How tall was Robert Wadlow

Robert Wadlow's Height

8ft 11.09 (272 cm)

American, who became famous as The tallest man to have ever lived. Wadlow was a celebrity in his short lifetime and worked as a spokesman for a shoe company. At age 13 Robert measured in at 7 foot 4 inches, weighing 250 pounds. By the time of his 18th birthday, he clocked in at just under 8 feet and 4. In February 1939 his official measurements at Washington University were 8 feet 8 1/4 inches barefoot, weight 491 pounds. Robert's physician measured him in February 1940 at 8 feet 9 and 1/4 inches (also reported as 8ft 9 1/2), then his last measurement was on June 27th 1940, where he was recorded as standing 8 feet 10 and 3/10th's, which was reported in numerous newspapers at the time of his death.

However, a figure of 8ft 11.1 inch surfaced from Guinness Records, who have reported that height since the 1980's, contrary to what was being published at the time of his death. This figure seemingly originated in a 1943 letter from the Physician to Wadlow's father, which stated rather than the reported 8ft 10 and 3/10ths figure from June 27th, that his last measurement was in fact 2720mm (8ft 11.09).

This is the highest photo of Robert! According to the TTM calculation expert's image correction, he corrected the original tilt image by turning left 1.5 degrees before calculation! The reference object for correction is the window behind Harold! Father and son are in the same horizontal line! Robert's shoes are 9 feet 0.25 inches, and his socks are 8'11! Harold is standing in front of Robert! Robert Shoes 8 feet 11.25 inches, socks 8'10!

Even if not technically quite at his tallest, that photo is one of the most majestic, if not THE most majestic images taken of RW. Click Here

Here's a clip of RW celebrating his 21st birthday with his family, uploaded by smileshy22. The family is similarly grouped and they do a great pan up to RW's full height. You can see that RW's youngest brother Harold Jr. is that bit younger than he is in the still photo above. Click Here

In this photo, Robert's sock reaches an amazing 8'10, no doubt

Hi Rob

In case he would not have died at age 22, do you think that it would have been possible for him to reach 3 m of height ? It seems that he would have never stopped growing.
Editor Rob
I don't know, but over 9ft was looking very possible for him...
Tall In The Saddle said on 26/May/21

Interestingly, if we ONLY take Feb 1939 and Jun 1940 as RW's last two "official" measurements, we can calculate his growth over the 16 month period and pro rata it to extrapolate him being about 8'10 4/10" by Feb 1940 (coincidentally or not, that's close to the fig of 8' 10 3/10" reported in newspapers upon his passing in July 1940). Of course, this is all just guesstimate work.

I say this because you have previously and justifiably raised question re the Feb 1940 measurement which was possibly informally made by his father and therefore, "unofficial". Also, without due equipment and methodology, particularly in view of someone of such extreme stature, his father's measurement might've easily been inaccurate.

On the flip side, if we accept the Feb 1940 measurement as say 8'9 1/4" that would mean RW only grew 1" over the preceding year but then went on to grow a considerable 1.85" in little over 4 months. Quite the spike but certainly not impossible.

Of course RW's growth wasn't uniform but in his final years, it did appear that his growth was slowing and I guess it allows for the possibility that images of RW in late 1939 early 1940 actually depict him above 8'10" and that much closer to his final height than we originally thought. That then allows for a growth of about .7" from Feb 1940 to June 1940 which might seem more reasonable.

It would be great if the relevant details of RW's medical files could be released without intrusion on his privacy otherwise.
asdl30555 said on 25/May/21

I don't feel very true about the 8'9 reported in the newspaper, because there were relevant reports from 1939 to 1940
asdl30555 said on 24/May/21

You are still disturbed by the newspaper report 8'9! In fact, this photo can be said to be Robert's maximum height! TTM calculation experts also calculated that the sock in this photo reached 270 height, and I also calculated the same height! I also compared several other photos taken by father and son in 1939, and the difference was also very obvious
Tall In The Saddle said on 24/May/21
I was just thinking (yes, a dangerous venture, I know) but the old saying “act your age not your shoe size would’ve been non applicable pretty early in Robert’s life. I’m a mere size 10 and can still, justifiably, be accused of acting my shoe size and not my age but no one can ever say I don’t have sole. :)
smileshy22 said on 23/May/21
@asdl30555- He's probably 8 ft 10 or 11 in the pic because of his shoes, which would make him 8 ft 8 without shoes. But with the height difference being a bit more, the pic could actually be from late '39 or even early '40! So maybe he could be 8 ft 10 without socks! :o
Matthew Lean said on 23/May/21
@ Rob Paul what would have been his morning height?
Editor Rob
something that would have been interesting to is likely based on his spine that he easily cleared 9ft mark first thing.
asdl30555 said on 22/May/21

If you compare all the photos of Robert and his father in 1939, the Robert in the family photo is far more than 8'8 height, the difference is very obvious!
asdl30555 said on 21/May/21

Do you still think Robert is standing at 8 feet 8 inches, this family photo
asdl30555 said on 19/May/21

The comparison between the 8-foot-8-inch Robert and his father is like this: the difference in height and body is not as obvious as that in the family photo

asdl30555 said on 18/May/21

Harold reflects Robert's Shoes 8'10.75! Father and son stand on the same level, Robert's shoes are 8'11.5, socks are 8'10.25
asdl30555 said on 18/May/21

Put the ruler on Harold's heel and measure Robert! Robert is 8'8! But it's not right, because the feet are in different positions
smileshy22 said on 16/May/21
@asdl30555- He isn't 8 ft 11 in that pic. It was taken in '39, but he hadn't finished growing yet unlike most 21 year olds. He was about 8 ft 8 there, so putting him at that height makes Harold 5 ft 10 and a half. It's not his usual height, but Harold could've shrunk a bit with age. :)
asdl30555 said on 15/May/21

Have you found that 5'11 Harold shoes stand in front of 9 'shoes Robert, Harold's visual effect is 5'8, the visual effect is very shocking
asdl30555 said on 12/May/21

If this picture was really taken in 1939, then he will complete all the growth in the later period of his 21 years old! Then there was no growth any more! Harold stands in front of Robert! Robert is 8'11! They're on the same level! Robert is nine feet!

