If you are unsure of the ring size for the intended finger, use our printable ring sizer or request a complimentary plastic ring sizer below. For further assistance, contact a diamond and jewelry expert at 866-737-0754.

For international customers, please use our International ring size conversion chart to determine the standard size that corresponds to your international ring size.

Printable Ring Size Chart


In order to obtain an accurate ring size, follow the paper size validation instructions on the printable ring sizer. To ensure an accurate measurement, gauge your finger toward the end of the day when it is slightly larger. Your fingers are smaller when they are cold, so be sure that your hands are warm when measuring. To keep the ring a surprise, follow the instructions on the printable ring sizer using your partner's ring that is properly sized for the intended finger.

International Ring Size Chart Conversion


This chart includes ring size conversions from the US/Canadian standard ring size to the ring sizes used in the United Kingdom, France, Germany, Japan, and Switzerland.
