Introduction
Shoe sizes vary dramatically between countries and even between brands within the same country. A US size 10 is different from a UK size 10, and European sizing uses a completely different system. Our shoe size converter helps you find the perfect fit across all systems.
How Shoe Sizing Works
Different regions use different sizing standards:
US Sizing: Based on barleycorn units (1/3 inch increments). Men's and women's scales differ. UK Sizing: Similar to US but shifted by 1.5 sizes (UK 9 = US 10.5 for men). EU Sizing: Based on Paris point (2/3 cm per size). Ranges from 32 to 52+. Japanese Sizing: Directly in centimeters (foot length). Mondopoint: International standard based on foot length in millimeters.Key approximate relationships:
US Men's = UK + 1 US Women's = US Men's + 1.5 (varies by brand) EU = (US Men's x 1.27) + 29 (approximate) JP cm = (US Women's + 18.5) / 1.5 (approximate)How to Use the Converter
Our shoe size converter supports all major systems. Select your source system, enter your size, and choose the target.
For example, US Men's 10 = UK 9 = EU 43 = 27.3 cm.
