Ring Size Chart

There are two ways to measure your ring size at home.

Take an existing ring and measure its diameter across - or, measure around your finger - and then look up the corresponding ring size.

1. Wrap a narrow strip of paper or piece of string comfortably around your intended finger.

2. Mark the end (where it meets) and measure the distance. This is the circumference.

3. 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 size.

Pro tips for measuring:
-Measure your ring size at the end of the day when your fingers are at their largest.
-Make sure your hands are nice and warm. If you’re cold, your finger may be up to half a size smaller than normal.
-If using a measuring tape, or a ring sizer, make sure it fits comfortably enough not to slip off, but loose enough to slide over your knuckle.
-If buying a thicker ring we would recommend you go up a size.
