My uncle is that height with a sitting height of 88cm so I can tell you that while it is not the average sitting height of somebody that height, it very well does exist. I would not get too worked up about sitting height, wingspan is the important thing to consider before getting this done.
Although wingspan is the onliest SIGNIFICANTLY important matter for the procedure, my wingspan is pretty bad for my dream height which is 185cm.
My wingspan is 180-182cm, but the only reason why it is above 5'11 is that I have damn huge hands (huge body and huge fingers). Like my forearm seems like a tiny piece of crap.
So, it makes me think of the possible worst cases after the procedure when I become 185cm with 2 surgeries proportionally. So I don't know what to do, go on femurs and be 180cm from 173-74? I don't think I'd be happy with it since my tibias already seem to be short. I definetely need 2 surgeries but it's risky as hell..
Yeah I don't know what to do..
Best Regards
