We want to make sure you have the best fit. To find out your ring size, you'll want to measure the finger on which you'll be wearing the ring.

Here is a simple method to calculate your size:

Wrap a piece of string or paper around the base of the finger that you want to measure. You'll want it to be snug, but not tight. Take a pen and mark on the string or paper where it overlaps to form a complete circle around your finger.

Run the string or paper along your ruler to measure it's length in mm. Lastly compare this measurement with the chart below to find the nearest measurement to yours. This will then be the size you require.
