US to UK Shoe Size Conversion Chart

Q: Are EU and US shoe sizes the same?

No. The EU sizing system and US shoe sizing scale use different scales. International shoe size conversion is most reliable when you anchor to foot length in cm.

US and UK shoe sizes use different scales: a US 9 is not the same as a UK 9. US sizes run about one size larger than UK for the same foot length, so converting correctly matters when buying from British brands or shopping in the UK. Our conversion logic uses a single centimeter (foot length) baseline: each size is mapped to a foot length in cm, and that cm value is then matched to the closest size in the target system. That way EU half-sizes, UK whole and half sizes, and US steps are all consistent. The table below is generated from the same dataset that powers the calculator. Each row links to a dedicated conversion page with converter and equivalents.
