Measure your finger
Wrap a strip of paper around your finger where you’d like your ring to be.
Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit.
Mark the spot where the paper meets and measure the distance with a ruler (mm).
Use the below chart to determine your ring size.
