About this tool
Convert any shoe size in seconds
Buying shoes from another country — or online from a brand that lists a different system — means decoding US, UK and EU sizes that all use different numbers for the same foot. A shoe size converter removes the guesswork: pick your gender, enter a size you already know in any system, and the matching row lights up in a full chart showing the US, UK, EU, centimetre and inch equivalents together.
The most reliable way to find your size is by foot length. Shoe sizes ultimately map to how long your foot is, so measuring it in centimetres and entering that in the CM field gives the most accurate result across every system. The chart is built around foot length for exactly this reason, and includes inches for convenience. Separate charts for men, women and kids account for the fact that the same foot length is numbered differently across these groups.
Remember that sizing varies between brands because each uses its own last, or foot-shaped mould — Nike tends to run small, Adidas large, and New Balance true to size. Use this tool as a solid starting point, then check the specific brand's size guide and reviews before ordering. Everything runs in your browser with no account and nothing uploaded, so it's quick, free and private whenever you're shopping.

FAQ
Frequently asked questions
How do I convert US shoe size to UK?
For men, a US size is roughly half a size larger than the equivalent UK size — so US 9 is about UK 8.5. For women the gap is bigger, around two sizes (US 8 is roughly UK 6). Rather than rely on a single rule, pick your gender, enter your known size in any system, and this converter highlights the matching row with the US, UK, EU, centimetre and inch equivalents side by side.
What is EU shoe size in US?
European sizes use the Paris point system and run higher numerically — EU 42 is about US 9 for men and roughly US 11 for women. Because men's and women's scales differ, always convert within the correct gender chart. Enter your EU size above and the tool shows the US, UK, CM and inch equivalents instantly.
How do I measure my foot size at home?
Stand on a sheet of paper with your heel against a wall, trace around your foot, and measure the distance from the wall to the tip of your longest toe in centimetres. Measure both feet in the evening (feet swell during the day) and use the larger one. Add about 0.5–1 cm for comfort. Then enter that length in the CM field to find your size in every system.
Are shoe sizes the same across brands?
No — sizing varies noticeably between brands and even between models from the same brand, because each uses its own 'last' (the foot-shaped mould). Nike tends to run about half a size small, Adidas about half a size large, and New Balance close to true to size. Use this converter as a starting point and always check a brand's own size guide and customer reviews.
Do men's and women's shoe sizes differ?
Yes. For the same foot length, men's and women's US and UK numbers differ — a women's US size is typically about 1.5 sizes higher than the men's number for the same length. EU sizing is closer to unisex but still listed separately here. That's why this tool has separate charts for men, women and kids; pick the right one before converting.