In order to pursue the perfection of photos, let's finally discuss this topic! Photo left rotation 2 and left rotation 2.5 compare each other, which is more suitable for photo correction! I'm a little bit trapped and want to hear from you

@asdl30555- I'm glad I could help! :)
asdl30555 said on 29/Apr/21

But I prefer to accept image rotation 2! Although it's a rough figure, the photos are closer after the experiment! Thank you very much for your cooperation!
asdl30555 said on 28/Apr/21

I did experiment 1.5, which is basically consistent with the line diagram
asdl30555 said on 24/Apr/21

I later looked at the picture and turned left 1.5, which basically coincided with the line picture

well if his Father's head isn't much more than 9 inches, then 12 inch range is possible...some of the wax models seem to put his head near that

13 inch range is possible ? Seems clearly bigger than sultan kosen head

Editor Rob
In a few photos with his Dad I think 12-12.5 might be a range, however as much as 13...I'd really need to spend time.

If the Wadlow statue had his head tilted down slightly, it could look 13 inches for sure.
asdl30555 said on 19/Apr/21

If the picture is rotated 4 to the left, it will be severely tilted to the left! The following line drawing is a correction chart! The left rotation range is between 1.5 and 2, but I'm not sure which number it is

The numbers are insane and more so when you actually see photos upholding them.

Here's 12 yo RW in 1931 standing back to back with boxer and then, future HW Champ Primo Carnera who stood an exact 6'5 3/4" and fought as high as 275 lbs (125 kg). Primo was a former circus strongman in Italy whose sheer size saw him get into boxing with some mob control in the background. Later in life, Primo also wrestled.

I was just thinking. Imagine being aboard that boat along with Robert Wadlow and Jack Dempsey to view Niagara Falls. In terms of icons, that's quite the trifecta and a heavyweight combination that I didn't necessarily imagine coming together.
Tall In The Saddle said on 27/Mar/21

Thanks you. I really appreciate the time and effort you put in to provide that estimate. Sounds very much the height we would expect RW to be hitting around the time.
smileshy22 said on 25/Mar/21
@Tall In The Saddle- I sized Dempsey in the picture with a full body pic to get a height of 6 ft 1/2, which made Robert over 8 feet! :o I'd say he was about 8 ft 8 or 9.
Tall In The Saddle said on 22/Mar/21

THANKS. How cool is that? Dempsey was mainly listed as 6'1" but I think he was more like 6' 1/2". Based on the latter height, what height would you calculate RW to be standing in the photo (even though RW is clearly not fully straight)? The hood might make it bit difficult to mark the top of Dempsey's head but given a height of 6' 1/2", we could alternatively estimate and mark Jack's eye level to be about 5'8" I guess.
smileshy22 said on 21/Mar/21
@Tall In The Saddle- 'Gentleman Giant' is only in the US (I've only seen it on Alton's Museum of History and Art, but expensive first editions are sold everywhere on eBay). The guy in the pic is definitely Jack Dempsey! (the original eBay listing verified it was him) :D

@Tall In The Saddle- This pic was taken either on his b-day or the day before (he celebrated at a hotel in Florida):Click Here

Thanks for that. Yes, I've seen that photo many times before but without any caption/context. So that is RW on his or very near his 22nd birthday. Excellent reference point. A lot of relevant detail is lost to time when photos, after multiple copies are uploaded, aren't properly described and time stamped as per the original photo. Lucky you're here to put it straight. :)

Here's an interesting photo from you very own, awesome site. RW at Niagra Falls 1939. Click Here. LOL, years after the fact I still get nervous for RW in such situations, being so tall with a much higher center of gravity than the average Joe. The ships rails certainly weren't built for a man of RW's size!

Great photo but what also caught my eye was the guy on RW's right, wearing the rain jacket with hood and holding onto RW's cane. For mine, he bears a striking resemblance to former HW Champ Jack Dempsey (reign 1919 to 1926) who would've been about 44 yo or so as at the time of the photo. Could be just Jack's "Doppleganger" but if you're not familiar with Dempsey, here's a portrait photo of Jack for comparison:-

Click Here

Finally, I noted a link on your site for ordering a revised edition of THE GENTLEMAN GIANT 1943 by Frederic Fadner with assist from Harold Wadlow Snr (which I assume prompted Harold Snr's request for a letter confirming RW's final height from his physician for inclusion in the book). Do you know if the book is available internationally or just within the US? Thanks.

Thanks heaps for your reply and analysis. All that you stated is exactly what I thought as per my prev post. The only thing I wasn’t sure about was if it was RW’s 22nd birthday. I haven’t seen any photo of RW celebrating his 22nd birthday or at least being described as celebrating his 22nd birthday.
Otherwise It seemed reasonable to guess that RW was celebrating a birthday in the photo i linked since the whole family is present except for Eugene and if it was a birthday it would’ve had to have been his 22nd. I’ve never seen a caption or date for the linked photo.
But you’ve seen a photo of RW celebrating his 22nd birthday and the suit is different so a question mark remains as to the event they gathered for in the linked photo. RW is so very tall in the linked photo, looking very close to peak.
smileshy22 said on 13/Mar/21
Tall In The Saddle- This definitely isn't his 21st birthday since the family looks a bit older. It looks more like late '39 or early '40 (Harold looks a bit thinner than pics from mid '40). Robert was wearing a different suit in the pic from his 22nd, but it could be from around that time. I'm always glad to help! :D

Re this photo Click Here

Could you reaffirm the date of the above photo? I’ve seen footage of RW’s 21st birthday Feb39. The clothing in the above photo doesn’t match the clothing in the footage. Also, RW’s youngest brother Harold Jr is older in the photo than the 21st birthday footage. So, any chance the photo is actually from RW’s 22nd birthday on Feb40 or, at least, taken somewhat later than Feb39, more likely taken in 1940?

