Measure My Finger

Instructions

1. Cut a thin strip of paper, ensure it’s not too wide.



2. 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.



3. Mark the spot where the paper meets and measure the distance with a ruler (mm).


Use the size chart to determine your ring size.
