How to Measure Your Ring Size at Home
Method 1: Use a string or paper strip to wrap around your finger. Mark the point where it overlaps and measure the length (in mm).
Method 2: Measure the internal diameter of a ring you already own using a ruler or caliper. Match this with our size chart.
For the most accurate results, measure your finger at the end of the day when it’s at its largest. Avoid measuring when hands are cold.
