RING SIZE GUIDE

How to measure your ring size

You can measure your ring size using the internal diameter of a ring (take an existing ring and measure its diameter across from each side of the ring) or circumference (measuring around your finger) as follows:

Wrap a narrow strip of paper or piece of string comfortably around your intended finger.
Mark the end (where it meets) and measure the distance. This is the circumference.
Match the measurement to the circumference column in the ring size chart below. If it falls between 2 sizes, we recommend getting the larger size.
