How to find your ring size at home
Getting your ring size right before ordering is one of the most important steps you can take — especially when your ring is being made to order, just for you.
Method 1: string or paper
This is the easiest method and works well for most people.
- 1Cut a thin strip of paper or use a piece of string.
- 2Wrap it around the base of the finger you plan to wear the ring on.
- 3Mark where the paper or string meets.
- 4Measure that length in millimetres against a ruler.
- 5Compare to our ring size guide to find your AU/US size.
Method 2: measure an existing ring
If you already own a ring that fits well on the same finger, this is often the most accurate method.
- 1Place the ring flat on a ruler.
- 2Measure the inside diameter in millimetres.
- 3Compare to the inner diameter column in our size chart.

Tips for an accurate measurement
- Fingers are slightly larger in the evening and when warm. Measure at the end of the day for the most accurate result.
- If you are between sizes, size up.
- For wide bands, consider sizing up by half a size — they sit closer to the finger and can feel tighter than a standard band at the same measurement.

Frequently asked questions
How do I measure my ring size at home in Australia?
Wrap a thin strip of paper around the base of your finger, mark where it meets, and measure the length in millimetres. Use the conversion table above to find your AU/US ring size. Alternatively, measure the inside diameter of a ring that already fits.
What is the most common ring size for women in Australia?
The most common ring sizes for women in Australia are US 6 to US 7 (inner diameter 16.5mm to 17.3mm). However, ring size varies significantly — always measure rather than guess.
Is it better to size up or down if between sizes?
Size up. A ring that is slightly loose is easier to wear than one that is too tight. For wide-band rings, always size up by half a size.
