I am very short in my place(162cm). I need to get up to 175cm to be average, and if everything goes smoothly I will lengthen more.
My tibia is like 34cm long and my femur is like 40.5cm long. I have yet to measure my armspan accurately but since I am an E.Asian it is most likely to be pretty much up there with my height, but at this height I don't even care about being disproportionate.
