Ways to find your LILY & ROO ring size:

  1. Measure the inside diameter of a ring you already own. (Check the table above in the ‘Inner Diameter of Ring (mm)” column to find your ring size.
  2. Download the Ring Sizer app if you have a smart phone, using an existing ring.
  3. Measure the circumference of your finger.
    • Measure your finger by wrapping around it with measuring tape. If you do not have tape you can use string/ floss and measure against a ruler.
    • Check the table above in the “Finger Circumference (mm)” column to find your ring size.
