Use a tape measure. Wrap the tape measure around the wrist on which you plan to wear your bracelet.
Note the number at the point where the tape meets the 0 or simply put a mark on it.
Remember to add 1.5cm to ensure the bracelet fits comfortably. You can add or subtract space according to whether you prefer a loose, exact or tight fit.
