Ring Size Chart
How to measure your ring size
To determine your size, we strongly advise that you measure the size of your finger rather than the size of your ring.
1. Using a length of string or ribbon, wrap it around the base of your finger. To ensure the ring fits comfortably, we suggest measuring your knuckle as well. We recommend selecting a size that will slide on and off your finger easily.
2. With a pen, mark the point on the string where the ends meet.
3. Measure the string in millimeters with a ruler.
4. Choose the closest measurement to the chart on the right to identify your ring size.
TIPS
- The string or ribbon must fit snugly to produce an accurate size.
- Finger size can change depending on the time of day and weather; for the most accurate measurement, measure your finger at different times of the day, and on different days to compare.
- Avoid measuring your fingers when they are cold or wet, as they will be at their smallest.
Bracelet Size Chart
To determine your size, we strongly advise that you measure the size of your wrist rather than the size of your bracelet.
1. Use a tape measure. Wrap the tape measure around the wrist on which you plan to wear your Cartier bracelet. Make a note of the number at the point where the tape meets the 0. To ensure the bracelet fits comfortably, add 1.5 cm.
2. You can then add or subtract centimeters according to whether you prefer a loose, exact or tight fit.
3. Choose the closest measurement to the chart on the right to identify your wrist size.
