Find your ring size

 

 

Having your finger sized by a professional jeweller is the most accurate way of finding your ring size. However if you do need to do this at home, this ring sizing chart might come in handy!

Find a ring that fits on the finger you are buying for and measure its inner diameter (check out the diagram on the right). All ring sizes in the shop are presented in US sizing.

If you already know your ring size, this chart should help you convert it to US sizing if necessary.
