How to find your ring size
To avoid having to return your ring for a new size, we highly recommend that you download this free app (iOS) to work out your ring size before ordering. Alternatively, you can measure at home using a ring you already own, or a piece of string or paper.

Using a ring you own: place it on a ruler and measure straight across the inside, edge to edge, in millimetres. Match it to the Internal Diameter column below.
Using string or paper: wrap it around the base of your finger, mark where it meets, then measure the length in millimetres. Match it to the Circumference column below.
Réalta rings come in whole US sizes. If you are between two sizes, we recommend choosing the larger one. Each US size sits between two UK letters, so if you are either letter, choose that US size.
