Ring sizes are measured on an ascending alphabetical scale, with the first few letters of the alphabet corresponding to the smallest sizes.
Any quality jewellers should be able to tell you your ring size free of charge, but you can also follow our home ring sizing guide here to find out your size.
If you are still unsure which size to choose, order a standard size (M for women, U for men) and we will be happy to offer a free resize if necessary. Please contact us for any further advice.
