Hello rob, there is someone on tiktok who is figures people height he said ksi is 179.68 cm or 5’10 3/4”

Editor Rob
Height hokage is a good name. I would recommend subtracting 1.15cm for the sneaky lifts KSI wears 🤫

many people on here have also guessed Ksi 5ft 10.5-10.75...sometimes he can look it, so it's never exactly ruled out.
Adam Noakes said on 13/Jan/21
How tall do you reckon KSI is straight out of bed Rob, would 181 be a possibility?
Editor Rob
I think that is possible
slim 6'1 said on 9/Jan/21
I’d say about 179
Callum Barker said on 7/Jan/21
I’d say just over 5’10
Jkiller said on 4/Jan/21
KSI is 5'10.25, no doubt about it.
FriedChicken said on 3/Jan/21
At worst 5'10 1/4 with a chance of 5'10 3/4 at best. 5'10 1/2 I'd give him
Tacticalsmurf said on 30/Dec/20
Rob, in the photo linked below, you can see KSI and Harry (w2s) are stood in a line with the rest of the sidemen and KSI is barefoot while w2s is wearing socks. KSI's chin is slightly high but i think KSI would a solid 1/2 inch or 1 inch taller. Maybe a downgrade for w2s to 5'10 flat and upgrade for KSI to 5'10 1/2 could be a shout or w2s being listed as the same height as KSI maybe reasonable but if anyone edges it, I believe its KSI.

they may well be very close, I wouldn't have thought ksi really was taller though.
Tacticalsmurf said on 30/Dec/20
KSI - 179cm (5'10 1/2)
Harry - 178.5cm (5'10 1/4)

Jake Paul - 180cm (5'10 3/4 - 5'11)
Logan Paul - 187cm (6'1 1/2)
Tacticalsmurf said on 30/Dec/20
SJZL he's 91kg right now but he's looking in amazing shape.
Click Here - 11:38
SJZL said on 28/Dec/20
He's a solid 5'10. 78kg is kinda outdated. He's a lot bigger now at least 90kg
Gonzalez said on 26/Dec/20
I’d give KSI a very solid 5’11 and he might shrink to 5’10 3/4
Lover_thorn3 said on 24/Dec/20
KSI now has a higher average guess than Harry Personally i disagree with that.

KSI- 178CM exactly
Jake Paul- 178.5CM
Harry- 179.4CM
Andy5'93/4 said on 20/Dec/20
If Ksi is 5’10 3/4-5’11 jake would be 5’11.5 range. With ksi wearing 1 inch shoes and Jake being in boxing shoes they looked about the same height. Jake has about half an inch on KSI theres no way KSI is taller than Jake
AB(175cm) said on 18/Dec/20
In my opinion:
KSI- 179-179.5
W2S- 178.5
Tbjzl- 168.5
Vikkstar- 167
Jake paul - 179.5-180
Logan paul- 186-186.5
Callux- 182
Deji- 170-170.5

There’s not a chance he’s taller than Jake Paul. If we bump up KSI we have to bump up Jake a quarter inch to
Master Hunter said on 12/Dec/20
I'm starting to believe Zerkaa is 5'11 3/4
Tee said on 11/Dec/20
the sideman video hide and seek at the beta squad house jj is the same height as harry in the intro and josh looks an inch taller.
Kyam said on 7/Dec/20
JJ is actually 5'11 it's been officially confirmed on his YouTube Channel, He's not 6'0
King G said on 29/Nov/20
It’s time to bump him up, he’s taller than Dana white who you have as 5’10 1/4 as well. He’s a solid 5’10 3/4 - 5’11
Pat m said on 28/Nov/20
He's 6ft in his big shoes and with his hair, he's barely over 5ft10 barefoot
Jabba said on 27/Nov/20
Rob any argument for 5’11?
Editor Rob
some have made an argument he could be that tall, it would be the highest I'd ever think possible.
It's lit said on 24/Nov/20
Click Here Rob is this video they’re all standing together Vikk looks about 3 inches shorter than Harry and Ethan looks about 4 inches shorter than jj, what do you think about this?
Editor Rob
I'd have said Vik was more at Harry's eyelevel there.
sheldon shortt said on 23/Nov/20
needs and upgrade i don’t see ksi under 5’10” 1/2” and with his hair he’ll always look 5’11”
Genau said on 21/Nov/20
5ft10.25 - 5ft10.5 for him would you please add Gus Johnson.
Kiven4663 said on 14/Nov/20
Rob, can you add Zerkaa or josh from the sidemen he claims 6’1 but looks 5’11 3/4 to 6ft rob please add him or respond to my comment it would be good to fully cross off the sidemen fully and hopefully do Tobi after josh
Editor Rob
Zerkaa claiming 6ft 1 is a bit of a stretch really, I think 182ish cm is possible
Tacticalsmurf said on 9/Nov/20
GTB172cm I fully agree. I'd estimate KSI from anywhere between 5'10.5 to a weak 5'11. 100% no lower than 5'10.5 but not any higher than 5'11.

