Clothing Size Converter — International Size Guide
Shopping for clothes internationally or online means navigating between different sizing systems. Our Clothing Size Converter instantly converts between US, UK, EU, and International (XS-3XL) sizes for men's and women's clothing — including body measurements — all running in your browser.
Understanding Sizing Systems
US Sizing
US women's sizes use even numbers (0, 2, 4, 6, 8, 10, etc.) with the option of letter sizes (XS through 3XL). Men's tops use letter sizes (S, M, L, XL) while pants use waist measurements in inches (28, 30, 32, etc.).
UK Sizing
UK sizes differ from US sizes. For women, UK sizes are typically 4 numbers larger than US sizes — a US size 8 is approximately a UK size 12. For men, UK and US letter sizes are generally the same, though fit may vary.
EU Sizing
European sizes use larger numbers. Women's EU sizes typically range from 32 to 50+. Men's EU sizes range from 44 to 56+. Half of the EU number roughly corresponds to a US size, e.g., EU 38 ≈ US 6 for women.
International Sizing (XS-3XL)
The XS to 3XL system provides a simplified universal scale. However, these sizes are not standardized — a "Medium" from one brand may be a "Small" from another.
Size Charts
The converter includes detailed charts for:
- Men's Tops/Shirts: 7 sizes (XS-3XL) with chest measurements
- Men's Pants: 7 sizes (waist 28"-40") with US, UK, EU conversions
- Women's Tops: 10 sizes (US 0-18) with bust measurements
- Women's Dresses: 8 sizes (US 2-16) with bust, waist, and hip measurements
How to Measure
- Chest/Bust: Measure around the fullest part of your chest/bust with arms relaxed at your sides.
- Waist: Measure around your natural waistline — the narrowest part of your torso.
- Hips: Measure around the fullest part of your hips and buttocks.
- Tips: Stand in front of a mirror, keep the tape level and snug but not tight. Measure over light clothing or undergarments only.
Shopping Tips
- Brand variation: Sizes differ between brands. Always check the brand's specific chart.
- Read reviews: Online reviews often mention whether items run large or small.
- Check return policy: When buying internationally, ensure you can return for free if the size doesn't fit.
- Know your measurements: Body measurements in inches or centimeters are more reliable than size labels.
