Shoe size converter
Your size in every country — or from your foot length.
Stand on a sheet of paper, mark your heel and the tip of your longest toe, and measure between the marks. Measure both feet in the evening and use the longer.

Example
Example: US men’s 8 to 12 in UK, EU and Japanese sizes
Men’s shoes, starting from the US size. Each size is turned into a foot length first, then into every other system, so each row is what the converter shows for that size.
- US and UK sizes step by a third of an inch, EU sizes by two thirds of a centimetre, which is why the EU numbers jump by 1 or 1.5.
- Women’s shoes, from US 8: UK 5.5, EU 38, Japan 24, for a foot of 24.1 cm.
| US men’s | UK | EU | Japan (cm) | US women’s | Foot length |
|---|---|---|---|---|---|
| 8 | 7 | 40 | 25.5 | 9.5 | 25.4 cm · 10.00 in |
| 9 | 8 | 41.5 | 26 | 10.5 | 26.2 cm · 10.33 in |
| 10 | 9 | 42.5 | 27 | 11.5 | 27.1 cm · 10.67 in |
| 11 | 10 | 44 | 28 | 12.5 | 27.9 cm · 11.00 in |
| 12 | 11 | 45 | 29 | 13.5 | 28.8 cm · 11.33 in |
A men’s US 10 is EU 42.5 and UK 9. Sizes vary by brand, so check the brand’s own chart, especially between half sizes.
How it works
- Choose women’s, men’s or kids’ shoes, then the size system you know and your size.
- Or measure your foot: stand on paper, mark heel and longest toe, and type the length in cm.
- Read the equivalent in every system; your country’s row is highlighted.
Frequently asked questions
- How do US, UK and EU shoe sizes compare?
- A women’s EU 38 is about UK 5½ and US 8, for a foot of 24 cm (JP 24, KR 240). A men’s EU 42 is about UK 8½ and US 9½. US women’s sizes run 1½ above men’s: a men’s US 8 is a women’s 9½.
- How are the sizes worked out?
- From the foot length, using the standard formulas: EU sizes step by 2/3 cm (Paris points), UK and US by 1/3 inch, Japan and Mexico by 0.5 cm, Korea in millimetres. Brazil is about EU − 2.
- Why do my shoes differ between brands?
- Each brand has its own lasts and rounds sizes its own way, so treat the result as a starting point and check the brand’s chart — especially between half sizes.
- What about children’s shoes?
- Kids’ sizes go by foot length too: EU 20 is about 12 cm (UK 4, US 5C); EU 31 is UK 13, US 1Y. Leave about 1 cm of room for growth.
- What size am I with a 27 cm foot?
- Type 27 as your foot length with men’s shoes: US 10, UK 9, EU 42.5, Japan 27. For women’s shoes a 24.5 cm foot gives US 8.5, UK 6 and EU 39.
- What is a men’s US 10 in EU sizes?
- EU 42.5, with UK 9 and Japan 27, for a foot of about 27.1 cm. A brand without half sizes may list it as 42 or 43, so its own chart decides.
- Is anything saved?
- No. It is worked out in your browser.