Thanks for your reply in advance.
asdl30555 said on 9/Mar/21

In the photo, Harold is closer to the camera, standing in front of Robert's figure! If Harold is on the same level as Robert, Robert will be higher! Robert socks is 8'11! From this 1939 photo, Robert completed all the growth!
Nippu said on 8/Mar/21
Robert`s fert are not straight in that picture. Hard to tell is upper body because his jacket. I think it is pretty fair to say Robert was 9footer. In Europe we use metric system so 9ft is no big for me. 2m, 2,5m and 3m are numbers what i see. But 3m is too much for human body atleast standing.
2,5m is THE mark what u should hit. Atleast Robert, Vaino and Sultan has hit that mark. Tere might (and probably was) be others too but no 100% proof about that.

smileshy22 said on 1/Mar/21
@asdl30555- Using your ruler with Robert's left (his right) heel right against it (since yours was an inch below that), he was 8 ft 10. Putting your ruler right at Harold's heels makes him 6 ft 2, so I made the ruler bigger until Harold's head hit 5 ft 11. When I did that, Robert was only 8 ft 6! :o
Chaos Control 6'2.5 said on 28/Feb/21
I actually know how to calculate height from solitary photos. If you know the height of the photographer, angle of the camera and distance from the subject you can draw a right angled triangle and calculate their height with the Pythagorean theorem. Figured it may help with calculating RW’s real height

@Jason Jeffries

Good question re RW’s potential height loss in the future.I haven’t read anyone ever ask that. People often muse how tall RW might’ve been if not for his tragic health issue. The way I see it, all RW’s health issues were inextricably entwined with his ever increasing height. Inseparable, like the Yin and the Yang. Basically, there was always going to be a ceiling to RW’s ultimate height due to worsening physical ailments which were a direct consequence of his height.

RW’s growth chart also indicates that his rate of growth had declined in the last 2 to 3 years of his all too brief life. At the stage of human evolution that RW was born into, the same stage we are at now, I think RW’s height represents the maximum or near maximum achievable.
asdl30555 said on 26/Feb/21

It would be perfect if you could find the biggest positive photo of Robert and Harold standing together
Tall In The Saddle said on 25/Feb/21
In today’s market, RW would’ve been a huge hit on the talk show circuit and special events IMO. Aside from his height, RW made for a good interview in his own right. There would also be the potential shoes, clothing endorsements with the likes of Nike etc happy to sign him up. Hell, even Elon Musk could get in on the act, customising a special one off, oversized Tesla, perfect for the Extremely Tall Man.

U can only measured height ”around”. Robert was so tall that even smallest error his position to stand drop easily 3-5cm off. Usually Robert is not standing at his best. I think he could stand 1940 easily 9ft with shoes if he wanted. I guess he never thought that in 2021 people try to measured him by pictures =)
smileshy22 said on 19/Feb/21
@asdl30555- He most likely didn't include the hair. :)

An interesting topic! Did the doctor include hair when measuring Robert's height
Tall In The Saddle said on 18/Feb/21

Nice investigation work. Could you link the source that states that Robert’s father measured him in Feb90? Thanks.

Also, perhaps I’ve got it wrong but are we assuming that Harold stood 5’11” in shoes? If 5’11” was assumed to be Harold’s barefoot height then Harold’ could be calculated to be close to 6 feet in shoes. In turn, that would suggest that Robert was standing closer to 8’11” in shoes himself. Based on smilesshy22 calculation we could then perhaps give Robert back an extra 3/4” putting his barefoot height at 8’9 1/4”.

@Tall In The Saddle

Robert and Harold in Florida in February 1940! They are not in their own city! They've been traveling in other cities since 1940! In February 1940, the shoe industry said that Robert's father helped him measure 8 feet 9 inches! Later, in June 1940, Harold said that Robert did not have a formal measurement for more than a year! All kinds of signs indicate that Robert was not officially measured in February 1940!

John F Carroll’s growth chart

Age 12: 5’6” very normal height/above average but not tall for a boy that age.
Age 16: 6’2” tall height for his age. He grew 7 inches more in less than half a year. Like Wadlow at a young age he was able to lift heavy things almost effortlessly.
Age 17: at his high school graduation he stood 6’9”
Age 20: he was 7’ tall

Then his height slowed down he did reach 7’6” and may have stood 8 foot at one time but was very weak at that point. Then the possibility he was still growing

Yeah, I know all about how much of a physical freak Liston was
Tall In The Saddle said on 10/Feb/21

Boxer Sonny Liston was about 6' 1/2" with a listed reach of 84" (7'), an almost 12" pull. That basket ball player still beats him though with a wingspan that is 14" in excess of his own height. Liston also had over sized hands. When he closed them to make a fist, they measured a whopping 15" in circumference. Put that pre-measured around your own fist and you'll appreciate the size difference. Most of the bigger HWs, at least in Ali's era, maxed out at 13" fists. Today's HW crop may be that bigger again.

I'm a bit surprised Robert's wingspan isn't a bit more, but he was a narrow looking guy.

