Determining Your Ring Size
Find Your Ring Size – Option 1
Measure the Inside Diameter
Place a ring that fits you well on a ruler. Measure the inside of the ring in millimeters or inches or milimeters, then match it to the corresponding size in the chart below.
Helpful Tip:
Wider bands may fit more snugly, so we recommend choosing half a size larger for a more comfortable fit.
Find Your Ring Size – Option 2
Measure an Existing Ring
Wrap a thin strip of paper or string around the base of your finger and mark where it overlaps. Measure the length against a ruler in inches and find your match in the chart below.
Pro Tip: Your fingers are largest at the end of the day. Make sure the loop can slide over your knuckle!
