I’ve met Calum in person at a Starbucks. I’m 6’2 1/8 in the morning and 6’1 3/8 at absolute low. We had similar footwear and he was absolutely ~1/4 inch taller than me.
Rampage(-_-_-)Clover said on 26/Nov/23
Yeah I think Calum should get 6ft1¾, probably would edge out prime Arnold....similar to Eddie Hall
berta said on 27/Sep/23
yeah in the video he was measured 6´3 but lets say it was only 6`2 1/2, he still was in shoes that only give half inch. I cant see this guy under 6´1 3/4. Taller than peak Arnold for sure, edging out peak Jim carrey and WIll smith.I think he is close to the 6´2 he claims. I mean Eddie Hall was measured 189 in shoes and he had shoes that gives just over 1 icnh. They should get eath others listings. coullum is talller than Eddie.
Rampage(-_-_-)Clover said on 21/Apr/23
Schwarzenegger (prime): 186.5cm
Von Moger: 187.5cm
Jawilder said on 17/Apr/23
def possible it could just be a bad angle
Jawilder said on 17/Apr/23
If you look at 3:56 where Eric Kavensky measured him, he looked maybe just over 6’1 in shoes.

Johan 185 cm said on 8/Apr/23
Looks like he was an honest guy. Got measured at 6'3 in shoes by Eric Kanevsky on youtube. Same clip Eddie Hall got measured at 6'2.5" in shoes.
So he is an inch taller than Eddie.
Rampage(-_-_-)Clover said on 18/Mar/23
I think 186.5cm is still ok for Arnold while Callum maybe a more solid 187cm? Not sure about the full 6ft2.
O’Hearn is over 6ft2 easily.
183cmErzhan said on 15/Mar/23
he is 6 feet i saw a video where he was measured
berta said on 26/Jan/23
i just cant see him and arnold being the same height at peak. I think calum have half inch on arnolds peak maybe even more. arnold 186 but oculd be 186,5 and calum the full 6´2 before a workout.

I can see that easily for bumstead 👍
Space said on 12/Aug/22
also, 270lbs I meant for Bumstead when I met him
Space said on 11/Aug/22
Ohearn: 6’2.5”
Calum: just about 6’2”
Bumstead: 5’11 7/8
Space said on 11/Aug/22
and my guess for Mike Ohearn now goes up to 6’2.5” easily
Space said on 11/Aug/22
@al001
and I take back the 265lbs guess for him, after just watching the older video of him being weighed-in at 262lbs, I can safely say he was much more yoked and closer to 280lbs when I met him.
Space said on 11/Aug/22
@al001
Cbum looked 5’11 7/8 - 6’0” to me.
Space said on 11/Aug/22
I met Bumstead recently and I was a good 1.5” or more taller than him. I’d say he’s 6’0” 260lbs.
Von Moger looks about the same height difference with Bumstead that I looked with him, maybe a hair more.
Legit 6’2” for Von Moger. Average guess is a little too low for him.
al001 said on 2/Aug/22
Actually disregard the note I put in my last comment 😂. After some thinking I bought another steel tape measure and this one works fine, turns out my old one was a tiny bit dislodged from the tiny metal frame at the base, that explains it lol.
Still think Bumstead is 6’0 flat or a shade over.
al001 said on 21/Jul/22
I believe Chris Bumstead is probably a little over 6'0, like 6'0 1/4.
Click Here
At 1:57 he gets measured with a steel tape measure (but maybe not stretched out all the way just my opinion, or at least not how i always get measured with me busting half a gut lol). Is like 6'1 on the dot with shoes on that give him around .75-1 inches by my estimation.
Morning height would easily be over 6'0 from the look of it, and judging from with other fitness guys. He's always a solid margin taller than barely 5'11 Christian Guzman, a good 2 inches shorter than solid 6'2-2.5 David Laid, and around 1.5 inches shorter than Calum.
Also, those tape measures have been off by .5 inches in my experience. I've used them to measure household things like bookshelves, refrigerators, doorframes, etc. and my steel tape measure measures them half an inch shorter than their manufacturer listed height whereas my cloth tape measure is bang on accurate. Just a note.
Space said on 7/Jun/22
Ohearn looks somewhere in the 6’1.25”-6’1.75”
Callum looks 6’1”

Have you not been following the recent news about him? Concerning him chasing people with a machete, butchering kangaroos, taking videos of children without their consent and making fun of them…This is extremely shameful behavior.

Ohearn is a weak 6-2. Peak he wasn’t over 6-2. Callum looks more 6-1.

