International Shoe Sizing in 2026
Despite globalization, shoe sizing remains stubbornly regional. The US, UK, EU, and Asian markets all use different sizing systems, making international shopping confusing. Our converter uses the most current 2026 conversion standards to help you find the perfect fit anywhere in the world.
Understanding Regional Sizing Systems
US Sizing
Based on the Brannock Device (1920s). Men's and women's scales differ by approximately 1.5 sizes. Common range: Men 7-13, Women 5-11.
UK Sizing
Runs smaller than US sizing. Based on barleycorn units (1/3 inch increments). Historically consistent but less common globally.
EU Sizing (Paris Points)
Measured in Paris Points (2/3 cm). Most scientific and consistent. Common range: Men 40-46, Women 36-42.
CM (Centimeters)
The most universal and accurate method. Measures actual foot length. Popular in Asia and increasingly used globally for precision.

Frequently Asked Questions
- How do I convert US shoe size to EU?
- For men's shoes, add approximately 33 to the US size (e.g., US 10 = EU 43). For women's, add 31 (e.g., US 8 = EU 39). Kids' sizes vary more - use our converter for accuracy.
- Are UK and US shoe sizes the same?
- No. UK sizes run about half to one size smaller than US sizes. For example, a US men's 10 is roughly a UK 9.5. Always check specific conversion charts when buying internationally.
- What does CM mean in shoe sizing?
- CM (centimeters) measures the length of your foot. It's the most universal and accurate sizing method. Measure from heel to longest toe and use that length to find your size in any regional system.
- Why do shoe sizes vary between brands?
- There's no global standard, and brands use different 'lasts' (foot molds). A size 9 Nike may fit differently than a size 9 Adidas. Always measure in CM and check brand-specific size charts for online purchases.
- How should I measure my foot for accurate shoe sizing?
- Stand on paper, mark your heel and longest toe, measure the distance in CM. Do this in the evening when feet are slightly swollen. Measure both feet and use the larger measurement.
- What's the difference between kids', youth, and adult sizes?
- Kids' sizes typically go from infant through size 13. Youth sizes (GS - Grade School) bridge the gap between kids and adults, usually ranging from 3.5-7. Adult sizes start at different points for men and women.
