About this calculator
Shoe sizes use different systems in Europe, the UK, the US, Brazil and Mexico, and men’s and women’s US sizes differ too. This converter turns one size into all the others and estimates the matching foot length.
Choose the system you know, type the size and read the equivalents. You can also start from your foot length in centimetres.
When to use it
- Buying shoes online from another country.
- Converting a child’s size.
- Checking a US or UK size chart.
- Finding your size from a foot measurement.
How to read the result
EU size ≈ (foot length in cm + 1.5) × 1.5. With this tool’s formulas, a EU 42 is about a UK 8.5, a US men’s 9.5 and a US women’s 11.
Conversions are approximate: brands and shoe shapes vary, so check the brand’s chart and try shoes on when you can.
Mistakes to avoid
- Using men’s US sizes for women’s shoes.
- Measuring the foot sitting instead of standing.
- Ignoring width.
