Ring Size Guide

Getting the size right matters — especially for a ring you'll wear every day. Here are three ways to find yours. When in doubt, come and see us; sizing in person is always the most accurate.

Measure a ring you own
Take a ring that already fits the right finger and measure the inside diameter in millimetres. Match it to the chart below.
Use string or paper
Wrap a strip of paper or string around the base of your finger, mark where it overlaps, and measure the length in millimetres against the circumference column.
Come in and be sized
The most accurate option. Pop into the shop in Ashford and we will size you properly on a professional ring stick — no appointment needed.

Fingers swell slightly in heat and at the end of the day — measure when you're warm and relaxed for the truest fit. Our wedding bands can be made in half sizes too; just ask.
