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

If we have two people the same height, you will find some with nearer 4 and some with nearer 5. In such a situation the person with 5 inch will think the other is taller, since nearly everybody is judging height from their eyelevel.
yuley said on 23/Jun/18
rob so hair makes no difference to our measured height, would you say hair makes any difference visually ? Like if two people were the EXACT same height but one had more tuff up there would he get pegged as slightly taller by many?(have you done this before) or would it make virtually no difference because people can see he is not taller just has more hair.
Editor Rob
Well the difference is tiny...but if some people had thick and coarse hair, that has some potential to effect the measurement. The person might not push down fully and if they do, there may well be a bundling of hair around the point where the can hits the head.

Hi rob bit of a silly one, can damage to a rotator cuff effect our height?
Editor Rob
It might effect your posture slightly, but it won't have any effect once healed.
wert said on 21/Jun/18
Hey rob would you say getting massages are necessary, and could they help increase our height? Or would keeping good posture and doing yoga be more then enough.
Editor Rob
I think they are beneficial, but won't make you increase height...apart from maybe help make you more supple, which I suppose might make you hold a better height.
master said on 21/Jun/18
rob would you say if i have a wingspan two inches greater than my height I have long or relatively long arms?
Editor Rob
A little longer than the average, but if it was 3-4 inches that would be quite long.
Bwin said on 21/Jun/18
Rob would you say that most people gauge others height by comparing eye levels? Is this a good way of guessing height given the person in question doesn't have an abnormal eye level?
Editor Rob
Yes, nearly everybody would guess height from their own point of view (eyes).

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

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

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

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

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

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

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

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

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

You might get the odd short comment.
Oliver said on 23/May/18
Click Here
Rob,I'm 5ft 7¼. How tall do you think my mother is?
She said she was 4ft 11 in her prime. She's now 62 yrs old.
Thanks alot.
Editor Rob
She might be 4ft 10 today...and lost an inch.
Ja533 said on 20/May/18
Hey Rob lately I've been waking up around 2/16 of an inch lower than my normal morning height. in the last week I've been stressed out and been getting 6 to 7 hours of sleep compared to my normal 8 9 hours of sleep does the stress have anything to do with me not reaching my normal morning height
Editor Rob
That 6-7 hours might be effecting your almost 1/4 inch difference.

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

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

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

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

Some people drop fractions, others round up to say 9.5!
Pnf said on 8/May/18
My recorded height is 175.7. When I wake up usually Im 175.3, in the day Im 174.4 usually and when I go to sleep Im 173.8 on my lowest. My recorded lowest height was 172.7 when I was so sick and tired but that was once and never more. I claim 174 or 5'9 ..is that right height for me Rob or should I claim at 5'8 ?
Editor Rob
You could claim 5ft 8.5 ok.
beaner said on 7/May/18
hey rob would you say an inch is a greater than average lift in shoes/trainers?
Editor Rob
I think an average range (from looking at all this) is around 0.9 inches. 1.4 is a big foowear amount, 0.5 a smaller footwear thickness.
heeelo said on 7/May/18
hello Rob, if my height in the morning is 168 cm and at night 166.5 , what should I say my height is ?
Editor Rob
tell people 167cm.
PeterNo said on 6/May/18
Hey rob, my morning height is 168cm after working many hours and at night I shrink to 166.5 cm what should I claim?
zyvick said on 3/May/18
Is it fair to say i am 5'10.5 if i wake at 5'11 and after 5 hours of working a standing job I measure at 5'10.5. Also my absolute low is 5'10.25
Editor Rob
Yeah I think that sound perfectly fair.
justsomeguy said on 2/May/18
I'm like a bit over 5'9 and a half 3/4??? idk the measurement barefoot. Would claiming 5'10 or 5'10.5 too much of a stretch?
Editor Rob
Many folk in your situation would round to 5ft 10...you might also consider 'almost 5ft 10' as an answer.
Zlasku said on 2/May/18
Rob, I am 192cm range out of bed and 190cm before bed. Is it fair to claim 6'3" even though 190,5cm is a flat 6'3"?
Editor Rob
Yes I think that sound reasonable to tell people 6ft 3.
Harry said on 30/Apr/18
Hi Rob. Do you think you would dip a few mm under 5ft 8 if you ran a marathon? I am running one this year, and I am going to measure my height and weight. I will let you know what I measure and weigh before and after. I think it would be fair to call it an extreme low too.
Editor Rob
If I got dehydrated or put under an extreme workout like a marathon it would be interesting to test an extreme low measurement. I doubt I could do a 1/4 marathon these days though!
Ethan188-189cm said on 30/Apr/18
I am 189cm (Most likely 188) and I have recently turned 16, Rob how much taller do you think I will be? It has been stressing me and my GCSE's are in 5 weeks so I need to focus! Thanks, Ethan
Editor Rob
I wouldn't even think about height and focus on exams. I'd say the odds of reachin 192-3cm are quite reasonable, though there's still a chance you might not grow any further.
Zlasku said on 30/Apr/18
Rob, do you think that most people lie about their height?
Editor Rob
I think on average people inflate by about 2cm or so. A good proportion will be honest, but there will be those adding 1-5cm, with more extremes being over 5cm.
Gport321 said on 29/Apr/18
Hey rob, my morning height is 191,3 i
shrink to 189.8 what should i claim?
Editor Rob
I'd claim 190cm
cmillzz said on 27/Apr/18
Rob, most disc injuries won’t have a big impact on height, right? Like I would think maybe a couple mm at most.
Editor Rob
If it is a bulging disc it could be a few mm's. It might effect surrounding discs or your ability to stand as tall as you can, depending on the severity of herniation.
uy5r3 said on 26/Apr/18
Hi rob I measured myself at 5'9.5 after working a standing job for 5 hours about 6 hours after waking is this a fair claim
Editor Rob
That seems an honest claim
Heightfan said on 26/Apr/18
Hey Rob. I measure my height with tape measure, which is taped on the wall. Then stand as tall as possible and measure my height using my fingers. How accurate is this?
Editor Rob
It's roughly accurate, but an object on top of your head should give you a good idea to within a small fraction.
Heightfan said on 25/Apr/18
Hello Rob! You've pointed out earlier that some disc injuries can cause height loss. Did you mean that it stunts one's growth completely or can a person grow after the disc herniation for example. Ketä say that a 17-year-old male faces this.
Editor Rob
You could still be growing, and have an injury which doesn't effect bone growth.
cmillzz said on 21/Apr/18
Rob, a sitting job will still get you down to your low height after 8 hours, right?
Editor Rob
You might be pretty close to it, especially if doing two 4-hour sessions.
Ankit wazerkar said on 20/Apr/18
Sir I m 173.0875 CMS in morning and 171.1325 in evening. So is it normal ?
Editor Rob
It's a typical shrinkage, about 1.8-1.9cm.
boome said on 18/Apr/18
rob would measuring myself after a 5 hour work shift involving moderate lifting be a good time to measure my height?
Editor Rob
You'll be pretty near your low mark by then.
JRC 98 said on 18/Apr/18
Hey Rob...I measure 187cm in the morning and 185cm at night

