When to use it

Use this converter when buying shoes from another country or an international online shop. It converts between US, UK and EU sizes and foot length in centimeters, with separate charts for women, men and kids. It is also helpful when buying shoes as a gift and you only know someone’s size in one system.

How to use it

  1. Under Shoes for, choose Women, Men or Kids.
  2. Under I know my size in, choose US, UK, EU or Foot length (cm).
  3. Pick your size from the Size list.
  4. Read Your size in other systems, which shows the US, UK and EU size and the foot length.
  5. Check the full chart below. Your size is highlighted.

Worked example

You wear a women’s US 8.5 and want to order from a European shop. Choose Women and US, then pick US 8.5. The result shows UK 6, EU 39 and a foot length of 25.5 cm.

For a man who wears a US 10, choose Men and pick US 10. That is UK 9.5 and EU 44, for a foot about 28 cm long.

If you are not sure of your size at all, measure your foot, choose Foot length (cm), and pick the length closest to yours, rounding up.

Buying for children

Children’s feet grow fast, often by a size every few months when they are small. Measure before every purchase and leave about 1 cm of space beyond the longest toe. Choose Kids to see toddler (C) and youth (Y) sizes alongside UK and EU sizes.

Tips

  • Measure in the evening. Feet swell during the day, so evening measurements match how shoes feel when you wear them.
  • Allow for socks. Hiking and winter boots often need half a size more for thick socks.
  • Read reviews. Buyers often say if a shoe runs small or large.
  • Check the return policy. International returns can be slow and costly.

Common mistakes

  • Using the women’s chart for men’s shoes. US women’s and men’s sizes differ by about one and a half sizes.
  • Rounding down between sizes. A shoe that is too short causes more problems than one that is slightly long.
  • Forgetting that EU sizes can vary. Some brands use whole EU sizes only, so you may need to choose between two.

Foot length is the best guide when sizes do not match exactly. If a brand gives a chart in centimeters, compare it with your own measurement.

Frequently asked questions

Are shoe sizes the same for every brand?

No. Sizing varies between brands and even between styles from the same brand. Use the converter as a starting point, then check the brand's own chart, especially for running shoes and boots.

How do I measure my foot length?

Stand on a sheet of paper with your heel against a wall. Mark the tip of your longest toe, then measure from the wall to the mark in centimeters. Measure both feet in the evening, when feet are slightly larger, and use the longer one.

Why are women's and men's US sizes different?

The US uses separate scales. A women's US size is usually about 1.5 sizes larger than the men's size for the same foot. UK and EU sizes are generally the same for men and women.

What do the C and Y mean in kids' sizes?

C stands for child or toddler sizes, which count up to 13C. After that, sizing starts again at 1Y for youth, also called big kids.

What should I do if I am between sizes?

Choose the larger size, especially for walking and running shoes. Feet swell during exercise and over the day, and a little extra room is more comfortable than a tight fit.
