How to measure - Circumference (C)

Wrap a strip of paper around one’s desired finger, where one would like the ring to be.
Make sure the paper is pulled snug to one’s finger — this would be the tightness of your ring
Mark the spot where the paper meets and measure the distance with a ruler (mm).
Use the chart below to determine your ring size.

If one already has an ideal ring