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

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

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

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

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

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

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

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

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

Some smaller herniations can resolve naturally, but bigger herniation might need surgery.

Hey Rob, I was wondering if you happen to lose mm or even a full cm by just putting on your shoes? I've experimented a bit and when I put on my shoes while still lounging around the house all day, I end up losing a few more mm than I normally do if I lounge around the house all day with being barefoot. Its a bit frustrating!

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

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

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

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

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

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

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

Bill is still very close to 6'2 nowadays.

Hello Rob,

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

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

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

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

Can an inversion table help?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

@Kazko Bartlemo

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

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

So if you are comparing the heights of two people, and you can't compare them straight out of bed, you should take weight into account. Case in point, Obama and Trump. They seem very close in height, but Obama is very slim and Trump is somewhat heavyset - so I'd wager confidently that Trump gets out of bed marginally taller but the advantage is gone by the time he finishes breakfast.
Kazko Bartlemo said on 3/Jan/18
Rob my height in the morning is 187 cm and in the night is 185 cm, am I 6'1 or 6'1 and a half?
Alex 6'3 said on 30/Dec/17
Rob it's right to say, generally, that we losing around 1.2 cm from morning height to afternoon, and 0.5-0.6 mm from afternoon to evening height? That's would be a lost of 1.8 cm in total.
[Editor Rob: on average from afternoon to evening it's more like a 3mm...but it depends on the time you wake up.]
Chris said on 29/Dec/17
Hey Rob, how many hours of sleep do you think you need to get your highest morning height?
[Editor Rob: a full 8 hours, maybe 9 to reach optimal range...but it also depends if you are curled up or lying flat on your back mostly, that might determine whether you hit the highest possible mark.]
@HeightcrazyRed6ft said on 29/Dec/17
Just some family members I´ve measured:

1997 age 39 195,8cm midday, age 58 194,2m low.

1985 age 36 152cm, age 48 150,3cm, age 68 148,2cm all low
( not genetically small, at age 12 was seriously hit by a drunken cardriver and after 6 month coma never grew in height again)
Usually man height from this generation of both sides of my family is 5´8.5"-5´11".

1990 age 25 192cm, age 52 186,2cm both low - lot spine-problems, herniated discs

169cm late morning, 168cm evening, lot of measurements during her 30´s. Today age 60 she´s 167 late morning, 166cm evening


So, with all the studies, who would´ve thought that the tallest person with the least bodyworkout had the smallest heightloss?

So yeah, strange things happen... genetic is a big part

But Robs Routine is a little piece of gold,
we do it daily.

(I think its veeeery important watching such vids often... to ensure you´re doing the squats right...
my honey sleeps btw...)

You will be under your normal-low right after.

Check up your girlfriend first or you might lose more height than you wanted:)

Rob, if i am 175.4 out of bed, avg daily low 173.4 and extreme low 173.0, what is more accurate, 173.5 or 174? Also how much do you grow on average by 17 yo to peak?
[Editor Rob: if you gain 3cm after turning 17 you are doing better than average, which is less than 3cm.

You seem a solid 173cm, you could claim 174 as you might find by 18 that is your low mark.]
Commas said on 29/Dec/17
Hey rob, I’m normally 6 foot throughout the day but due to a lot of physical labor lately I’ve noticed a decrease in my height. Are there any exercise techniques to regain my posture? This wouldn’t bother me but my spine feels more tense than usual.
[Editor Rob: I would buy a chin-up bar and incorporate some basic hanging to help decompress the spine. You can also do some other little exercises with a bar, like knee raises or other stretches, which might help a little with posture.]
5'9 dude said on 28/Dec/17
Rob, after 8 hours of sleeping I am 178 cm on the nose , and I can measure a weak 175 at the end of the day depending on how active I am maybe drop to 174 , is this normal and will the shrinkage decrease as I get older I am currently 19 years old , and is there any chance I can gain 1-2 cm from healthy diet and exercise? I have already gained 1.2cm at 19 years old , thanks .
[Editor Rob: daily shrinkage decreases, but you won't really see that effect for several decades. Once into 60's and through 70's the gap between morning and evening will get less...of course you are also going to shrink a bit as well.]

