How to Convert Shoe Sizes
Shoe sizes use different numbering systems around the world. This converter handles US, EU, UK, and centimeter (foot length) measurements.
The sizing systems
- US: Starts at ~1 for adults. Men's and women's sizes differ by 1.5 (a men's 8 ≈ women's 9.5).
- EU: Uses a continuous numbering system (typically 35–48 for adults).
- UK: Similar to US but offset by 1 (men) or 1.5 (women).
- cm: Actual foot length in centimeters — the most accurate method.
Step-by-step
- Select men's or women's sizing.
- Choose which system you are converting from.
- Enter the size you know.
- The calculator shows all four equivalents.
Worked example
Men's US size 10: EU ≈ 43.5, UK ≈ 9, foot length ≈ 27.3 cm.
Tip
Sizing varies between brands. Always check the brand's specific size chart when ordering online. The cm (foot length) method is the most reliable for international ordering — measure your foot from heel to longest toe and use that as the reference.
