Ring sizing
If you know your ring size in other than UK sizing, you can use the table below to convert, and make sense of our listings.
If you do not know your finger size, either measure your finger - or a ring you already have which fits as you would like - and again use the table below … or you could nip in to a jewellers and ask them to measure it for you (and just pretend to be interested their biggest rocks!).
When measuring your finger please note:
- it is best to measure at the end of the day as this is when your fingers are at their biggest
- do not measure when your hands are cold
- a ring should be a snug but comfortable fit that will slip over your finger joints but won’t just fall off.
