Measurement Guide
To determine the correct ring size for you, we recommend measuring your finger rather than using another ring as a reference.
Use a piece of string or ribbon and wrap it around the base of your finger.
Mark the point where the ends meet with a pen.
Measure the length of the string in millimeters (recommended) or inches using a ruler.
Refer to the size chart at the bottom of this page. Use the number you measured (under the column titled “Finger Circumference in Millimeters”) to find the corresponding size according to Cartier's sizing chart.
Tips
Make sure the size you choose allows enough room for the ring to comfortably slide over your knuckle.
