Why Shoe Sizes are So Confusing
There is no global standard for shoe sizes. Each region uses a different starting point and a different increment.
The Main Systems
- US / Canada: Based on "barleycorns" (1/3 inch). Men's and women's sizes are different.
- UK: Also based on barleycorns, but starts at a different zero point.
- Europe (EU): Uses "Paris Points" (2/3 cm). Sizes are unisex.
- Japan (JP): The most logical—it's just the length of your foot in centimeters.
Men's Conversion Table (Approx)
| US | UK | EU | JP (cm) |
|---|---|---|---|
| 8 | 7.5 | 41 | 26 |
| 9 | 8.5 | 42 | 27 |
| 10 | 9.5 | 43 | 28 |
| 11 | 10.5 | 44 | 29 |
Key Takeaways
- Japanese sizes are the most accurate (cm)
- Always check the brand's specific size chart
- EU sizes don't distinguish between gender
