Find your ring size
Three simple methods to determine the ideal size.
1
Measure the diameter
Place a ring you already wear on a ruler and measure the inside diameter in millimeters.
2
Finger circumference
Wrap a string or paper strip around your finger and measure the resulting length in mm.

Tip: Measure your finger at the end of the day when your fingers are slightly larger. Avoid measuring after physical exertion or in very cold weather. If in doubt between two sizes, choose the larger one.
