Another way to find the perfect size is to use a ring that fits the finger you wanna wear your new ring on as a reference point. This method also works when secretly trying to find the right ring size to surprise a loved one.
Start by choosing which finger you’d like your new ring to sit on, then select an existing ring that already fits comfortably on it. Measure the inner diameter of the ring with a ruler. Use the conversion table below to determine the corresponding ring size. For example, a diameter of 18.45 mm corresponds to ring size 18. If your existing ring falls between two sizes, we advise sizing up.
