How to use this
Subtract clasp + crimp + jump ring length (typically 1-2 in) from your finished length before dividing by bead size. Add spacer beads if you're using them — every spacer takes a slot a main bead would fill.
Most beads come on 16-inch strands. Divide your needed bead count by the strand count to know how many strands to order, rounded up.
Formula
count = (length_mm − clasp_mm) ÷ (bead_mm + spacer_mm)
