About Shoe Sizes
Translate shoe sizes between US men’s, US women’s, UK, EU, and centimeter foot length.
Shoe systems all describe the same foot. This converter pivots through Mondopoint foot length in centimeters (US Men’s 6 ≈ 24.0 cm, about 0.85 cm per full size), then derives every other system, rounding to the nearest half size.
Brands vary by up to half a size through lasts and padding, so treat conversions as the starting point and check brand charts for expensive pairs. Everything runs in your browser.
Where it is used

Frequently Asked Questions
- Why do conversions differ between brands?
- Lasts (foot forms) differ in width and toe shape, and brands round differently. The math here matches standard charts within half a size.
- Is US Women’s really men’s plus 1.5?
- Yes, that is the industry standard offset (e.g. W7.5 = M6). Widths differ (B vs D), which numbers alone cannot capture.
- What is Mondopoint?
- The ISO system naming sizes directly in foot-length millimeters/centimeters (e.g. 270 = 27.0 cm). It is the only system without conversion ambiguity.
