Quick answer

Clothing size conversion is a guide, not a guarantee. A UK 12 women’s size is often close to a US 8 and EU 40, but brand fit, cut and measurements can change the best size.

Tip: Always check the retailer’s own size chart if you are buying clothing online, especially for fitted items.

FAQs

Are clothing size conversions exact?

No. They are approximate because each brand can use its own fit model and measurements.

Is a UK size always smaller than a US size?

For many women’s clothing sizes, UK numbers are often about 4 higher than US numbers, but this is only a guide.

Should I use measurements instead?

Yes. For important purchases, chest, waist, hip and inside-leg measurements are more reliable than label conversion.
