METHOD # 1
Measuring Your Wrist:
Use a flexible measuring tape, a strip of paper, or a piece of string.
Wrap it snugly around your wrist just below the wrist bone
(where you would normally wear a bracelet). Mark the point where it overlaps
and measure the length in centimeters or inches. Add 1.5 to 2 cm
(about ½ to ¾ inch) to your wrist measurement for a comfortable fit.
This total length is your bracelet size.
