height?

Editor Rob
It's ok. Personally I would go with my low, but others can go with middle value or some like the morning height.

One thing is - as long as nobody is claiming height that they can't measure barefoot, then it's fair.
Canson said on 17/Dec/19
@Jdubbz: what are you measuring these days?
Jdubbz said on 17/Dec/19
Hi Rob, is it possible for better posture and a stronger back (via heavy lifts like deadlifts and rows) to decrease shrinkage? I've noticed that I used to lose height after 8pm, but for the past month of heavy lifting at the gym, my height loss pattern has changed. I'm thinking that stronger back muscles are able to stabilize my spine better, does that sound possible to you?
Editor Rob
Maybe it somehow has helped a little with your discs ability to retain water content?

Or with some people, they improve hydration and might notice some days they maintain a better measurement.
Yanat said on 8/Dec/19
im 183.5 cm at night how tall would be in the morning
Editor Rob
Would possibly hit near 186
Police said on 5/Dec/19
Rob my brother is 185 exactly cm on good lazy days, but his morning height is 185.8... neither 186... how is possible so little gap only 8 mm beetween morning and evening? However he is very sedentary only going to school with bus just sitting hours at school and not very active physicaly, he doesn't walk neither sports... it's very passive.... but when he's active he drops to 184.4-184.5... sometimes 184,2 at very worst.... should 184 been more reasonable for him than 185 in that case?+

How's that much difference beetween active and non active days?
Editor Rob
1cm would be the low end of the daily shrinkage range.

But sometimes the 30-second out of bed height really can be a few mm more than the 5-minute out of bed height, which might in some cases account for a few mm missing from the total shrinkage.
TomDeB said on 1/Dec/19
Hello Rob, and congratulations for your huge work. Here is Tommaso from Italy.
I'm 32 years and a half old, 180 lbs. Today I woke up at 7 AM, after a bad night (got nightmares); measured at 10 AM and was 188 cm, now at 9 PM measured at 186.5; considering that was all after a bad sleep, can I enlist as a "strong 6'2"?
Cheers from Milan!
Editor Rob
I would class you as a strong 6ft 2 out of bed, but I think generally would see you as 6ft 1.5-2 range.

As long as you claimed 187 or 188 it is reasonable, because you measure both those figures.
Melo7 said on 29/Nov/19
If I’m 5’11 at night, how tall would I be in the morning??
Editor Rob
5ft 11.75 to 6ft and a bit is possible
Rampage(-_-_-)Clover said on 22/Nov/19
RandomPerson, honestly if you genuinely measure that height barefoot regardless of what time it’s really fair game. 99.9% of people on the street wouldn’t debate you on it. You certainly have more entitlement to it than an insecure 6ft2 range guy who claims it and believe me they are never in short supply!
RandomPerson said on 21/Nov/19
Asked this on the forum (as RandomPerson) but probably better asking here. Something that's been confusing me. As discussed below, I claim 6'4" (on the dot) but is there a certain amount of hours I have to be in that range for me to legitimately be that height? So, like, if I've been awake for 7 hours and I start to dip a smidge under that height (so like 6'3.9), am I not 6'4"? I start out being 6'4" and 3/4 when I wake up. 5 hours later and I'm still over the 6'4" mark by a touch. Or maybe I'm measuring wrong....
Editor Rob
If you fall under a fraction, it's reasonable to round up, but if you fell to say 6ft 3.25 or something at night, I'm not sure I'd claim 6ft 4...
Joseph175 said on 17/Nov/19
Hi Rob, I wake up at 177.5 cm and goes to bed at 175.1 cm. Without injuries and surgeries will I ever drop below 170cm after aging? Or is that unlikely? Thanks
Editor Rob
You might drop to 170cm if you reach age 90! Most people in late 80's will have lost near 2 inches (men), some less, some more.
Toni said on 14/Nov/19
Hey, Rob!
Please answer a couple of questions:
1) My height out of bed 186.5 cm and before bed 184.2 cm. Am I tall?
2) In your opinion, how tall is Cristiano Ronaldo out of bed and before bad?
Thank you!
Editor Rob
I think Ronaldo could be 188 range and at worst 185

