US to Japan (JP) 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 Japanese (JP) shoe sizes use different systems. Japanese sizes are based on foot length in centimeters, so the numbers look different from US (e.g. US 9 men's ≈ JP 28). Converting correctly helps when buying from Japanese brands or Uniqlo, ASICS, and other JP-sized shoes. 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 comes from the same dataset that powers the calculator. Each row links to a dedicated conversion page.
