Ring Size Guide
How To Measure Your Finger
The best way to find your ring size is to take a piece of string or a strip of paper and wrap it tightly around your finger. Mark it where it meets and then measure the length. That length is the circumference of your finger, you can then match that up with the 'Inner Circumference' column in the chart below. We recommend using the US size as it's a bit more straightforward and easier to remember than the letter system we use here in Australia.
