Ring Size Chart

How to measure
Measure your finger
- Use a non-stretch strip of paper or a soft tape measure.
- Wrap it snugly around the finger where you will wear the ring, and mark where it joins.
- Lay it flat and measure the length to the mark in millimetres.
- Match that length to the inside circumference column below, not the diameter column.
Measure an existing ring
- Choose a ring that fits the intended finger comfortably.
- Measure straight across the widest part of the inside opening in millimetres. Do not include the metal.
- Match this measurement to the inside diameter column below.
If you are between sizes, or ordering a broad band on any ring other than the Eternal Dragon signets, confirm the fit with Chantel before ordering. Finger size can change with temperature and time of day, so for the best fit measure your finger at night, when fingers are at their largest. A professional ring fitting gives the most reliable result.
Eternal Dragon signet rings: please choose your normal ring size for a slim band. We will add a quarter of a US size when making your ring to allow for the wider band. You do not need to add this allowance yourself.

Size Chart
Our rings are sold in US sizes. Find your US size using the inside circumference or inside diameter in millimetres. UK and Hong Kong sizes are the nearest equivalents only, because these systems use different scales and published charts vary slightly. Your measurement in millimetres is the most reliable guide.
