How to measure at home
Method 1: Use a ring you already own
- Choose a ring that fits the finger you want to wear your new ring on.
- Place it on a ruler and measure the inside diameter, from one inner edge to the other, in millimetres.
- Find the closest diameter in the chart above.
Method 2: Measure your finger
- Wrap a thin strip of paper or string around the base of your finger.
- Mark the point where the ends meet.
- Lay it flat and measure the length in millimetres.
- Find the closest circumference in the chart above.
Tips for the perfect fit
- Measure at the end of the day, when your fingers are at their largest.
- Avoid measuring when your hands are cold, as fingers shrink slightly.
- If you are between two sizes, choose the larger one.
- Wide band rings fit more snugly, so consider going half a size up.
