Ring Size Guide

Why ring size matters

Wearing your perfect ring should feel as effortless as a walk along the Cornish Coast and that starts with getting the right fit.

A ring that's too tight may feel uncomfortable, while one that's too loose could slip off and get lost. That’s why measuring and choosing the correct ring size is so important.

How to measure ring size at home

Option 1: Use a Ring You Already Own

  1. Pick a ring that fits the intended finger well.
  2. Measure the inside diameter (straight across the center) in millimeters.
  3. Compare it to our ring size chart (e.g., 16.5 mm = UK size L 1/2).

Option 2: Use a Strip of Paper or String

  1. Cut a thin strip of paper or use string.
  2. Wrap it around the base of the finger – not too tight or too loose.
  3. Mark where the ends meet.
  4. Measure this length in millimeters (this is the circumference).
  5. Use a size chart to convert circumference to ring size (e.g., 50 mm = UK size K).

Tips:

  • Measure at the end of the day (fingers swell slightly during the day).
  • Avoid measuring cold fingers (they shrink a bit).
  • If you're between sizes, go for the half-size inbetween.
