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
Example
| Input | Value |
|---|---|
| Length | 18 cm |
| Diameter | 8 mm |
| Strands | 1 |
| Total beads | 22 |

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.
