Now that you’ve found the ring you love, you will need to determine the size of the ring to start the process. Below you will find a chart to help you.

If you will be measuring the circumference of your finger, you can use the chart below to help you determine the proper size. You can measure the circumference of your finger in either inches or millimeters, find it on the chart below and find the ring size from the US size column. Please be sure to measure the circumference of your finger several times and at different times of the day to ensure accuracy.
