Ring Size Guide
Ring Size Guide
Not sure what size to order? Here’s how to find your perfect fit before you buy.
Method 1: Measure an Existing Ring
Take a ring that already fits the intended finger. Measure the inside diameter in millimeters using a ruler, then match it to the chart below.
Method 2: Measure Your Finger
Wrap a strip of paper or string around the base of your finger, mark where it overlaps, then measure the length in millimeters and match it to the “Circumference” column below.

Tips for an Accurate Fit
- Measure at the end of the day, when fingers are at their largest.
- Wider bands fit more snugly than thin bands — consider going up half a size for statement or signet rings.
- If you’re between two sizes, we recommend sizing up.
- Ordering as a surprise gift? A well-worn ring borrowed briefly for measurement is the most reliable method.
