Clothing Size Converter
Select a US women's clothing size to see its UK, EU, and Italian equivalents.
Based on standard women's clothing size charts. Individual brands may size differently.
How international clothing sizes compare
Clothing size numbering differs by region because each system developed independently. US and UK sizes both use numbers, but UK sizes typically run about 4 sizes higher than the equivalent US number for women's clothing. EU and Italian sizes use a different, larger numbering scale entirely.
These conversions are based on standard published size charts, but actual fit varies significantly between brands, cuts, and garment types — always check a specific brand's own size chart when available, especially for a precise or first-time purchase.
Frequently asked questions
Why is a UK size different from the same-looking US size?
US and UK women's clothing sizing both use similar small numbers, but they're offset — a US size 8 is roughly a UK size 12, not UK 8, because the two systems' numbering scales were standardized independently and don't align.
Why do these conversions sometimes not match what I see in a store?
This chart reflects general industry standards, but individual brands routinely size up or down from the standard — a phenomenon often called "vanity sizing." Always use a specific retailer's own size chart for the most accurate fit.
Does this work for men's clothing sizes too?
No — this chart is for women's clothing sizes specifically. Men's sizing typically uses different numbering (like chest measurements or letter sizes) with its own international conversions.
