Finding your correct ring size is simple! Follow the steps below to measure your finger accurately and use our size chart for the perfect fit.


How Do I Find My Ring Size?

If you're unsure of your ring size, don’t worry — here are two easy methods to help you measure it accurately.


OPTION A: Measure Your Finger

Step-by-step guide:

  1. Cut a thin strip of paper about ¾ inch wide and 4 inches long.

  2. Wrap the paper around the base of your finger.

  3. Mark the point where the paper overlaps.

  4. Measure the length of the paper in millimeters (mm).

    • This is the circumference of your finger.

  5. Use our conversion chart (below) to find your ring size.

Important Tip:

If the size of your finger below the knuckle is very different from your knuckle size, measure both and pick a size in between for the best fit.


OPTION B: Measure an Existing Ring

  1. Choose a ring that fits the finger you plan to wear the new ring on.

  2. Measure the inside diameter (in mm) of the ring.

  3. Match the measurement to our ring size chart below.
