How the Bead Strand Calculator works
Beads = finished length in millimetres ÷ bead diameter, rounded down. String length = finished length + extra for the clasp, knots, and tails. Spacers, knots between beads, and uneven bead sizes change the count, so lay the beads on a bead board before stringing. Example: with Finished length 18 in, Bead diameter 6 mm, and Extra for clasp and knots 2 in, the result is Beads needed = 76; String length to cut (in) = 20; String length to cut (cm) = 50.8.
