It is very simple to determine the proper size for your bracelet. Directly measure the outer diameter of your wrist just below the tiny bump. The most convenient method for evaluating clothing is with an adjustable tape measure. You can also use a measuring tape and a ruler to figure out the size of your bracelet. Add several cm based on your preferred dressing comfort: 1 cm for a tight bracelet, 1.5 cm for a common bracelet, and 2 cm for a bigger bracelet.