OriginalAnon said on 18/Mar/22
Knowing Mike O'hearn is 188 cm you can see that Arnold was around 183-184 peak.
OriginalAnon said on 18/Mar/22
O'Hearn is 188cm at best. Gunn looks like he has lost some height. I don't think he has a full two inches on O'Hearn. At least not these days.

Rob, could Mike O'Hearn get a page?
Jeick San said on 9/Feb/22
However Rob guess Billy Gunn might be 6'3.5 nowadays so Mike O'hearn could be 6'1.5 range. Knowing this info Calum might be 6'1 to 6'1.25.
Jeick San said on 9/Feb/22
Last video from Mike 0'Hearn's channel posted 2 days ago with his friend Billy Gunn Listed 6'4 (193 cm)
Mike O'hearn is clearly 2 inches shorter than Billy Gunn. So Mike is 6'2 max

Fosho0 said on 9/Nov/21
6’1 Calum
Eusebiu - 6'1" (185 cm) said on 24/May/21
First of all, Calum can be easily compared with Arnold in his prime because their physique and height are very similar.
Secondly, both claimed 188 cm and we all know that is not the case beccause that might have been their morning height after waking up and not their afternoon height.
Moreover, I see them both in the 186-187 cm range and I also think that Calum's listing is spot on.
ALEXIZ/180cm said on 8/Apr/21
187 cm
carlospe said on 23/Feb/21
This guy is a legit 6'1.5 guy. Arnold was never as tall as this guy. Arnold looks like his peak was maybe 6ft0.25-6ft0.5
Rampage(-_-_-)Clover said on 7/Feb/21
Bradley Martin I think might edge him so I give him 6ft2 flat
Rampage(-_-_-)Clover said on 7/Feb/21
He looks near 6ft2, this mark is the shortest
Seth da 6.05" said on 5/Feb/21
Rob can you please add Chris bumstead?(classic Mr.olympia) He claims to be 6.1" but seems nowhere near it with guys like Calum and David laid who is atleast 6.2"
There are many videos... He seems 5.11.5 at best...
Janbannan said on 14/Jan/21
Seems accurate 186-187

