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.
Aleksandr said on 12/Feb/20
Hello Rob. I’m 186,6-187cm right out of bed and 184,4-184,8 before. What is my legal height in cm and feet?
Editor Rob
I think if you claim 185cm or nearly 6ft 1 it is fair.
Kabir said on 12/Feb/20
Hi Rob,
My cousin measured himself 184.5cms or 184.6cms before bed and he was 187cms right out of bed.Is it fair to claim 6'1" for him and if not then what height should he claim?
Editor Rob
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

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! ⛄️🔔🎄
Editor Rob
I wish all visitors from all countries a Merry Christmas!
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?
Editor Rob
190 or 191, but if in feet/inches I'd say 6ft 3
mark thompson said on 1/Nov/19
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
Editor Rob
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.
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?
Editor Rob
If I were in your situation, I might be going with 179cm
Hussein said on 11/Jul/19
Hi rob, does swimming like 4 hours can shrink to my low? If it is 167.8 can i go with 168 as my height? Also 10 hours after bed
Editor Rob
It's going to get you to your low if you do a fair amount of swimming, because even though there's less resistance, you are still using a fair amount of twisting motions in your spine.
PaulSP said on 10/Jul/19
Hi Rob, I’m 186cm at my tallest and usually around 184,5cm at my lowest, so I claim 6’ 3/4”. Would it be reasonable for me to claim my metric height as 185cm, as opposed to 184?
Editor Rob
Yeah, it's reasonable to go with 185cm
Dmeyer said on 7/Jul/19
Actualy today i was 183,2cm 20mn out of bed so probably easy 183,6cm right out , so still close to Peak morning height , facing wall IS much easyer to stand fully tall
Editor Rob
Yes, you are less likely to have the can slip or bend your back (and thus not stand as tall).
Lildumars said on 6/Jul/19
Hey Rob at the morning I measure an exact 177 cm but today after walking home from spine loading exercises such as deadlift and squats for 2+ hours at the gym I measured at 174.5. Is such drastic height loss possible...is this okay? I’m a little concerned because it seems like a lot of height lost.
Editor Rob
You could have hit your low height...it's not an extraordinary amount to lose...
criss said on 5/Jul/19
Rob, I'm 183 in the morning and 181 at my lowest. Sometimes I'm 181.5 at lowest or even 182 if I'm rested.
Claiming 182 it's not bad, isn't it?
Editor Rob
It's fair to go with middle value - one thing is certain, at least it's not a false height. Many folk with your stats will give 184-5, many 183 too, but a smaller percentage (compared to those claiming 182,183 and above) would only go with 181 low height.
Dmeyer said on 5/Jul/19
Rob my max morning height is 181.3 and my lowest is 177.8 is that a lot of height to lose..also two years ago my max was 181 and low 177.5 do you think I grew in that period
Editor Rob
It is a lot, but sometimes when we are younger our discs are at their best health and can absorb more water. Wow that IS huge 3,3cm loss at under 6'0
Dmeyer said on 5/Jul/19
Hi rob , its likely to loose 2mm of morning height by late 30s early 40s for example back to wall After a good sleep i use to be back to wall 183.6 ish lately i think i am nearer 183,4-183,5cm , yet at night i am still similar range 181,2-181,5cm depennding , facing wall i am 1-2mm taller as i alter my spine less , today i was 182,8-182,9cm 30 min Out of bed of course i could have droped 6-7cm within 30mn i will check next Time a mn out of bed ,many people will measure 10mn out of bed so they droped alreasy 2-3mm and then measure 3pm on a normal day then the différence will be just 1,5cm but if they measure out of bed and then 7pm on theyr feet all day the différence will be nearer 2,2cm and near 3cm if they are 6'2 or more
Editor Rob
Yes you could lose a tiny amount like that. There is a definite difference of a few mm even with 10-15 minutes out of bed compared to 30 seconds out of bed.
Kiers1996 said on 2/Jul/19
Hey Rob first thing out of bed I'm exactly half a mm under 175cm. I think you and me could be height twins because right before bed I got a low of 172.9cm. I never feel tall but then I dont feel short unless theres a 6ft7 guy in the room then I feel towered lol.
Editor Rob
Yeah those stats are very close to mine. IN the UK, 173cm feels lower average range - when they say UK average is somewhere around 5ft 9 zone, I believe it.
Martin Novak said on 1/Jul/19
Hi Rob, I´m 199cm and I would like to be smaller. Is possible to decrease my height at least 3cm? Is there something what can I do? I´m 33 year old.
Editor Rob
Unfortunately not practically...slouching can cause more issues long-term...wear as thin sneakers as possible, grow a long beard to elongate the head, keep hair short, walk on lower side of pavement/sidewalk.
Elliot Christian said on 30/Jun/19
Hi @Rob, I wake up at 187cm first thing in the morning, 185.5 by the afternoon and 184 (sometimes 184.5) by the evening.
Would it be fair to just tell people I’m 6’1”? (185.5cm)
Also, i’m 22 now, when would I begin to see a decrease in my height?
Editor Rob
Many people would claim 6ft 1 with your stats...some might go with 'almost 6ft 1'
Pitaz said on 25/Jun/19
Rob my max morning height is 181.3 and my lowest is 177.8 is that a lot of height to lose..also two years ago my max was 181 and low 177.5 do you think I grew in that period

