Print the page in the link below, and follow the instructions in order to measure an already existing ring you may have at home in order to find your YSSO size.

1. Print the page ensuring that scaling is set to none (100%) in the print dialog box.

2. Position your own ring over the circles below, liming the inside of the ring with the circles that matches the size most optimally. If your size is between two sizes, or if you are unsure of your size, opt for the largest of the two.
