RING SIZE GUIDE

Measure My Own Ring

Instructions:

  1. Use a ring that fits the desired finger.
  2. Measure the internal diameter of the ring (in mm). Ensure your ruler starts at the 0mm mark.

Measure My Finger

  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).
  4. If you're like me and have particularly prominent second knuckles on your fingers, please use the second knuckle as your reference point.

Use the size chart to determine your ring size.