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

I'd say you could go with about/almost 5ft 10.
Lazar99 said on 23/Jun/19
@Rob,If someone has lost some height due to damaged discs , How could he cure that ? and Is is true that you can't regain the lost height ?
Editor Rob
I think some people through surgery have regained height in back...but also, if their posture has worsened over years, exercise and stretching routines might help them regain their youthful posture.
Buckshot said on 20/Jun/19
If I’m 1.84m at a low would I be lying if I claimed 6’ 1” ?
Editor Rob
Almost/About 6ft 1 might be fair to say.
Jason97 said on 19/Jun/19
Hi Rob. Im 169.5cm in the morning, and drop to 168.7cm in the afternoon (2-3pm) and at night i drop to around 168.4cm (8pm). Is it okay to claim 169cm?
Editor Rob
It's probably fair to go with that mark if you are claiming a metric height.
Hamadd823 said on 16/Jun/19
Rob, what is the average loss in mm between a 2 hour out of bed measurement and a 6 hour?
Editor Rob
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.
shantanu lal said on 6/Jun/19
Hey rob i just wanted to tal to you about my height:
Its goes maximum to 185.6 in the morning to low as 183.3-183.6 in night. How much do you think i might be exactly because i cant figure it out !
Editor Rob
Some people with those stats might just call themselves 184cm.
Piers said on 2/Jun/19
Rob, I'm 21 years old and am currently scared that I lost some height.

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

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

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

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

If you fall under 6ft it won't be by much
so said on 9/May/19
if i'm bang on 5'11 after being awake 17 hours and 5'11 7/8ths in the morning on 6 hours sleep and 6ft on 8+ hours, what height should i claim?
Editor Rob
For a portion of the day you are a fraction over 5ft 11 - whether you want to claim a bit over 5ft 11 is up to you.
Michael2002 said on 9/May/19
Hey, Rob.

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

What was your lowest registered evening height?

!Hello Rob!
How much will be a 1.88 in the morning, afternoon and evening? I usually measure 189.2 in the morning and 187 in the evening ... Do I have 188?

Hi Rob, is it possible that someone in the same heightrange as you could shrink more or less than you? As an example,I read a Comment under the page of Mbappe where you responded that he could pull of 181 cm out of bed. But somehow he is only listed as 178,4 cm. I'm usually 5'10 1/2 out of bed and 5'9 7/8 after 12 hours of beeing Awake. Am I just lucky or is that normal? And by the way, what would you list me as, if I would be a Celebrity? Love your Website!😊
Editor Rob
Yes, you may find some people shrink say 1/4 to 1/3rd more than another person at the same morning height.
Heightguy said on 24/Apr/19
Hey Rob. 3 questions
How many mm would glucosamine tablets add?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

First of all, kudos on such an awesome site !

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

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

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

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

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

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

At the moment you are a decent 6ft 1/2 inch guy.
Ethan, 190cm said on 17/Dec/18
Heyo Rob, don't know if you remember me I was the guy who was curious about my height just before my GCSEs and I was stressing. But good news! I passed with flying colours!
I am now turning 17 in the latter part of April and I am a weak 190cm and my question is... Will i reach 6,4?
Editor Rob
At 17 some folk finish, others still gain a bit, some even a few inches more...at near 190 I wouldn't give it much thought, already it's a very tall height. 193 is possible. Report back in a year to see what happens!
Charles Giege said on 16/Dec/18
Wassup Rob, do you think weight gain leads to height loss? Because I am pretty sure I've shrunk ~3-4mm after gaining 10-15 kg
Editor Rob
I think in a scenario such as 100 pounds, it might effect the spine a little or cause somebody not to stand quite as tall as they used to. Small amounts though like 20-30 pounds I doubt it has any sort of effect.
akee said on 1/Aug/18
Rob if im 175.26 with an inseam of 30.5 inches is this still within average? noticeably quite short?
Editor Rob
Yes it's within average. Under 29-30 is shorter.

The type of trousers/jeans play a role in how you might look.
cmillzz said on 29/Jul/18
Another question for you Rob: why are disc injuries so common? I just think it’s weird that our bodies were designed that way. It shouldn’t be so easy to have disc injuries, yet it happens all the time with many people. Do you have an explanation as to why it’s so easy to injure our discs? I just don’t get why our discs have to be so fragile.
Editor Rob
Over exertion or excessive loads can cause these disc injuries.
cmillzz said on 27/Jul/18
Rob, I lose a huge chunk of my morning height in the first couple hours, is that normal? I’m closer to my evening height after just two hours out of bed, whether I’ve been standing or sitting the entire time.
Editor Rob
Yes, the first 2-3 hours of being awake will cause us to lose a good chunk of morning height.
yuity said on 26/Jul/18
rob is 1.5 inch shoe really noticeable?
Editor Rob
Yes, a 1.5 inch heel is quite big, well for a man's heel. It is more obvious, but if you are looking down at somebody's shoes from within a few feet you probably wouldn't notice it being thick.

