Ring Sizing 101
Rings designed for everyday comfort. Start here for simple sizing and styling.
Getting the right fit is easier than it sounds. All you need is an existing ring or a strip of paper and a ruler.
We'll help you translate your measurement into the size that feels just right.
Measure Your Finger
Step 1
Pick the finger you'll be adding a ring to.
Step 2
Cut a strip of paper—thin enough to lie flat against your skin.
Step 3
Place it at the base of the finger and wrap it around the spot where you'd like your ring to sit.
Step 4
Pull it snug to make sure you get the best fit.
Step 5
Mark the point where the paper meets.
Step 6
Measure the length using a ruler, in millimeters.
Step 7
Repeat as necessary. It's always best to double (or triple) check.
Step 8
Then, match your measurement to the chart below. If you fall between ring sizes, we suggest measuring up for comfort.
Measure an Existing Ring
Step 1
First, choose a ring from your collection that fits your finger well.
Step 2
Measure straight across the inside of your ring using measuring tape (in millimeters).
Step 3
Then, match your measurement to the chart below.
