If you're not sure, here's a simple way to find your ring size;

* Step 1: Cut a strip of paper or use piece of non-stretchy string/ribbon 
* Step 2: Wrap this around the finger you want the ring for. Make sure the fit is snug but not too tight or too loose.
* Step 3: Mark the point where it completes a circle round your finger. 
* Step 4: Measure the length of the marked paper or your piece of string and find the closest equivalent length on the inside circumference part of the chart below:



Or if you already have rings that fit comfortably you can measure them across the middle part of the ring and find the closet equivalent size on this chart.
