Australian clothing sizes are typically 4 sizes higher than US sizes for women — an AU 10 equals a US 6. Knowing this rule prevents costly returns when shopping from US retailers like Gap, Nordstrom, or American Eagle. Our tool is perfect for Australians shopping internationally or Americans buying from Australian brands in 2026.
Select your clothing category, then choose your AU size
Australian and US clothing sizes follow the same numeric pattern but are offset by a fixed number. For women's clothing, Australian sizes run 4 sizes higher than their US equivalents — so an AU 10 equals a US 6, and an AU 14 equals a US 10. This means Australians shopping from US stores like Gap, Banana Republic, or J.Crew need to size down by 4 from their usual AU size to find the right fit.
For men's clothing, the good news is that Australia and the US share the same letter-based sizing system (XS, S, M, L, XL). A man who wears a medium in Australia will generally wear a medium in the US too. The key differences emerge in specific measurements like chest, waist, and inseam length, where minor brand-to-brand variations exist. Shoe sizes are where it gets more nuanced — Australian women's shoes are typically 1.5 to 2 sizes smaller than the US equivalent, while men's shoes differ by about 0.5 of a size.
Australian size 12 is the most common reference size — equivalent to US 8, UK 12, and EU 40.
This is the complete women's AU to US clothing size conversion chart covering standard sizes from AU 4 (XXS) through AU 22 (4XL). Use this as a quick reference when shopping from US fashion websites or buying Australian labels abroad.

For women's clothing, Australian sizes are consistently 4 numbers higher than US sizes across all standard sizes. An Australian size 8 is a US size 4, AU 12 is US 8, and AU 16 is US 12. This offset is fixed and applies to dresses, tops, skirts, pants, and swimwear from virtually all mainstream Australian and US fashion retailers in 2026.
Australian clothing sizes are identical to UK sizes for both men and women. This is a legacy of Australia's historical adoption of the British Imperial system. A shopper who wears a size 12 in Australia will wear a size 12 in the UK. However, the US developed its own independent sizing system, creating the 4-size offset that confuses shoppers buying cross-border clothing online today.
Australian women's shoe sizes differ from US sizes by approximately 1.5 to 2 sizes, while men's differ by just 0.5. For example, an AU women's size 7 = US size 8.5, but an AU men's size 10 = US size 10.5. Always check the specific brand's sizing chart when purchasing shoes online, as some US brands use slightly different offsets from the standard conversion.
While size charts are a great starting point, garment fit can vary significantly between brands and styles — even within the same country. When shopping online, always cross-reference the bust, waist, and hip measurements in centimetres listed in the product size guide rather than relying solely on the size number. This is especially important for formalwear, swimwear, and jeans.
For men's dress shirts, both Australia and the US use collar size in inches combined with sleeve length — for example, "15.5 / 33." This system is identical between the two countries, so a man who wears a 16/34 collar/sleeve in Australia will wear the same in the US. Always verify that the brand uses inches (not centimetres) before ordering formal dress shirts internationally.
Both Australian and US jeans brands typically use the same waist × inseam in inches labelling system — for example, 30×32. This means jeans sizing is directly interchangeable between the two countries without conversion. A man wearing 32×30 jeans in Australia will wear 32×30 in the US. Women's jeans in both countries also commonly use the same numeric waist sizing (24 to 34).
While the AU to US size conversion rule of subtract 4 for women's clothing applies to most mainstream brands, individual labels can vary. High-fashion brands, plus-size ranges, and activewear brands may use different fit standards. Before completing an online purchase, always check the specific retailer's own size guide and compare your actual body measurements in centimetres against the brand's listed garment measurements for the most accurate result.
These are the most frequently searched AU to US clothing size conversions used by Australian shoppers buying from US websites like Gap, ASOS US, Anthropologie, and Nordstrom.
