Shoe size converter: men’s, women’s, EU and UK sizes
Women’s US sizes run one size above men’s for the same foot: a men’s 8 is a women’s 9, both for a foot about 10 inches (25.4 cm) long. The converter below goes between US, European, UK and Brazilian sizes from a size you know or from your foot length.
Sizing can differ by up to one size between brands. Measure both feet in the afternoon, use the longer one, and check the brand's own chart in centimeters or inches.
How to measure your foot
- Stand barefoot on a sheet of paper against a wall, heel touching the wall.
- Mark the tip of your longest toe and measure from the wall to the mark.
- Measure both feet, ideally in the afternoon when they are slightly larger, and use the longer one.
How the conversion works
- US men’s: three times your foot length in inches, minus 22. A 10-inch foot is a men’s 8.
- US women’s: one size above men’s on the standard scale.
- UK: one size below US men’s.
- European: 1.5 times your foot length in centimeters, plus 2.
- Brazilian: two below the European size.
Why your size changes between brands
Every brand builds on its own last, and athletic brands often use their own scale: their women’s sizes tend to run a size and a half above men’s, and their European sizes often label about one size higher than a foot-length calculation would. That is why the tool shows the standard conversion plus a note for athletic shoes. When in doubt, check the brand’s own chart in inches or centimeters and leave about a thumb’s width of room at the toe.
