Ring Size Guide

 

Purchasing a ring can be a bit overwhelming, particularly if you’re unsure of your finger size. This guide provides useful tips to help you obtain an accurate measurement.

 

Measuring Finger Method

To find out your ring size, measure the inside diameter of an existing fitting ring with a ruler and check it against our chart below.

 

  1. Get a tape measure, some string or a strip of paper.
  2. Wrap it around the finger you want to measure and mark the place where it joins.
  3.  Lay the marked string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart below to match the measurement to the ring size.

If you don’t already have a ring – then why not try wrapping a piece of foil or paper around your finger to make a ring, measure the inside diameter with a ruler to check against our chart below.
