Australian to US women’s clothing sizes
Take 4 off an Australian women’s size to get the US size: an AU 10 is a US 6, and an AU 12 is a US 8. Australian clothing sizes use the same numbers as UK sizes in every source we checked.
This page is for dresses, tops, coats and other womenswear labelled in numbers. It does not cover shoes or jeans labelled by waist.

Where the charts disagree
- AU and UK: every source we checked prints AU and UK sizes as the same number, so an AU 12 is a UK 12.
- The smallest size: at AU 4, ASOS prints US 1 while the other sources print US 0.
- Shoes are different. This table is for clothing only; our sources do not publish a consistent Australian shoe column.
Why brands still vary
A conversion maps one label to another. It cannot know how a particular brand has cut and graded its sizes.
- Labels drift. Vanity sizing means the same number can describe a larger garment than it did years ago, and brands do not drift at the same pace.
- Body and garment measurements differ. A body chart says which body a size is meant for; a garment chart measures the finished item.
- Cut and fabric change the answer. A slim cut, a relaxed coat and a stretch fabric can carry the same label and leave very different room.
How to measure yourself
A conversion only shortlists a size. Your own measurements in centimetres, checked against the brand's size chart, decide it.
- Bust: measure around the fullest part, keeping the tape level under your arms.
- Waist: measure around the narrowest part of your natural waist, usually just above the belly button.
- Hips: stand with your feet together and measure around the fullest part of your hips and seat.
Keep the tape snug but not tight. Then check whether the brand's chart shows body or garment measurements. Our explainer on what "true to size" means covers fit notes such as "runs small".
A note for merchants
Shoppers search for conversions because a single size label does not tell them how an item will fit. If you sell clothes or shoes online, publish a size chart in centimetres for each product, say whether it shows body or garment measurements, and add a short fit note. A free size chart template is a quick place to start. On Shopify, Rendered Fits recommends a size for each product from your own size chart, so shoppers do not need a converter; there is a Free plan.
