[Editor Rob: there's more people who I've measured but they've not wanted to be in a height challenge. It's useful to have reference heights, I think it helps a bit.]

[Editor Rob: I think the 6ft 1.5 Challenger...holds up pretty well compared to Routh, who has at least 1/3rd inch more hair than challenger 8 did.
]

[Editor Rob: the lowest guess I think is 6ft 2.5, I don't think he looked less than that range. There is more chance 6ft 3 than 2 I think]

[Editor Rob: you can have 6ft 3 people look like routh does aswell beside me, so I can see 6ft 3 arguments for him.]

[Editor Rob: between 192-3cm in shoes is possible]

[Editor Rob: he never looked that tall to me.]

[Editor Rob: 6ft 2.75 isn't improbable]

[Editor Rob: if! I was.

but even if my head was 1 inch forward would it make a difference? No.

Ideally the camera would be 5ft 9 high, so it's in a direct line with the top of my head. This means you can be a few inches forward or further away andhow high I appear in the camera, in relation to the other person wouldn't change much. The lower the camera the more this can effect things. But in this case the camera is about 5ft 5ish range.

Imagine 2 heads side on. If I'm in line side on (same plane) with a taller person (2-8 inches) then the highest point of my head is always going to be further away than their forehead/nose area, the area where I come up to. The line of sight from the camera means the top of my head in a photo might appear a fraction lower than it actually is.

Look at this. From the point of view of the camera lense (it's line of sight), the top of my head will appear at a lower point on the taller person's head than where it actually comes up to (i.e. if the camera was 5ft 9 high).

as for the original point, the topmost point of my head would need to be further forward than Brandon's cheek/nose are to get camera advantage (meaning the top of my head appearing higher up his head than it should).

So for you to believe I'm gaining any advantage in relation to high up my head appears against his, I must be about 4 inches further forward :) In fact, maybe he's gaining a slight fraction advantage over me ;)

you can be directly the same distance from the camera with a taller person and the point on their head at which you appear to come up to, is likely fractionally lower than if you were to raise the camera from say 5ft 5 up to 5ft 9 - to be in line with the top of my head. The illusion can be even more when you have a shorter photographer and you were to raise the camer from 5ft to 5ft 9.

the nearer the camera is to my height the better. Here is a camera 5ft 5ish range high Here, both of us are 3 inches nearer and there's barely half an inch advantage by either identical height person being at least 3 inches nearer when the camera is 5ft 5 range high. If the camera was 4ft 10 high you'd see a bigger difference of course.]

[Editor Rob: he's a physically fit man and pretty strong, but if he was in an arm wrestle with SuperMAMUN he may lose...]

[Editor Rob: between 200-210, he seemed like a pleasant fellow]

[Editor Rob: I'm not sure, maybe in This picture if you look closely you can see the blue background a few mm above the 6ft 2.5 line so unless his skull is blue how can he look 6ft 3 let alone 195cm ;)

I don't think it's a stretch to consider his hair is at least 1/3rd inch thicker than mine.]
