The Ultimate Ring Size Guide: How to Find Your Perfect Fit

Choosing a ring is an exciting experience—whether it's for an engagement, wedding, or a meaningful gift. But before you fall in love with the perfect design, one important detail must be sorted out: your ring size.

At Rings of Australia, we understand how crucial it is to find the perfect ring size—not just for comfort, but also for the peace of mind that comes with knowing your precious ring will stay securely on your finger for years to come.

In this Ultimate Ring Size Guide, we’ll walk you through everything you need to know about finding your ideal fit, from understanding how ring sizing works to tips on how to measure ring size at home. Plus, we’ll answer the most frequently searched questions around ring sizing to ensure you feel confident before making your purchase.

Why Ring Size Matters

Getting the correct ring size is essential. A ring that’s too tight can be uncomfortable, while a loose one risks falling off. When you're investing in fine jewellery—especially engagement or wedding rings—getting the fit right is as important as choosing the stone or setting.

Whether you’re shopping for a diamond engagement ring, a wedding band, or a statement piece, using this ring sizing guide will ensure your experience is smooth and enjoyable.

How Are Ring Sizes Measured?

Ring sizes are typically measured in numbers and vary slightly across different countries. In Australia, ring sizes use an alphabetical system (e.g., H, I, J, K, etc.), while countries like the US and Canada use numbers (e.g., 6, 7, 8).

Here at Rings of Australia, we use the Australian ring size chart, which provides a precise and easy-to-follow measurement system.

How to Measure Ring Size at Home

You don’t need to visit a jeweller to find out your size—there are several easy methods to measure ring size at home.

1. Use a Ring Size Chart

Download our free ring size chart at Rings of Australia and match your existing ring to the right size using our printable guide.

2. String or Paper Method

Wrap a piece of string or strip of paper around the base of your finger. Mark the point where it overlaps, measure the length in millimetres, and compare it to a ring size chart.

3. Use a Ring Sizer Tool

Ring sizer tools are inexpensive and easy to use. We recommend investing in one for the most accurate at-home measurement.

Pro Tip: Measure your finger at the end of the day, when it’s at its largest, and avoid sizing your finger when it’s cold.

Things to Consider When Choosing Ring Size

Finger Size Can Change

Fingers swell in heat and shrink in the cold. Keep this in mind when measuring.

Band Width Matters

Wider bands tend to feel tighter. If you're selecting a thick band, consider going up half a size.

Is the Ring Resizable?

Some ring designs are easier to resize than others. Ask us at Rings of Australia whether your chosen style allows for future resizing.

For Surprise Proposals

If you're planning a surprise proposal, borrow a ring your partner wears on the correct finger and use our free ring size chart to match it—or ask a close friend or family member for help.
