The most accurate method of finding the proper ring size for your finger would be to visit a local jewelry store and ask for a sizing. They usually offer this service free of charge.

Another method which you can try at home is using a string, a tape measure and the ring size chart listed below.

1. Find a piece of string.
2. Wrap it around the base of your finger.
3. Use a pen to mark the point on the string where it overlaps to form a complete circle.
4. With a ruler, measure the length from the starting end of the string to the pen mark.
5. Use the measurement and the chart below to determine your ring size.
