International Shoe Size Converter: the complete guide
The International Shoe Size Conversion & Foot Length Matcher maps footwear sizing across US Men, US Women, UK, European (EU), Japanese (JP/cm), and Mondopoint military sizing scales. Convert between brands and international regions with accurate millimeter foot measurements.
Why International Shoe Sizing Systems Diverge
Shoe sizing historically evolved from distinct shoemaking last traditions. The UK and US systems are based on the Barleycorn unit (1/3 of an inch), whereas the European Paris Point system is based on two-thirds of a centimeter (6.67 mm). Meanwhile, the Japanese and Mondopoint systems measure pure foot length in centimeters and millimeters.
Men's vs. Women's Sizing Offsets
In the United States, women's shoe sizes are approximately 1.5 sizes larger than men's equivalent sizes (a Men's US 9 corresponds roughly to a Women's US 10.5). In the UK and EU systems, size numbering remains unisex, though width proportions (last volume) differ between gender lines.
