Ring size guide
Measure at home in a minute, or let us post you a free ring sizer. Not sure? Choose your best guess, as most of our rings can be resized afterwards.
How to measure
- Wrap a strip of paper or thread around the base of the finger, snug but able to slide over the knuckle.
- Mark where it overlaps, lay it flat and measure the length in millimetres.
- Enter it below. Measure at the end of the day, when fingers are slightly larger, and avoid very cold days.
