Each size below has its own page with the answer, the letter size, the bust and waist measurements and the sizes either side.
UK and US women's sizes are two labels for the same body measurements. The chart lines up each UK size with its US equivalent using the bust measurement in centimetres, the one figure that does not change between systems. Brands still vary in how generously they cut a given size, so treat the label as a starting point and the measurement as the confirmation.
The lookups people search for most on this route: a UK 8 is a US 4 (size S, 86 to 89 cm bust), a UK 12 is a US 8 (size M, 94 to 97 cm), and a UK 20 is a US 16 (size XL, 111 to 116 cm).
This chart is checked against the widely published international women's clothing conversion tables (the same US, UK, EU, Italy and France figures referenced on Wikipedia's clothing sizes overview) and follows the general body-measurement approach behind the EN 13402 European sizing standard. For men's chest-based sizing, see the men's clothing size chart, and for kids, the youth clothing size chart. To measure yourself accurately, see how to measure clothing size.
Common questions
What is a UK 12 in US clothing sizes?
A UK 12 is a US 8, a size M with a bust of about 94 to 97 cm.
How do I convert a UK clothing size to US?
Find your UK size in the chart and read across to the US column, or match your bust measurement in centimetres directly. Fit still varies by brand, so measuring is the most reliable check.
Is this chart for men's or women's sizes?
This chart covers women's tops and dresses. Men's sizing runs on a different chest-based scale: see the men's clothing size chart instead.
What if my measurement falls between two sizes?
Size up for wovens like dresses and jackets, and consider sizing down one for stretch knits, since stretch fabric has more give at the smaller size.
