Shoe Size Converter

Measure your longer foot from heel to the longest toe, in centimetres.

cm

Measure standing, in the evening, on a sheet of paper. Use the longer foot and add nothing.

This result is an estimate only. Double-check important figures before relying on them.

How it is calculated

  • EU size ≈ (foot length in cm + 1.5) × 1.5
  • US men ≈ 3 × foot length in inches − 22, US women ≈ men + 1.5
  • UK ≈ US men − 1
  • All rounded to the nearest half size

For other conversions, use the general unit converter.

Worked example

A 26 cm foot (10.24 inches):

  • EU about 41.5
  • US men’s 8.5, US women’s 10, UK 7.5

Why your number may differ

Sizing systems are not standardised across brands, and children’s sizes follow different scales. Treat the result as a starting point.

Frequently asked questions

How do I measure my foot?

Stand with your heel against a wall on a sheet of paper, mark the longest toe and measure from the wall to the mark. Do both feet and use the longer one.

Are these sizes exact?

No. They come from common conversion formulas. Brands, lasts and styles differ by half a size or more. Check the brand's own chart, especially for sports shoes.

Should I add room for my toes?

Yes. Most people want about 1 cm of room beyond the longest toe, which is partly built into shoe sizes.
