Finger Sizing - Determining your ring size

The best way to do this is to go to your local jeweller and have them measure it for you. Ensure that the jeweller uses a ring sizer of similar width to the ring you are interested in. For example if you are looking for a 6mm wide ring and you have your finger sized with a 3mm wide sizer you may get the false impression of comfort and then when you buy the ring it will feel a bit tight. So if you are buying a narrow ring have your finger size measured with a narrow sizer, if you are buying a ring of 5mm or more have your finger size measured with a wide sizer.

Alternatively, all you need is a ruler and one of your rings that fit on the same finger you want to buy the new ring for. Measure the inside diameter of the ring in millimetres and then use this measurement when selecting finger size on the drop down box.

For example, the ring below has an inside diameter of 21mm.
