Shoe Size Converter
Convert shoe sizes between US, UK, EU, Indian, and CM. Find your international shoe size equivalents.
About this calculator
Shoe sizes differ between countries and between brands. Enter a size in US Men's, US Women's, UK or Indian, EU or foot length in centimetres, and this converter gives the equivalents in the other systems, plus an estimated foot length.
It uses the standard sizing logic, a 1 cm margin on the foot and the Paris point (2/3 cm) for EU sizes and the barleycorn (1/3 inch) for UK sizes. Indian sizes follow the UK scale. Treat the result as a starting point and always check the brand's own chart.
How to use it
- Type the Size Value.
- Choose the From Size System.
- Press Convert.
Sizing logic
Last length = foot length + about 1 cm. EU = last length (cm) × 1.5. UK = last length (inches) × 3 − 25. US Men = UK + 1 and US Women = UK + 2.5. Results round to the nearest half size.
Worked example
UK / India size 8
| US Men | 9 |
| US Women | 10.5 |
| EU | 42 |
| Foot length | about 26.9 cm |
