Ring Sizing Guide

RING SIZING

Ring sizing is not completely straightforward and can be affected by things like time of day, weather, being more active, body changes with age. So we do suggest trying your size on a few different days to get an average.

The simplest way to work out your ring size is to measure a ring you already own.

To do this you just take a ruler and measure straight across the inside of the ring from inside edge to edge. Take the diameter measurement in inches or mm, and then use our measurement-conversion chart to find your ring size.

If you don't have a ring of the same size:

Take a piece of string or paper and wrap it around the base of the finger to measure.
Use a pen to mark the point on the string or paper where it overlaps.
Take a ruler and measure the length of the string or paper from the starting end, to the end you marked with the pen.
Use this measurement and compare it against the chart below to determine your ring size.
