- • Korean sizes are often in mm for shoes and use a numeric system for clothing
- • Always check the specific brand's size chart when shopping online
How Clothing Sizes Differ Around the World
There is no universal clothing size standard. Each country uses its own system, making international shopping confusing. US sizes use letter codes (S, M, L) or numeric values, UK sizes run about 4 numbers higher than US for women, EU sizes use a continental numbering system, and Asian sizes (Japan, China, Korea) generally run 1–2 sizes smaller than Western equivalents.
Shoe sizes are even more varied — Japan uses centimeters, Korea uses millimeters, and the US, UK, and EU each have their own scale. Our converter covers all the major systems so you can shop with confidence anywhere in the world.

Frequently Asked Questions
Why are Asian sizes smaller than US/UK/EU?
Asian sizing systems are based on body measurements typical of their populations. Since average body dimensions differ across regions, a "Medium" in China or Japan generally corresponds to a "Small" in the US or UK. Always size up 1-2 sizes when buying Asian-sized clothing.
Are EU clothing sizes the same across all European countries?
Generally yes — the EU sizing system is standardized across most European countries. However, some brands in Italy, France, or Spain may have slight variations, so it's always good to check the brand's specific size chart.
How do I convert US women's sizes to UK?
For women's clothing, add 4 to your US size to get the approximate UK size. For example, a US 8 is roughly a UK 12. For shoes, subtract about 2 from your US size to get the UK equivalent.
What's the most reliable way to find my size in another country?
The most reliable method is to use body measurements (bust, waist, hip circumference for clothing; foot length for shoes) rather than converting between size labels. Our charts include reference measurements where available.
Do Korean clothing sizes work differently?
Korean clothing uses a numeric system (44, 55, 66, 77, etc.) that corresponds roughly to body measurements. Korean shoe sizes are measured in millimeters (e.g., 250mm = US men's 7). These sizes are used widely in K-fashion and Korean e-commerce.
Are children's sizes universal?
No — children's sizing varies widely. US sizes use age or numeric values (2T, 4T, 6), UK uses age ranges, EU uses height in centimeters, and Asian sizes often correspond to the child's height. Our chart maps all these systems together.
