1. Use a flexible tape measure or string to find the ideal size.
Wrap the tape measure or string around the widest part of your wrist, usually near the wrist joint. If you're using string, use a pen to mark where the ends meet. If you're wearing multiple bracelets, measure where you'll wear them on your arm.

2. Lay the cord flat and measure the length with a ruler, in inches or millimeters. Compare your measurement to the size chart provided to find your bracelet size. If your measurement is in between two options, choose the larger size for a more comfortable fit.
