Pick the size system you know, choose your size, and see the matching size in US, UK, EU, and Australian sizing, plus the usual letter size. These are typical conversions: brands differ, so always check the retailer’s own size chart before you buy.
Convert your dress size
Letter sizes are approximate and vary the most from brand to brand. If you are between sizes, check the fabric: a fabric with stretch often forgives a smaller size, while a woven fabric with no stretch usually calls for the larger one.
Why sizes differ between countries
There is no single international standard for women’s clothing. Sizes move in steps of two in every system. Compared with the US, UK and Australian numbers run four higher, and European sizes run thirty-two higher. Within each country, brands also cut the same number differently, which is why a US 8 can fit like a 6 in one store and a 10 in another.
Get the best fit when ordering online
- Take your bust, waist, and hip measurements and compare them with the brand’s own chart rather than relying on the number alone.
- Read reviews for comments like “runs small” or “true to size”.
- Check the fabric content and whether the garment has stretch.
Frequently asked questions
What is a US size 8 in UK and EU sizes?
A US 8 is typically a UK 12, an EU 40, and an Australian 12. The usual letter size is medium.
Why does my size change from brand to brand?
Brands use their own fit models and sizing standards, and many have grown their sizes over the years, a practice often called vanity sizing. Use each brand’s measurement chart whenever one is available.
Is this converter for shoes too?
No, shoes use different numbering. Use the Shoe Size Converter for that.
Should I buy by size or by measurements?
Measurements are more reliable. Use this converter to get close, then confirm against the brand’s own chart.
