About Shoe Size Conversion
Shoe sizing systems vary significantly around the world. US sizes for men and women differ by about 1.5 sizes (a men's 9 ≈ women's 10.5). European sizes are based on the "Paris Point" — one-third of a centimeter — with men's EU = US + 33 and women's EU = US + 31. UK sizes are consistently 0.5 less than US men's sizes and 2 less than US women's. For other measurement conversions, our Height Calculator converts between centimeters and feet/inches.
The most reliable way to find your shoe size is to measure your foot length in centimeters from heel to the longest toe, then add 1–1.5 cm for comfort. Foot width also matters — many brands offer narrow (B/D), regular (D/E), and wide (EE/4E) widths. Sizes can vary between manufacturers, so always try shoes when possible. For women's sizing in particular, the Bra Size Calculator offers similar multi-system conversions for another common fitting challenge.
