I’ve spent a number of years drawing with a manga-spirited style virtually exclusively and while I continue my journey towards flexibility, I have also spent a considerable amount of time trying to study real proportions, sometimes reaching a point where I gather a collection of pictures and make the measurements myself.
I think I’m not alone when I say that I have never thought to look in Wikipedia.
But wouldn’t you know it? It has a neat little list right there.
At the time of posting though, it seems that the article is still being debated upon. No citations. Nothing in-depth. But I can attest that the proportions placed there are consistent with what I’ve read in many books.
Da Vinci’s Virtuvian Man might prove to be something more authoritative though possibly less accurate in realistic terms.
