Ring Size Guide
Finding your ring size is simple. Use the guide below to measure at home — no jeweller visit required.
How to Measure Your Ring Size
Method 1: Use a Ring You Already Own
- Place an existing ring on a flat surface.
- Measure the inner diameter (straight across the inside) in millimetres.
- Match the measurement to the size chart below.
Method 2: Measure Your Finger
- Wrap a thin strip of paper or a piece of string around the base of your finger.
- Mark where the paper meets and measure the length in millimetres.
- This is your finger circumference — match it to the chart below.
Tip: Measure your finger at the end of the day when fingers are slightly larger. Avoid measuring when cold.
