What Is Shoe Size Converter?
A shoe size converter translates between the five major international sizing systems: US, UK, European (EU), Japanese (JP, in centimeters), and Chinese (CN). Shoe sizing is not a simple mathematical formula — it involves different starting points, increments, and measurement methods across regions. The US and UK systems are both based on inches but start at different points. The EU system uses the Paris point (2/3 cm). JP sizes directly indicate foot length in centimeters. This converter uses standard industry lookup tables for accurate conversions across men's, women's, and children's sizing.

Technical Guide
Shoe sizing systems:
• US: Based on the Brannock Device. Men's and women's sizes differ by about 1.5 sizes (women's 8 ≈ men's 6.5). Sizes increase by 1/3 inch (8.47 mm) per half size.
• UK: Similar to US but offset. UK sizes are roughly 0.5-1 size smaller than US men's. Based on the barleycorn (1/3 inch).
• EU (Paris Point): Each size represents 2/3 cm (6.67 mm). No distinction between men's and women's numbering. Common range: 35-48.
• JP: Directly measures foot length in centimeters. The simplest system. Men's range: 24-31 cm.
• CN: Uses the European numbering system.
Note: These are approximate equivalences. Actual fit varies by manufacturer, shoe shape (width, toe box), and whether measuring foot length or last length. Always try shoes on when possible.