BeeJay Anya has the record wingspan for a basketball player, 6-7 with a 7-9 wingspan which is just absurd

Thanks for your reply. Interesting coincidence that the last photo of the seated RW and Harold dated 3 Jul 1940, states his height to be 8'9 1/2", being the very measurement in question, apparently made in Feb 1940. My gut tells me there's a medical report to back it up. Now the fun will be finding that report. :)

Thanks for the link to RW and family on his birthday! My bad. I knew it was out there but I was too lazy to look it
up. :)


I understand your reluctance to fully accept the 8'9" reported in newspapers without hard medical evidence. Just my opinion but I would guess that they did source the 8'9" figure from an actual measurement. It also fits in with his growth trend as at that time and the fact that Robert was measured on or around each birthday for many preceding years.

Robert's final measurement on 27 June 1940 coincided with and was likely directly related to the fitting of a new brace. For a long time, it seemed that the 8'11.1" figure was plucked out of thin air also until the physician's 1943 letter to Harold came to light. There's the homework, to find the irrefutable medical source for the 8'9 1/4 or 8'9 1/2" figure. :)


Can we tap your expertise again as to a confirmed medical source for RW's claimed 8'9 1/4" or 8'9 1/2" for Feb 1940 when RW turned 22 yo?

@Jason you’re overestimating average height loss. I’m almost 6’3 (5.5” above average so nearly 6) and never lose and inch, last time I did I was obese and has been playing rugby, and it was at 9pm. Robert Wadlow was categorised as obese, and I believe that height loss would increase exponentially past 7’, considering the pure mass of men that big
Jason Jeffers said on 29/Jan/21
@ChaosControl 6’2 1/2” I thought this site was late morning/midday heights? By afternoon it is highly likely especially in a physical job that a person is going to be at their low or very close to it. I would have thought it would make sense if someone’s true height is based on the average of their highest and lowest. Incidentally an average height would also coincide with his 8’11.1” but my personal belief is he lost nearer 2.25” throughout the day. This theory is the average man looses about 0.75” then it appears to be about an extra 0.25” for every 6 inch height gain. Robert was around 3 ft over average meaning about 1.5” extra height loss over 0.75”. What’s your thoughts?
Tall In The Saddle said on 28/Jan/21

Re RW and that still photo, I think there is film of that particular birthday. They pan along the family at average height then begin tilting the camera up toward Robert. Stunning. Fair play to guess he was possibly at max. height at that stage, RW is standing impossibly tall but he still had another 3" growth in him...


Yes, Arshivar's skull does appear quite long even for his height. Looks like he has somewhat comparable hands also but not quite as big as RW's. Would be interesting to get some other stats on him. In the meantime, here's some more photos:-

ChaosControl 6'2 1/2 said on 28/Jan/21
Here’s my thoughts on Robert’s height loss at his tallest
Waking up: 9’0.5.
8am: 9’0.25. Loses the first 0.25 inch from moving under his weight
9.30am: 9’0. Loses another quarter mid morning
11am: 8’11.75. Has dipped under 9’
Midday: 8’11.5. Lost another quarter
2pm: 8’11.09 as listed. This site is based on afternoon measurements
3pm: 8’11 flat. Doesn’t take long to lose 9% of an inch
5pm: 8’10.5. Someone his height and weight probably loses 2 inches by the start of the evening
6.30pm: 8’10.25
8pm: weak 8’10
9pm: 8’9 5/8-7/8
Into bed: 8’9.5. I think he loses 3ish inches through the day
Altered my old chart. This should be reasonable, him being a supergiant and weighing 500lbs (I don’t care where the weight was stored that’s pretty damn heavy)

Back to the tallest women according to Guinness in 1971 English edition. It doesn’t give an official tallest woman but mentions Dolores Pullard of Louisiana, USA as a possible candidate ( 7’3.5”- 7’5” tall). She passed around that time. This is well before Sandy Allen was in the book. It mentions 7 foot tall Gwen Bachman of Colorado. It mentions Tylia of Saidpur, India with an unconfirmed height of 7’5”. It has an article about a mysterious giantess with the skeleton in Birmingham, England it was obviously Jane Bunford. It says that minus the kypho-scoliosis she would have stood at 7’9” .

Patrick Cotter was listed at 7’10.86” before being re-measured at around 8’1” a year later.

I meant giants in general, before photography and film. Say, Patrick Cotter O'Brien, who was claimed to be a very possible 8' even. Not necessarily disputing Cotter O'Brien's claim, but if Wadlow lived in the same period, we're talking a whole 1 foot taller without any photos or film of him to go by. Perhaps that much harder to believe.

I don't know too much about Edouard Beaupre but I see there are actual photos of the guy online. He passed in 1904 so I guess there is no film of him unfortunately. Def. looks big but personally couldn't say for sure he stood 8'2". Probably worth a better look into this guy.

Imagine if we had NO vision (photos or film) of RW BUT with all other "evidence" still at hand (viz: medical verification, newspaper reports, anecdotal claims, etc). Sort of the equivalent of an alleged giant from the 1800s whose actual image has never been seen or at least only via subjective drawings.

I wonder how many people would believe RW's height IF they hadn't seen it for themselves? I'm not so sure I would've. For me, Robert's extraordinary height was literally a case of "You've really got to see it to believe it". Fortunately, we have more than enough visual evidence to satisfy ourselves.

9’1 early morning, 8’10.5 into bed. Weighing 500 pounds and being so tall will accelerate daily shrinkage
Tall In The Saddle said on 18/Dec/20
There is an old 1950s B Grade Sci Fi Horror, now cult classic, called the INCREDIBLE SHRINKING MAN.

