How to measure your size
With a string or a strip of paper
Wrap a string around the base of your finger, mark where it meets, then measure the length in <strong>millimetres</strong>. That measurement is your French size (e.g. 54 mm = size 54).
Our jeweller's tips
- Measure your finger at the <strong>end of the day</strong>, when it is at its natural size.
- Avoid measuring when your hands are <strong>too cold or too warm</strong>.
- A wide band may require <strong>half a size up</strong>.
- The ring should pass the knuckle with slight resistance, without forcing.