You are probably identical - there's no harm in being specific, especially if you are being honest about it.]

Maybe it's possible to gain height ...
ALEXANDRE ALVES BR said on 17/Dec/17
I honestly think that a loss of height can be avoided with a replacement disk surgery
ALEXANDRE ALVES BR said on 16/Dec/17
Hey Rob it's necessary to stay awake all day to measure the lowest height???
[Editor Rob: you could hit your low point if you don't drink much, do 5-6 hours of hard work...you might bottom out at your low and not lose much more.]
lastango said on 14/Dec/17
Hey Rob, I'm 5 ft 6 at my lowest before bed, what could I reasonably claim for height ?
[Editor Rob: if you claim 5ft 6 you are very honest and people value honesty in simple things...

but say you measured only once at 11am and got 5ft 6 1/3rd....it wouldn't be wrong to claim it either!]
cmillzz said on 14/Dec/17
Rob, do you think an injury to the neck (such as whiplash or a disc injury) can cause some height loss? And if so, to what extent?
[Editor Rob: yeah I would say some disc injuries can lead to small height loss, but also if they effect other discs over time, then that might accelerate height loss.]

Rob I had a friend sleepover at my house today and we decided to measure our height to compare morning with evening.we are both 20 years old bit he is born in march and I in May. Out of bed we both measured exactly 184cm. Around 8 pm I got 182.5 cm bit my friend got 180.4 cm how can he shrink this much?
[Editor Rob: his discs seem to expel more water than yours, it is the quirk of daily height variation...some folk might only lose 1.5, others 3cm!]
Interval said on 10/Dec/17
Rob. You said a lot of these listings might be 1/4 inch taller than their low height. But my question is what if you have a low and a maximum low? What I mean is that most days you will have an average low. But on really bad days you might even be 1/4 inch lower than you are 95 percent of the time. I am usually around 5 ft 10.5. And sometimes I maintain that the whole day and other days I fall to 5 ft 10 1/4 or 1/3. But then on the very worst days I am only around 5 ft 10 at night. When that happens I feel like I shrunk. But that only happens maybe a few times a year, since I measure everyday. It doesn't happen very often but When it does happen, I get worried and feel less confident, but then I'm usually back to normal height in a day or two.

So Jenny is 5 foot 8. What is her low height? And does she have days where she's even a little shorter than she is 95 percent of the time?

So Rob, just to clarify... A lot of these height listings might be 1/4 inch taller than their 10 pm height? So for instance, Taylor Swift might fall to 5 ft 9 sometimes and Adriana Lima might fall to 5 ft 9 and 3/4 sometimes and Charlize Theron 5 ft 9 1/2 sometimes?
[Editor Rob: yes some listings might be 1/4 inch higher than a low mark.]
Alex said on 10/Dec/17
Robb, sorry for asking this because I know that you've answered it before, but I simply can't recall, what time of the day is, in your opinion, the proper time to measure one's height? Or, at least, how many hours after waking up?
[Editor Rob: I think 5-6 hours is a fair time, because it matches up with what might be the average time people in general get measured at.]
Canson said on 9/Dec/17
@Rob: it is odd my father is almost 70 and appears to have lost extremely little in terms of height. He still looks around 6’3.75-6’4 and peak was a legit 6’4. I look 1/2” taller than him back to back at 193.7-194. Maybe he was 6’4 1/8 peak but doubt more than that at a low
[Editor Rob: it's rarer to reach 70 with a small fraction lost, just due to the ageing process. But of course, good health, regular exercise, vitamin intake and even a stretching routine for suppleness could reduce overall shrinkage.]
lastango said on 9/Dec/17
Hi Big Rob, I've got two questions for you : how long do we have to lie down for a nap in the afternoon to recover almost all our morning height ? And how much millimeters is it possible to recover in the afternoon by hanging and stretching at the pull up bar ? Thank you
[Editor Rob: might need 3 hours to get back to morning height...

it's easier lying down for 20 minutes at a slight angle (10-15 degree inclination) to recover about 5mm. The hanging/stretching won't really do much. ]
Johnson said on 8/Dec/17
@Rob why do you consider Jenny 5'8?

I copied her height at home of your video discounting 0.3 cm error

7:30 (Out of bed) 174.2

8:59 173.4

10:43 172.4

14:18 172.0

18:14 172.1

She at home is 1.72 low
You Rob at home are more than 1 cm taller at your low
[Editor Rob: well she's still clearing 5ft 8 out of bed by half an inch at least, so it's not much to give her 5ft 8 even though she dips a cm under the mark...technically I would call her 172 now and 173 10 years ago]
The One123 said on 6/Dec/17
Hey Rob, generally how far from their absolute low are these celebs height listings that you post on this site. I know for all the photos you take, you are roughly near your low but could u say the same for the celebs
[Editor Rob: I'd say the difference from afternoon to evening is quite small, so maybe you could say a lot of listings may well fall a 1/4 inch or so if you were to go with absolute low 10pm height]
Rory said on 28/Nov/17
Rob, how much height would a fit and mobile 66 year old man have lost do you think ?
[Editor Rob: half an inch]
Asche said on 27/Nov/17
@Rob, I know a guy who jumps offs cliffs into water for a living and he jumps from about 100ft sometimes and he goes to many places like this all the time and frequently too, he is only 26 and preferably likes to land on his feet. I have gone with him a few times and sometimes and when you land from that high you can cough up blood and I have seen him do this sometimes, I often wonder if other symptoms could happen like on your back. When he is traveling he spends lots of time jumping off. He tells me he stops when he doesn't travel but I worry for him and for other things like height. He travels about 4-5 times a year and 1-2 month breaks even.

