MEASURING GUIDE

To determine your ring size, we strongly advise that you measure the size of your finger rather than the size of another 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.
2. With a pen, mark the point on the string where the end meets.
3. Measure the string in millimeters (recommended) or inches with a ruler.
4. Use size chart at the bottom of this page. Refer the size you found in the 1st column (named “finger circumference in MM”) to then find the right size by Cartier collection.

TIPS

• Measure your finger at the end of the day.
• Do not measure your finger when it is hot or cold.
• Remember that the two hands differ slightly in size.
• Make sure that the chosen size leaves enough room for the ring to pass easily along the entire length of the finger.
