Find size by foot length

Measure heel to longest toe.
Use the longer foot if your feet differ.

Tip: shoe size conversion is approximate. Foot length in centimeters is usually the most reliable value to compare across brands.

How to measure shoe size

  1. Stand with your full weight on a sheet of paper.
  2. Mark the back of the heel and the longest toe, then measure the distance.
  3. Measure both feet and use the longer measurement when choosing a size.

Fit tips before buying

  • Running shoes and boots often need a little extra room.
  • Wide feet may need a larger size or a wide-width version.
  • Kids’ feet grow quickly, so check foot length often.

Shoe size conversion notes

Shoe sizes are not perfectly standardized. A US men’s 9 and EU 42 are often close, but brand shape, toe box width, socks and shoe type can change the best fit. When possible, compare the centimeter measurement with the brand’s chart.

For athletic shoes, many people prefer about a thumb’s width of extra space. For formal shoes, a closer fit may be normal, but the shoe should not pinch the toes or heel.

Shoe Size Converter FAQ

How do I convert shoe sizes?

Choose a men’s, women’s or kids chart, select the size system you know, and the converter will show the nearest US, UK, EU, centimeter and inch equivalents.

Are shoe size conversions exact?

No. Shoe sizing differs by brand, last shape and region. The converter gives a practical estimate, and foot length in centimeters is usually the best comparison point.

How should I measure my foot length?

Stand on paper, mark the heel and longest toe, then measure the distance. Measure both feet and use the longer foot when choosing a size.

What if I am between shoe sizes?

For running shoes, boots or wide feet, sizing up is often safer. For leather dress shoes, check the brand’s fit notes because the material may stretch slightly.
