You can measure your ring size in a number of ways. In the UK it is measured alphabetically, in the US it is done numerically, or you can measure the Internal Diameter or Circumference.

Our guide is on hand to take the guesswork out of ring shopping.

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

How do I measure my ring 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.
- 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.

How do I measure a ring I already own?

How to measure the Inside Diameter of your Ring:
- 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 then you should opt for the larger size.
