About the Shoe Size Converter
This shoe size converter translates between US, UK, EU and centimetre (foot length) sizing for both men and women. Choose your gender and the region you know, enter your size, and it shows the equivalents across every system, with the matching row highlighted in a reference chart.
Shoe sizing differs by country and by gender, so a single number means different things depending on the scale — which is exactly why ordering shoes from an overseas brand is so error-prone. Lining every system up in one place removes the guesswork.
All conversions run locally in your browser against standard sizing charts, giving instant results for online shopping, travel and gifts.

Frequently Asked Questions
How do I convert US shoe size to EU?
For men, a US 9 is about EU 42; US 10 is EU 43–44; US 11 is EU 44–45. For women, a US 8 is about EU 38.5–39. Because the scales don't step evenly, use the chart in this tool for your exact size rather than a single rule of thumb.
How do I measure my foot length in centimetres?
Stand on a sheet of paper, mark the back of your heel and the tip of your longest toe, and measure the distance in centimetres. Measuring foot length and matching it to the cm column is the most reliable way to find your size across brands.
Are men's and women's shoe sizes the same?
No. For the same foot length, women's US sizes run about 1.5 numbers higher than men's, and the EU and UK scales differ too. That's why this converter asks you to pick a gender first — using the wrong chart can put you a full size off.
Why do sizes vary between brands?
Different manufacturers use slightly different lasts (the moulds shoes are built on), so even within one country a size can fit differently. Treat converted sizes as a strong starting point, check the brand's own size guide, and rely on foot length in cm when unsure.
What's the difference between US and UK shoe sizes?
UK sizes run smaller numbers than US for the same foot: men's US sizes are about 0.5–1 larger than UK, and women's US sizes are roughly 2 larger than UK. The chart here shows the exact mapping so you don't have to remember the offset.
