1. Measure your wrist just below the wrist bone, where one would normally wear a bracelet, with a flexible measuring tape, or a strip of paper.
2. If you are using a plain strip of paper, then measure that item with a ruler to determine your wrist size.
3. Add 1/4 inch to 1 inch to your wrist size, depending on whether you would like a snug, comfort, or loose fit.