So my question is: If a guy who jumps off insane 100ft (sometimes just 50ft+) cliffs consistently, will he more likely to lose his height earlier and how much would it be if he was about 70 years old? and as far as I know he doesn't do height exercises too.
[Editor Rob: that activity might have compressive forces that cause some discs to bulge, so it's definitely an increased risk of injury and small height loss if he continues.]
Alex 6'3 said on 26/Nov/17
Rob did you notice that the height drop happen always at the same hours? After lunch time you have the first drop, and it is the bigger one, then around dinner time we reach the lowest levels (6-8pm). Actually, you drop height around 6pm even if you're just on the bed doing nothing. Basically we have three heights: top-middle-low, each one last around 5 hours, indeed during the first hours of the night (like midnight) you're taller then dinner time..
[Editor Rob: it follows quite a similar pattern I've found...and level of exertion and hydration can effect how fast we lose that height.]
Chris said on 25/Nov/17
Hey Rob how tall would you say a 175cm guy would be out of bed?
[Editor Rob: might be 176.5-7 range out of bed]
The One123 said on 24/Nov/17
Hey Rob, I wanna know will hunching over on a chair typing for 4 hours straight on a computer help me reach my absolute absolute low. Thanks in advance. I wanna know my minimum lowest possible height.
[Editor Rob: best doing an hour of physical labour, like say lifting weights and rotation of the spine in the activity...if you did it at 4pm and measured after an hour effort, you might be hitting your real low mark.]
Josh said on 23/Nov/17
I've got this exact problem don't know if it's too do with lifting weights. Over years I've clearly been over 5 8 near 5 9. Now I'm only just over 5ft 7 without shoes. Feel shorter and both weight machines and tape meausures clearly have me shorter than I've always been.
[Editor Rob: wouldn't rule out the chance of shrinkage from all the compressive weight lifting moves you have done.]
Pad said on 20/Nov/17
@Rob I wake up at 189.8-190cm in the morning, and before bed I am 188cm bang on, this is off doing nothing all day just being in the house can I claim 188cm?
[Editor Rob: I think claiming 188, given you wake just about 190cm is very fair and people notice honesty in simple things.

If we can be honest about such things as height, weight, it sets a pattern that we can follow through life.]
Blake said on 20/Nov/17
Rob, is your father still taller than you or has he lost more height since the height challenge?
[Editor Rob: not checked in a couple of years now, and probably won't again, I don't think older people need reminding they are shrinking.]
Woowaza said on 20/Nov/17
Rob, I’m just over 6 feet when I wake up. After working all night when I get home I shrink to just about 5’11. This seems like a significant loss of height, is this normal?
[Editor Rob: some people do shrink that much, the average is closer to 1.8-2cm range, so 2.5-2.7 is more than average, but not extraordinary.]
Intevel said on 18/Nov/17
Rob, are you still the same height?

Does a knee surgery always make you shorter? Does that mean that every NBA player got shorter when they had surgeries? Is it possible to maintain after a surgery?
[Editor Rob: some surgery might effect height, but tendon/ligament work might not do much to height.]
CD said on 16/Nov/17
Rob my dad just turned 58 and I measured him on his birthday and he still holds a good 173cm at night. This has been the same for several years now and back in 2011 he had a hospital measurement of 173cm as well. Is it possible he's lost nothing at all even though he's nearing 60? He has an office job but plays golf every weekend and rides his bike regularly (which apparently helps his sciatica, but could it also help his discs??)
[Editor Rob: yes, it looks like he's doing well height wise by barely losing anything noticeable. The age of 60 to 65 is possibly where he might lose his first fraction.]
sully said on 15/Nov/17
Hi Rob , I'm 20 years old and 5'9" tall in the evening. If I lift a 15 pound bag and put it down after about 10 seconds twice daily for 2 years could this cause me to lose height in the long run.
[Editor Rob: I doubt it.]
Myself said on 14/Nov/17
Hey Rob, yesterday i came back to home, was tired and had my back hurting the entire day on the lumbar part while i was walking and was also feeling shorter than usual...I measured myself and was apporiximately 191 cm tall (i'm not sure if i was as low as 190,7 , i also think i had some trouble standing completely straight too), compared to my morning height which is almost always 193,6/193,7....I was quite shocked, also because i felt really short for some reason...Maybe i have a herniated disc? Is it normal that i can go as low as that? Today morning i measured myself at 193,6/193,7, as always, so idk; Maybe yesterday i woke up shorter to begin with (i was lying on the bed about 8,5 hours but slept only about 6 to 6,5 hours)? That's like a 2,7 to 3 cm loss during the day. (although after like a couple of hours sitting i was back at 191,5; my usual lowest i think is about 191,5/191,7)
[Editor Rob: could have just experienced an extreme low, but also some little disc injuries might push you slightly lower.]
Mimi said on 13/Nov/17
Rob what is the average height loss for an 89 year old man?
[Editor Rob: you are talking into the 2.5-2.75 inch range as being quite common by that age.]
Johnson said on 12/Nov/17
@Rob I am 2.3 cm taller out of bed than my evening low

Is it normal my case?

I have read that you are 174.6 out of bed and 173 evening low so you shrink only 1.6 cm.
[Editor Rob: the average shrinkage is close to 2cm, like 1.8-1.9cm.

2.3 is a bit more than average, but not excessively so.

