UK to US 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.

UK and US shoe sizes use different scales: a UK 8 is not the same as a US 8. US sizes run about one size larger than UK for the same foot length, so converting correctly matters when buying from American brands or shopping in the US. Our conversion uses a single centimeter (foot length) baseline: each size is mapped to a foot length in cm, and that cm value is matched to the closest size in the target system. The table below is generated from the same dataset that powers the calculator. Each row links to a dedicated conversion page with the converter and equivalents.
