The ultimate guide to dress size conversion

Wondering if you’re actually a size 8 or a 10? Sizes seem to differ from store to store in Canada 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:

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

If you’re shopping for a dress, why not take a peek at our top sales and discount codes. Maybe the dress you want is on sale!

What clothes size should I be for my height?

There is no specific size you should be for your height, your overall health cannot be determined by dress size alone, so it’s best to see a doctor if you want advice on what a healthy size would be for you. The average height and weight for a woman in Canada is 155lb and about 161cm tall.


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 6, while others a size 8-10. As an average, a Medium is likely to be a around a size 8. Generally a Small will be a Canadian size 2-4 and a Large a Canadian 10-12. An Extra Small is likely to be a size 0, with an Extra Large likely to be a size 14. This is all dependent on retailers, dress cut, shape and fit — so we’d always recommend trying a dress on, 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 Canada and US-based plus size-specific retailers will stock from a size 12 or 14.
