The best method of getting an accurate ring size measurement is to use a Vernier Caliper. A Venire Caliper can take the exact measurements of a ring. You can measure the inside diameter of a ring you already own (that fits perfectly on the finger you intend to wear it) using the internal jaws of the Vernier Caliper.
