RING SIZE GUIDE
For the most reliable result, measure a ring you already own that fits the right finger. Take its inner diameter or inner circumference in millimetres. No ring to hand? Wrap a strip of paper around your finger, mark where it overlaps, and measure the length.
This tool is a guide, not an exact measurement. Fingers change through the day and with the weather, often smaller when cold and larger when warm, so a reading here can easily be off by a size. For a size you can rely on, have your finger measured with a proper ring sizer at a jeweller before you order. We can’t guarantee fit from a measurement taken here.
