Australian Size Converter (AU → US, UK, EU)
This Australian size converter handles the AU-vs-UK-vs-US differences most calculators flatten. Australian sizing matches UK for clothing (AU 8 = UK 8 = US 4) but shoe sizing has a 0.5–1 size offset, and brands like Zimmermann and Cue use Australian-specific cuts. Enter the AU size and get accurate US, UK, EU equivalents. Use the calculator below to get your exact fit in 30 seconds.
