Shoe sizing systems differ between the US, UK, EU, and Asian countries. Learn how to measure your foot and convert to any sizing standard.
Guide étape par étape
Measure your foot length
Stand on a piece of paper and trace your foot. Measure the longest distance from heel to longest toe in centimeters. Use the larger foot if your feet differ in size.
Understand the systems
EU sizes are based on foot length in "Paris points" (1 point = 2/3 cm). US and UK sizes use different scales—US women's is typically 1.5 larger than UK, and US men's is 0.5 larger than UK.
Use our shoe size chart
Open the Shoe Size Chart tool, enter your foot length in cm (or your known size in one system), and get the equivalent in US, UK, EU, JP, KR, and CN sizes.
Account for shoe type
Running shoes often fit differently from dress shoes. For athletic shoes, some people go half a size up. Always check reviews or brand notes on sizing.
When shopping online
Use your foot length in cm as the most reliable reference—size labels differ between brands, but your foot measurement doesn't change.

Questions fréquentes
Q: What if my foot is between sizes?
A: Go up half a size. A slightly loose shoe is more comfortable than a tight one, and thicker socks can compensate.
Q: How often does foot size change in adults?
A: Adult foot size can gradually increase with age, weight gain, or pregnancy. Re-measure if you haven't in a few years.
Q: Why do JP shoe sizes seem different?
A: Japanese shoe sizes equal the foot length in cm (e.g., JP 26 = 26 cm). This makes them the most intuitive to use if you know your foot length.
