Ring Size Guide
Ring Size Guide
Good news first
Our rings are open, adjustable bands. They're designed to be eased gently to fit, and they comfortably cover roughly UK sizes J to Q — which is most people.
If you're within that range, you can order without measuring anything.
How to adjust
Ease the band open or closed with light, steady pressure between your fingers. Go slowly, adjust as little as you need, and avoid repeated bending — like any metal, it will weaken if worked back and forth many times.
If you'd like to check your size
With a strip of paper:
- Cut a strip of paper about 5mm wide
- Wrap it around the base of the finger, snug but not tight
- Mark where the paper overlaps
- Lay it flat and measure to the mark in millimetres — that's your circumference
With a ring you already own: measure the inside diameter in millimetres, straight across.

Tips
- Fingers swell in heat and late in the day — measure in the evening for the truest fit
- Your dominant hand is usually half a size larger
- If you're between sizes, go up