As for the sidemen i'd say the following:
Simon: 6'2
Josh: 6'0 1/4
KSI: 5'10 1/2
Harry: 5'10
Ethan: 5'7
Tobi: 5'6
Vikk: 5'5 1/2
Kiven4663 said on 7/Nov/20
GTB172cm, I know he’s definitely not 5’11 but not a flat 5’10 I think here’s what thier heights are
Ksi: 5,10 1/2 to 5’10 3/4
Jake Paul: 5’10 1/2 to 5’10 3/4
Harry: 5’10
Josh: 5’11 3/4 to 6,0
Logan: 6’1
Simon: 6’1
Deji: 5’7
Joe Weller: 5’8 1/2
Gib: 5’8
Ethan: 5’7
Vidal: 6’1
Ryan Garcia: 5’8
Rob, what do you think
GTB172cm said on 7/Nov/20
Seeing these comments and it’s very hilarious. KSI only claims 5ft11 coz he’s not happy with his height. He clearly isn’t 6ft like Zerkaa said coz he’s 5ft11.5-11.75 and he’s near 2 inches shorter than Miniminter who’s near 6ft1.5 for me. KSI is an inch shorter than Zerkaa, perhaps a weeny bit more. Anything less than 5ft10 is too harsh but he can’t be seen anything more than 5ft10.5-10.75 coz he’s barely taller than 5’10 W2S.
Roots4828 said on 6/Nov/20
Click Here At 6:30 — How tall does the security guard look next to KSI? Looks like a strong 6’8” at least. He was at the Anthony Joshua events too and was a good few inches taller than AJ.
Editor Rob
yeah he looks no less than that kind of height range
Joshbrecker said on 3/Nov/20
Rob, how tall would ksi be in Air Force 1s?
Editor Rob
5ft 11.5-11.75 likely
Lover_thorn3 said on 29/Oct/20
Rob could he be flat 5’10?
Editor Rob
I feel strong 5ft 10 range
Joshbrecker said on 21/Oct/20
Rob, what’s the tallest you could see ksi measuring ?
Editor Rob
5ft 10.5-10.75 is probably the tallest range.
Erik Lopez said on 16/Oct/20
Hey Rob how ya doin?

So see here you’ve listed Craig David at exactly 5’10: Click Here

Then see this tweet here: Click Here

Now we don’t know she difference but Craig isn’t even standing properly so even if he had a show advantage that’d make up for it. So they look pretty much the same. Could it be argued that JJ is legit just 5’10 straight up?
Editor Rob
could be pretty close in height
6'3ozzy said on 13/Oct/20
rob' ksi look 2-2.5 inches shorter than logan paul when jake paul looks 3-3.5 inches shorter
i feel like an 5'11 upgrade for ksi is needed
beast king said on 10/Oct/20
Rob in this video they're all standing in good postures vikk doesn't look that short next to jj Click Here
Editor Rob
could seem between 4-5 inches shy of ksi there, however the ground they are on is a bit iffy, could be adding/removing height from a few of those guys.
recapa said on 8/Oct/20
perfect listing .he is barely shorter than that jake
Joshbrecker said on 28/Sep/20
Rob , yeh he did zerka confirmed on his YouTube channel mini had his legs bent n then claimed he was just under 6’1 and mini was just under 6’3
Joshbrecker said on 27/Sep/20
Rob , look on the sidemen insta most recent post it’s ksi next to the height chart what height would u think he looks there assuming his shoes give him around 1-1.25 inches and being slightly closer t camera ?
Editor Rob
He managed to look as tall as Miniminter did against that height sheet, but then maybe Mini had his legs apart a bit!
Ehsan Jabar said on 24/Sep/20
@joshbrecker zerka confirms in his latest video that Simon was indeed bending his knees on purpose

Also says that Simon got measured near 6'3 and he got measured about 6'1

Can confirm that zerka is around 5'11 and three quarters considering the shoes he wears gives him about a inch in height
TheBat said on 23/Sep/20

I agree that KSI’s definitely not 6’0”. He’s lately claiming 5’11” which isn’t nearly as bad as claiming 6’0”.
Greg said on 23/Sep/20
@TheBat Idk man KSI’s height is irritating, he claimed 6’0 and a bit but when I watched a video of him doing a wonky measurement it seemed he wasn’t far off 6’0 like 5’11 maybe but he had a Durag on so 5’10 range could have been possible but he’s definitely not 6’0.
Joshbrecker said on 20/Sep/20
Rob, at beginning of this video we see w2s stand next to height chart as does Miniminter etc how tall do you think they look Click Here
Editor Rob
I don't know what their footwear was like, but Miniminter came out looking at most 1 inch taller than how w2s did...yet it's obvious Miniminter is at least 2.5 inches taller.

