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.
