Measure the internal diamter of the ring (in mm). Ensure your ruler stars at the 0mm mark.
Use the measurement chart to match the size of your ring to the closest size in mm. The interior of the ring should align with the outer edge of the circle.
Measure Your Finger
Cut a thin strip of paper, ensure it’s not too wide.
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).
