UK vs USA vs EU Sizing – What’s the Difference & How to Find Your True Size

If you've ever been confused when buying clothes internationally, you're not alone. A UK size 12 doesn’t match a US 12, and EU sizes add another layer of complexity. With fashion brands using their own fit systems on top of regional sizing differences, navigating clothing sizes can feel impossible.

This guide breaks down the technical differences between UK, US, and EU sizing for women’s clothing—and shows you how to find your exact size across all brands and countries using tellar.co.uk, the UK’s leading free sizing tool.

🔢 Key Differences Between UK, USA & EU Clothing Sizes

🇬🇧 UK Sizing

• UK sizes are based on body measurements in inches.

• Common sizes range from UK 4 (XXS) to UK 30 (5XL).

• UK brands like M&S, Reiss, Next, and Whistles use this system.

• A UK size is usually 2 sizes smaller than a US size.

🇺🇸 US Sizing

• US women’s sizes typically range from 0 to 24.

• A US 6 ≈ UK 10.

• Many US brands like J.Crew, Anthropologie, and Eloquii use vanity sizing, where the number appears smaller for marketing purposes.

🇪🇺 EU Sizing

• EU sizes are based on body circumference in centimetres.

• An EU 36 ≈ UK 8 / US 4.

• Common sizing ranges: EU 32–54 for women.

• Brands like H&M, Zara, and Mango (which sell globally) often display both EU and UK/US sizes on their labels.
