How to Know your ring size

If you would like further assistance, you can visit Cartier boutiques or contact the Client Relations Centre. To determine your ring size by yourself, we strongly advise that you measure the size of your finger. There are tips for how to know your Cartier ring size.

Cartier Wedding Ring

Measure your finger at the end of the day. Do not measure your finger when it is too cold or wet.
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.
Measure the circumference of your finger in mm. This measurement corresponds to the above size chart.
Remember that the two hands differ slightly in size; a ring worn on a finger of the left hand will not be a perfect fit for the same finger on the right hand. Make sure that the chosen size leaves enough room for the ring to pass easily along the entire length of the finger.

Please note that the style of the ring will also affect the choice of size. If you choose a ring to be a gift, borrow one of the recipient’s rings with a similar width as the ring you would like to purchase and choose the same size in store. If your ring appears between two sizes, we recommend selecting the larger size.
