Shoe Size Converter

About this calculator

This converter maps a shoe size across the three main sizing systems — EU (Paris point), US and UK — separately for men's and women's sizing, since the same numeric size means a different actual foot length depending on the system and gender convention used. EU sizes are based on foot length in centimeters times 1.5, while US and UK sizes follow older, less standardized scales that also differ by about a size and a half between men's and women's charts for the same foot.

It's used mainly when buying shoes from a foreign retailer or a foreign brand's website, where the listed size isn't in the system you're used to, and when comparing sizes across brands that print different scales on the box. Because actual fit still varies by manufacturer and shoe last, the conversion is a reliable starting point rather than a guarantee — the description makes a point of calling it approximate for that reason.
