Simply cut a piece of string or yarn and measure the circumference of the finger you want to size (distance around your finger). Next, measure the string and reference the chart below to determine the correct size.

3 RING SIZE MEASUREMENT (mm)

OPTION #2: MEASURE AN EXISTING RING

If there is a ring that you currently have which fits well, just measure the inside from side to side. This is called the diameter of the ring. Using a standard ruler with millimeters (mm), measure the inside of the ring from one side to the other (important to only measure the empty distance between the inner walls of the ring). Using the ring size conversion chart below, determine the correct ring size.
