Understanding EU to US shoe size conversion is important when buying shoes from international brands. Since sizing systems differ across regions, a correct conversion helps you avoid fit issues and ensures better comfort.
In general, European (EU) shoe sizes are based on the Paris point system, while US sizes follow a different numerical scale. This means a direct one-to-one match does not exist, so using a conversion chart is the most reliable method.

Understanding Shoe Size Differences
Unlike the US shoe size system, which includes half sizes and separates men’s and women’s sizes, EU shoe sizes follow a standardized, unisex system. This difference can make conversions tricky, as EU sizes are based on foot length in centimeters, while US sizes are not.
Additionally, size charts vary slightly between brands, so a size 9 in one brand may fit differently than in another. Balancing these differences is crucial for finding the right fit, especially when shopping online. Understanding these nuances helps ensure comfort and reduces the risk of returns.
EU to US Men’s Shoe Size Conversion
EU men’s shoe sizes are typically 31–50+, while US men’s sizes usually range from 6–16+. Below is a general conversion guide:
- EU 39 → US 6.5
- EU 40 → US 7–7.5
- EU 41 → US 8
- EU 42 → US 8.5–9
- EU 43 → US 9.5–10
- EU 44 → US 10–10.5
- EU 45 → US 11
👉 Note: Brand differences may slightly affect final fit.
EU to US Women’s Shoe Size Conversion
Women’s sizing varies slightly more between brands, but here is a standard reference:
- EU 35 → US 5
- EU 36 → US 6
- EU 37 → US 6.5–7
- EU 38 → US 7.5–8
- EU 39 → US 8.5
- EU 40 → US 9–9.5
- EU 41 → US 10
How EU Shoe Sizes Work
EU shoe sizes are based on a metric system where each size equals approximately 2/3 of a centimeter in foot length. This makes EU sizing more consistent compared to US sizing, but still not identical across brands.
Key Differences Between EU and US Shoe Sizes
- EU sizing is unisex and more standardized
- US sizing separates men’s and women’s scales
- Fit can vary depending on shoe type (sneakers, boots, dress shoes)
- Some brands run smaller or larger than standard conversion charts
Tips for Choosing the Right Size
- Always measure your foot length in centimeters before buying
- Check brand-specific size charts when available
- If between two sizes, consider sizing up for comfort
- Read customer reviews for real fit feedback
