How do I find my ring size?
The easiest way to find your ring size is to measure the inside diameter of a ring you already wear comfortably on the same finger. Place the ring on a ruler and measure straight across the centre — then match the measurement to our size chart. If you don’t have a ring to compare, you can wrap a thin strip of paper around your finger, mark where it overlaps, and measure the length. Make sure you measure at the end of the day when your hands are warm, as fingers can change size slightly throughout the day. For a more precise measurement, we recommend visiting a local jeweller who can size your finger professionally.
