How do I convert my ring size to another sizing system?

Converting your ring size is simple once you know which sizing system you're using. The UK uses letters (A–Z), the US uses numbers, and EU sizes are based on the ring's inner circumference in millimetres.

The easiest way to convert your size is by using a ring size conversion chart. Simply find your current size and match it to the equivalent size in the other system. For example, a UK size M is approximately a US size 6¼ and an EU size 52.

If you're unsure of your size, measure your finger or an existing ring first, then use a conversion chart to find the closest match. When shopping internationally, always double-check the retailer's sizing guide, as slight variations can sometimes occur between brands.
