Some people may already know your ring size you are by a letter, if so this is the easiest chart for you to use. You may also go into any jewellery store and have your correct ring size measured for your finger (via letter) which will ensure you have the correct size. If you are considering a wide band you may want to select the larger size for comfort on your finger.

Option 3: Printable Ring Sizer

  • Print this page. Make sure the printer is set to 100% or it will tell you the wrong size.
  • Cut out the ring size guide along the bottom of the guide and above the numbers so the piece of paper is approximately 1/4-1/2 inch width. Wrap the piece of paper around the finger in which the ring is to be placed with the numbers facing out.
  • Please make sure this is pulled snugly around your finger, so you see your correct size. If possible try to have someone help you do this.
  • The number that meets the end of the paper with the star is your ring size.