Jeff Seid 5'10
Calum Von Moger 6'1
realone1 said on 25/Sep/20
Pretty accurate Rob. Arnold could hit this mark
Busting a Gut in his peak but Calum von Moger is a legit 6'1.5 guy. Arnold was probably 1/2 inch shorter 6'0.75 range. I clearly see Calum taller than a peak Arnold
Rampage(-_-_-)Clover said on 11/Jul/20
Calum might be the more solid 187cm guy compared to 70’s-80’s Arnold
holyman175 said on 3/Jul/20
@Rob.I guess Calum is a strong 186 guy while Arnold was more 185 but I'd say a weak 185. A young Arnold doesn't look as tall as Calum. Don't you agree?
Jam Cherry said on 22/Jun/20
I’ll go with 187 cm cause he is very tall indeed
jerton179 said on 3/Jun/20
@Rob do you see a peak Arnold as tall as Calum?
Editor Rob
I think they'd be close if measured
counterman said on 15/Apr/20
Jkiller said on 28/Feb/20
Bradley Martyn was his friend and he always claims 6'3. The guy looks about 6'2.5 and he was a good inch taller than Calum.
I know all this info because I usually watch his youtube channels.
counterman said on 15/Apr/20
Jkiller said on 28/Feb/20
Calum is 6'1.5. Rob's listing is perfect. Legit 6'1.5 flat. I'd go witrh 6'1.25 solid 186 cm guy
counterman said on 15/Apr/20
Jkiller said on 28/Feb/20
Listing is perfect. @Rob is accurated. Mike is like half an inch on Calum. How ever last year I watched on youtube a video from the 90's where Mike O'hearn was measured before the competition. The guy said Ok 6'2 and 240 pounds. This was at 6 pm so Mike is probably a legit 6'2.5 all morning and mid when he trains.
Jkiller said on 28/Feb/20
Look at the video with him and Mike O'hearn, Mike is definitely close to 6'3, but Calum legit looks very close to his height. So he's minimum 6'2, could even argue he's 189cm. Please upgrade his height Rob
Rampage(-_-_-)Clover said on 11/Feb/20
Calum Von Moger - 6ft1¾(187.3cm)
Mike O’Hearn - 6ft2½(189.2cm)
Still not ruling out 6ft3 for Mike though
Aldebaran said on 21/Jan/20
Rob, please change it. Calum is a strong 6'2 guy. 😧
Jkiller said on 16/Jan/20
Honestly looks around 6'2 (188cm). Looks about only 2cm shorter than Bradley Martyn who I'd say is a perfect 190cm.
l4issa said on 8/Jan/20
@gusgiga I see Calum in person and i'm 5'11, and for me look 4 inches difference between me and he.
Solid 6'3
Terminator2020 said on 8/Jan/20
6'1 is a joke. He looks 6'3 and half for me and 6'2.75 just at bad posture
Aldebaran said on 8/Jan/20
Maybe just 6'2 at night. He is honest about height.
Aldebaran said on 6/Jan/20
Look for me a weak 6'3 guy. So 6'1'5 is a Joke for Calum, in the worst scenario 6'2.75(1,89)
Gusgiga said on 5/Jan/20
Rob, i'm Brazilian and i see in person that guy on the side of Calum. Italo Ridney is 5'9. And Calum looks more than 5 inches more taller in that photo.
Calum is a solid 6'2 and next to 6'3.
Gusgiga said on 5/Jan/20
He is exactly 6'2.75 (1,89m) the guy on the side of him in that photo is a Brazilian bodybuilder. And he is measured like 1,75m(5'9) in IFBB competion. I have a official measurement to show for you Rob.
Rampage(-_-_-)Clover said on 4/Jan/20
Ok, 183cm is a joke for Calum...more so than 190cm
Ema said on 2/Jan/20
Calum is max 183cm considering Karina Elle is 177cm.
Rampage(-_-_-)Clover said on 18/Dec/19
If that’s you’re opinion, actionboy...I respect it but I still think he’s close to 6ft3.
actionboy said on 17/Dec/19
@Rampage(-_-_-)Clover
Well I'd go with 6'2.25 range and max he is weak 6'2.5 guy. Over 6'2.5 is too tall. I usually watch his videos on youtube and following him sinc 2014. My guess is a solid 6'2.25 guy. I'm talking about Miker O'hearn who is about 1 inch on Calum Von Moger
Rampage(-_-_-)Clover said on 16/Dec/19
Actionboy Terry Crews is that range O’Hearn was easily taller than him
Johan 185 cm said on 16/Dec/19
Would have been hard to tell them apart when Arnold was at his peak.
Arnold measured this at night on a stadiometer back in the 70's. Vince Basille did the measurement after challenging him, Vince was no Arnold fan. 6'0.5" is impossible for 70's Arnold.
I think that Mike O'Hearn is being reasonably honest, I watched a clip where he was training with Thor ( the mountain) and he only looked around 5 inches shorter. Rob has met Thor and has him listed at 6'7.75".
So its possible that O'hearn is 6'2.5-6'2.75" and rounds to 6'3". Thats pretty honest especially considering Mike's ego :)
actionboy said on 14/Dec/19
TheBat said on 13/Dec/19
Stop with Zyzz. He was max 6'0 guy maybe just 3 inches taller than his brother chest brah who is 5'8.5. 6'1 and 6'2 is a joke for him. He was not an example maybe for those kids and young newbies who don't have personality.
actionboy said on 14/Dec/19
@Joeby33 yes I agree you I'd say the highest prime 6'1-6'1.25. I see 6'1.5 too hight maybe at morning he was that tall or
Busting a Gut like probably he did
actionboy said on 13/Dec/19
Mike O'Hearn very consistent with his claim. 0:45 second. He says " I'm 6'3" but I know he is rounding up.
Click Here
He is a guy who likes to exaggerate in some occasions about his strengh and young days in the gym. Overall he is not far to be 100% honest on is height. He is probably 6'2.25 barefoot and that's what he actuallty looks. If you watch some Mr Universe video on his younger days in the 90's he is always listed 6'2 and 240 range pounds.. However I know your height can decrease almost 0.5 inch when you get measured on that body fitness shows because some athletes are not hydrated during a whole day and some has been dehydrated for a long time.
He is massive and muscular and some guys can look taller but Mike O'hearn in my opinion is a strong 6'2 guy barefoot and I'd say 6'2.25 6'2 3/8 at best 188-189 guy.
Joeyb33 said on 13/Dec/19
@actionboy I’m 2019 I’d say lowest possible for Arnold would be 5 foot 10 and highest 5 foot 10.5. For a prime it’s hard to speculate since I only met him in 2019 but I’d say 6 foot 0.5 for my low prime with 6 foot 1.5 the absolute high prime. I think he’s a little over 5 foot 10 now and was 6 foot 1 back in the day.

