Ring Size Guide
How to Measure Your Ring Size at Home
You can measure your ring size in two simple ways:
Using a Ring You Already Own
Measure the internal diameter of a ring that fits you well.
Match the measurement to our size chart below.
Using a Piece of String or Paper
Wrap a piece of string (or a thin strip of paper) around the base of your finger.
Mark where the ends meet, then measure the length in millimetres.
Use the measurement to find your size in our chart.
Tip: Measure your finger at the end of the day when it’s slightly larger. Avoid measuring when your hands are cold.