An engulfing radioactive dust caused the title character to begin losing height and overall size at an initially slow but steady rate. At some point, much to the character's relief, the shrinkage appeared to have ceased, as confirmed by consecutive visits to the local physician. He befriended a midget girl who worked at the local carnival. He was in fact slightly taller than her, bolstering his confidence. However, after just a few weeks, to his horror, he noticed on a subsequent get together that he was now dropping height to her also.

It makes me wonder how much Wadlow might've hoped that every next visit to his physician might've somehow confirmed that his growth had finally stopped ONLY for Robert to be advised that he had grown yet more since his last visit, probably apparent by his own reckoning anyway. His height fascinating to us but likely an ongoing nightmare for Robert.

I've read that surgery was offered in the hope to stop Robert's growth but given the heavy and immediate risks involved, the family declined the offer.

Sure, completely understand your point. Photos of Carroll are curiously limited. One would think there would be a photo of Carroll at his highest claimed standing height but it's yet to be found if it exists. Here's some more detail on Carroll with two photos which show him as tall as I've ever seen him captured on film.Click Here

Re Koehler. I agree he would've believably been 8'2" at peak just not quite that perhaps on the available film with Frost. Here's a sequence that includes some older photos when he wasn't compromised but perhaps still not yet at peak. He bears some resemblance to Wadlow and his photos have sometimes in fact been misidentified as being that of Wadlow. Click Here

Re Myllyrinne. Yeah, slim shoes and it appears not a lot of heel to speak of. Vaino definitely didn't lift and I wouldn't have begrudged him a bit more heel than that. LOL.
Nippu said on 23/Nov/20
Tall in the saddle. My point is that i can give Carroll also 8ft. But i have not seen him picture there he is even clos to that. And his crutches were 6ft tall. And if he was really 8ft we calculated that itis almost impossible to had that spinal damage. Even his other parts of body did not impress me. I have been looking that Koehler video. He seems to stand that 7`10 easily. They sid he was measured 248cm. I can belive that. And i put Vaino hint above Kosen because Vaino was 252,8cm tall when he passed away.He was bending a bit. Like insaid docror in my neighbour. So Vaino was 8`3 but probably 1-2 cm when he ws still alive. Person.lost a bitbof height when he died. Stifness or so. But your right they were about same height Vaino just had better posture. Click Here Here u can see Vainos shoes and skies. Pretty slim those shoes.
Tall In The Saddle said on 21/Nov/20

Excellent vision provided. I think Don Koehler was officially measured by GWR at a max. height of 8'2". Even with Frost, you can see obvious spinal curvature (kyphosis). By the time of his passing at 55, his height was estimated to have dropped down to 7'10". With 5'11"- 6' Frost in about 1973, it's arguable that Koehler, in his late 40s, had already lost some height and as at that time, he was possibly barely scraping 8' if not actually a bit below that mark.

Tall In The Saddle said on 17/Nov/20

I've seen that photo many times before but, unless I've since forgotten, I don't recall it being properly detailed with a date, location etc.,. Lack of important detail or incorrect tagging is often the case with a number of photos of RW floating around the Net. I'm guessing there are even more recent photos out there (viz subsequent shoe promotions?) but harder to find and for all intent and purposes, RW is basically at max. height in said photo. Great stuff!

I'll just add, RW is looking impossibly tall in that photo, it's surreal and he isn't even standing fully straight. I didn't necessarily recognize the guy in the hat on RW's right to be his father and he isn't mentioned on the photo plaque. At any rate, RW was basically 1 1/2 times taller than Harold.

RW's enormous shoe can be clearly seen in comparison to the shoe of the man on his left. As preserved and viewed on its own, the heel on RW's shoe might appear average in proportion to the whole shoe but possibly that much thicker than average. However, looking at his shoes again on their own, the length to heel ratio appears perhaps higher than average dress shoes. Meaning, while his shoes were incredibly long and wide, the heel may not have been significantly increased in proportion.

At least photos of 6'11" 12 yo RW standing back to back with 6'5 3/4" Primo Carnera (easily found on Net) actually depict Carnera with the slightly thicker heel IMO. RW's heels appear very flat. Amazing to think that RW was still a full 2 feet from reaching his max. height.
smileshy22 said on 16/Nov/20

Tall In The Saddle said on 16/Nov/20

Good point.

Mine was just a casual observation that, on appearances alone, one wouldn't perceive RW as obese. Or, at least, I wouldn't. I understand the good number of variables involved otherwise. Conversely, I might say, without even knowing the specific numbers for Trump's height and weight, just based on his appearance, the obesity alarm bell rings immediately. LOL.

As to skeletal frame. For sure, based on volume alone, RW's bones are going to be that much heavier than the average bear's. Not completely sure if his bones would've been necessarily more dense though. Possibly an argument that he would've lost density in the face of the sheer volume. Likewise, while RW might've been stronger than most, constituting greater muscle mass, he would've likely been below par in terms of P4P strength. Certainly a big issue was RW bones not being able to cope with the sheer weight of his body otherwise.

Some suggest that "overweight" or "obese" people do in fact have bigger bones as a consequence of carrying a heavier load. Possibly this also contributed to the size of RW's bones, at least in the lower body which includes the femur or thigh bone, the biggest bone relative to all other bones. RW appeared to have a notably higher lower body to upper body ratio with broad hips on top.

The rationale for skeletal weight appears somewhat circular and prone to inaccuracies. They suggest that the skeletal weight of a "non" obese person comprises about 14% of total body weight. So, in the case of RW at 500 lbs or about 227 kgs, skeletal weight might be calculated to be 70 lbs or 32 kgs BUT the BMI calculator deems RW "obese" at 500 lbs.

