How to Measure Your Ring Size
◉ String / Paper Method
Wrap a thin strip of paper or string around your finger. Mark where it overlaps. Measure the length in mm — this is your circumference. Use the chart above to find your size.
◈ Existing Ring Method
Place an existing ring on a ruler and measure the inner diameter in mm. Match the diameter to the chart above to find your size.
1
Measure at end of day when fingers are at their largest
2
Measure the finger you plan to wear the ring on — sizes can differ between fingers
3
If between two sizes, choose the larger size
4
For wide bands, go one size up as they fit tighter