A photo like this of big Niko And the sidemen probably gives a decent idea, well apart from ksi and his wig.
TheBat said on 18/Sep/20
@Cameron Brown

Sorry but KSI isn’t 5’11”. I wouldn’t be surprised if he is a hair under 5’10.5”.
Jackson Roberson said on 14/Sep/20
Rob , what’s the Tallest you’d go for ksi ?
Editor Rob
5ft 10.5 is arguable.
Jackson Roberson said on 14/Sep/20
Rob, who do you think would be taller ksi or harry W2s?
Editor Rob
they do seem very close
Cameron Brown said on 12/Sep/20
The youtuber Chunkz, Click Here is about 6'1.5 to 6'2 next to Ronaldinho who is listed at just over 5'11, Click Here KSI is 5'11 anyone arguing any less is clearly just trying to degrade him and make fun out of him
Pawcio said on 11/Sep/20
He's is shorter then the burnt chip aka Josh Larkin who is 5'10.
Lover_thorn3 said on 11/Sep/20
Rob. Could KSI be 5’9?

Click Here

The guy he poses with is 5’10

Click Here

He looks around 3 inches above ella henderson

Click Here

I believe the guy next to him is around 6’0/6’1?

Click Here

Harry looks an inch above him

Click Here

Looking at these. JJ seems a solid 5’9 to a weak 5’10
Editor Rob
The more photographic/film there is, sometimes the easier it can be to construct an argument for one height or another.

That guy also stood with Bezhinga and joked about being over 6ft! I don't know exactly how tall he is, but yeah he seems taller than ksi, maybe an inch.

Although as we all know Ksi did do his own measurement, but it could have been better. However, there was enough in his clip I feel that you could rule out under 5ft 10 range...maybe

The ultimate measurement is from my own stadiometer. You go under that, you come out knowing your real height 😁

Many have left my house with their tails between their legs or a stride in their step.
5ft11Kyle said on 8/Sep/20
Id say 5'10 7/8 - 5'11 1/4 Range. He faced off with Jake Paul in this video, bareing in mind he had airmax 270s which give 1.3 in, while Jake Paul is wearing flats that give him 1/4 inch.
Click Here
At 4:45.
I have Jake at a solid 5'11 1/2. And JJ looked around 6ft and a bit there facing off at jake. So around 5'11 Range
Rorz said on 7/Sep/20
How tall does Viddal Riley look here with KSI? (middle)

Editor Rob
Could be 2.5 inches taller that moment.
bruhmoment said on 7/Sep/20
Hey Rob! Completely unrelated, how tall do you think Niko Omilana is? He has claimed to be 6'5 in the past which I think it's a bit far fetched. He's looks around the 1.90m-1.92m range, what do you think?
Editor Rob
I wasn't so aware of him, but I just watched that one of him with the racists and he looked a big fella on the street. He claimed 6ft 5 and 4 on twitter, I'd have no problem believing 6ft 4 just from that video!
YordanDamyanov said on 6/Sep/20
Rob, i think he might be flat 5'11, maybe 5'10 3/4 at worst but 5'10 1/4 seems kind of short for him. Seems flat 5'11 (180) guy next to Simon and Harry.

i love sidemen, i watching them since 2015, there was so many guesses about their heights, so i am gonna tell the truth.
simon is - 186-87
josh is - flat 6 foot
harry is - 179-180
jj is - 178-79
tobi and ethan 168-170
vikk is - 5'5 max
Jackson Roberson said on 3/Sep/20
Rob, at 14.45 you see ksi and harry w2s barefoot together standing with good posture maybe an upgrade for ksi or a downgrade for Harry as ksi looks to edge him out here any thoughts?Click Here
Editor Rob
I think they could be very close, Harry did come back out with the 5ft 10 claim, he may well be only that mark.
Jackson Roberson said on 1/Sep/20
Rob , in the video where he measured himself when he draws the mark on his wardrobe how tall did you think he looked I thot he looked 5’11 actually barefoot
Editor Rob
at most 5ft 11.
gio crolla said on 31/Aug/20

Harry 5”10
JJ 5”10.6
Josh 5”11
Simon 6”1
Jay-Jay 5'7 said on 22/Aug/20
Rob can you upgrade him to 5’11.25(180cm-181cm) whenever KSI stands next to W2S who’s 5’10.5 he’s taller than him by 0.5-1 inch. KSI is over 5’10 put him to 5’11-5’12.25.
Jackson Roberson said on 20/Aug/20
Rob, maybe an upgrade to 5’10.5 ?
danile said on 18/Aug/20
i think hes close to 5,11.He's 3/3 of 5,10 so probably a 180.00cm
Jackson Roberson said on 18/Aug/20
Rob, is he taller than Jake ?
Editor Rob
they might be the same height, but taller? You'd need to measure these guys properly.
David 5'11 said on 10/Aug/20
Rob, I’m 16 year old and I try to found out my height. I get two different heights, sometimes 181cm, and other times 183cm. What is my real height?
Editor Rob
We shrink during the day, that could be a cause.
Slim 6'1" said on 9/Aug/20
Jackson Roberson said on 5/Aug/20
Rob, any chance he really is 5’11 like all his friends and him say ?
Editor Rob
how much of a chance? You don't rule it out, but over 5ft 11 I think you can rule that out.
TheBat said on 5/Aug/20
Finally he's stopped claiming 6'0". I still think KSI is around 5'10.25"-5'10.5", very similar in height to me.
6'1Adam said on 4/Aug/20
Rob why are you so reluctant to upgrade him I think he deserves to be higher then this listing he’s looked 5’11 more times then 5’10
Editor Rob
If I saw enough to say 5ft 11 I'd list him at that, I don't rule out entirely of course!
Kinan Abuawad said on 3/Aug/20
many people stated that ksi is 5,11 like Viddal Riley his coach and few of his friends
Jackson Roberson said on 2/Aug/20
Rob, In his most recent video a fan says “how does it feel to be smaller than jake Paul” to which he replies saying he’s taller than jake any thoughts?
Editor Rob
He might feel he's taller?
Jackson Roberson said on 31/Jul/20
Rob, any chance an upgrade to 5’10.5?
Editor Rob
That's a figure that if he was properly measured he might get.

