I thought I'd throw this up for giggles.  Earlier today I ran across a website that listed basic body proportions for men and women, based on studies the US Army organized in the 1970s.  Thousands of college students had various measurements taken to get various proportions related to their height, the Army's reason being so they could figure out what uniform dimensions they had to order based on what would fit 99.7% of military-age people for a given height.

So, I had to try it.

The way I did this was arrange the characters in a row, aith the Aiko 3 realistic morph turned on.  Since I knew already that their heads were well out of proportion, in order to set a base height I used the shoulder.  For a 5'6" (66") woman, the shoulder height will be 54" off the ground.  I adjusted the shoulder/collars to get a more realistic posture, figuring 10 degrees down looked good on all of them.  Then I simply scaled the whole body so the shoulders were at the proper height.  Then, I scaled the heads to get them up to close to the 5'6" mark.  Numbers are on the image, obviously.

All measurements are Poser 7 using inches.

What was really interesting was that when I measured the other baselines the study reported for the main body (waist, crotch, and knees), not only did the figures match up pretty closely with each other, they matched what the real world measurements would be almost spot on.  So vertical scaling of the torso and legs wasn't required at all.  Their arms are obviously different

Horizontal scaling, however...

Stephanie 3 looks almost normally proportioned.  Obviously with large traps and long neck giving the sloped shoulders and more toward the working-out type of body, but not bad.  Victoria 3 is pretty close, could use some more width in the shoulders.  Aiko 3 needs a lot more width in the body, and the neck is very thin in comparison, but given that it's based on an anime character, one doesn't expect much realism.  Victoria 4, on the other hand, who is supposed to look real, looks too young in the given proportions.

Basically, it's all in the heads.  The body scaling, once you adjust for height, is pretty good.  The heads are all out to lunch (he says knowing that everyone knows it already).
