How to Use the Shoe Size Conversion Chart
Shoe sizes vary significantly between countries and even between brands. When buying shoes online from international retailers, knowing your EU, UK, and US sizes helps avoid returns.
Step 1: Measure your foot
For the most accurate conversion, measure your foot length in cm. Place your heel against a wall and measure to the tip of your longest toe. Compare to the cm column. Always measure both feet — the larger foot is your size.
Understanding the women's to men's difference
US Women's sizes are 1.5 sizes larger than US Men's for the same foot length. A women's 9 fits the same foot as a men's 7.5. Many athletic shoes in "men's" or "unisex" sizing will be available in women's equivalent sizes too.
Width sizing explained
US widths use a letter system: AA/2A (narrowest), A, B (standard women's), C, D (standard men's), E/2E (wide), EEE/4E (extra wide). If your foot is wider than average, look for W or Wide designations. Most shoes are made in "medium" width by default.

Is this shoe size conversion chart free?
Yes, completely free with no signup required.
What is the difference between US Men and US Women shoe sizes?
US Women's sizes run 1.5 sizes larger than US Men's. A US Men's 8 equals a US Women's 9.5. This matters when shopping for unisex shoes — always check whether the listing uses men's or women's sizing.
How do EU shoe sizes work?
European sizes are based on the Paris Point system — each EU size represents 2/3 cm of foot length. EU sizes run continuously for men and women (no separate systems). A US Men's 10 ≈ EU 43-44, while a US Women's 10 ≈ EU 41.
Why do shoe sizes vary between brands?
Shoe sizing is not perfectly standardized. Brands use different lasts (the mold shapes used to make shoes), which can make a size 10 fit differently across Nike, Adidas, and Allen Edmonds. Athletic shoes often fit a half-size large, while dress shoes may fit narrow. When in doubt, try shoes on or check brand-specific fit guides.
How do I measure my foot for shoe size?
Trace your foot on paper, then measure the longest distance from heel to longest toe in centimeters. Use the cm column in our chart to find your size. Measure in the afternoon when feet are slightly larger. Wear the socks you'd normally wear with the shoes.
