Summary
The Bead Count Calculator tells you exactly how many beads to buy for any stringing project. Enter your project length, bead diameter, spacing between beads, and number of strands — the tool instantly returns the per-strand count, total bead count, and a recommended shopping quantity with a 10% buffer. Works in millimeters, centimeters, or inches.
How it works
- Enter the total length of your project (bracelet, necklace, curtain, etc.).
- Enter the diameter of one bead in the same unit.
- Optionally enter a gap (space between beads) if you are using spacers or knots.
- Set the number of strands if you are making a multi-strand design.
- The calculator shows how many beads you need per strand and in total, plus a shopping buffer.
Use cases
- Figure out how many beads to buy for a bracelet before visiting a craft store.
- Calculate seed bead quantities for a multi-strand necklace.
- Plan curtain beading — how many beads fit on each strand for the desired length.
- Estimate bead quantities for friendship bracelets as a group project.
- Compare bead counts when switching between 4 mm and 6 mm beads.
- Add a 10% buffer automatically to avoid running short mid-project.