I shrink a little less than average, Jenny shrinks a bit more than average, more like your own shrinkage.]
Canson said on 11/Nov/17
@Hunch: I don’t think you measure correctly if you dip from 6’5 to 6’4 after an hour. I’m the same height as you (not quite 196 out of bed but 195.8 typically) but I only come down to 6’4.75 after an hour (194.9) and 6’4 5/8 after 2 or so hrs then can be 193.7-194 at night no less unless it’s an extreme low but even at that stage it’s usually a solid inch maybe 2.6cm as 193.2 is my absolute low after 20+ hours and being on my feet for at least 4 or 5 hours at night straight probably without sitting. The absolute low I’m not sure 100% could’ve been as low as 193 as I was almost dead on 1 mm above 6’4 but was late at night and a little bit tipsy from being out.
CD said on 10/Nov/17
Rob, my uncle is maybe 5ft10.5 (179cm) now at age 55, but he lives quite an unhealthy lifestyle since he's overweight and smokes, and also his job is quite physically demanding. Is it possible he could have lost like half an inch by now? His own claim in the past was 5ft 11.5.
[Editor Rob: yes, some guys by that age through lifestyle could have lost a half inch or so, some even more...but many can also make it to mid 50's without anything more than 1/4 lost, or even nothing!]
MrCaesar said on 5/Nov/17
Hi Rob. You often say that by 55 usually men lost a "little fraction". But what exactly do you mean with little fraction? How much mm or cm you refer?
Also, on average, when does a man lose his first cm in height? Thank
[Editor Rob: maybe 1/8th to 1/4 inch]
Danny25USA said on 30/Oct/17
Should I list my morning height or evening height as my actual? 5'7.25 and 5'6.5 are my exact morning and evening heights. I typically run long distance daily (and lift occasionally) which contributes to the height loss over a day. PS. Do you think this height is really that short or do most simply embellish their own height which makes it seem worse than it is? Just looking for your thoughts on the matter
[Editor Rob: if you say 5ft 6.5, then most people will see you as honest.

Though in experience, you might not be asked your height that often in life.]
Myself said on 25/Oct/17
Rob, what would be the optimal height you always wished you were?
I wish i was 205 cm morning and 203 end of the day...But i'm still quite surprised that my mother is 168/169 cm (her father was around 185 cm maybe), my father maybe around 6 ft and i'm 191/191,5(evening).
[Editor Rob: the only time I thought about that was usually to do with trying to get photos, being 6 foot would be the optimal height I feel to photograph with celebrities...if I was shorter than 5ft 8 I don't think I would bother.

Someone like 'Big G' who is 5ft 6 and change is too short for photos with celebrities to be as useful.]

Charles said on 24/Oct/17
Hey Rob, I have another height-related question for you if you don't mind. Sometimes, I wake up at 5'10.25. Other days, 5'11.25. I use the same stadiometer to measure my height on each occasion. When I'm at my "low" of 5'10.25, I can feel that the upper section of my thoracic spine is somewhat immobile, that is, I can't contract and extend it (I believe, it sure feels that way) as I normally am able to as long as I stick with my stretching routine.

On various occasions, I have measured comfortably over 5'11 after being up for hours, carrying stuff, exercising, et cetera. Yet, some days (especially if I have taken pain management drugs such as pregabalin and tramadol), I am positively unable to go beyond 5'10.25, even if I have slept for 8+ hours.

Do you think that this is normal daily shrinkage, or is there something more sinister to it? Does anyone else feel "upper thoracic immobility" when at their low? Has anyone here ever waked up at their low after being in bed for hours?
[Editor Rob: maybe there is some sort of seizing in the spine....there's definitely some parts of the day that you might be more flexible than others.

Seems strange though, I might even try to start a simple stretch routine if I were you, like touching ceiling, touching toes a few times a day...]
Sain't 187cm said on 24/Oct/17
Hey Rob, Im confused as to what height to claim on this website, My username says 187cm but I feel like thats high haha. I get out of bed at 6'1 7/8 or 6'2 exactly and shrink to about 6'1 1/4" right before bed give or take a couple mm. Normally when asked I just say a little over 6'1" haha.
[Editor Rob: Saint 186cm might be better.]
Myself said on 23/Oct/17
Hey Rob, if my height is around 193/193,5 cm on the morning and 191/191,5 at the lowest (maybe because i have a long torso), do you think that i should say that i'm 6'4 or 6'3? I think most people overstimate their height (and i did too until recently), and many might even say their height with shoes on (really ridicolous)....So what should i do? ;)
Is there also any way to reduce shrinkage during the day?
I am 20 years old and 3,5 months, i hope i will grow like 1 or 2 cm at least, in the next 2 years...I'd really like to be at least 193 cm at the lowest...Do you think it is possible? (I really don't have much hair compared to people even like 3+ years younger, the hair of my little moustache is becoming longer and maybe in the next...6 or 9? months it will become visible enough...I also shaved it only like 1 or 2 times in my life) And do you think that correcting my light/medium scoliosis (which is more pronounced at the lumbar part of my spine) by hanging and stretching on a bar will help me to achieve that gain?
Thanks for your time.
[Editor Rob: hard to reduce shrinkage, though doing some spine exercises might help over time attain a slightly better ability for the discs to hydrate fuller, so your morning height might edge up slightly.

