Understanding Shoe Size Systems
What is Shoe Size Conversion?
Shoe size conversion is the process of finding the equivalent size in a different sizing system. There is no single global standard — the United States, United Kingdom, European countries, and Japan each use different numbering systems based on different measurement units and historical conventions. Our shoe size converter maps all major systems — US Men, US Women, UK, EU, Japan (JP/cm), and foot length in cm and inches — using standardized size charts aligned with ISO 19407 and major brand specifications.

- 2. Choose your size: Select your exact size from the dropdown. The options update automatically based on your selected system.
- 3. Get all equivalents instantly: Click Convert to see your size in all 7 systems simultaneously, highlighted in the full size chart — all processed locally in your browser.
The Major Shoe Size Systems Explained
- US Men & US Women:The United States uses separate size scales for men and women. US Women's sizes are 1.5 sizes larger than US Men's for the same foot length (e.g., US Men 9 = US Women 10.5). Sizes are based on barleycorn units (⅓ inch per size step).
- UK (British) Sizes:UK sizes use the same barleycorn unit as US sizes but start from a different base. UK sizes are typically 0.5 smaller than US Men's sizes (e.g., US Men 9 = UK 8.5). UK sizes are unisex — men and women use the same scale.
- EU (European) Sizes: European sizes (also called Paris Point or Continental sizes) are based on ⅔ cm increments. EU sizes are unisex and used across most of Europe. A EU 42 corresponds to approximately US Men 9 / US Women 10.5 / UK 8.5.
- Japan (JP / Mondopoint): Japanese shoe sizes are expressed in centimetres of foot length (Mondopoint system), making them the most intuitive system. JP 26 means a 26 cm foot length. This system is also used in some athletic and military footwear internationally.
Key Shoe Size Conversion Facts
- US Women vs. US Men:US Women's sizes are always 1.5 sizes larger than US Men's for the same foot.
- US Men vs. UK:UK sizes are approximately 0.5 smaller than US Men's (US Men 10 ≈ UK 9.5).
- EU vs. US Men:EU sizes are roughly 33 more than US Men's (US Men 9 ≈ EU 42).
- Brand variation:Sizes can vary by up to half a size between brands. Always check the brand's own size chart when possible, and measure your foot length for the most accurate fit.
