How to Calculate & Formula Details

Mathematical Model FormulaApproximate conversions based on standard published international clothing size charts.

A clothing size converter helps you translate sizing between US, UK, and EU standards when shopping from international brands or retailers.

Why Sizes Differ by Region

US, UK, and EU clothing sizes each follow different numbering conventions. EU sizes are typically larger numbers than US sizes for the same fit (e.g., a US size 8 is often an EU size 38-40), and UK sizing frequently sits close to US numbering but not identically.

Note on Accuracy

Clothing size conversions are approximate guides, since actual fit varies significantly by brand, cut, and garment type. Always check the specific brand's size chart when available.

Frequently Asked Questions

Is a US size 8 the same as a UK size 8?

No. A US size 8 typically corresponds to roughly a UK size 10-12 for women's clothing, since UK sizing runs differently from US sizing.

Why do clothing sizes vary between brands?

There is no single universal standard for clothing sizing, so brands use their own measurements and cuts, causing the same labeled size to fit differently across brands.

What is EU clothing sizing based on?

EU sizing is generally based on body measurements in centimeters, resulting in larger numeric labels than US sizing for the same actual fit.
