Australian Shoe Size Conversion

Why You Need an Australian Shoe Size Converter

Shopping for shoes from Australian brands or retailers can be confusing without understanding AU (Australian) shoe sizing. Unlike some countries that use purely metric measurements, Australian sizing follows a numbered system similar to both UK and US sizing—but with important differences. Our free Australian shoe size converter eliminates the confusion by instantly translating AU sizes to all major international systems: US, UK, EU, CN, and JP.

Australian footwear brands like R.M. Williams, Blundstone, Ugg Australia, and others are renowned worldwide for quality craftsmanship. However, their primary sizing system is AU, which can confuse international shoppers. Understanding AU conversions is essential whether you're an American buying iconic Blundstone boots, a European ordering R.M. Williams Chelsea boots, or an Australian shopping from international retailers.

Understanding Australian (AU) Shoe Sizing

Australian shoe sizing has a unique dual relationship with other sizing systems. For men's shoes, AU sizing is identical to UK sizing—an AU 9 equals a UK 9. This is because Australian shoe manufacturing historically followed British standards. However, for women's shoes, AU sizing is much closer to US sizing, with AU 8 being approximately US 8. This dual alignment makes AU sizing unique among international systems.

Common AU size ranges are: Women's AU 5-12 (closely matching US 5-12), Men's AU 6-15 (identical to UK 6-15), and Kids' AU 4-13 (varies by age group). The system uses whole and half sizes, providing precise fit options. Understanding these ranges helps when shopping Australian brands or when Australian retailers list sizing.

How to Use This Australian Shoe Size Converter

Using our Australian shoe size converter is simple and accurate. First, select your gender (men's, women's, or kids'). For kids, choose the appropriate age group as sizing differs for toddlers, little kids, and big kids. Next, select your Australian (AU) shoe size from the dropdown. The converter instantly shows your equivalent sizes in US, UK, EU, CN, and Japanese (JP) systems.

For the most accurate results, measure your foot length before shopping. Stand on a piece of paper against a wall, mark the longest point of your foot, and measure from the wall to the mark in centimeters. Women's AU 8 corresponds to approximately 25cm foot length, while Men's AU 9 corresponds to approximately 27cm. Always round up if you're between sizes, as it's easier to add an insole than deal with tight shoes.

Common Australian Shoe Size Conversions

Some of the most frequently searched Australian shoe size conversions include: AU 7 = US 7 = UK 5 = EU 37.5 (Women's). AU 8 = US 8 = UK 6 = EU 38.5 (Women's). AU 9 = US 9 = UK 7 = EU 39.5 (Women's). For men's shoes: AU 8 = US 8 = UK 7.5 = EU 41. AU 9 = US 9 = UK 8.5 = EU 42.5. AU 10 = US 10 = UK 9.5 = EU 44.

These are standard industry conversions based on foot length measurements and traditional last sizes. However, individual brands—especially Australian heritage brands—may vary slightly. Always check the specific brand's size chart when available. Blundstone, for example, often recommends sizing down 0.5 from your sneaker size due to their generous fit. R.M. Williams boots typically run true to AU size with excellent consistency.

Shopping Australian Brands Internationally

When shopping iconic Australian footwear brands from overseas, understanding AU sizing prevents costly mistakes. R.M. Williams Chelsea boots use AU sizing and are known for running true to size—an AU 9 fits like a UK 9 for men. Blundstone elastic-sided boots also use AU sizing, but many customers recommend sizing down 0.5 as they run slightly large and the leather stretches with wear. Ugg Australia slippers and boots use AU sizing and generally run true to size, though the sheepskin lining may compress slightly over time.

Pro tips for shopping Australian brands internationally: (1) Always check the brand's official size chart—AU sizing is consistent, but last shapes vary. (2) Read customer reviews from shoppers in your country about fit. (3) When buying boots like Blundstones or R.M. Williams, consider sock thickness—thicker socks require slightly larger sizing. (4) Contact the retailer with your exact foot measurement in centimeters for personalized sizing advice. (5) Use FitSwapr's virtual try-on to visualize how shoes will look before committing to international shipping costs.
