Clothing Size Converter: Korean, US, EU, UK, Japan
Clothing sizes are a mess across countries — Korean 90 is roughly US Small, US Medium is EU 50, and Japanese sizing runs smaller than Western. This converter handles the most common systems for shirts, pants, and outerwear.
There's no global clothing size standard — each region developed its own system based on local body measurements. Even within one system (US 'Medium'), brands vary enormously. Use a converter as a starting point, but always check brand-specific size charts when ordering.

Tips for ordering across regions
- •Always check the brand's specific size chart, not just the generic letter (S/M/L)
- •Measure yourself in cm and compare to the chart — most reliable
- •Asian brands (Korean, Japanese) often run one size smaller than Western
- •European 'fitted' shirts run tighter than US — size up if in doubt
Extended FAQ
Why do my Korean and US sizes feel different even when the chart says they match?
Cut and shape vary even at the same nominal size. Korean and Japanese cuts are typically slimmer through the body and shorter in the sleeves than US equivalents.
