Well, one thing is pictures, angles, how high I wear shorts, etc., other thing being factual measurements, which dictate that my legs are of normal length (just that proportionally, tibias are shorter than femurs), but actual legs to torso, I get 0.55 ratio, meaning that my legs are not long for by torso.
In regards to comment about 7cm looking "somewhat" proportional; according to the vitruvian man and what I've read on this website about proportions, up to 7cm shouldn't be "somewhat proportional" but actually absolutely proportional, since my wingspan is exactly 176cm (Correct me if I am wrong)
Now, if I were to push past 180, considering my sitting height is 93cm, if I devied 93 by, let's say, 182, I still get 0.51 ratio which is just fine. The only problem I would see is if going above 180 would need to increase the wingspan, hence why I've mentioned possible humerus lengthening should I ever undertake this.
I personally believe, that my torso would be absolutely fine for someone who is 180cm (It's naturally big and broad, so it won't look like a kid got elongated, and is now tall and looks like a stick)
Let me know what you think