6 foot and a quatre teenager said on 30/Jul/20
Because he isn't a height obssessed person like myself, there is a good chance he will round up if he is like most people. Which is likely, he is probably rounding up to 5'11, and is actually 5 foot 10 and a half
Jim Tyrrell said on 29/Jul/20
He's a solid 5'10.5 but rounds up to say he's 5'11.
Destini said on 29/Jul/20
Here are my predictions for the sidemen
JJ 5'11 I mean he said in the latest vid that hes 5'11 so I believe him althouhg he looks closer to 5'10
Miniminter 6'2
Harry 5'10.5
Behz 5'7
Vik 5'6
Tobi 5'6 3/4
Josh 6'
Tyler Bussier said on 28/Jul/20
I’d say 5’11
Sanjay said on 27/Jul/20
He said he is 5'11 in his latest video
6'1Adam said on 27/Jul/20
Rob he admitted to not being 6’0 but why won’t you upgrade him to 5’11?
Editor Rob
I don't know if he's really as tall as that mark.
Yavian said on 27/Jul/20
Hey Rob, he released a video today and admitted he's not 6ft. He says he's 5'11"
Do you think he may be 5'11.25"?
Editor Rob
Well at least he isn't claiming 6ft any longer.

You could be almost 5ft 11

he aint 6 foot there was a amzon package if you watched the video correctly hes stood on it
Kitbit said on 21/Jul/20
Rob thoughts on JJ’s new video where he measured his height?
Editor Rob
He used nice angles to help his 6ft case!
Thomas Burgos said on 21/Jul/20
On his recent video, he measures himself but stands on a box to reach 6 feet. He most likely is barely 5'10".
6'1Adam said on 21/Jul/20
He finally did it Ksi looks around the 5’10.5-5’11 range rob why won’t you upgrade him?
Jay-Jay 5'7 said on 21/Jul/20
KSI looks 5’11-5’11.5 because he looks 0.5-1 inch taller than W2S
Sank said on 21/Jul/20
Guys he measured at around 5’11” barefoot somewhere there I think but not sure in his latest video

It's a shame he never put an object on his head, then put a pencil mark and showed exactly what height he got. I'm sure he will do a part 2 😆

6’0 and a bit
Faraz Shahzad said on 20/Jul/20
Here’s a pic of JJ next to 6’2 Miniminter. Click Here
He looks about 5’11, probably because of his shoes. I would say JJ is a solid 5’10 barefoot.
6'1Adam said on 18/Jul/20
@Kitbit almost all of his reddit videos his fans keep saying he isn’t 6 feet they even convinced him to buy a measuring tape so we can find out his height for real

@6’1Adam which video does he get called out on?
the name's Sam said on 13/Jul/20
178.5 cm is fair for him excellent average guess though
6'1Adam said on 9/Jul/20
Yep he definitely isn’t 6 feet tall someone just called him out to measure himself on camera and he just said he had no measuring equipment and he’s clearly capable to buy some
6'1Adam said on 5/Jul/20
Rob he only looked 2 inches shorter then 1.88m Emile Heskey and that’s not considering the hair I think he needs an upgrade to at least 5’10.5
Guy66 said on 3/Jul/20
@Chris97 picture? I swear they are the same height
Chris97 said on 1/Jul/20
KSI is a weak 5'11, 5'11 in the morning, 5'10.5 to sleep, wanna know why????, cause he is taller than harry by an inch, and harry is 5'10.
JayX said on 23/Jun/20
Can you guys tell me how he is 5 foot 10 but you have fousey at 5 foot 9... when fousey is clearly taller than ksi when they met each other

it may be time to upgrade fousey
Sank said on 22/Jun/20
@beast king KSI wasn’t wearing shoes in that there was a different angle from above and joe was wearing shoes JJ wasn’t and he was still taller so JJ is probably at least 5’11 barefoot and 6’0 tall with shoes

Rob, Logan Paul claiming to have lost an inch probably means he was always 6’1 barefoot ksi looks two inches smaller maybe closer to 5’11 is best for him !m? I also do see him edging jake
Jackson334 said on 6/Jun/20
@Jack Willis

