Sizing

Don't know your ring size? You can easily find out with a ruler and thin strip of paper.

Cut a thin strip of paper.
Wrap the paper around your finger. Make sure the paper is below the joint of your finger and close to your knuckle.
Mark the spot where the paper meets and measures the distance with your ruler.
The chart below will tell you your ring size. Some rings also come in half sizes (will fall somewhere in between the whole sizes).
