Find your ring size

Wrap a thin strip of paper snugly around the base of the finger, mark where it overlaps, and measure the length in millimeters. Match it to the circumference column.
Have a ring that fits? Measure its inside diameter and match it to the diameter column.
Measure at the end of the day, when fingers are largest. Between two sizes, or a band over 6mm wide? Choose the larger size.
