Size Guides
Method 1: Use an Existing Ring
Take an existing ring and measure its diameter across.
Method 2: Measure the Intended Finger
- Wrap a narrow strip of paper or piece of non-elastic string comfortably around the widest part of your intended finger. Sometimes, the widest part can be the knuckles.
- Mark the ends and measure the distance.
- Match the measurement to the circumference column in the above conversion chart. If it falls between 2 sizes, we advise you to order the larger sizes.
