Size Translator

One body, four numbers

Women’s sizes use different number systems in different countries. Your body hasn’t changed - only the label has. Once you know the pattern, shopping overseas sites (or op-shopping a US brand in Brisbane) gets easy.

Dresses, tops and skirts

AU	UK	US	EU
6	6	2	34
8	8	4	36
10	10	6	38
12	12	8	40
14	14	10	42
16	16	12	44
18	18	14	46
20	20	16	48
22	22	18	50

The pattern: AU and UK are the same. US is 4 less. EU is AU + 28. Some brands use letters instead (XS–XXL), and those vary wildly - always check the brand’s own chart against your measurements.

Shoes

AU / US women’s	UK	EU (approx.)
7	5	38
8	6	39
9	7	40
10	8	41–42
11	9	42–43
12	10	43–44

The pattern: AU and US women’s sizes are basically the same; UK is 2 less. EU sizes go by length and vary a bit by brand, so check the centimetre measurement when you can.

Bras (bands)

AU	UK / US	EU
10	32	70
12	34	75
14	36	80
16	38	85
18	40	90
20	42	95

The pattern: AU band + 22 = UK/US band. EU goes up in 5s. Cup letters match up to D, then split (AU/UK go DD, E, F, FF… while US often goes DD/E, DDD/F, G…). You’ll learn more in Bra Basics.
