About this tool
This follows commonly published general size charts for women's and men's clothing. Clothing sizing is the least standardised of all the sizing systems on this site — it varies not just by country but by garment type, cut, and brand (a US size 8 dress and a US size 8 pair of jeans aren't guaranteed to fit the same body the same way), so treat this as a general starting point for comparing size labels across regions, not a precise fit guarantee.

Questions about clothing sizes
What is a UK size 12 in US and EU sizes?
For women’s clothing, a UK 12 is usually a US 8 and an EU 40. Check the result above for other sizes.
Are US and UK women’s sizes different?
Yes. US sizes are usually 4 lower than UK sizes, so a UK 10 is a US 6.
Why do sizes vary between brands?
Clothing sizes aren’t standardised, so cuts and brands differ. Use this as a starting point and check the brand’s own size chart, especially when buying online.
How do I find my size if I’m between two?
Compare your measurements with the brand’s chart. For fitted clothes, the larger size is often the safer choice.
