Ring sizes
To find your perfect ring size in the US system, please follow one of the steps below:
-
Measure Your Finger Circumference (in mm)
Use a soft measuring tape to wrap around the base of your finger. The circumference in millimeters corresponds to your US ring size. -
Measure the Diameter of a Ring You Already Own
Pick a ring that fits you well and measure the inner diameter (Ø) in millimeters. Then, refer to the size chart below to find the matching US size. -
