The right fit makes a ring comfortable to wear every day. Here is how to find your size at home, and what to do if you are between sizes.
Measure a Ring You Already Own
Place a ring that fits the intended finger on a ruler and measure the inside diameter in millimetres, from edge to edge. Match the measurement to the chart below.
Measure Your Finger
- Wrap a thin strip of paper or string snugly around the base of your finger.
- Mark where the ends meet, then measure the length in millimetres. This is your circumference.
- Measure at the end of the day, when fingers are at their largest, and make sure the strip can slide over your knuckle.

A Note on Eternity Bands
Because full eternity bands are set with diamonds all the way around, they generally cannot be resized significantly after they are made. If you are between sizes, choose the larger size, or book a consultation and we will help you confirm your fit before your band is made.
