Circumference: The full outside measurement around your chosen finger.
Find your size in 3 easy steps:
1. Wrap a strip of paper around your finger, allowing for the size of your knuckle.
2. With a pen, mark the point on the paper where the two ends meet.
3. Measure the paper against the ruler in mm and compare it to the circumference in the above chart.
