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:

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.


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

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

Helpful sizing tips

When choosing a ring size:

Always choose the ring size of the largest finger you’ll be wearing the ring on.

Stackable rings:

For a more comfortable fit, consider selecting one size up from your normal ring size.

Wide shank rings:

This ring has a wider shank, so we recommend going one size larger than your normal ring size
