To determine your wrist size, measure your wrist with a flexible, soft tape measure just below the bone. This is your actual wrist size. Please do not add to this measurement. We will adjust the size to ensure a proper fit. It is very important to have a proper fit since this will ensure that the toggle clasp is secure. The average adult wrist is 6 1/4 inches. If the bracelet is a gift and you don’t know the wrist size, indicate what you think it may be. We will be glad to resize any bracelet at no charge if it does not fit properly
