A shoe size conversion chart converts US sizes to UK, EU and cm: women’s EU = US + 31, men’s EU = US + 33, and women’s US = men’s US + 1.5. For example, a women’s US 8 = EU 38-39 = UK 6 = 24.1 cm, and a men’s US 9 = EU 42 = UK 8.5 = 26 cm.
This guide gives you clear US, UK and EU size charts for men, women and kids. It also shows how to measure your foot and avoid wrong sizes when you shop online.

How To Measure Your Shoe Size

Measure your foot at home with paper, a pen and a ruler. A Brannock device, the metal tool used in many shoe stores, also checks width.
- Measure at the end of the day, when feet are largest.
- Wear the socks you plan to wear with the shoes.
- Stand on paper with your heel against a wall.
- Mark the tip of your longest toe and measure the distance.
- Measure both feet and use the larger one.
Why Shoe Sizes Differ By Country
The US and UK use inch-based scales, but they start from different points. The EU uses Paris points, which is why numbers look so different.
Japan and many sports brands use centimeters (CM/JP). Australia can match either US or UK, depending on the brand.
Even in the same country, a last (the foot-shaped mold) changes fit. Toe box shape and width also change how a size feels.