Harry isn't 5'10.5 though, he's said that he is 5'10 flat
Phrygian said on 5/Jun/20
I still to this day, find it hard to believe that there are 3 inches between KSI and Logan Paul.
Nuson said on 3/Jun/20
look at jake Paul’s vid ksi tried to fight me backstage when ksi comes he looks about and inch taller plus jake was wearing shoes that gave him extra 1.5 inches
Jack Wills said on 2/Jun/20
I think he is 5’11, 5’10 is a bit too low
For the Logan fight KSI was listed as 6’0 which is ridiculous, Logan is about 6’1.5/6’2 and is clearly taller than KSI.
Viddal Riley is around 6’1.5 and is also significantly taller than KSI. So no way 6’0 but I would say a weak 5’11, probably exactly 5’11 and no more or less.
Also compared to 5’10.5 Harry, he is slightly taller than Harry making him 5’11.
Also could you do one of these on Viddal Riley, would be interesting to see your thoughts, I personally think he is closer to 6’2 rather than 6’1.

I thought ksi was around 5’11. But after seeing the video with offset I would now say he is 5’10
David Peter said on 25/May/20
186.5cm 17yearold I thought about the exact same thing. He looked very similar to offset in height I will give ksi 177m
186.5cm 17yearold said on 24/May/20
in his video with offsset he just posted, he actually looks a similar height to him, and he is 5 ft 9
Cameron Brown said on 22/May/20
I love how people say this guy wears elevator shoes just because he worn a pair of shoes 1 time that had tall heels - which weren't discreet whatsoever. In the first weigh in versus Logan Paul they both worn no shoes and KSI looked the 5'11 versus Logan, like he did consistently when they both worn shoes. KSI is 5'11 and there is no way that he's shorter
Boban Linard said on 29/Apr/20
Yeah, KSI often has elevator shoes. He sometimes appears taller than 5'11.5-.75 Zerkaa

Looking a solid 5'11 with Amir Khan (who you have listed as just over 5'8)

Yo Rob I think JJ is weak 5ft11 because I met him after his 2nd fight with Logan Paul and I took a pic with him and I stand around 6ft1 and JJ seemed more the than one inch shorter than me so there's no way he is 6ft if he's 2 inches shorter than me and I'm only 6ft1
Rob WhatchuThink said on 16/Apr/20
I've looked into this a TON and I've seen that he's actually as tall as or maybe shorter than harry when they were playing the pointing direction game on moresidemen and they were barefoot standing next to eachother. KSI now seemed to have got shoes that add more to his height
Innocent O said on 22/Mar/20
Dana White is listed as 178.4cm but so is KSI. Not sure about that Rob?

You could literally see in the sidemen ice dunk tank challenge skip to 19:10 that jj is 1 inch or 0.5 inches taller than harry which is about 5'10 - 5'10.5 same angle no footwear both with their bodies straight which means JJ is probably 5'11 and a weak 5'11.5

Rob, how tall do you think the youtuber Cody Ko is? He claims 5 ft 9 but he looked really small with jake Paul, I thought he was like 5 ft 5 so I looked at some photos and he might be 5 ft 6 7 based on a photo with KSI but he looked similar to the 5ft 9 listed David Dobrik Click Here
Editor Rob
doesn't look more than 5ft 8
Murtuza said on 5/Feb/20
Well, my opinion on this. In the Recent Fight where KSI confronted Jake Paul He did look taller but Jake was wearing flats and KSI was wearing regular shoes. KSI’s claim of 6’0” is clearly not true because beside legit 6’2” Logan he looks way shorter. Even with 6’1” viddal. He generally looks to be a bit short then Jake who claims to be 6’1” but is actually a very weak and barely 5’11” in shoes so my guess would be that KSI barefoot is 5’10.25”
Imzmdudisjss said on 2/Feb/20
@Rob @Markus93 @Michael P @PM
Jake is taller than KSI. KSI was wearing Kyries that add an inch at least and Jake was wearing boxing shoes which are flats basically.

This confirms that Jake is half inch taller than KSI.

Also, KSI is a notorious elevator shoe wearer as exposed by @ksi_is_insecure on 22 July 2019. So please stop overestimating his height as anything over 179 CM.
Michael P said on 2/Feb/20
I would give JJ no more than 5'11.5 or 6'0

Jdndidididi said on 2/Jan/20
Not only is he wearing shoes I that picture but measuring heights like that is very inaccurate anyway.

