Sorry it's a bit big — I did the pixel measurements on it raw and they'd have been all wrong if I'd shrunk it. Of course, I could have shrunk it then done the measurements again, but that would have denied my basically lazy nature.
Anyway, as you can see, this woman is about 1,100 whatever-pixels-translate-into units tall. From the top of her head to her waist is about 32.5% of her height; from her waist to her heels is about 67.5% of her height. Put another way, her waist is about a third of the way down her body.
The way the adult human body is typically depicted in art, it's about 8 head-heights high (in reality, it's more like 7 to 7.5 head-heights high). Even these idealised bodies put the waist 3 head-heights down, at 37.5% of the height (it should be around 40% or more down).
Why do companies do photo-manipulation like this when it makes people look like they have spider legs?
