• Measure Your Finger

    • To start, cut out a strip of paper that is approximately 3/4-inch wide and 4 inches long.

    • Use the paper to wrap around your finger. Then mark where the paper overlaps. That length in millimeters is the circumference of your finger.
    • To find your ring size, refer to our conversion chart.

    (If you have a big knuckle and a smaller finger below it,choose a size in the middle of these two measurements.)

  • Measure a Ring You Already Have

    • You can use a ruler to measure the inside diameter of a ring that already fits your finger well.

    Use our measurement-conversion chart to find your ring size by taking the diameter measurement in millimeters.
