Find the Perfect Fit for Your Ring

  1. Find an existing ring that fits your finger comfortably.
  2. Measure the widest area inside the ring from the inner edge to the inner edge. Round off to the closest whole millimeter.
  3. Keep in mind that wider bands fit more snug and thinner bands fit more on the loose side.
