Ring sizes

We use Australian ring size measurements, which are in an alphabetical range from A-Z.

As your fingers contract and expand due to the temperature, humidity, exercise, etc, your ring will fit on your finger tighter or looser. Your ring should fit comfortably and you need to find a balance between too big and too small. It is recommended that you should have to push your ring on tightly over your knuckle and it should spin slightly around the base of your finger. There should be some resistance when the ring is taken off – this will help to keep the ring on when your fingers are cold or wet. The correct size is the one that you feel the most confident and comfortable with.

We suggest that you size the finger you intend to wear your ring on at room temperature – this should provide you with a size that should be close to perfect most of the time.

Top-heavy rings can tend to spin on your finger, as the base of your finger is usually thinner than your knuckle. We suggest when sizing your finger for a top-heavy ring, that you err on the tighter side, rather than a loose fit. This will mean that the ring will stay on the top of your finger and it will ultimately be more comfortable to wear.

If you’re choosing a wide ring, you will tend to go up a size. There is more surface area on a wider ring and therefore more metal to grip to your finger.

If you are interested in a ring that is 5mm or wider, we suggest going up a size (one size larger than the sizing gauge). We suggest going up another size if the ring you are interested in is 9mm or larger (two sizes larger than the sizing gauge).

If you are buying a ring as a gift for someone, we recommend that you measure the inside diameter of a ring the person you’re buying the gift for, regularly wears on the finger your gift will be worn on.

Measuring your finger

If you do not know your ring size you can use this guide to obtain an approximate measurement.

The number that lines up with edges of the opening is the ‘interior circumference’. Please note this number and then refer to our