I would claim 'just over 6ft 3' personally, but at age 20 I think if you gained any more height, it is more unexpected than you being already at final height. ]
Blake said on 20/Oct/17
Rob, if you worked construction as your career (and didn't have any accidents) do you think you would have held on to your heights when your 20 at say 38?
[Editor Rob: I think by 40 if you had a 20 year career in a real physical job, you might lose 3-4mm by then through natural wear and tear.]
Blake said on 8/Oct/17
Rob, I to my surprise for the last couple of weeks have measured roughly 5 ft 9.5 on average out of bed after 7 hours out of bed. Would it be fair to say I was 5 ft 8.75 now?
[Editor Rob: it's probably safe to go with that as your height now.]
Hunch said on 4/Oct/17
@Jason I really can’t explain why. Hopefully it doesn’t get worse!
Jason (192.5) said on 4/Oct/17
Hi Rob, is 2.5cm of height loss extreme for someone of my height? (194.5cm morning 192cm lowest).
[Editor Rob: yes it's quite a normal and expected shrinkage for a few inches over 6ft.]
Jason (192.5) said on 4/Oct/17
@Hunch that is pretty crazy actually. I go to bed at your height (192cm) but wake up at 194.5cm. I thought that was a lot of height loss!
Richard said on 3/Oct/17
Rob forgive me for my ignorance, but when you say " static" Does that mean contraversial?
What is your own opinion ? I personally dont believe they do or could -at least not vert noticable at all. On that note I dont believe a persond height defines them as a human being. I mean, it doesnt measure integrity ,honesty or compassion in a human being. But once again thanh you for your reply. I am just curious as to your own opinion on that.Just never heard anyone mention that.
Richard C.
[Editor Rob: I just mean it is more stable, it won't change as much as our spine, because our arms don't have discs...some bone loss could occur which means the armspan reduces, but compared to our height, it will be minimal.]
Ricardo said on 2/Oct/17
Hi Rob, I have a question for you. is measuring one's height with a book on a tiled floor of a bathroom is rather accurate?. This is because I've made measurements of my height on different surfaces and I've consistently gotten values in the range 178.2-177.7 for my lowest height, yet I don't know which one is my low, because the values obtained on the tiled floor are at the higher end (178.2) while the other values on the other surfaces were varying within the range. I know the difference between the highest and the lowest value is just 5 mm, a negligible value, still I'd like to know your opinion on this.
[Editor Rob: some floors might look level, but there could still be a slight slope, which accounts for a little fraction of a difference in measurements. Sometimes taking the average from different rooms is the best figure to go with.