hi rob I measure 5'9.25 after working 12 hours on my feet all day no less, and on my days off I measure 5'9.5 at the end of the day. would you say I am a good 5'9.5? considering I wake at just under 5'10 maybe even the full if well rested.
Editor Rob
Calling yourself 5ft 9.5 I think is fair enough.

hi rob would a 30.5 inch inseam be average for 174cm ?
Editor Rob
It is within average range yes, though if it was 29.5 it would be into a more shorter range.

rob does smoking effect our height in any way?
Editor Rob
Long-term it isn't good for your body, including height - with age, smokers are likelier to suffer more issues that could knock a bit more height from their frames.

Rob, do you have any advice for getting tallest possible measurement 5-6 hours after waking up?

Thank you.
Editor Rob

I think avoiding tasks that put stresses on spine. Even something like doing washing up puts more strain on our spines than you'd imagine. Keep hydrated during the day.

Rob, is 2 cm a typical shrinkage for someone who wakes up at 192 cm? Or perhaps a full inch?
Editor Rob
2-3cm range would be typical.

Rob, do you think a disc herniation in the lumbar section of the spine would be more likely to cause height loss than a herniation in the cervical section?
Editor Rob
Both can have effects, but lumbar are a bit thicker so potentially damage to those discs could give slightly more loss.

rob would taking an average of my morning height and night height be correct? I want to claim a height that i average over the day and measure at even several hours after being up sometimes, around 5 to even 7 hours. Also why do you claim you're absolute low of 5'8 and 1/8 rob? you clear this height a majority of the day?
Editor Rob
It's not unreasonable to go with that, I know a fair few people who might do it.

@Rob: in regards to Jason Wick, what do you consider inflating or deflating your claim? And where do you fit the “out of bed” height and “extreme low” (height that you only hit once in a while) into the equation as far as a claim?
Editor Rob
Whilst out of bed is a height you measure,I think claiming it goes against what most people claim - which is the height they measure after being awake several hours.
Adding an inch or pretending shoes are part of human height is to me an inflation, and rounding down an inch or even if 5ft 8.75 and saying 5ft 8 is a bit deflating.

Hello Rob,
very strange situation. I can walk, play football whole day (13 hours) and shrink only 1,5cm. But in other day i can do completly nothing and shrink 2 cm. Common is 1,5cm range but something is like i told. Its because bad hydration or what?
And one more think, if i have curvy spine can i get from him 1-2cm more after fix posture?
Editor Rob
Might be hydration, but also sometimes the way you sit in a chair can place excessive pressure on discs that can contribute to greater loss. Driving I've found gets me down to my low quicker than sitting on a computer chair.
Sitan said on 13/Jul/18
Rob, I am in a military and we wake up at 6 AM every day. Today I measured myself 15 hours after waking up and I was 189,2 cm. Was this my lowest measurement?
Editor Rob
Without becoming really dehydrated, about 189 might be your real low mark.

Rob, does tight/restricting footwear make you lose more height during the day? I have some tight shoes that squeeze up my feet sometimes and I feel like I lose more mm wearing them than when I wear more free/fitting footwear.

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

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

Incidentally I get 6-2 alot from other guys who claim 6'. Strange how the lying affects everything
Editor Rob
You are a solid enough 6ft that you will annoy other 6ft men who are claiming 6ft 1-2!

hi rob would thick socks increase height by much?
Editor Rob
If they were tightly woven they might add 2mm, but most I've seen barely add even 1mm.
Laduski said on 5/Jul/18
Rob, is it true that people with big foreheads usually have lower eye level?
Editor Rob
It is quite common.
gege said on 4/Jul/18
hi rob. Do you know how the national averages are done? and if so what time of day they measured
Editor Rob
In the UK, the national health survey would have taken place on average around lunch - the people doing testing would go to different homes during the day to do survey, including height measurement, so overall we are looking about mid-day as the average.

Rob have u experienced noticable height loss in celebrities ( like more than 1 inch) while meeting them in different periods( like in gap of several years)
. Can u pls post comparison pictures if u have any?
Editor Rob
There are a few I'd say looked say half inch shorter after I seen them over the last decade, people like Kane Hodder seem shorter than they did 10+ years ago.

rob what is my actual height I wake at 69.875 inches and go to bed at 69.25. I have measured once or twice in the evening (5-7 hours of being up) and got 69.5 inches.
Editor Rob
Some folk go with the average or a lunch time height, others go with morning or evening.

As long as you are not inflating or deflating your claim, I think in the middle of your range is perfectly reasonable to tell people.

Heights are barefeet estimates, derived from quotations, official websites, agency resumes, in person encounters with actors at conventions and pictures/films.

Other vital statistics like weight or shoe size measurements have been sourced from newspapers, books, resumes or social media.
