What is the average Leg-to-Foot Length/Width Ratio?

Question

I'm making a program that estimates a probable size (widest width and longest length) for a human's foot given the length and width of the leg to which it is attached. However, try as I might, **I can't seem to find the average foot-to-leg size ratio. Does anyone know this?** It would be even better if you have different ratios for males and females.

Answer 1

A study conducted showed that foot to length ratio was 1:3 for males and females, while the width was 2:3 for males and 1:2 for females.
