I have been working on a drawing that will be made into a pose able doll in the near future. This has lead me to research various opinions about human proportions. I have a very old anatomy book by Dr.Paul Rich that goes into great detail about different ways of measuring the human body.
However, I wanted to share a link that I also found very useful:

It covers male vs. female, as well using different heights based on the head length
