How to measure for correct ring size

1. Find a strip of paper no wider than 1/2".

2. Wrap it around the base of the appropriate finger.

3. Use a pen to mark the point on the paper where it overlaps
forming a complete circle.

4. With a ruler, measure the length from the starting end of the
paper to the pen mark.

5. Use this measurement and the chart to the right to determine your ring size.

Here are some tips to make your ring size measurement more accurate:

After sliding the paper ring on, make sure it slides off fairly easily over the knuckle.

Don't measure cold fingers. This is when fingers are smallest. For the most accurate reading, measure the finger at the end of the day when  the finger is largest.
