Ring Size Guide

How to Determining Your Ring Size:

In North America, women’s rings generally range from size 3 to 9 while men’s rings usually range from size 8 to 14. If your ring size appears to be in between two sizes, it is recommended that you choose the larger size.

 

Ring Size Chart:

Measure the circumference (distance around) of your finger with a strip of paper, and a ruler with millimeter markings. Or, measure the diameter (distance across) in millimeters of a ring you currently wear. Find the nearest measurement on the chart below. Measure 3 to 4 times to help ensure an accurate reading, and make sure the ring you measure fits comfortably over your finger’s joint and rests snugly at the bottom of your finger.