Using a book is ok, I would personally find a book that had a hard cover and use the spine as the part that measures the top of our heads.]
Richard said on 2/Oct/17
Rob do your arm lenghth shrink also as a person shrinks? Interesred to know this. Ive never heard anumyone say this.??
[Editor Rob: it's pretty static]
Hunch said on 30/Sep/17
I have been tracking my height carefully for a bit now to double check. I’m 6’5” (196 cm) out of bed and my typical low at about 10:00 or 11:00 PM is 6’3.5” (192 cm). However, some days when I am really struggling with my back, I can have an extreme low of 6’2” (187-188 cm) even at 2:00 PM. Is this something that any other individual is known to have? I do have scoliosis and the height loss is noticeably from being physically unable to stand straight even when I try very hard to do so. Also, I go from 6’5” to 6’4” within the first hour of waking. 6’3.5” to 6’4” for most of the day.
9gagger said on 28/Sep/17
Hey rob is it common for people under 6 feet to lose 3cm through the day
I go from 177-174
174 under extreme cases,typically 174.5 is my lowest
[Editor Rob: it's greater than average, but some folk do shrink a full 3cm]
Richard said on 21/Sep/17
Rob,haf to see if you tesponded. As to your reply- neither have I. But this happened. I dont have a valid explanation. But from what I understand the bone decay is necessary for your body to produce the new cells. Also one last interesting note. Imaging of my back and neck were horrible Some yrs ago. I also had 3 tears between my discs in my lower back and in my neck. I hurt my back when I was 19 very badly at work. As for my neck I have know idea what or how that happened. I woke up that way with my neck huting in 2006. Doc told me sometimes that can happen. But I dont know. Maybe the rips or " tares" in my back and neck healed and thats how? Im just ad freaked at this as anyone. But I keep remembering every time science tries to say this is the definitive rule or law( in example : the worlds flat- man cant fly ,etc...- try explaining a t.v. set to a mdieval knight!) Science has been wrong. I mean in a100, a 1000 yrs from now well probably know stuff that right now in 2017 we cant even begin to concieve. Anyway, its happened and Im no closer to understanding as you are. Thanks for replying.
Ricardo said on 20/Sep/17
Hello Rob, I am thinking about buying a portable Stadiometer, which one would you recommend me? one having a very small error! Thanks!
[Editor Rob: depending on country, I would just look at medical supply companies as usually those will be best price. Seca are still one of the better ones and the portable version is only 1/8th inch off (the one I have). Their latest models I don't know, I haven't checked accuracy yet!]
Richard said on 20/Sep/17
Rob Im not kidding,joking or definitely not lying as I think your response indicates tat. I have contacted 2 medical proffesionals who know me and they believe me. They said that this might not be good though. The closest ive come to seeing anything remote was that a brain tumor can cause this. But only in people that are still growing. However I did find a research site that said theres some evidence that if a person has bone decay and something about calcification and that you body still releases hgh ( just in much smaller amounts as you age) and you do also produce stem cells that there was evidence that(( I didnt quite understand all of it) but that bone growth could occur- not at the ends- but rather from between the plates. Look Rob Im no doctor and I knew no one would believe this. But I have to take a pig enzyme to replace the enzyme in my pancreas and I have a over reactive thyroid- hypo. I definitely have bone atrophy also. I startef taking a hgh supplement by the way about 4 months before this happened because I read it could help your joints. I dont know what happened honestly and my wife thought she was shrinking! I dont have a valid explanation for this and I have a funny feeling I wont be around much longer. But I dont expect you to believe me but I cant wrap my head around this either. I do know I am not making this up and quite frankly it scares me. But before you just start assuming people are dishonest why dont you have some" miracle growth" in your soul and start by not trying to amuse youself and your readers at someones expence. I dont blame you for not believing this as it doesnt fit anything that we ,or as we know it. But as I said ,this is crazy and I dont know what to think of it. I dont have any smiley faces on this phone but If I did I would send you back a sad one. With that Rob ill sign out and not come back to this site. You can just chalk it up to " some crazy guy" and ill go back to worrying. Ive been hesitant about going to the National Institutes of Health her in Maryland. Im not a big fan of people probing and inspecting me and saying. are you sure you werent ever that tall already? Man, I dont know. Maybe one day well know or rather science will. Have a good and " normal" life. Mine certaintly became strange. But if you care to , google height increase as an adult research and you might find what I read.
[Editor Rob: it certainly would be an interesting research study for medical professionals. I do know there are some people who suffer from late closure of growth plates, and so have still gained height in late 20's, but age 50 I've never heard of before.
Fernando said on 19/Sep/17
Rob when I was 18 years old and I was 185.5 cm and now I'm 22 years old I measured 184.5 cm I can not find a logical explanation of this, I think it was because in those 4 years I had a great depression and the only thing I did at that time was playing videogames all over day and eat pass from weighing 80kg to 125kg which is what weight nowadays the combination of all those factors will have reduced my height?
[Editor Rob: sometimes you need the exact same setup (room/floor/tape/method) to see if height loss occurs, because 1cm isn't huge, even the time of day can effect it.]
Richard said on 17/Sep/17
Every time I write something it never ends up on here . Do you think im a different person? I just wrote again the other day of an incredible event- at 52 yrs old I jus grew 2.5 inches. This isnt one of those nut claims! Ther could be a significant medical reason for this. By the way, i just started looking at this site when I noticed John Waynes height on here. Youtube vids of him at home etc....he was exactly as he his wife and his secretary claimed. Its funny, people will downgrade everyone else to try and achieve his or what they think someones height is. Thats crazy. Better yet warch his olfer movies. I usef to have movie books that had many pics of the making of movies. For instance when a close up came of randolf scott standing eye to eye in the spoilers, scott wore boots and wayne was in his socks. Thers another scene out on the board walk where they stand eye to eye then wayne walks off. Then you can actually see where they stop the camera and start it again with just scott standing there so he can walk off. There is a sign behind them and you can clearly see the difference in scotts height so he can the walk off. Yeah they did all kinds of little things like that back in the fay. See Greg Palmers bio. He talks about how big he is and how hollywood wantef the heros adversary as big as the heroes for " the showdown" he was called for wayne 5 times and appeated as james arnesses adversary 21 times on gun smoke. Just thought youd be interested to know. But This crazy height increasr Ive had worries me as my health overall isnt great. You can contact me if youd like at. rindycedmond@hotmail.com
[Editor Rob: your epiphyseal plates reopened after lying dormant for 30 years and now at 51-2 they started producing more bone...certainly sounds like a height miracle 😁]
Blake said on 12/Sep/17
Rob, I don't quite understand the difference between a low and extreme low I had a more average day today and I measured over 5 ft 8 3/4 at the end of the day yet the couple of days before I had been feeling sick and barely any sleep and being still for nearly the entire day (im talking a couple of hours for 2 days, food etc and measured 174.2 so what is my low? Is it in between the measurements or is it the height I measured when I was up for basically 2 days?
[Editor Rob: I think if you take a measurement at 7-8pm (after being standing or active for several hours in afternoon) and do it several times over a week, just take the average as your typical low.]
Blake said on 11/Sep/17
Rob, is humans height growth done completely while asleep? I have a theory that more youngsters might grow during summer as firstly they do more exercise on average and in my case from spring to summer I got more than double the sleep I got during the winter
[Editor Rob: yes, when asleep the body repairs and grows during it, which is why exercise (to promote growth hormone production), variety of food (to give our body the right nutrients) and the actual sleep are all important as teens.

Staying up till midnight playing Doom or mario or whatever could have a little impact on our potential growth.]

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

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

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

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

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

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

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

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

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

Click Here

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

The sedentary lifestyle that many sadly adopt over 50 I believe contributes largely to some losses.]
Mahad95 said on 22/Jul/17
Hello rob my name is Mahad......I measured my self 4 times in gym once twice I was measured 176cm and twice I was measured 175cm but it wasn't any measuring error for sure. But yeah the thing is when I was measured 175 twice I didn't eat or drink anything that morning........if you don't take any glucose in the morning and check height do you shrink??
[Editor Rob: it's possible you were dehydrated a little and so your discs weren't as thick as if properly hydrated.]

Colin said on 16/Jul/17
Hey Eob, I have a strange question about my friend. He was 17 years old when I saw him last time and he was about 6'2 in that time because we were in basketball team and I was in the same room in high school when they measured our heights. He is now 24 years old and I haven't seen him in last 7 years almost and he is about 6'4.50-60(1.94cm). Is this really possible according to science-way? From 6'2 to 6'4 after 17? I am 6'2 and he was really taller than me like 2 inches min.
[Editor Rob: yes, it is quite possible, he just had more than average growth after 17...]
Ricardo said on 15/Jul/17
Hey Rob, I have a question to you regarding losing height during summer. Given on a summer day, a person is prone to sweat more often, Is it likely to lose height (from out of bed height to normal low) more quickly throughout the day on a summer day?
[Editor Rob: it's always possible, but we are talking very small fraction.]
Nate said on 11/Jul/17
Rob, perhaps you can help me with this question, I am a 25 year old male.

