Wingspan To Height & Tibia To Femur Ratio

Edit Post

My height is 173 while my wingspan is 184. My shoulders are also quite wide, everyone notice that in general.
(my morning height is 173 while at night time close to 172)
So, considering wingspan is just only about aesthetics right? to make proportions look good? or, is there anything/any study showing lengtening must be proportional with wingspan?

Here are my stats :

Femur length : 42cm
Tibia Length : 35cm
Sitting Height : 87cm


I'm considering 8cm on femur, however, i've read that tibia/femur ratio must be 0.8 to get long term healthy knee/hip. What should i do? Would 8cm on femur too much?

how about femur/tibia ratio? my femur already a lot taller than tibia. is it a problem?

nope, not x-ray, i've used this videos, which is taken from studies



i just found that 0.8 ratio from some studies, but i don't know particularly which is ok, which is not.

"just try not to go past 1:1 aka tibia and femur equal length and you should be good"

well, it's not that to begin with. i'm kinda worried about it, to be honest.
