Understanding Australian Ring Sizes
Australia uses the UK letter ring sizing system, a heritage from British colonial history that continues to be the standard sizing method across the country. Ring sizes in Australia are designated by letters from A to Z, with A being the smallest and Z being the largest. This alphabetic system is unique among major sizing systems and is used consistently across all Australian jewelry retailers and jewelers.
The letter system is actually quite straightforward once you understand the baseline. Each letter represents a specific inner circumference measurement, similar to how other countries use numeric systems. The advantage of the letter system is its memorable nature—it's easy to recall whether you're a size H, M, or S. Australian consumers have grown familiar with this system, and it remains the standard despite Australia's geographic isolation from other letter-system countries.
The UK letter system is identical in Australia, which means Australian residents can easily purchase rings from UK retailers and vice versa. This shared sizing system has created convenient cross-border shopping opportunities and makes conversions between Australia and the UK straightforward—no conversion needed, just a direct size match.
Historical Context: British Colonial Influence
Australia's adoption of the UK ring sizing system stems directly from the country's history as a British colony. When Australia was colonized and developed its commercial systems, it adopted British standards across many industries, including jewelry. The UK letter system was the established standard at that time and became deeply integrated into Australian jewelry retail practices.
This historical connection means that Australian and UK ring sizes are completely compatible. An Australian woman wearing size M can purchase from a UK retailer and receive exactly the same size designation. This compatibility has lasted over a century and continues today despite both countries being independent nations with their own standards in other areas.
The persistence of the letter system in Australia demonstrates the enduring influence of colonial-era standards. While the US and most of Europe adopted numeric sizing systems, Australia and the UK maintained the letter system, creating a unique geographic clustering of shared sizing standards.
How the Australian Letter System Works
The Australian letter ring sizing system uses letters A through Z to denote ring sizes in ascending order of circumference. Each letter corresponds to a specific inner ring diameter and circumference measurement. The system provides 26 distinct sizes, which covers the vast majority of ring sizing needs for the population.
| UK/AU Size | Inner Diameter (mm) | US Size | EU Size |
|---|---|---|---|
| B | 14.0 mm | 2.75 | EU 44 |
| D | 14.9 mm | 3.5 | EU 46 |
| H | 16.5 mm | 5.5 | EU 50 |
| M | 18.3 mm | 7.5 | EU 54 |
| R | 20.1 mm | 9.5 | EU 60 |
| V | 21.4 mm | 11 | EU 64 |
| Z | 23.0 mm | 13 | EU 70 |
The letter system's progression through the alphabet makes it intuitive for Australians familiar with their sizing. Each step up the alphabet represents approximately a 0.5-size increase in US measurements, making the progression consistent and predictable.
Average Ring Sizes in Australia
Understanding average ring sizes worn by Australians helps provide context when shopping or converting sizes. Australian hand sizes follow patterns similar to other Western populations, with some variation based on demographics.
Women: Average Australian women typically wear sizes L to N, with M being the most common. This corresponds to US sizes 6-8.
Men: Average Australian men typically wear sizes R to T, with S being most common. This corresponds to US sizes 9.5-11.
Regional variation: Slight variations exist across different regions and demographic groups in Australia.
Full range: Sizes available range from A (smallest) to Z (largest), accommodating all hand sizes.
These averages are helpful for general reference, but individual measurement is always the most reliable way to find your perfect ring size.

Get Professional In-Store Sizing
Visit a major jewelry retailer for professional sizing. Most Australian jewelers offer free sizing services and can provide accurate letter-system measurements for your finger.
Remember the UK Equivalence
Your Australian size is identical to the UK size. If you know your UK size from previous purchases, it will be the same in Australia. This opens up UK retailers for shopping options.
Convert from Other Systems
If you know your US or EU size, use our US to UK ring size converter to find your Australian letter size.
Consider Ring Width Effects
Wider rings may require a larger size than narrower bands. Always specify the desired ring width when being sized.
Check Online Return Policies
Australian online retailers typically offer return periods for sizing errors. Verify the policy before purchasing, especially from international retailers.
Visit Major Shopping Areas
Shopping precincts in Sydney, Melbourne, Brisbane, and Perth offer multiple jewelry retailers where you can compare quality, pricing, and sizing expertise.
Unique Advantages of the Letter System
The letter ring sizing system offers several unique advantages that have contributed to its persistence in Australia:
Easy to remember: Letter sizes are more memorable than numeric systems. You're more likely to remember you're a size M than size 54.
Universal across retailers: All Australian retailers use the same letter system, making shopping consistent whether you visit Michael Hill, Cerrone, or independent jewelers.
Easy UK shopping: Your Australian size directly equals your UK size, eliminating conversion confusion when ordering from British retailers.
26-size range: The alphabet provides 26 distinct sizes, sufficient to accommodate virtually all hand sizes in the population.
Despite globalization and the dominance of numeric systems elsewhere, the letter system has remained remarkably consistent in Australia because of its practical advantages and entrenched retail infrastructure.
