The proportional scale of a human figure changes slightly depending on the effect the artist desires. The general rule of thumb for an average scale human would be 7 heads tall and 2 heads wide.
Have any artists worked up rough anatomical scales/ratios for the physical proportions of the non-human races in the CRB?
I recall there were some sketches that appeared in the old 3/3.5 books, but it looks like Paizo might have changed some of the race's scale ratios for their artwork.
