Sizing for Bracelets
Measure the circumference (distance around) or diameter ( distance across) of your wrist where you'd like the bracelet to sit comfortably with a measuring tape or piece of string and a ruler, and add about an inch to the measurement. Most cuffs adjust. In the case of a bracelet with no opening or closure, measure the circumferences around your knuckles and wrist.
