STEP 1: Measure your wrist with a flexible tape measurements or a strip of paper just below the wrist bone.

STEP 2: If you are using a plain strip of paper, mark your size with a pen or pencil then use a ruler to measure the length. That would be your wrist size.

STEP 3: I recommend sizing up 1/2 to 1 inch depending on how snug you like the bracelet to fit.
