How shoe size systems differ
The main systems measure different things. US and UK sizes count in barleycorns (one third of an inch) from different starting points, so a UK size is usually half to one size smaller than the US men’s size. European (Paris point) sizes count in two-thirds of a centimetre and are based on the length of the shoe’s last, not the foot. Mondopoint, used for ski boots and military footwear, is simply the foot length in millimetres.
| US men | US women | UK | EU | Foot length |
|---|---|---|---|---|
| 7 | 8.5 | 6.5 | 40 | 24.8 cm |
| 8 | 9.5 | 7.5 | 41 | 25.4 cm |
| 9 | 10.5 | 8.5 | 42.5 | 26 cm |
| 10 | 11.5 | 9.5 | 44 | 27 cm |
| 11 | 12.5 | 10.5 | 45 | 27.9 cm |
Men’s vs women’s sizes
In the US, women’s sizes run 1.5 sizes (sometimes 2) above men’s for the same length. UK and EU sizes are usually unisex. When buying unisex sneakers labelled in men’s sizes, subtract 1.5 from your women’s size.
How to measure your foot
Stand on a sheet of paper against a wall, mark the tip of your longest toe and measure from the wall to the mark in centimetres. Measure both feet in the evening, when feet are largest, and use the longer one. Add about 1 to 1.5 cm of room for the shoe; the foot length column in the chart already refers to the foot, not the shoe.
Why sizes vary by brand
There is no single international standard that every brand follows. Sports brands, Italian shoes and boots can differ by half a size or more, and widths vary too. Use the converter as a starting point and check the brand’s own chart before ordering, especially when buying abroad.
