For messuring your finger size we highly recommend to go to a jewelry shop and get your finger messured to ensure your accurate ring size, if not we recommend to messure a ring you already own which fits on the finger you want to use the new one. Please messure the inner diameter, placing a ruller in the middle of the circumference from the inner part of your ring. Please be as accurate as possible, then check that messurement in MILLIMETERS and compare it with the table below.