You are a tall guy, maybe just a bit shy of ROnaldo if you met him
Connor Gannon said on 13/Nov/19
Hey, Rob. I'm 6' 1/8" about 20-30 minutes after waking up. By the end of the day, I'm around 5' 11 5/8". What should I claim? I find that some girls doubt my 6' claim. Why do you think that would be?
Editor Rob
Some people will find you shorter or taller, but the fact is you are 'almost 6ft'. I would claim that
Jonah Wells said on 8/Nov/19
Seconds after waking up, I'm 5'10.75. After being awake for approximately 14 hours, I'm around 5'10 flat to 5'10.25. What height should I claim? A solid or weak 5'10?
Editor Rob
If you claimed 5ft 10, I doubt anybody is ever going to question your height...claim 5ft 11 though, and you might find some raising an eyebrow.
K-rod said on 5/Nov/19
Hi Rob,

I wake up at 181cm and am 179.9- 180cm before bed. What should I claim?
Editor Rob
you sound like an almost 5ft 11 guy. 'About 5-11' might be a phrase to use?

Ultimately people should claim a height they are comfortable saying, without lying about it.
Rem said on 4/Nov/19
Rob, after these year and half of making exercises of stretching, swimming, runnning i actually increased my height 1.2 cm (i was 173.5 at my total lowest, now 174.5). I am turning 22 in some months. Could it be that i grew this amount of height because i improved my posture? I've got scoliosis, maybe i just forced my posture abd my muscles to be stronger. I still believe that i can grow some milimetres more because my grandparentes told me they grew a little bit after 20
Editor Rob
You could have improved your spinal alignment with all that exercise.
Dave Abrams said on 4/Nov/19
Hello, Rob, if I am 6’3” and a half (or just over) after being awake for 13/14 hours, could I claim to be 6’4” or is that a stretch?
Editor Rob
For a portion of the day you are that 6ft 4 or just under, so if you want to round to 6ft 4 go for it...most people who see you will probably think you are that range
okbymeman said on 3/Nov/19
Hey Rob, one thing I've noticed is that, as far as I can tell, you've never presented video evidence of yourself measuring as low as 173. Maybe if you did that it would put to rest all these accusations of you being taller than you claim.

Anyway, my low afternoon/evening height is anywhere in the 175.4.- 175.7 range, but never 176. Just out of bed height is normally a little over 177, like 177.2-177.5. Would you just say 175 cm as your metric height if you were me?
Editor Rob
I think claiming 176 with your stats is fair enough to other people, though 5ft 9 would be what I'd claim as it is a good fit in imperial terms.
Ken Ogu said on 3/Nov/19
I’m 192cm barefoot in the morning but 190cm barefoot at my extreme low . What height should I claim?

hey rob,
i havent has the chance to measure my morning height but by evening (this one time recently got measured around 8 o clock) i am roughly 5’10.25-5’10.5 barefoot, how tall would u predict i could be at morning and noon? thanks

