How Shoe Size Systems Compare Worldwide
Shoe sizing varies significantly across countries and regions. The US system uses a Brannock scale with half-size increments. The UK system is similar but offset by about 0.5 to 1 size for men. The European system uses the Paris point (6.67mm per size) and is unisex, making it simpler in some ways.
Asian shoe sizes (Japan, China, Korea) typically use centimeters directly based on foot length, which is the most intuitive system. Japanese sizes measure the foot in centimeters. Korean sizes are in millimeters (250 = 25.0 cm). Brazilian sizes use their own numbering that roughly parallels European sizes.
For the most accurate fit, measure your foot length in centimeters at the end of the day when your feet are largest. Stand with your full weight on the foot being measured. Remember that sizes can vary between brands and even between shoe styles within the same brand.
