Wondering if you’re actually a size 12 or a 14? Sizes seem to differ from store to store in the US alone, so online shopping opens up a whole new world of confusion with international sizing. To try and make sense of it – we’ve researched a few different sources and constructed a few handy conversion charts for all your international online shopping needs.

A few easy rules to remember:

  • S/M/L can vary hugely – always check the retailer’s own sizing chart
  • Add 2 sizes to get your UK size (for example, a US dress size 2 is a UK dress size 6)
  • French sizes are also used in Belgium and Portugal
  • German sizes are also used in Austria, Netherlands, Switzerland, Sweden, Denmark and Norway.
  • AU dress sizing is the same as UK

How to find your dress size?

The best way to determine your dress size is to use a conversion chart such as the ones above. These are based on our research across the web, but if a retailer you’re buying from has their own, it’s best to check that out. Use a tape measure to get accurate bust, waist and hip measurements at home.

What dress size is a ‘Medium’?

This varies from brand to brand and by country. Some stores will consider a medium to be a size 8, while others a size 10-12. As an average, a Medium is likely to be a around a size 10. This is all dependent on retailers, dress cut and shape — so we’d always recommend checking the store’s own sizing chart or using a retailer with free returns.

What dress size is plus size?

It absolutely depends on the retailers, but a lot of plus size-specific retailers will stock from a size 14 and up.
