How to work out your own ring size

Tuesday, 30 June 2015  |  Anne

 

Don’t know what size ring you need? As with most other things, rings are measured differently depending which country you live in. I provide UK and USA sized in all my ring descriptions. There is a different sizing system used in Europe. You can but ring sizing gauges but if you don’t have one handy you can estimate your ring size. Take a piece of string and wrap it around the widest part of your finger (possibly the knuckle joint?) – you can now measure the string in millimetres and use the chart below.

Warning: If you have chunky knuckles  - the ring will slip round your finger once it is on. However if you buy a size which will stay put it wont go over your fingers

 

UK SIZE A B C D E F G H I J K L M
USA SIZE 0.5 1 1.5 2 2.5 3 3.25 3.75 4.25 4.75 5 5.5 6
SIZE MM 37.8 39 40.2 41.4 42.6 43.8 45 46.2 47.4 48.5 49.1 50.3 52.1
