STEP 1: Measure your wrist with a flexible tape measure or a string just below your wrist bone. If you used a string, measure the exact length that it wrapped around your wrist.
STEP 2: Add about half an inch for the perfect fit. For a looser fit, feel free to add a little more.
FOR EX: If you measured your wrist at 6 inches, a comfortable fit would be 6.50 in.- 6.75 in. Keep in mind if you intend on wearing multiple bracelets on one wrist, it is best to go with a looser fit.
