Engagement Ring Size Guide Australia
Finding the perfect engagement ring starts with choosing the correct ring size. Whether you're planning a surprise proposal or shopping together, ensuring the ring fits comfortably is just as important as selecting the diamond or design.
At Alexander Jewellers, we've helped thousands of Australians find the perfect engagement ring. This comprehensive guide explains how to measure your ring size, understand Australian sizing and avoid common sizing mistakes.
Why Ring Size Matters
An engagement ring should feel secure without being too tight or too loose. A correctly sized ring should slide over the knuckle with slight resistance and sit comfortably throughout the day.
A ring that is too loose may fall off, while one that is too tight can become uncomfortable and difficult to remove.

How to Measure Your Ring Size at Home
Method 1: Measure an Existing Ring
If you already own a ring that fits comfortably on the intended finger, measure the inside diameter using a ruler or callipers and compare it with the chart above.
Method 2: Use String or Paper
- Wrap a thin strip of paper or string around your finger.
- Mark where the ends meet.
- Measure the length in millimetres.
- Compare your measurement with an Australian ring size chart.
Method 3: Visit a Professional Jeweller
The most accurate way to determine your ring size is to have it measured professionally. At Alexander Jewellers, we provide complimentary ring sizing in-store.
Average Ring Sizes in Australia
- Women: Size L to N
- Men: Size R to T
These are averages only. Finger sizes vary significantly between individuals.
Tips for Choosing the Correct Ring Size
- Measure your finger at room temperature.
- Avoid measuring immediately after exercise.
- Measure at the end of the day when fingers are at their largest.
- If you're between sizes, choose the slightly larger size.
- Consider the width of the ring, as wider bands often require a larger size.
Planning a Surprise Proposal?
If you're keeping the proposal a surprise, try one of these methods:
- Borrow a ring they already wear on the correct finger.
- Ask a family member or close friend.
- Compare their finger to your own.
- Take a clear photo of them wearing a ring and speak with our jewellers.
If the ring isn't perfect, don't worry. Many engagement rings can be professionally resized after the proposal.
Can Engagement Rings Be Resized?
Yes. Most gold and platinum engagement rings can be resized by a professional jeweller.
Some designs, such as eternity rings or rings with intricate settings, may have resizing limitations. Our jewellers can advise on the best solution for your ring.
