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.
As a note, I don't want to know that this varies depending on certain circumstances, just a good average number that will let me generate people who aren't grossly out-of-proportion