His height has been debunked several times. I don't know why people are still deluded enough to think he's anything over 5'10.5". Just scroll down to 22nd July 2019 comments and read what @Ksi_is_insecure wrote.
`Leo34 said on 2/Jan/20
I think he is 5'11.5 because one guy in ksi's reddit measured ksi's headphone and then ksi's head ksi's head is 8.95 inches then he measured his hbead to his whole body his body was 8 head s of his so that means 8.95 x 8 is 71.6 then he listed jj as 5'10 but that is a lie Click Here

71.6 inches is 5'11.5 but if you calculate it it doesn't work but if you calculate 72 inches it equals to 6 ft so if 72 inches is 6ft that means 71.6 inches is 5'11.6

so in conclusion in the mourning ksi is 5'11.5 but to bed he is 5'11
luke89 said on 1/Jan/20

No he isn't. He's 5'10 range. Mini said that because he claims 6'2. In reality he's like 6'1. There is 3 inches between KSI and Mini.
Bobby Brown said on 15/Dec/19
I think he’s in between 5’11 and 6’0 a case could be made for either or the people who spend time with him everyday like Miniminter Viddal all say he’s 5’11

Photos do lie. Camera angles, lighting, footwear, how long the people have been on their feet etc. make a difference.

And even if photos don't lie, people do lie. You seem to be one of those people. You seem to be completely deluded about your own height. KSI is nowhere near 6 ft. Look at him next to a weak 6'2" like Logan Paul and then compare him to yourself. You'll see the difference.

His reach probs changed cos the 71 inches was accurate with his height if he's 5'10 his reach is most likely to be 5'11(71 inches) or there about the increase is probably to suit more with his inflated 6'0 claim .

@harvey567 cmon u can't seriously think Deji is 5'9 ,He's like 5'7 ...a weak 5'8 at best Weller is more around 5'8 and he's taller than Deji ,JJ looks around 5'10-5'11 at times but more or less looks 5'10 range most of time around same height as harry(w2s) and about half an inch to an inch shorter than sensei just depends on footwear and posture and closeness to camera
I also think ricegum is over listed on here as if he's 6'0 then how is he 2 inches shorter than Vidal Riley who's around 184cm also can't see Logan Paul taller than minininter mini gives off a much taller lanky impression than Logan .
Harvey567 said on 29/Oct/19
I think he is around 5'10 3/4 to 5'11 1/2 its just because when he stands next to faze sensei he looks shorter but his posture is just not straight and logan is taller than him in just 2 inches and his brother deji is 5'9 5'9 1/2 and jj is taller than deji

Honestly he looks a very strong 5'10. I'm going borderline 5'11. Next to 6'2 logan paul he looks about 6 foot. Think he needs an upgrade Rob or downgrade Logan to 6'1 flat or just a bit under it. He makes 5'10 look really tall

Just saw his press conference before the upcoming fight against Logan Paul. He was listed there as 6 ft. Must say that is a ridiculous claim, KSI is at most 5 ft 10 ½ (179 cm). Can't see him above that.
Skeletor Mode said on 2/Sep/19
His hairstyle makes his height a bit tough to pinpoint but, based on many photos of him in the comments he's clearly at least 5'10". His claims of standing in the 5'11" - 6'0" range are definitely out of the picture though. 5'10.25" is probably the best listing.

8jsv8jvs8 said on 4/Aug/19
@Cameron Brown

It's okay if you have a crush on KSI but he's 5'10" at best. W2S might not be 5'10.5". I don't know why he's listed as that when he himself said he's 5'10".
Pop Kek said on 4/Aug/19
@Cameron I posted this on Mini's page but I'll post it here too...

My opinion on the sidemen's height:

Vik: 5'6
Josh: 5'11 3/4 - 6ft range. Sometimes looks 5'11 1/2 next to KSI.
JJ: 5'10 1/4 - 1/2 range 
Simon: 6ft 1, max 6ft 1 1/4
Ethan: could be 5'7 - 5'7 1/4
Harry: same height as JJ
Tobi: maybe 5'6 3/4 or 5'7, something like that. Similar height as Ethan. A tiny bit shorter than him.

This were my older estimates. I'll see if I change some now.
Let's start with the easier ones to guess first:

Ethan: 5'7 (He said in "Who knows Ethan best" video that he's that height so we are correct about that.

Vik: 5'6
Tobi is a little bit taller than Vik and shorter than Ethan. I'll give him 5'6 1/2

Now it's the more complicated ones because in some some videos and photos they look one height, in other, different heights.

JJ: 5'10 1/4
Harry same height as JJ

I agree that sometimes he looks shorter than JJ but you have to keep in mind that when someone is really close in height (like a cm) with shoe disadvantage and bad posture (Harry tends to have a more relaxed posture) you can look shorter. In more videos I've seen (don't remember them) when Harry stands more straight, you can immediatelly see a difference in height if you have some knowledge about that (almost everyone in this site does, so it won't be a problem)

This is why I think they are identical or if not only a cm difference. I myself think they are the same but if they really are a cm difference, I would give it to JJ because he has somewhat better posture in their newest videos. That's what I can see from my eyes. A stadiometer will say the correct thing.

Now about Simon and Josh...

I am almost positive he is a true 6'1.
Josh is more tricky because he looks different height in videos. Sometimes looks 5'11 1/2 sometimes 5'11 3/4 and 6ft. In their newest video he looks 5'11 3/4 and I will give his height there cause he manages to look that the most in videos.
TDM said on 29/Jul/19
@Cameron Brown

Do you have a thing for JJ or something?