So, I tinkered with the BMI, keeping the same height but adjusting the weight and found RW just falling into the healthy range at about 397 lbs or about 180 kgs. That would equate to a 14% skeletal weight of about 55.5 lbs or just over 25 kg. A brief check online suggest the "average" human skeletal weight is about 23 lbs or 10.5 kg. Hypothetically, if they had been able to quantify RW's skeletal weight to be about 70 lbs in it's own right, then I guess a weight of 500 lbs might seem reasonable allowing for a 14/86 split. Approaching it another way, maintaining the weight of 500 lbs but adjusting the height, according to the BMI calculator, RW would've had to have stood 310 cm or about 10'2" for a deemed healthy height/weight ratio.

Just throwing up some numbers for the hell of it. Nothing hard or fast. Certainly, as individuals incrementally deviate from average, the conclusions of the BMI calculator become that much more skewed.
J2Frenzy said on 15/Nov/20
Even if the extra weight was in his bones it still would’ve dragged him down a bit
Christian 6'5 3/8" said on 14/Nov/20
But Wadlow had an extreme cae of gigantism,which would make his bone structure a lot larger and more dense. So one can't really determine his weight by looking at his body alone.
Tall In The Saddle said on 14/Nov/20
Correction to my previous post. I said I reject 1 and 2. I meant I reject 2 and 3 (viz Rogan and Carroll) and replace them with Myllyrinne and Kosen for equal 2nd spot. Not rejecting Wadlow, of course. LOL.

@Vincent Caleb

Interesting. I wouldn't have guessed RW to be classified as obese based on appearance. I plugged Shaq's stats in, based on 216 cm height and 147 kg weight. It read BMI = 31.5, that little bit more "obsese" than RW.
Tall In The Saddle said on 13/Nov/20

John F Carroll. Yeah, it's claimed Carroll actually stood just over 8' at best with a corrected height of 8'7.75". Toward the latter stage of his life, it was also claimed that Carroll's standing height had been reduced to 7'10.5". The photo on Height Detective estimates Carroll's standing height as 7'2.5". Given Carroll's clearly twisted body and additionally relaxed posture, I think the Height Detective, with "correction", concludes a projection of 8' as being reasonably possible. But that's just 8' including correction. Not a standing 8' with a resulting correction of 8'7.75".

IMO, even if Carroll had stood 8' with an accurate correction to 8'.75" IF his spine etc. was perfectly straight, it simply isn't the same as RW managing to actually standing as tall as he did, without his spine being too compromised. IMO, some slight curvature was evident for RW in the latter stages but that's part of the wonder of the man, that he could still be as tall and straight as he was.

Anyway, popular reports have RW, John Rogan and Carroll, all from the US, rounding out the top 3, with heavily projected (not actually standing) heights for numbers 1 and 2.

Personally, I reject 1 and 2, and would place both Vaino Myllyrinne and Sultan Kosen at an equal, rock solid number 2, with actual standing heights of 8'3" a piece.
Tall In The Saddle said on 13/Nov/20

Thanks for the link. Unless I picked up on the free trial offer, which I didn't, I couldn't read the newspaper text.

I could read the date of the article however, 22 Feb 1939, which was RW's 21st birthday. Of course I take your word for it that RW was cited as 8'9.5" in the article. I've recently found other articles myself between Feb 1939 and Feb 1940 mentioning 8'9.5" also.

Clearly, something is up. RW was widely reported as being measured 8'8" upon his 21st birthday and it was even later noted in other articles that RW growth rate appeared to be slowing, having grown just 1 and 1/4" from his 21st birthday to his 22nd birthday .

I see a few possibilities. Contemporary articles are preferred but can still be wrong (see above Physicians letter in which he cites an exaggerated height claim of 8'9" for RW earlier in his life, a height which RW later surpassed anyway). I'm more inclined to believe RW was measured at 8'8" at age 21 (as more broadly reported) so therefore view the citing of 8'9.5" as either incorrect or exaggerated. The incorrect or exaggerated figure might've coincidentally approximated to RW's "future" measurement of 8'9 1/4" upon his 22nd birthday. 8'9 1/4" isn't quite the same figure but yes, an exact 8'9.5" was also reported for RW upon his 22nd birthday.

In all possibility, perhaps it's true that RW wasn't measured on his 22nd birthday and somehow, the prev. exaggerated figure of 8'9.5" at age 21 was picked up and slotted in for age 22. But then, there is the figure of 8'9 1/4" for age 22 yo and I don't believe that figure was attributed or mentioned at any prior age.

Then we have the article you prev. linked, dated June 1940, which clearly states RW hadn't been measured in over 1 year. Interesting. I'll also add that I came across one article stating RW to be of a certain height but the family acknowledged it was not yet medically verified since they used a yard at home to measure RW themselves.

Anyway, good stuff. I appreciate your methodology in confirming the facts re RW. That's exactly how I've approached same, previously lending itself to sorting out the source and veracity of the 8'11.09" listing, leading to RW's rightful reinstatement at 8'11.09".

Yea, I agree Sun Mingming might lose the full 2. Even for his height of 8’11” Robert Wadlow is pretty heavy. Definitely over what would be considered “average” for someone that height(even though he is the only one ever to achieve that height). Although BMI calculators don’t factor muscle mass or body fat, I plugged his numbers in one and it had him as obese.

@Christian: same here. 3/4” on a normal day.

