If you are unsure how to measure the size of your finger, please follow these simple steps:

  1. Get a piece of paper
  2. Cur the piece of paper so that it is about 1/2 inch in width.
  3. Wrap the paper around the finger you are buying a ring for and take note of where the start of the paper meets together. (Note: you will want to measure near the thickest part of your finger – like near the knuckle, as you need to be able to get the ring onto your finger).
  4. Use a ruler to measure the length of the paper from the start to where the paper met together when around your finger.
  5. The measurement you recive can then be compared with the measurements above.
  6. Now you have your ring size 🙂
