Don't Know what size ring you wear? Use one of these charts or guages to order the right size!
Remember, the wider the ring, the higher up on your finger you want to measure.
To find your ring size: Simply measure the circumference (distance around) your finger (with something flexible, such as a strip of paper or piece of string, and a ruler with millimetre measurements). Or, measure the diameter (distance across) in millimetre of a ring you currently wear. Find the nearest measurement on the chart below. That's approximately your ring size. (When in doubt between two sizes, it is always safer to go to the next larger ring size. This ensures your new ring will fit you.)

Determine Ring Size With a Ring Size Chart
Use a ring that fits you to determine your ring size. Place your ring over the nearest size circle. The inner edge of the ring should align with the outer edge of the circle. If your ring appears to fit between two sizes, buy the larger size.
