What is Ring size?

‘Ring size’ is a measurement that refers to the inside circumference of a ring. It’s important to know your correct ring size before buying a ring, otherwise it won’t fit properly.

Different countries use different standardised systems for denoting ring size.

On the right, there’s a chart with the 3 most common ring size systems used in UK, USA and internationally. For Australian sizes simply refer to the UK sizes, which are the same.

WHY USE A RING SIZER?

Ring size is one of those things we think we’ll always remember… but never actually do!

It is very important to find out the correct ring size whether the ring is for you or another person. This measurement enables us to provide you with a perfectly fitting ring. A ring that is so small you cannot get it on – or so big it falls off – can really ruin a big moment!

AN IMPORTANT NOTE ON RINGS

We are happy to accept returns and exchanges on rings between the sizes of J and Q. For rings outside of these sizes we cannot accept them back because they have been especially sized for your order.

HOW NOT TO MEASURE YOUR RING SIZE

We would advise you not to measure an existing ring at home with an ordinary ruler or tape measure. They won’t give you the high accuracy needed to size a ring properly. If you are buying the ring for someone else, you can take one of their rings to a local jeweller who will measure it with a ring sizer tool.

We’d also advise against the “string method” – measuring your finger with a piece of string, marking the string and then laying this against a tape measure. This comparison is always inaccurate because string is soft and stretchy, while a real ring is hard and keeps its shape.
