Quote - My wife claims that most people are as tall as the distance from finger tip to finger tip when they stand with their arms stretched straight out. If that is true you could place a figure in a square template to check proportion for arm length. I have noticed that for the most part head and trunk size is the same person to person and people are taller or shorter based on the length of their thighs and shins. I have not figured out how arm length fits into it but it does seem to me that most people's arm length is such that when they put their arms down straight their wrist or palm is in line with their groin...

Yep your wife is right. If you've ever studied Leonardo Davinci's drawings ( who studied human cadavers, so he knew a thing or two about proportions of the human body ) the "wing span" ( finger tip to finger tip in a t-pose) of a person is generally identical or very close to to a persons height. Not always because it can vary from person to person but generally it's a good guide. In some art books I have looked at a typical male is 7.5 to 8  heads tall. and the typical female is 7 to 7.5  heads tall. But for some reason it looks strange in 3d.  Personally I think 7 heads for males and 6.5 for females "looks" more accurate. A lot of 3d figures ( female figures in particular ) exaggerate this by making the hips too high and the shoulders too narrow. It has the effect of making the limbs look much longer than they should be. There's an interesting study by ( IIRC ) some german researchers I stumbled across about human proportions and beauty. The ideal female that most people choose was in between barbie like proportions and the classic 50's era hourglass. The article went on to explain that the ideal woman in medieval time was pretty much the opposite of the 21st century ideal. You can compare Botticelli's birth of Venus to todays Playboy bunnies and supermodels to get the idea. I think marketing has alot to do with what is considered beautiful nowadays.

Anyway I think OFD's proportions for Antonia are spot on and it's nice to see a figure moving away from your typical barbie look. The barbie look can be achieved easier if you want that look through morphs and or scaling and IMO is easier achieved if the proportions are correct in the first place.
