How to Measure

You can measure a ring you already own by placing it on a ruler and measuring the inside diameter from edge to edge in millimeters.

You can also wrap a thin strip of paper or string around your finger, mark where it overlaps, then measure the length and compare it to the circumference column above.

Please note: Measurements are approximate and small differences may occur with home measuring methods.
