You can measure your ring size in a number of ways. We advise you to measure your ring size by the Internal Diameter or Circumference.

Measure your finger

• 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. Consider that you’ll need to take the ring off when sizing like this (not too tight), and of course you won’t want it slipping off either (not too loose). If it falls between 2 sizes, we advise you to order the larger size.
• Match the circumfence with your ring size using the below chart.

Measure an existing ring

If you already have a ring that fits, you can measure the diameter of the ring (e.g. from the inside of one side, directly across to the inside of the other). Use the below chart to determine your ring size.
