Ring Sizing & Measuring

Many people don't know their ring size, so we're here to help you figure that out.

  • Take a piece of string or strip of paper and wrap it around the base of the finger you would like to wear a ring on. Then simply measure the string or paper and check that against the "inside circumference" in the below table to find out your size. We use US size on our website.
  • You can also measure the inside diameter of a already existing ring and use the table to find your perfect fit!
