The following ring size guide is perfect for women or for men looking to purchase a ring online, that are unsure of their exact size. If you have an existing ring that is a comfortable fit on your finger and doesn't slip off your knuckle, then that would be perfect to find your ring size.

How to measure ring size:

Step 1 - Print out the below ring size chart at 100% and make sure the line in the image measures exactly 135mm.