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

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

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

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

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

I'd be delighted to hit 65 with only 1/3rd or 1/2 inch lost!]

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

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

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

I live much, too much to home and I pass several weeks 3-4, without go out from house for studying.Also if I have only 25 years old, I have fear that I have a lack of vitamin D, because I don't sunbathe. Since several years (5-6) I sunbathe not much,except in summer where I sunbathe enough on the beach. Could I shrink my height, in this time? I drink a cup of milk everymorning. I am worried. Dear Rob, Is it possible shrink at 25-30 years old, for a lack of vitamin D for few sun?
[Editor Rob: Even on overcast days there is still sun rays, of course it's less intense.
I doubt you have shrunk...some foods have vitamin d, some cereals also have it included.]
TK said on 1/Apr/17
Dear Rob, I'd be very grateful for some advice: am only 18; recently broke my foot, now out of cast. The leg which was in the cast is slightly longer than the other leg, and I am 1 cm shorter. Is this most likely a result of bad posture??
[Editor Rob: TK, your legs may simply be 1cm difference. If it is only a few mm that is nothing to be concerned about, but if 1cm, maybe a small dr scholl orthopaedic insert you wear in one shoe to balance your discrepancy is worth looking at.]
Judd said on 31/Mar/17
[Editor Rob: yes very reasonable, if I was 75 and only lost 2cm I wouldn't be unhappy!]

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

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

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

Or height loss is mostly starts at 50 for man?

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

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

Rob, do you have potential on a rough day to be under 173cm what sorts of activities could do this?

I have a friend who says her grandmother loss 12" in height. She was 6' and less 5' when she died. Is this remotely possible? I mean no one mentioned anything about her having legs amputated, which might explain it.

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

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

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

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

Inteval said on 11/Feb/17
Hey rob my experiment with the inversion is still producing similar results. Before the inversion I would be 5 ft 11 in the mornings and 5 ft 10.25 before bed. Now I'm 5 ft 10.75 in the mornings, but 5 ft 10.5 before bed.

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

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

So in summary correcting posture, stretching and staying well hydrated does actually work! (obviously). Again when my posture was horrible I likely stood shorter than 173 and looked like a 5'7" range guy at night but correcting it has made all the difference. You've just got to stick with it. I know it's only a cm (173 evening to 174 evening) but incorporating all of the above has helped my overall body/health, the benefits weren't just height based. I also feel a lot more confident and secure with who I am as well as opposed to when I started and I was very insecure/unhappy. Just go for it.

Hey Rob, my height is same as yours 5'9 in the morning and 5'8 before bed. Is it possible to increase with exercises or natural ways after age of 21? Like 1 inch or 2-3 cm, what do you think?
[Editor Rob: Rick, I think if you have the time, it is something you could test for 6 months.]

hey Rob do you think glucosamine can help retain morning height..I'm 179.8 in the morning and 177.5 at night do you think it can stop me from dropping below 178
James said on 26/Jan/17
Hey Rob. If I'm 178 cm out of bed, 176.5 cm in the afternoon and around 176 at night, maybe a little bit over, is 5'9.5" a legitimate claim?
[Editor Rob: James it's not unreasonable to go with that figure.]

Hey rob. With the inversion I'm having conflicting results. Normally I'm 5 foot 11 in the mornings but 5 ft 10.25-4 at night. After using the inversion for a few days I'm 5 ft 10.75 in the mornings but am 5 ft 10.5 at night each night. So even though I'm a quarter inch shorter in the morning, I'm only losing 1/4 inch in the day. And I'm sitting and driving a lot, so I don't know why this is. Could the inversion table make you able to maintain height better during the day?

Anyways, inversion takes up about 6 feet. Think about it if you have any space in your living room or garage. It's relaxing.

Hey Rob, I just got an inversion table. What I don't understand is I was a quarter inch shorter the next day when I woke up, after using it 10 minutes the night before. Can an inversion table make you temporarily shorter when you first adjust to it?

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

I'd need to test inversion table myself, but I have no room for such a thing, so can't say why you experienced a little loss!]

Kevin, I lose the same amount of height - morning 187, before bed down to an alarming 184.5 cm.

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

Also why does Rob give for example 184cm celebs anything from 6'0.25" to 6'0.75"? Why isn't the cm/in conversion done automatically?
[Editor Rob: all heights are stored in feet inches. The nearest whole cm value is displayed beside it.]

Hello, Rob thank you very much for this information first of all. Do you think will it ever be possible to increase height naturally after age of 21? I mean, except bone lenghten surgery. Do you think will there be other methods to increase height after age of 21 in future? Maybe in 20 years or so... What do you think about this topic?

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

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

The only problem is if everybody could become tall, then there is no basis for that...everybody essentially becomes more average.]

Hi Rob. I've noticed what appears a small increase in height. I've been taking glucosamine and chondroitin for about 6 weeks and my morning height has increased to 177.1cm from about 176.6cm. Will have to monitor the measurements to see if it's down to error but I think it's an actual increase.
[Editor Rob: in some people it can give a few mm's boost to the discs, in some it won't...certainly means you might be a more comfortable 175cm at night.]
Yes yes said on 13/Jan/17
Rob, how will you react the day you wake up and measure yourself and see that you're not 5'8" anymore? ;P
[Editor Rob: I will snap the tape measure in half!

no, I would be happy to live long enough to even be as short as 5ft 6, I will take being 85 and 5ft 6 over dead in a coffin!]
