Ring Size Guide

To find your ring size simply measure the circumference (distance around) the knuckle of your finger with something flexible, such as a narrow strip of paper. You can also measure the inside diametre (distance across) in millimetres of a ring you currently wear.

Find the nearest measurement on the chart below to determine your approximate ring size. When in doubt between two sizes, it is always safer to go to the next larger ring size.
