What is Shoe Size Converter?
The Shoe Size Converter is a free online tool that translates a shoe size between the US (men, women, kids), UK, EU and CM/Mondopoint sizing systems. Enter a size in any one system and the tool immediately shows the equivalent values in all the others, plus the foot length in centimetres and millimetres (Mondopoint). Half sizes are supported, and you can copy the full set of equivalents to the clipboard in a single click.

Frequently Asked Questions
Which shoe sizing systems does the converter support?
It supports US men, US women and US kids numbers, UK numbers, EU numbers, and CM/Mondopoint (foot length in millimetres, ISO 9407). Every output is derived from the same foot length, so the systems stay mutually consistent.
How accurate are the converted sizes?
Conversions use the commonly published linear approximations based on the Brannock foot-length measurement. Real shoes vary between brands and lasts, so treat results as a reference and confirm with the brand size chart before buying.
Why are US men and US women different?
US women's numbering runs roughly one size higher than men's for the same foot length, so a US women's 9 fits a foot that would be a US men's 8. The converter shows both so you can shop across departments.
How do I measure my foot for Mondopoint?
Stand on a piece of paper, trace your foot, and measure the longest point heel-to-toe in millimetres. Enter that value in the CM/Mondopoint system to get your size in every other standard.