For the record as most intelligent know him and O’hearn are big time juicers so looking like this is actually quite damaging to their health. He’s 6-1 imo.

I've read you said Arnold is about 5'10.25 nowadays and saw your photo with him. Ye really looks 5'10.25 any chance you think was 6ft0.5 prime? Honestly I still see hard 6ft1 barefoot for Arnold but 6ft0.75 is the highest mark I'd go..

A friend of mine met o'hearn befor and told me he's about 4 cm shorter than him and my friend is 191cm , so i think o'hearn is 187cm
Arch Stanton said on 6/Dec/19
I saw the documentary on him a few years back. He has the features of a slim, toned guy, didn't look a guy who would be a naturally bulky bodybuilder type. Still, he looks a lot better aspiring to the old school bodybuilders and aesthetics rather than today's freaks.
Johan 185 cm said on 6/Dec/19
6'1.25-6'1.5"
Joeyb33 said on 6/Dec/19
@beacher2 yeah I feel Arnold must’ve been around 6 foot 1 peak. If he wasn’t 6 foot 2, I don’t see how he could’ve shrunk to where he is today.
actionboy said on 6/Dec/19
Mike O'hearn is not 6ft3. I'd go with 6'2.5 max. I saw another video where he looks 6'2. The guy has a perfect posture at 50. He is like superman his strenght is out of this world and he is 50.

That's great info dude. Saying Calum was slight taller than a prime Arnold you mean like half inch I guess right? So you believe Arnold was never over 6'1 barefoot as me and many folks :)
Joeyb33 said on 5/Dec/19
I think Calum is right about where Rob has him. His boots made it hard to tell but he was definitely a large guy. I think I might have been slightly taller than him and he was likely slightly taller than a prime Arnold. I met them both the same day actually which was pretty cool.
Miss Sandy Cowell said on 5/Dec/19

@Rob yes he claim 6'3 but I've seen he was listed 6ft2 in his Mr universe competitions. You can see ol videos descriing the athlete weight and height and it says 6'2 247 pounds in some.. Overall he does look taller than Calum and he is 50. He probably is a legit 187.88 guy 6'2. Calum maybe 6'1.25 barefeet

I wouldn't have thought flat 6ft 2 for him

Is the other guy about 5ft 7 then?
Editor Rob
He can look that range

@Rob. What's your guess on Mike O'hearns height? He is a relly big dude. Bigger and stronger than Calum and he is 50 years old! I think he is a solid 6'2 guy 188 cm Mike O'hearn
Editor Rob
Claims 6ft 3 but I'm not as convinced he is that mark.
actionboy said on 5/Dec/19
@Joeyb33 Interesting you met Calum. So you are 6'2.25 barefoot right? What's your guess on Calum's. Do you really think he is over 6'1.5? You look taller seeing angles and shoes.
actionboy said on 5/Dec/19
Calum's height 6ft 1.5 might be the most I'd go more like a solid 6'1 guy. I think he is not over 186 cm. 6'1.5 might be his morning height. In my opinion his height is pretty like Arnies peak. Overall I guess Calum is 1.5 cm 2 cm max taller than Arnold's peak.
Calum 186 cm 6'1 1/4
Arnold 184-185 cm 6'0.5-weak 6'1
Rampage(-_-_-)Clover said on 4/Dec/19

You guys look basically the same height.
He has to be 6'2 at least.
Rampage(-_-_-)Clover said on 3/Dec/19
6ft2 is debatable aswell for Callum. I think Bradley edges him so strong 6ft2 for him. Zyzz I think was at least 6ft1. Allegedly there’s a video out there of him measuring himself 186-187cm
Caldonio said on 3/Dec/19
Has claimed. 6-3 on occasion. ??? Looks 6-1.

Yay finally! Never really been able to pin this guy down, haven't watched to much of him recently. Always thought he was somwhere in the range 6ft1.5-6ft2.5. Tbh I was a little suprised by this listing, thought he may be a little higher, although he has seemed potentially under 6ft2 in some recent pictures. David Laid, Connor murphy, Bradley Martyn and Dom Mazzetti would all be interesting adds of around the same height. My guesses for them are:
David Laid: 6ft2.5
Connor Murphy: 6ft2
Bradley Martyn: 6ft1.75
Dom Mazzetti: 6ft0.25
Animus said on 2/Dec/19
What a coincidence that he's the same height as a prime Schwarzenegger. Von Moger definitely looks above 6'1 and can occasionally pull off 6'2.
