Does anybody know the average size of a man foot
This is a question that will have many answers. This is due simply to the huge variety within the species, and the differences between bloodlines, nutrition, nationality, among others.
This article pointed out a fascinating tidbit though, in the UK and US our feet are getting bigger. How much is due to genetic changes, to nutritional changes, to weight changes, and such is just beginning to be studied. Though governments have kept track of general measurements (if nothing else for military gear) for a very long time.
The short answer, per this article, is for the UK size 10 and stateside that’d be an 11.
