Shoe Size Converter
Convert foot length to EU, US men's, US women's and UK sizes.
The Shoe Size Converter maps foot length in centimeters to the main sizing systems: EU, US men's, US women's, UK and Mondopoint. Type your measured foot length and see your size across all five at once.
Shoe sizing is a mess of offset systems — EU sizes run a continuous numeric scale, US men's and women's differ by roughly 1.5 sizes, and UK trails US men's by one. Online shopping across borders fails daily on exactly this confusion, which is why measuring your foot in cm and converting is the reliable path.
Conversions use the standard approximation formulas from foot length (EU ≈ (cm + 1.5) × 1.5). Brands vary, so treat the result as a starting point and check each brand's chart — and measure both feet, ordering to the larger. Runs locally.

Approximate adult conversions: EU ≈ (cm + 1.5) × 1.5; US men ≈ EU − 33; US women ≈ EU − 31; UK ≈ US men − 1. Sizes vary by brand and width — measure both feet (use the larger) and try before buying.

- Enter that length.

Frequently asked questions
How do I measure my foot size?
Stand on paper with your heel against a wall, mark the longest toe, and measure heel-to-mark in cm. Measure both feet — most people have one larger — and size to the bigger one.
What is EU size 42 in US sizes?
EU 42 corresponds to about US 9 for men and US 10–10.5 for women (depending on the brand). The converter gives exact equivalents from your measured cm.
Why do brands disagree on sizes?
Sizing is unregulated: lasts (foot molds) vary by brand and model, and 'vanity sizing' drifts over time. Cm measurements and insole length are the only consistent language between brands.
