Clothing Size Converter
Convert clothing sizes between US, UK, European and international systems.
The same garment, different labels
Clothing sizes are a tangle of regional systems — a US size, a UK size, a European number — that rarely line up, which makes buying from another country a guessing game. This converts clothing sizes across the main systems, so a size quoted one way gives you a starting point in the system you know.
Enter a size and see it across the systems.
Why sizing is only ever approximate
It has to be said plainly that clothing size conversion is a rough guide at best, because sizing is not standardised even within a single country — two brands can label the same measurements differently, and vanity sizing muddies it further. The one dependable approach is to work from actual body measurements against a brand's own size chart, which most retailers provide. Use the converted size to get in the right range, then check the specific garment's measurements, especially for anything fitted where a size out is the difference between a good fit and a return.
