# Clothing Size Converter: Complete International Guide
Buying clothes from international stores can be confusing when sizes do not match. The clothing size converter helps you find your perfect size across EU, US, UK and IT systems, for shirts, pants, dresses and jackets.
# Why do clothing sizes vary between countries?
There is no single international standard for clothing sizes. Each region developed its own system, creating confusion when shopping from foreign stores or platforms like Amazon.
- EU sizes (Europe): Use progressive numbers (XS, S, M, L or 32, 34, 36...). The most common system in Spain and Italy.
- US sizes (United States): Use letters (XS, S, M, L) or numbers for women's pants (0, 2, 4, 6).
- UK sizes (United Kingdom): Similar to EU but with its own numbering, generally lower than US.
- IT sizes (Italy): Italian numbering with variations from the general EU system.
Professional Tip
Sizes vary significantly between brands. A size 38 in Zara can be different from a 38 in H&M. Always check the store's specific size chart before purchasing.# How to measure your body correctly
To guarantee the right size, measure your body with a flexible tape measure. Measure at the end of the day, when your body is at its maximum expansion.
- Chest: Measure around the widest part of your chest, passing the tape under your arms.
- Waist: Measure at navel height without artificially holding in your stomach.
- Hip: Measure around the widest part of your hips, keeping the tape parallel to the floor.
# Brand fit guide
- Zara: Regular sizing. A 36 in Zara is generally reliable for standard measurements.
- H&M: Tends to run large. Consider sizing down from your usual size.
- Uniqlo: Runs small, especially in basics. Sizing up is recommended.
- Nike / Adidas: Athletic, close-fitting cuts. Consider going up half a size.
