Cut out an even strip of paper, string or our JB Sizer.

Wrap the paper or string around the base of your finger, just below the knuckle. While doing this, take into account that the ring will need to slide over your knuckle, as many of us have knuckles that are wider than the base of our finger. Our rings were designed to be worn on all fingers, so to give yourself that option, measure your largest finger first.

Ensure that the paper or string is wrapped tightly around your finger for a secure fit. Mark the spot where it meets and measure the distance with a ruler (in mm).

See our measurement chart to find your ideal ring size. If you land on a half-size, size up!
