How to measure at home
- Wrap a strip of paper or string around the base of your finger.
- Mark where the ends meet, then measure the length in millimeters — that's your circumference.
- Match it to the closest size in the chart above.
- Measure at the end of the day, when fingers are at their largest, for the most accurate fit.