Possibly 5ft 11.25 within 30 seconds of wakening up.
Kabir said on 27/Oct/19
Hey Rob,
My brother is 184.2cm before bed after being 15 hrs awake and around 187cms out of bed or maybe 2-3mm below that,1)so is he a solid 6'1"?,2)what height should he claim?
Editor Rob
I would say he might fall into weaker 6ft 1 territory than a solid 6ft 1...though most people will probably view him as around 6ft 1 because for a decent chunk of the day he'll be near it.
DeMarcus23 said on 26/Oct/19
Yo Rob, I was reading the comments below me and u sure thats not true? Doesnt extra bodyweight result in more spinal compression?
Editor Rob
It could depend how much, if you are talking 30-50 pounds I doubt there's any effect, but 150 excess pounds? It would be an interesting experiment to be able to test it, but I'm not even sure anybody has done a paper on the topic.
James Arthur said on 25/Oct/19
Hey Rob, so I was actually talking about the effect of weight on daily height loss. So morning-night height loss. Isn't that height loss due to the compression of the spine, so theoretically the more weight the spine has to support, the more it will shrink? For example when I wear my backpack I lose an extra quarter inch that way.
Editor Rob
The effect of backpack versus say 40 pounds of extra weight distributed around your body would be different. The forces of that backpack weight are greater on your spine.
James Arthur said on 24/Oct/19
Hey Rob, what do you mean by being heavier reduces your ability to stand tall? Also, are you sure that if someone were to gain like 50 pounds, mainly muscle, and most of their weight was on their torso, wouldn't that apply more force on the spine, resulting in it compressing slightly more? Maybe a quarter inch or so?
Editor Rob
I think 75-100 pounds of excess weight is a point which could increase chance of your posture/stance being effected slightly, but if you still do exercise/stretching, it might not have that much effect.
James Arthur said on 22/Oct/19
Hey Rob, how much does weight play into daily height loss? If someone were skinny and let's say we're to gain 50 pounds, how much more height would they lose throughout the day? Maybe an extra half inch?
Editor Rob
I don't think 50 pounds will make any difference, but the heavier you are the more it might effect your ability to stand tall.
sherwin said on 21/Oct/19
Hey Rob, got a question
If someone is 5 8 15/16, almost 5'9 out of bed.. 5' 8.25 5 hours after wake up, and 5' 8 on the dot if not 5'7 and 7/8 what would you call their height on this site?
Also would that be a normal amount of height loss from morning to evening or a bit much?
Editor Rob
It's not much different than myself so I'd call you a decent enough 5ft 8
Salvia666 said on 18/Oct/19
Hey Rob, I've got a question
If I am 174.5 just out of bed and 172.6 after 14 hours awake , what height should I claim?
Editor Rob
Claim 5ft 8 as that is what you are.
Trevor said on 14/Oct/19
Hey rob my height puzzles me it seems to change allot or I guess inaccurate readings I stand with good posture most of the time I have been measured multiple times once for the army I was listed at 5’11 but i measured at 5’11.5 I’ve measured at 5’11 3/4 at the doctor with a stadiometer but when I measure myself at my house I’ve been as low as 5’10 and 1/8 I don’t understand this
Editor Rob
Unless the tape measure was broken or your wall/floor in terrible state, it seems a huge discrepancy.

I would find another room or house and remeasure with your own tape measure. Ultimately it's easier to be accurate when you have the time to take a proper measurement.
Arya said on 14/Oct/19
Hi Rob,

What do you think I should claim for my height? If you could please give me your opinion, I'd appreciate it. I use morning heights because I heard athletes tend to go with their heights in the morning.

In the morning after waking up at 7 am, I'm 177.6 cm
At 11 am, 176.7 cm
At Noon, 176.4 cm
Morning average is 176.9 cm
Editor Rob
If I had those stats I'd just say 176, but I can see how if you went for a 10.30 appointment, the nurse might call out 177 as you'd be closer to that...it's not that unreasonable to say that figure either.

Claim what you feel comfortable saying.
Mag123456 said on 14/Oct/19
I measure 184cm right out of bed on normal days, and usually around 182cm at bedtime... Would you classify me as a solid 182cm? And could I go with 183 cm, but normally I am only 183 cm for about 1-2 hours a day, as I hit my low at about 181,8-182,2 7-8 hours out of bed. What would you go with?
Have a nice day, Rob.
Editor Rob
Yeah I'd say calling yourself a 182cm guy would rarely have anybody questioning your height, most will see you very honest and a big proportion probably will be surprised you aren't claiming higher figures!
Walad said on 10/Oct/19
Rob does lack of sleep mean you will shrink even more than you usually will because in the last 4 days ive been sleeping for like 3 hours a day and today i woke up at 7am didnt measure but usually my morning height is 174cm and night height doesnt ever get less than 172.5. However today i woke up after 2.5 hours sleep at 7 and then went gym and worked out at 3 where i measured my height on the stadiometer as 170.7cm is that because of lack of sleep or working out or i had a theory that the stadiometer is not as accurate as measuring at home and when i measure myself at home i do it properly so it is not because i dont measure correctly thats for sure
Editor Rob
We all have a low range and extreme low, but there's a limit to how much the discs are going to lose. Maybe the stadiometer knocked a bit of height from your true measurement...
Ulf Jonas Hiller said on 5/Oct/19
Hey Rob.
I find it very strange when I people here going back and forth about what height they should claim. There should be one reference point everyone can agree on. Why? Well, how about because if for example, an insomniac has been up for 36 or 48 hours, odds are that person has shrunk at least a full inch (probably happens even sooner, maybe after just 24 hrs).
I *guuuueeess* noontime could be agreed upon, but that would require everyone to wake up at the same time so an adjustment would have to be made to be x hrs (eg 4,5 or 6) after waking up.

But my opinion is that the only objective way to measure and compare people's respective heights is as soon after waking up as possible (say measure within the hour).

