Ring Sizer

Size Guide

What ring size am I?

UK ring sizes use a lettered scale from A–Z and are measured by the inside circumference and diameter of a ring. Use our size chart below to measure yourself or you can request our ring sizer to use at home here.

How do I measure my ring size at home? 

Use a piece of string that's cut to around 6 inches long to wrap around the fleshy part at the base of your finger, then mark the string with a pen at the point it connects.

Top tip: the string should be snug but not tight and don’t measure it when you’re cold as your finger width will be about half a size smaller. 

Measure the length from string end to pen mark with a ruler to get your circumference and match this to your ring size on the ring sizer chart below.
