Ring Size Chart Guide
All Proud Diamond are specified in standard US sizes. Here is a ring size chart that includes both inch and centimeter measurements, which you may use as a reference.
Tips and tricks
- Each finger may have slight differences. Make sure you measure the right finger on the correct hand!
- Measure your finger at normal body temperature. Finger size can become different when hot or cold.
- Choose a time towards the end of the day when your fingers are at their largest.
- If your knuckle adds a twist to the equation, measure twice and choose the middle ground. Your ring should glide over the knuckle without being too loose or sliding out of place.
- When in doubt, go for the gold standard! The average ring size for women is 6 to 7, and the average for men is 9 to 10.
