Size Guide
Choosing your ring size
Our ring sizes use UK letters. The sizes offered for each design are shown in its Size selector. Check those options before ordering; this guide does not mean that every design is available in every size.
A comfortable ring should feel secure without pinching and slide over your knuckle with gentle resistance. Measure the finger and hand you will wear it on several times during the day, when your hands are neither very cold nor very warm.
Measure your finger
- Wrap a narrow strip of paper around the base of your finger without pulling it tight.
- Mark where the paper overlaps, then lay it flat and measure to the mark in millimetres. This is the circumference, not the diameter.
- Repeat the measurement and compare it with the approximate guide below.
Paper measurements are a starting point. A jeweller's ring sizer gives a more reliable fit, especially for wider bands or larger knuckles. If you are between sizes or unsure, contact customercare@charlottereedtz.com before ordering. Do not assume that a half size or a size outside the selector can be supplied.

Using a ring sizer
You can ask a local jeweller to measure your finger or use a ring sizer at home. Ring sizers are also available from Amazon.
