How to Measure Your Ring Size
1
Wrap a thin strip of paper or string around your finger — not too tight.
2
Mark the point where the ends meet with a pen.
3
Lay it flat against a ruler and measure the length in millimetres.
4
Enter that measurement into the Circumference (mm) box below.
💡 Measure in the evening when fingers are at their largest. If between sizes, choose the larger.
