Measuring Your Wrist for an Accurate Bracelet Size To find your perfect bracelet size, follow these steps: STEP 1: Measure your wrist with a flexible tape measurements or a strip of paper just below the wrist bone, where you would normally wear the bracelet. 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.