Don't most people go get their passports and driver licenses early in the day?
It's just a shame there are no organizations enforcing measurement of everyone at roughly the same time (e.g. one hour dedicated to this each day...could be at noon, for instance) and that way at least everyone would be measured more or less equally.
Editor Rob
Unfortunately there is no agreed upon time - when people get their height measured, it will vary, but in their medical files that figure (at that moment) will be recorded.
jayp said on 4/Oct/19
Hello rob if very relaxed posture I measure 176 out of bed and 174 before what do you reckon I claim 5’8.5 I personally don’t care about height as I was always the shortest throughout school I remember being very similar height to my mother who is 5ft 1 when I was 14 so I got kind of lucky I should of been a lot shorter do you think?
Editor Rob
Claiming 5ft 8 would be too low I feel, 5ft 8.5 seems very fair for you. I doubt many people are every going to question it!
Kabir said on 1/Oct/19
Hey big rob,
I am about 6'1" or maybe a fraction less that(at my low) , my morning height is varies between 187-188cm,can I grow upto
6'2", if I do some exercises? I have already turned 19,and what height should I claim now?
Editor Rob
At 19 the odds are lower that you will grow. I'd say any further growth is a bonus
MoMo18something said on 27/Sep/19
Hey Big Rob,
I am 183 cm out of bed, but before bed I am only 2-3 mm’s above 181 cm and even measure 181 cm flat on the days when I workout.
So do you think claiming 182 cm is fair ? Would that make me the same height as 182 cm 50 cent or Nick Diaz for instance ? If not what would a celeb with these stats be listed as ? Thanks !
Editor Rob
182 is a median claim, so it's not unreasonable. I think 5ft 11.5 listings would fit or look similar to you in person. Some 11.25 or 11.75 might also look quite similar.
AKFIT2000 said on 25/Sep/19
Thanks for your response Rob.

Can I just ask what you think about Growth Factor Plus? I have read the description but can't see any negative reviews about it. It makes sense to me but then again I'm not a medical or height expert.

What is your opinion?

I was considering taking it to push me till 6 feet (I'm already on Glucosamine Sulphate) as I am 19 and don't have any other options. I've probably maxed out at this point.

Is there any chance that it increases my morning or evening height?
Editor Rob
Diet and right amount of vitamins certainly plays a role, but I'd study the ingredients of that product and see that there might be other vitamin products with same ingredients but much cheaper.
AKFIT2000 said on 24/Sep/19
Rob, could I claim 181 CM or 5'11.25"?
My morning height is 182.8 CM and my evening height is 180.3 CM.

My afternoon height is normally either 5'11.125" or 5'11.25" but sometimes when I workout, it causes me to maybe reach 180.2 CM or 180.1 CM by night time due to heavy lifting.

Overall, my both of my shoes add over an inch (I own a pair of Nike Shox too).

Let's say I was a celebrity and you knew of these stats. At what height would you list me? If it makes any difference I have corrected my posture and I have thick hair.
Editor Rob
It would depend on how you looked with others or in person...it is very possible anywhere from 5ft 11 to 11.5 would be a listing.
Bori said on 23/Sep/19
Hi Rob, I'm 19 and stand at 174 cm in the morning and shrink down to 172.5 cm at 10 pm. I'd like to claim 174 cm but I know it's not completely honest because of the spinal compression throughout the day. So what should be my claim?

Also, is it possible to prevent this compression by stretching everyday? Moreover, do you know any effective exercises that can serve the cause?
Editor Rob
Some people have found taking glucosamine helped very slightly their evening height.

Unfortunately the nature of gravity and movement means our discs do lose some water content. I would just claim 5ft 8 if I were you, or round to 173.
Kabir said on 12/Sep/19
Hi rob,
Can you tell me why do people shrink for sometimes after they take a bath?
Editor Rob
Maybe they are curving their spines in the bath and it puts stress on lumbar.

I should say I've tested it myself and not found it to have any negative impact, but I am taking a bath after being up 3-4 hours!
netxnet said on 8/Sep/19
Hi Rob, my morning height is 183.8 cm
and lowest evening height 182.5 cm.

Do you think saying "I'm 6 foot tall" is reasonable and fair?

Also, I've just turned 18 and I'm physically active, do you think if I could ever reach 6'2"? I may be a little too optimistic LOL.