I've got to admit in what you've posted when they are all barefoot he does look taller, but I don't think that changes JJ's height. I think Harry is actually less than 5'10" and that JJ edges him, because JJ is a true 5'10. I think Harry could easily be 5'9", because he wasn't much bigger than Connor McGregor in the photo of them.

The Sidemen are so hard to judge to be honest. Vikk, Tobi, and Ethan are easy to judge, because Ethan is straight up and honest about his height and I respect that, which makes deciding on Tobi and Vikk easier as they are slightly shorter than him. I think Josh is 5'11.5", but definitely not the 6'0" that he's been claiming recently. Simon has been wearing some HUGE shoes in all of their recent videos, so I don't think he is the 6'2" that he claims, because he isn't loads taller than Josh in the most recent baby video even though he's in massive trainers and Josh is barefoot.

You have to take all their heights into perspective when trying to work out JJ's. If JJ is taller than 5'10" then Josh must be 6'0.5" or 6'1" and Simon would be 6'2" or 6'2.5", which just isn't true.

My guesses:
Vikk - 5'6.5"
Tobi - 5'7"
Ethan - 5'8"
Harry - 5'9.5"
JJ - 5'10.25"
Josh - 5'11.5"
Simon - 6'1" maybe 6'1.25"

@"ksi is insecure"
You could be right that he wears some sort of elevator shoes.. I've noticed it too. He definitely looks taller in todays videos than older videos. I'm not convinced he's 5'11, more 5'10.25-5'10.5 range.

Everyone has the right to wear whatever they want though, elevator shoes or not. If that makes him comfortable, it's fine..
Cameron Brown said on 24/Jul/19
Rob, can you just delete this accounts comment under the name "ksi is insecure" he literally is just hating on KSI and trying to make him seem insecure for no reason. He is not wearing 3-inch elevator shoes haha. KSI never really stands up straight so I would argue he is not bothered about height let alone insecure about it. He is taller than wroteshaw and that is a fact Click Here
start of the video all have no footwear KSI is taller
KingSerph said on 23/Jul/19
@TheBat I've been saying the same thing for so now long on here, rob you need to consider this.. there's no way harry is 179-180 he's gotta be 177-179 at his very best nothing more than that considering all the other pictures of him with guys like ksi and miniminter.

He does. Either KSI really is or he's trying to make himself tall with big footwear/lifts.

@Cameron Brown
No, he is not. He is insecure and he wears elevator shoes.

He is nowhere near 5'11". He is 5'10" at the very best.

Here's all the proof.

He is just slightly edging out 5'8.5" Conor McGregor. And he looks just about shorter than W2S (5'10.5").

And this is KSI wearing his 3 inch elevator shoes to hide his sub 6 ft height compared to W2S who isnt insecure in himself.

He is 5'10" at the very best.

Not to mention, his trainer, Viddal Riley is 6'1" (according to himself) and this is him compared to KSI.

Is this a 1 inch difference? Hell no.

However, this dude is so insecure about himself that he bought himself several pairs of elevator shoes. And this is what he looks like now compared to Viddal in his new shoes.

Just lol...

Just to add salt to the wound, this is him standing barefooted next to a weak 6 footer (5'11.5"), Josh. Notice, how he is dwarfed.
Click Here

However, Mr Insecure wears his elevator shoes 24/7 now. So this is him compared to Josh in his new shoes.

My point is proven. He is 5'10" if you're being lenient. His brother (5'7") is equally as pathetic, claiming 5'10" but unfortunately he's not smart enough to realise he needs to wear elevator shoes to look that height

he is taller than wroteshaw (w2s)
Aabid said on 7/Jul/19
It actually annoys me so much that he believes he is 6ft tall, I know for a fact he is 5ft10 3/4 maybe touching 5ft11
TheBat said on 20/Jun/19
More the I look at KSI, I think he maybe 5’10.5”. JJ looks like that height in more recent videos.
Abdoox said on 18/Jun/19
178 cm 5ft10 is ksi no where 6 ft 183 cm as he claim.
cmillzz said on 14/Jun/19
177cm I can definitely believe.
Serph king said on 25/May/19
Anyone can explain to me? How these lads (ksi,w2s) were barely any taller than 5'8.5 McGregor?
Serph king said on 24/May/19
I would say ksi is like 179.1 during the day time and shrinks to 177.2-5 till the bed time this guy just dont give me an impression of being a 178.4 till the time he goes to bed
Greg said on 9/May/19
@Tall Asian yeah but it doesn’t stop there 6’2 guys think they are 6’4/6’5. And even guy 5’8-5’9 think they are between 5’10-6’0. I think KSI could be a weak 5’11 if that guys 6’0.5 he looks to be 2 inches shorter.
Greg said on 9/May/19
@The Bat I would be surprised if he was 5’10.75” more like 5’10.25-5’10.5”
TheBat said on 7/May/19
@Tall Asian

Deji is really bad at that but so is Jake Paul. He claimed 6'2" but is 5'10.75" best.
Tall Asian said on 4/May/19
He is probably the 2nd worst height frauder in the YouTube community after only his brother, Deji.

