Ring Sizing
It's important to know your ring size before ordering, use the chart below to find the right size. You can use an existing ring that is the right size to find the internal diameter or you can measure the circumference of your finger using a piece of string and measuring it.
Another option is to buy a ring sizer online, which costs about £2 and is definitely worth it as you will easily be able to find the ring size of any finger when you need it.
