Dress Size Converter
Convert women's dress sizes between the US, UK, EU, and Australian sizing scales.
Choose the system your dress size is in, then read across for the equivalent US, UK, EU, and Australian sizes. Australian dress sizes track the UK numbers closely, while EU sizes run on a separate scale.
These are standard chart conversions; the actual fit still depends on the brand and the cut of the dress. If you're between sizes or the style is fitted, checking the garment's bust and waist measurements beats trusting the number on the tag.
How it works
Buying a dress from an overseas label means decoding its size chart. This tool lines up the four scales you'll meet most — US, UK, EU, and Australia — on a single standard chart so you can jump between them.
Tell it which system your dress size is in and pick your number. It reads across the matching row and shows the equivalent in the other three at a glance.
Australian sizes track the UK numbers very closely, so an AU 12 and a UK 12 land in the same place, while the EU scale runs on its own higher set of numbers — a US 8 shows up as an EU 40.
Frequently asked questions
Is an Australian size the same as a UK size?
Almost. Australian women's dress sizing follows the UK numbers closely, so they usually match one to one. Small differences can still show up between individual brands.
Why is the EU number so much higher?
The EU scale is based on body measurements in centimeters, so its numbers naturally run larger. It's a different starting point, not a different fit — this tool maps it for you.
What if my size falls between two rows?
Dresses are less forgiving than tops, especially fitted styles. If you're between sizes, check the garment's bust and waist measurements and lean toward the size that matches your larger measurement.
