  2. 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. Unwrap your marked length. With a ruler, measure it in either in millimeters or inches. Enter your measurement below.