@Tall in the Saddle: lol Well said! He did look compromised which is the perfect word!!!
J2Frenzy said on 13/Nov/20
@Vincent do you have any idea how heavy Robert’s weight is for his height? Even being almost 9 feet tall, 490+ pounds is massive. Any height loss under 3 inches is impossible to believe, given Wadlow was over a foot taller and 1.5x heavier than Sun Mingming, who at 7’9 and 340 himself definitely loses 2 inches
Christian 6'5 3/8" said on 13/Nov/20
Yeah, I'm 6'5" range but only lose 3/4". Even a 9 footer like Wadlow probably would lose no more than 2.5".
Nippu said on 12/Nov/20
John F Carroll by photoevidence was even near that 8`7ft. He could stand 7`2. We have make some studis. But could have close to 7`7-8ft in corrected height. There is nowone in history (as we know) who was even close to Wadlow. Even Myllyrinne was 19cm shorter than him.
Vincent Caleb said on 12/Nov/20
People who are a flat 7-0 at a low do not lose 2 inches, unless they have a ridiculous weight. Like 1.25 on average or 1.5 if they have a longer spine. Yao Ming probably doesn’t even lose 2 full inches. Wadlow easily loses over 2 inches though. I think people are starting to over estimate height loss. I know a lot of people who are 6’5” or over that still lose only 3/4. A lot depends on weight also. For example Tyson fury probably wakes around 6’8”, but loses around an inch at most. Quinton Aaron also wakes around 6’8”, but can lose as much as 1.5 inches to to his weight. There was a guy I knew in college that was 7’1” out of bed and 7’0” at night. Tallest guy I ever met, but surprisingly only lost an inch. That is a bit rare, but I seriously doubt the average 7 footer loses 2 full inches.

Man, just one day in RW's shoes would be all I could handle, if that. :)

This is the last footage of RW that I know of, at a shoe promotion, Apr 1940, about 3 months prior to RW's passing. Click Here

You can see how compromised he is, not standing his full height at any given moment, great difficulty walking and almost tripping. Suggestive of some degree of spinal curvature and other skeletal issues. Notably, his physician didn't state that any allowances were made for curvature (viz "height correction"). So, it's understood that RW literally stood as measured. Perhaps he could muster himself to be straight for the sake of a measurement or, perhaps, he missed out on some extra height due to some curvature.

In contrast, John F Carroll, The Buffalo Giant, was afforded considerable height correction due to spinal curvature for a projected height of 8'7.75" but he never actually stood that height. At best, I believe it was claimed that he stood a literal 8'. This linked page goes in depth as to whether the projected claims for Carroll were legitimate. Click Here
Tall In The Saddle said on 11/Nov/20

I know where you're coming from. The newspaper articles you provided which I have already commented on.

Particularly the 22 June 1940 article which stated RW hadn't been measured in over 1 year.

Not to flatly reject or dismiss that claim out of hand but, for mine, the jury is still out on that one. I've read RW was measured in Feb 1940, height reported as either 8'9 1/4" or 8'9 1/2" and that claim is also included in Rob's summary at the top of this page. One has to wonder where the two figures above came from anyway. Fair to say that given RW's unprecedented stature and regular monitoring, it would've been peculiar for him not to be measured in over 1 year. However, I will also say most, if not all, height charts for RW don't include the 8'9" + measurements claimed for Feb 1940.

Certainly worth looking into further.
Canson said on 11/Nov/20
@Tall in the Saddle and J2 Frenzy: I wonder what it would be like to be that height for a day. meaning 8’10 or 8’11 lol. I’d almost be scared to be that tall as I’d literally have a really bad curve in my back ducking all the time lol.

Christian 6'5 3/8" said on 11/Nov/20
I've never heard of a 7 footer losing a full 2", but I guess in very rare cases it's possible. But I bet that the most Wadlow had lost in a day was in the 2.5"-3" range.
J2Frenzy said on 11/Nov/20
@Tall In The Saddle it’s an estimate, you don’t need to get your knickers in a twist
Tall In The Saddle said on 10/Nov/20

Just an FYI. RW wasn't measured by Guinness. Guinness was first published in 1955. The initial publications in fact had RW's final height listed in error as 8'9.5" (this in fact was RW's measurement for his 22nd birthday in Feb1940). It was later modified to 8'10.3" (his final height broadly reported in newspapers upon his death). It was modified again to 8'11.1" sometime during the 1960s and has remained the same ever since. Obviously, Guinness progressed through various sources in the time line before settling on RW's height detailed in his physician's letter.

The apparent random appearance and source for 8'11.1" was somewhat of a mystery until the physician's letter was brought to light. That letter also appears to have been expressly requested by RW's father for inclusion in a 1943 Biography published after RW's death.

IMO, RW could've easily lost 2+ inches in a day. Unless he stayed overnight in hospital, it would've been impossible to accurately measure RW straight out of bed. A subset question is how long would it have taken for RW to lose the first .9"? Could the estimated time frame for same still have allowed for a measurement of 8'11.1" sometime before midday?
Vincent Caleb said on 10/Nov/20
If this is his low, he would wake up at 9-1.5. Loses 2.5 inches.

I doubt as much as 3.5", but I can see 2"+ like Rob said.
J2Frenzy said on 9/Nov/20
Here’s my thoughts on Robert’s height loss at his tallest
Waking up: 9’0.5.
8am: 9’0.25. Loses the first 0.25 inch from moving under his weight
9.30am: 9’0. Loses another quarter mid morning
11am: 8’11.75. Has dipped under 9’
Midday: 8’11.5. Lost another quarter
2pm: 8’11.09 as listed. This site is based on afternoon measurements
3pm: 8’11 flat. Doesn’t take long to lose 9% of an inch
5pm: 8’10.5. Someone his height and weight probably loses 2 inches by the start of the evening
6.30pm: 8’10
8pm: 8’9.75
9pm: 8’9.5
Into bed: 8’9 flat. I think he loses 3.5 inches through the day
J2Frenzy said on 7/Nov/20
@Rob maybe it’s average, like most Guinness heights are? I’m confident he’d wake up over 9 foot

Editor Rob
pretty much an exception yeah
Tall In The Saddle said on 1/Nov/20

Very interesting link. Thanks.

