How to Measure Your Ring Size
- Using an existing ring: Measure the inner diameter in mm and match it to the chart above.
- Using a strip of paper: Wrap a thin strip of paper around the base of your finger, mark where it overlaps, measure the length in mm — this is your circumference. Divide by 3.14 to get your diameter.
- Tip: Measure at the end of the day when fingers are at their largest.
