Use a thin ribbon to measure your ring size. Wrap it around your finger where you are wearing the ring. Cut off or mark where the ribbon wraps around your finger, measure the exact length of the ribbon you get with a ruler and convert the result into mm. Then divide the length of the ribbon in mm by the value 3.14. As a result, you get the diameter of the ring.
