The size depends on your map scale. The average adult human height is anywhere from 66 to 70 inches tall. If your map scale is 16 quants to 1 foot, then your player character would be about 88 to 93 quants tall for the same average height. If it was 8 quants to 1 foot (as in my case) it would be from 44 to 47 quants tall instead. If using 32 quants per inch, it'd be 176 to 187 quants.
