Shoe sizing is a mess: Europe, the UK and the US all use different scales, and men's and women's sizes are different. Buying online makes it worse.
Quick answer
Choose men or women, pick the system you know and enter your size. You get the other systems and the foot length in centimetres.
Rough guide (men)
| EU | UK | US | Foot length |
|---|---|---|---|
| 40 | 6.5 | 7 | 25.0 cm |
| 41 | 7.5 | 8 | 25.7 cm |
| 42 | 8 | 9 | 26.5 cm |
| 43 | 9 | 10 | 27.3 cm |
| 44 | 10 | 11 | 28.0 cm |
Women's US sizes are about 1.5 larger than men's UK sizes. For example, a US women's 8 is about a UK 6 and an EU 39.
Steps
- Choose gender.
- Pick EU, UK or US.
- Enter the size and read the others.
Measure your foot
- Stand on paper and trace your foot.
- Measure from the heel to the longest toe in centimetres.
- Add 0.5 to 1 cm for comfort.
- Compare with the brand's chart.
Tips
- Brands differ by half a size or more; check their chart.

- Check width as well as length.
- Look at reviews for "runs small" or "runs large".
- For children, leave about 1 cm of growing room.
