About this tool
This page opens the shoe size converter with the kids' chart preselected: enter a child's size in US, UK or EU — or better, a measured foot length in centimetres — and get the matching size across every system in one row.
Children's sizing is the trickiest corner of the shoe world: US kids' sizes run through child sizes 10C–13.5C and then restart as youth sizes 1Y–6Y, UK numbers sit one size lower, and EU continues its single Paris-point scale from 27 to 38. Because kids' feet grow roughly half a size every few months, measuring the foot in cm and converting from that is far more reliable than converting a possibly outgrown labelled size — and, as with adult shoes, brands still vary by up to half a size, which the tool states with every result.
The complete converter is available on this page, just preset to kids' mode — you can switch to men's or women's charts at any moment. All tables are bundled statically and every conversion is computed locally in your browser, with nothing uploaded anywhere.
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.
