Use a piece of twine, wool, or cut a piece of narrow paper.
Put it around your wrist, where you usually wear your bracelet.

Where the rope joins the other end make a mark with a marker. Make sure the rope fits snugly around your wrist, don't tighten too much, but don't leave too much room either.

Finally, use a ruler to measure the piece of string from the end to the mark you made with the marker. This is the measurement you have to choose when you go to buy one of our bracelets. Based on this measurement, we will take care of making the model of bracelet you choose fit you perfectly.
