無料のオンライン靴サイズ変換ツール。US、UK、EU、CM の各サイズ規格間で換算。
Shoe sizes are notoriously inconsistent across countries and brands. A US size 10 is a UK size 9, a European size 43, and approximately 27.5 centimeters. When shopping online from international retailers or buying shoes from different countries, getting the conversion right is essential. Shoe Size Converter handles conversions for men, women, and children across all major sizing systems.
Select the gender (men, women, or kids) — sizing systems differ significantly by gender. Men's sizes are typically larger and use different conversion ratios than women's. Choose your input sizing system: US, UK, EU, or CM (centimeters). Enter your known size and the equivalent sizes in all other systems are displayed instantly.
The converter uses standard conversion tables: US men's sizes are approximately 1 size larger than UK men's sizes. Women's US sizes are approximately 2 sizes larger than UK women's sizes. EU sizes are consistent across genders but use a different numerical scale. CM sizes represent the actual foot length in centimeters.
The complete size chart shows all available sizes for the selected gender category across all four systems. Use this chart to browse across the full size range, compare systems side by side, and find your size in an unfamiliar system. The chart covers the most commonly available sizes for each gender.