Contemporary articles are generally the best source but there seems to be conflicting information. Two articles dated 21 Feb and 22 Feb 1940, on the eve of RW's birthday and on his birthday respectively, state RW hadn't been measured recently. One could guess RW was measured shortly thereafter but then there is the 22 June 1940 article stating he hadn't been "officially" measured in over a year.

Other sources state that RW was measured on or around his 22nd birthday, clocking in at 8'9 1/4" with some newspapers also reporting 8'9.5". The 27 June 1940 measurement was simply aligned with the fitting of the new brace and most newspapers reported that measurement (final) as 8'10.3". Some newspapers actually reported RW's final height as 8'9 1/4", using his Feb 1940 measurement in error instead of the 27 June 1940 measurement.

Suffice to say, the accuracy of RW's height as reported in newspapers was a bit dodgy at different times. IMO, the 8'10.3" figure was simply an errant conversion from metric to imperial. It would be gold if RW's original medical files could be accessed and made public just for the measurements. His first measurement report is available online, very detailed measurements across the board and reported in metric.

It was good that the articles reaffirmed RW being measured barefoot whilst estimating his shoe height.

Good info and I agree that it indicates all measurements were barefoot.

You might like this. RW at 12 yo photographed back to back with HW Primo Carnera listed as 6'5 3/4". RW was about 6'11" at that time.

Primo had just arrived in the States, justifiably touted as the new HW Juggernaut. Formerly a circus strong man. So the story goes, Primo agreed to the photo shoot without properly realizing RW's immense size. They say Primo wasn't too happy to find himself being snapped with a mere Kid of 12 yo who appreciably outsized him. After all, Primo was supposed to be the new giant in town but obviously he had nothing on RW. LOL.

You would guess given the obvious logistics involved due to his size and impacted mobility, as much as he could've tried for his best early morning measurement, it would've taken RW that much longer than the average bear to get himself to hospital for his medical. Also, reasonable to assume that RW would also lose more height and more quickly in a day than the average Joe. With all that, for him to still rate 8'11.1" by the time he did present, I agree it's more than fair to project a 9'+ measurement straight out of bed. They should've organised a home visit for exactly that purpose.:) Were they aware of height loss throughout a day back then?
Editor Rob
I'm certain they were aware of variation from morning to evening, but the practicalities of testing height accurately out of bed would have needed maybe a hospital stay.
Maybe at one point some Doctor's thought they could have measured him first thing in the morning, but sadly he never lived long enough for his peak height to be discovered.
asdl30555 said on 29/Aug/20
@Tall In The Saddle
I re-read the medical report. Robert was thirteen years old and measured 218cm in February, and Robert was thirteen years old and measured 221.5cm in July. Both were barefoot, which indirectly indicates that hospital measurements were all barefoot
Andy5'93/4 said on 28/Aug/20
Hey rob seeing as some 7’0+ giants have lost a full 2 inches robert has 12+ inches on them is there a chance robert dropped as much as. 4 inches throughout the day maybe even near half a FT
Editor Rob
It's something that is unknown, but 4 inches seems a stretch. Over 2? I could believe that.
asdl30555 said on 28/Aug/20
@Tall In The Saddle
Robert's 13-year-old Medicine reports that barefoot is 219cm and then 221.5 is for shoes. Here, his measurement is not always barefoot
Tall In The Saddle said on 25/Aug/20

TOTALLY agree. Why inflate? The 2720 mm measurement is perfectly objective, exact and medically authenticated.

Not sure how anyone wouldn't find this listing as THE most desirable expression of height, accurate to a mm, with medical verification in tow. It doesn't get any better than that.

Expressing Robert's height in mm is simply because that's exactly how they measured him for absolute accuracy. Certainly not to make him seem even taller. All other unit expressions of Robert's height are merely conversions from the orig. metric measurement.

People are fixated on numerical thresholds. Artificially, many may view 9 feet as sounding so much better than 8'11.1" than it actually is, even though there is a scant .9" difference. Similarly, running 100 meters in 9.9 secs as opposed to a flat 10 secs "sounds" so much better despite the tiny difference in times.

As to rounding, some may opt for 8'11" while others will prefer 9'. The exact measurement as listed here leaves no arbitrary wiggle room for personal preference.


The assumption is that Robert was uniformly measured in bare feet and there are photos of a barefoot Robert being examined by doctors, including, I recall, a photo of doctors measuring his arm span.

I don't believe 2700 mm and 2720 mm represent two separate measurements for barefoot and shoe height. Rather, I believe the first measurement was simply an incorrect reporting of the TRUE final measurement of 2720 mm, the latter measurement confirmed absolutely in the Physician's letter without any qualifications.
Editor Rob
One thing is sure...out of bed he sure at one stage could have cleared 9 foot, maybe the only human who has lived (or will ever) and reached that figure.

6'3 Julian said on 21/Aug/20
I love how one of those says 2720 mm, because measuring somebody so tall you can’t compare him to anybody is best done in millimetres. Also give him 9 foot. Making the tallest ever man 8 foot 11 and some inches just seems silly
Editor Rob
I think going with what the Doctor measured is fair, rather than inflating him.

Tall In The Saddle said on 22/Jul/20

8'10.3" along with 439 lbs were first reported in newspapers upon RW's passing. They were described as RW's last recorded stats as per his medical on 27 June 1940. RW's weight had topped out previously to at 495 lbs but toward the end of his life he had lost close to 60 lbs due to ill health. RW was previously ill between the ages of 16 and 17, losing about 50 lbs. This resulted in a net weight gain of only 17 lbs from age 16 to 18 vs a 6" height gain during those same years.

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

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