Ring Guide
For the most accurate measurement, PRINT THIS PAGE.
Because different screens have different resolutions, the ring sizer cannot be used on-line. 

1. Cut a straight strip of paper 3 inches long and about 1/4 inch wide. (Make sure it's not much wider than 1/4 inch for most accurate sizing.)

2. Wrap this strip of paper around the finger that is to wear the ring. Then place a mark on the strip where it meets the end.

3. Place the mark on the strip of paper at "A" on the below Ring Guide that you have PRINTED.
The number at the end of the strip is your ring size.
Whole ring sizes fit ninety-nine out of a hundred people.
