Shoe size converter
What is a Shoe Size Converter?
Shoe size systems differ by country, and even between men's and women's sizes in the same country. A US men's 9 is not a US women's 9, and EU sizes use a completely different scale. This converter translates between the major systems and foot length, which is the most reliable reference when buying shoes online.
How to use it
- Choose the system you know, such as US men's, US women's, UK or EU.
- Enter your size.
- Read the equivalent sizes and the approximate foot length.
Approximate equivalents
- US men's 8 = UK 7.5 = EU 41 = about 26 cm
- US men's 9 = UK 8.5 = EU 42.5 = about 27 cm
- US men's 10 = UK 9.5 = EU 44 = about 28 cm
- US women's 7 = UK 4.5 to 5 = EU 37.5 to 38 = about 24 cm
- US women's 8 = UK 5.5 to 6 = EU 38.5 to 39 = about 25 cm
US women's sizes are typically 1.5 sizes larger than US men's for the same foot.
How the systems work
- UK and US sizes step by a barleycorn, one third of an inch (about 8.47 mm).
- EU (Paris point) sizes step by two thirds of a centimetre (6.67 mm) and are based on the length of the shoe's last, not the foot.
- Mondopoint (used for ski boots and in Japan) is simply foot length in millimetres.
Measuring your foot
- Stand on a sheet of paper in the evening, when feet are largest.
- Mark the tip of the longest toe and the back of the heel.
- Measure the distance and use the larger foot.
Brands vary, so always check the brand's own size chart. Running shoes often need half a size larger.
