About this tool
This page opens the shoe size converter with the direction already pinned: US as the source system and EU as the target. Pick men's, women's or kids', type your US size, and the EU size appears together with the full chart row — UK, JP and foot length in centimetres included.
US and EU scales have no neat formula between them: US sizes step in barleycorns (a third of an inch) and differ between men and women, while EU sizes step in Paris points (two thirds of a centimetre). A men's US 9 lands on EU 42, a women's US 9 on EU 39.5 — and because every brand cuts its own last, the real fit can still drift by about half a size, which the tool honestly reminds you of with every result.
You are looking at the complete converter, just preconfigured — you can switch categories, reverse the direction or start from a measured foot length in cm at any time. The charts are bundled with the page and every lookup runs locally in your browser: nothing is uploaded and no account is needed.
Example. Men's US 9 maps to UK 8.5, EU 42, a 26 cm mondopoint length, and JP 27.
Limit. Men, women, and kids use separate tables, and the chart does not absorb brand-to-brand last differences of about half a size.
