Quick answer
Shoe size conversion charts (US, UK, EU, CM, Japan & India)
Find your size in one system and read across to every other. Sizes are approximate because brands and lasts differ; India follows the UK scale and Japan is measured as foot length in centimetres. As a rule of thumb, women's US sizes run about 1.5 larger than men's for the same foot.

Convert foot length in cm to a shoe size
Measuring foot length in centimetres is the most reliable way to size shoes, because EU, Japanese and Asian systems are based on it directly. Measure heel to longest toe, add about 0.5–1 cm of wiggle room, then match the total to the CM (foot) column: a 26 cm foot is a men's US 8 (EU 41), and a 25 cm foot is a women's US 8 (EU 38.5). Measure both feet at the end of the day and size for the larger one.
Kids' sizes to adult sizes
Children's US and UK sizes run up to 13, then restart at adult 1 — so a kids' US 13 is followed by an adult US 1, not US 14. EU sizing is continuous and does not reset, which makes it a useful cross-check when moving a child into adult shoes. A youth US 5–6 (EU 37–38) overlaps with a women's US 6.5–7.5, so older kids can often wear smaller adult sizes.
What is a Shoe Size Converter?
A shoe size converter helps you translate shoe sizes between different international sizing systems. Since countries use different standards for measuring shoe sizes, this tool is essential for shopping for footwear from international brands or when traveling abroad.
The main sizing systems include US (United States), UK (United Kingdom), EU (European), and CM (centimeters, commonly used in Asian countries like Japan and Korea).
Size System Differences
- US Sizing: Used in the United States and Canada. Men's and women's sizes differ, with women's typically 1.5 sizes larger for the same foot length.
- UK Sizing: Used in the United Kingdom and Ireland. Generally about 0.5 smaller than US sizes for men.
- EU Sizing: Used across Europe. Based on the Paris Point system where each size represents 6.67mm.
- CM Sizing: Based on foot length in centimeters. Common in Japan, Korea, and other Asian countries.
How to Measure Your Foot
- Stand on a piece of paper with your heel against a wall
- Mark the longest point of your foot (usually the big toe)
- Measure the distance from the wall to the mark in centimeters
- Use this measurement to find your size in any system
Tips for Finding the Right Fit
- Measure your feet at the end of the day when they're slightly larger
- If one foot is larger, size for the larger foot
- Consider the type of sock you'll wear with the shoes
- Different brands may fit differently even in the same size