Thank you.
Editor Rob
I'd treat any further gain as a bonus...at the moment, it's fair calling yourself six foot if anybody asks!
Gagu said on 7/Sep/19
Hy,my dad is 6.2or6.3 but I am 6.1and half an inch at 18 can i grow taller than my dad upto 21 .my height same as morning no change
Editor Rob
Still a chance, but don't be too disappointed if you don't hit 6ft 2...at 6ft 1 you are already tall range.
Ulf Jonas Hiller said on 6/Sep/19
I went over to the police station today and measured 185 exactly. I had woken up at 10 am sharp and had gone to the dentist in my own town, but then I had gone by train to a nearby city to go to a bank there. Finally, I got to the police station well after 1 pm to take my measurement. Except for tw0 things: 1) I didn't get much sleep the night before as I was up late in the morning. 2) I had been walking around literally for hours in that city (I know from experience walking shrinks me). So I'm just wondering what I should consider my "standard" height. I think when just out of bed after a good, long sleep I'm usually somewhere close to 6ft 1 & 1/2 in. Don't most people consider their morning height their "standard" height? Or should I maybe just think of myself as a 185cm or 6'1?
Editor Rob
I don't think claiming 6ft 1 is unfair, I would go with that.
DarkPower729 said on 29/Aug/19
I used to be 184.3cm in the morning and 182.3cm before bed until I was 23 (so a solid 6ft), but then after I suffered from acute depression, stopped going to the gym and worked as a labourer (bad lifting form) and my posture started to suffer immensely- back became hunched, neck curved up and shoulders were always rolled forward. I got noticeably shorter (night height became 181.1cm +/- 2mm) and my weight ballooned from 102kg to 120kg-this lasted about 2 years. I’ve since quit that job and started corrective postural work and training in the gym but I’ve only regained a little. I’m now 183.4cm and 181.7cm at morning/night (181.3cm after heavy squats) and my spine’s pretty much constantly in low level pain once the evening comes around- mornings are usually pain free. I hear glucosamine is good for spine health and recovering height. Any thoughts?
Editor Rob
Very possible you did some damage to discs that meant a bit of loss, but it's very early in life to lose height.
Oded said on 29/Aug/19
Hi rob, do you know if Height averages in countries are based on the morning or on the evening height ? Or average of both ? Thanks
Editor Rob
Some might be self-reported, but if they are taken from proper studies, then I would think it's more mid-morning to afternoon range rather than evening height.
Aaryan Malhotra said on 29/Aug/19
Hi rob,
I measured myself 184-185cms,at the midnight(past 4:30), I was awake for almost 13 hours.I am taking rest for a very short span of time since 7 or 8 days.Generally when I am on a good routine my morning height is about 6'2.5"(189cms) {just after I wake up}.So what is my original height and what height should I claim? Is it fair to claim a weak 6'2" and will I come back to my original height if I take good amount of rest?
Editor Rob
That's a big variation from your top morning to low evening! Claiming 6ft 1 or 1.5 is ok I think
Logan Sunada said on 29/Aug/19
Hi Rob

Although you are really 5'8 3/8" , you clam 5ft8

In USA where people use imperial system and people just round up, what height would you claim if you were 1/2 inch inbetween 5'8 and 5'9?
Editor Rob
I fall to a low of around 5ft 8 1/8th.
Logan Sunada said on 28/Aug/19
Hi Rob!

Morning height is 177.7 and lowest i get after 16+hours awake is 175.9

Most of the day i spend on the computer so i tend to stay around 176.5cm

Is it fair to claim 5'9.5?
Editor Rob
It's not unreasonable. I think 'just over 5ft 9' would also be covering your kind of height range.
Arthas said on 25/Aug/19
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.
Arthas said on 24/Aug/19
Is it normal that my 14 old brother doesn't lose almost any height beetween 1 hour after bed and 12 hours after bed... but maybe because he's very sedentary and only sitting whole day at computer?

I noticed he dropped half an inch only at 9-10 pm and after.... but before didn't shrink at all almost... is that normal?
Editor Rob
That is a bit bizarre, though maybe his spine wasn't under as much stress during daytime and then by night the discs 'gave up' and compressed a bit.
PBandJJJ said on 24/Aug/19
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
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?

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).

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.

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'

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
could be 5-6mm
15m178cm said on 16/Jun/19
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.
