Count the beads for a piece

Enter the desired length and the bead diameter (and the number of strands): the tool gives the beads per strand and the total.

The method

  • Beads/strand = length (mm) ÷ diameter
  • Total = beads/strand × number of strands
  • Subtract the clasp length
  • Buy 5–10% extra beads

Frequently asked questions

How are beads counted?

Beads = length (in mm) ÷ bead diameter, rounded down. E.g. 18 cm ÷ 8 mm → 22 beads.

Should I subtract the clasp length?

Yes, for accuracy: subtract the clasp size from the total desired length.

What about multiple strands?

Enter the number of strands: the tool multiplies the beads per strand by that number.

Should I buy spare beads?

Yes, allow 5 to 10% extra beads for losses and trials.
