How To Find Your Ring Size
1. Wrap a piece of string or paper around your finger. Make sure to account for the size of your knuckle.
2. With a pen or sharpie, mark the 2 spots on the string/paper that overlap or meet.
3. Unwrap the string/paper and lay flat on a surface. Using a ruler, measure the distance (in millimeters) between the two dots.
4. Find your Inside Circumference in the chart below and convert it into a standard US/UK/AUS ring size.