He claims to be 6'0" and he wears shoes that add 3+ inches like these to look close to Viddal Riley (self proclaimed 6'1").
Click Here

Yet he's actually a clean 3-4 inches shorter:
Click Here

It amuses me that literally everyone between 5'10 and 5'11" claims to be 6'0" while everyone between 5'11" and 6'0" thinks that they are 6'1".
TheBat said on 18/Apr/19
If anybody still thinks JJ is 6'0", well here he is with 6'0.5" Michael Bisping, KSI clearly isn't 6'0" at all.

My current guesses for all of the Sidemen heights.

Miniminter: 6'2"
Zerkaa: 6'0"
KSI: 5'10.75"
Harry: 5'10.5"
Ethan: 5'8.25"
Tobi: 5'7.5"
Vikk: 5'6"

Rob you need to do chunkz and Niko omilana. Chunkz for starters has come out and said he's 6'3 which is an outrageous claim in my opinion when he's about an inch taller than 5'10 KSI and around an inch shorter than giggs whose 6'1 (even on this website). What makes matters worse is that he's claiming he's an inch shorter than Niko omilana when you look at all the times they are together the eye level difference is 2-3 inches which makes his 6'3 claim ridiculous. In addition to this Niko omilana is a slightly taller than 6'1 and a half Logan Paul( from the time he did a video on him and Jake Paul when they fought in the boxing match). I think chunkz is the most insecure out of their like YouTube group about their height because it's obvious he's 5'11 or 6'.
Editor Rob
Chunkz looks reasonably tall with the public, I checked and saw he claimed 6ft 1, 2 then 3...he could be 6ft 1 range.
Josh payne said on 13/Mar/19
I am going to try and accurately do all sidemen heights
First off I do actually see miniminter as a full 6”2 guy as there is a bigger difference in height between him and KSI than Logan and JJ
Tallest to smallest:
Miniminter:188.5cm or 6”2,1/4
Zerkaa:184cm or6”0, 1/2
Harry:180cm or 5”10,3/4
JJ:179cm or 5”10, 1/2
Ethan:174cm or 5”8,1/2
Tobi: 172cm or 5”7, 3/4
Vik: 168cm or 5”6, 1/4
Rob thoughts?
Ran magee said on 12/Mar/19
Rob,is Jake Paul taller than Ksi ? And Tbqh if zerka is under 6 feet and around say 5'11.5 Ksi normally looks 1-1-25 inches shorter I think Ksi knows he's not 6 foot but in shoes is 5'11 or so and just rounds up Tbf a lot of people do do this especially with the ego he has probably has convinced himself he is 6'0 in a video with theburntchip Ksi claims he's taller than him and they go back to back and theburntchip is a little taller unsure how much though and this is barefoot chip claims 5'11.5.
Editor Rob
I think Jake has an edge over KSI.
Cameron Brown said on 21/Feb/19
The stadiometer point that someone made was just a complete lie, honestly disappointed in Rob for not finding that out by doing a simple search. KSI has awful posture hence why he can look very short he must be at least a weak 5'11
Click Here
With KSI standing up with good posture he looks no more than 2.5 inches shorter than Logan Paul with very similar footwear
Editor Rob
I'm just laughing at the idea of somebody running away from the stadiometer.

Nobody should ever fear being measured.
XxShadowKnight said on 16/Feb/19
@Daniel Deguara You’re bringing up a stupid point. The reason that Joe Weller looked the same height as KSI is because Joe was wearing shoes that lifted his height by at least an inch, while KSI was barefoot. Joe was looking up (which makes you look at least an inch taller), while KSI was looking straight. KSI is at least 2 inches taller than Joe Weller and he is not under 5’10”.
Daniel Deguara said on 12/Feb/19
Click Here - KSi

skip to 19:32

Ksi is standing next to joe (5'8) and looks the same height, ksi is no way 4 inches taller, he is around 5'9 - 5'10
Connordee said on 11/Feb/19
Ksi's 6'0 claim is ridiculous he's somewhere between 5'10-5'10.5 in shoes can probably pass off as 5'11 maybe a little more but never 6 foot
Alexwatson6ft said on 7/Feb/19
There is a video of his formerly trainer Viddal Riley wanted ksi to messure his height, but ksi got scared, and ran away, that pretty much proves it that ksi is under 6ft.
Editor Rob
Running away from a Stadiometer 😂😂
Aden said on 7/Feb/19
He's a high 5'10 in the morning and a high 5'9 at the end of the day. I met him in person.
TheBat said on 7/Feb/19
@Seth good

KSI isn't 6'0", he's like 5'11" at the most. Probably 5'10.75" at the least.
Seth good said on 3/Feb/19
KSI is 6ft, he looks 2 inches shorter than 6ft 2 Logan Paul, and hes about the same height as Mike Bisping
olliewolff said on 17/Jan/19
I don't think JJ is this short, In a lot of videos he looks the same if not slightly taller than W2S who is listed at 179-180cm here.
