How to find your ring size

Use the dropdown menus below to help find your circumference or diameter measurement. Next, use the chart to see which ring size corresponds to your measurement and find your perfect size.

Diameter is the measurement across the inner width of a ring, going from one side to the other.
You'll need:
  • Tape measure or ruler
  • Existing ring that fits well

Step 1:

Ensure that the ring you use fits the finger on which you plan to wear your new ring.

Step 2:

Use your ruler or tape measure to measure the widest points inside the ring from edge to edge.

Tip:

If your ring has a different shape (not circular), measure the shortest distance across.

Use the diameter measurement you've just found, and consult the chart to see which ring size corresponds with your measurement.

Ring stacking:

For a more comfortable fit when stacking rings on top of each other, consider selecting one size up from your normal ring size.
