Pinning down Proportions

Jeff LaMarche has two great articles on proportions that are must reads if you are sculpting or drawing the human figure.

Canons of Proportion and the Ideal, Part 1 covers the systems of ideal proportions laid out through history. The Egyptians, Greek, Vitruvius, etc.

Canons of Proportions II - Faith-Based Canons? takes data from real people (in this case military personel) to determine what the real average human proportions and standard range most people fall into.
