Ring Sizing

As an online jewellery store, we understand how you might feel intimidated when purchasing your new ring given that you can’t physically try it on.

In South Africa, the UK and Australia, ring sizing works according to alphabetic letters. However, in America, Europe and rest of world, ring sizing is done numerically.

Collective & Co. sells according to numeric sizing. We also do not currently sell in half sizes and recommend that, if you are between sizes, you size down to the nearest full size. For example, if you are a 7.5, size down to a 7.

The best way to get accurately sized would be to visit your local jewellery store and establish what size you are in terms of alphabetic letter and ring diameter. 

Below is a summary of how you can convert your ring size into a numeric size:


 Collective & Co. Sizing





Size 5 15.7  J1/2 X- Small
Size 6 16.5 L1/2 Small
Size 7 17.3 N1/2 Medium
Size 8 18.1 P/12  Large


As an alternative option, we suggest using our ring sizing guide that can be found here.

When executed properly this method can determine your correct ring size fairly accurately. 

 We hope that selecting the correct ring size with the help of this guide will make the process a little less daunting!
