If you're struggling to size your finger for a ring at home you can purchase one of our ring sizers. The multisizer works like a belt, forming a ring and then placing over the finger, adjust to give a comfortable fit. Then simply read off the indicated size. You want the ring to slip on, but wriggle off, so it's not too loose. Measure your finger at normal temperature, not too hot, as your finger may be swollen, and not too cold.
This multisizer is marked with British Ring Sizes A-Z
