Ring Sizing

In order to find the appropriate ring size, follow the instructions below. The chart on the right is for finding your ring size either from a ring you already own or by using a piece of string and a ruler. The chart below and to the left is for our international customers and allows for size conversions.

Ring Size Chart

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 millimeter measurements). Or, measure the diameter (distance across) in millimeters 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.)

An example of measuring the diameter of a ring. The inside of this ring is approximately 18mm in diameter, making it a size 7 on the chart below.


Ring Size Circumference (in mm) Diameter (in mm)
4 50 mm 16 mm
5 53 mm 17 mm
6 55 mm 17.5 mm
7 57 mm 18 mm
8 60 mm 19 mm
9 63 mm 20 mm
10 66 mm 21 mm
11 68 mm 21.5 mm
12 71 mm 22.5 mm
13 73 mm 23 mm
14 76 mm 24 mm
