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 with 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
  • A ring that fits you

Step 1:

Make sure the ring you’re using fits the finger you plan to wear your new ring on.

Step 2:

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

Tip:

If your ring is a different shape and is not circular, measure the shortest distance across.

Using the diameter measurement you've just found, 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 usual ring size.
