Find Your Ring Size

Use a ring that already fits or measure your finger to find the closest Stonex ring size.

Measure an existing ring

Choose a ring that fits the intended finger.
Measure its inside diameter across the widest point.
Match the diameter in millimetres to the chart.

Measure your finger

Wrap a non-stretch paper strip around the finger.
Mark where the ends meet.
Measure the length in millimetres.
Match it to the inside-circumference column.
Measure near the end of the day, and avoid unusually hot or cold fingers.

This chart helps estimate fit. US sizes are the closest equivalent, and sizing can vary slightly with a ring’s width and design.

Band width: Wider bands can feel tighter than fine bands. If you are between sizes, you may need the next available size.
