Ring Size Guide
Ring Size Guide
Finding your perfect fit is simple. Rubielle London rings follow standard UK sizing, from F to Z.
How to measure at home
Wrap a thin strip of paper or a piece of thread snugly around the base of your finger, mark where it overlaps, and measure the length in millimetres against a ruler. That measurement is your inside circumference — find it in the table below. For the most accurate result, measure at the end of the day, when your fingers are at their natural fullest, and avoid measuring when your hands are very cold.

Between two sizes?
We recommend choosing the larger of the two, particularly for wider bands, which wear slightly more snugly.
