How to measure your ring finger:

- Wrap a narrow strip of paper or piece of string comfortably around your intended finger.
- Mark the end (where the paper or string meets) and measure the distance. This is your finger circumference.
- Match the measurement to the circumference column in the above conversion table. If it falls between two  sizes, we advise you to order the larger size.

How to measure a ring you already own:

- Select one of your rings that properly fits the intended finger.
- Measure the INSIDE diameter of the ring using our helpful Printable Ring Sizing Guide.
- Match the measurement of your ring against one of the images. If it falls somewhere in between two sizes, we advise you to order the larger size.
