Oh ring finger sizing! A tricky art! Here's the best method we've determined along with a helpful little illustration.
To determine your correct finger size, you need to first figure out what width of ring you’d like as this directly affects the size needed. As the width increases the size needs to increase a little as well.
Almost any thickness/width/finger size is possible - including ¼ finger sizes but with etchings usually 3mm is as narrow as we like to go.
The best thing to do is to try on rings with different widths to find which one you like the look and feel of. When you find one that is the right size and width, measure the size - to the edge of the ring.
Another way to find the right width is to cut pieces of card in different widths and wrap them around your finger.
If you are using an existing ring to find a size, the inside diameter is what you're looking for, small amounts make a big difference so a measurement to the nearest ¼ of a millimetre is needed.

Titanium cannot be resized so it is very important to get the size right first time. If the size needs to be adjusted any more than 1/4 of a size up a new ring will need to be purchased.
