Ring Size Guide

Measure your finger

Take the strip of paper or string and wrap it around the base of your finger.Ensure it's snug but not too tight, as it needs to pass over your knuckle.

Mark the length

Make a clear mark on the paper or string with your pen where the end of the strip overlaps itself.

 Find your size

Unroll the paper or string and lay it flat against a ruler. Measure the length from the start to the mark in millimeters (mm).Use this measurement to find your corresponding ring size on a printable or online ring size chart.
