Whether you are buying the ring for someone else or yourself, we realise that you may not know which ring size to purchase. To help you, we've prepared a simple guide to determine which ring size will fit your finger.

• Your ring should fit your finger comfortably: snug enough so that it will not fall off, but loose enough to slide over your knuckle.
• Measure finger size several times to eliminate an erroneous reading.

Method: Measure an existing ring

Print this page, ensuring that page scaling is set to none in the print dialog box.
Measure the bar on the right and make sure it measures exactly 30mm.

Select a ring that properly fits the intended finger. Place the ring over the circles below, lining up the inside edge of the ring with the circle nearest in size. This measurement refers to the inside diameter of the ring. If your size is between two sizes, opt for the larger of the two.
