How do I know my ring size?
Download this file, and print it on a blank piece of white paper.
Before you begin, make sure the scaling is accurate by measuring the 20 centimeter key at the bottom of the page.
Place an existing ring on one of the circles on the top part of the printed paper.
Make sure to align your chosen ring with the INSIDE edge of one of the circles.
If the ring is a little bit smaller or larger than the circle, you are a half size.
