Bead Count Calculator — Beads Per Strand
Work out how many beads you need for a necklace, bracelet or strand based on length, bead size and shape.
Total finished length including clasp
Diameter of your main beads
Shape affects how much strand length each bead uses
Spacer bead or gap between each bead (0 if none)
Length taken up by clasp, jump rings and crimp covers
Single strand or multi-strand design
Cost per bead for total estimate
How We Calculate This
The calculator subtracts clasp length from the total strand length to get usable stringing length, then accounts for bead shape, spacers and knotting.
The formula
Effective bead length = Bead diameter x Shape multiplier
Beads = floor(Usable length / (Effective bead length + Spacer + Knot allowance))
Shape multipliers: Round 1.0, Rondelle 0.6, Oval 1.2, Bicone 0.8, Tube 1.5
