How To Measure with your own ring 

  1. Choose a ring you own that fits the finger you want to order for.
  2. Place your ring over the sizing circles to find the best match.
  3. The sizing circle should fit the inside circle of your ring.
  4. If your ring is between two size circles, order a half (.5) size up from your closest fit.
  5. Please measure the diameter of the circles below to confirm the measurement meets the diameter sizing in the table above.

  

For best results print this page on US letter and ensure page scaling is set to NONE. Once printed, use a ruler to measure the lines below to be sure it has printed to scale at 2 inches or 20mm.
