How to measure your finger and determine your ring size.

There are  a few easy ways to determine your ring size in the comfort of your home. Here are two easy options you can use to find a ring size that will fit you best:

Option 1: Measure your finger


  1. Get a non-stretchy string or paper about 6" long.
  2. Wrap around the base of your finger. It has to fit snug, but not too tight.
  3. Mark the point on the string/paper where it overlaps forming a circle.
  4. Measure the string/paper up to that point in Millimeters.

Option 2: Measure a ring you already own

If you have a ring that already fits you well, you can use a ruler to measure the interior diameter of a ring.



  1. Take a ruler and measure straight across the interior of the ring from edge to edge as shown the image from above.
  2. Take the diameter measurement in millimeters, and then use our measurement-conversion chart below to find your ring size.
