Shoe Size Converter

Shoe sizing is a tangle of competing national systems: a men's 9 in the United States is a 42 in Europe, an 8.5 in the UK and around 27 cm in Japan. When you buy from a foreign retailer, that mismatch is exactly where orders go wrong. These converters translate between US, EU, UK, Japanese, Korean, centimetre and inch sizing for men, women and children.

Every conversion is anchored to foot length in centimetres — the one measurement all systems share — so you avoid the rounding errors that come from mapping one country's numbers straight onto another's. Choose a conversion below; each page gives you an instant calculator plus a full, printable reference chart.
