Clothing Size Converter
Clothing size systems vary significantly around the world, making it confusing to shop internationally or convert a size label from one country to another. This converter maps alpha sizes (XS, S, M, L, XL, XXL) to numeric sizes used in the US, EU, and UK for both men's and women's tops, using standardized lookup tables based on widely adopted industry measurements.
Whether you are buying clothes online from a European brand, comparing a US size to a UK size, or simply trying to understand what 'EU 40' means in alpha sizing, this tool provides instant, side-by-side conversions across all four systems. Separate tables for men and women ensure accurate results, since sizing conventions differ significantly between genders.
How it works
Clothing size conversion uses fixed lookup tables rather than a mathematical formula. Each alpha size (XS–XXL) maps to a specific numeric value per region: for women's tops, S corresponds to US 4, EU 36, UK 8; for men's tops, S corresponds to US 36, EU 46, UK 36. Values are based on industry-standard chest and body measurements.
Use cases
- Shopping from international online stores (EU, US, or UK brands)
- Sending clothing gifts to friends or family abroad
- Understanding size labels on imported or vintage garments
- Comparing sizing between different regional fashion brands
- Converting a known alpha size to numeric for a tailoring reference
