What is bead pattern calculator?
A bead pattern calculator estimates how many beads a rectangular pattern needs and converts that count into a rough weight. It is especially useful before ordering beads for bracelets, panels, loom strips, or charted designs.
How to use this calculator
- Choose bead size and stitch type.
- Enter pattern width and length in beads.
- Enter color count.
- Round up for mistakes, sorting, and color balance.
How is it calculated?
Formula
total beads = beads wide x beads long; per color = total beads / color count What The Constants Mean
- 11/0 seed beads per gram (110): Approximate count for common 11/0 seed beads; brand and finish vary.
- Delica beads per gram (180): Approximate count for uniform cylinder beads; exact counts vary by finish.
A 30 by 80 bead design contains about 2,400 beads before extras.
Common mistakes
Per-color estimates are averages unless you know exact color percentages. Complex motifs can use one color much more heavily, so chart counts are better for final ordering.
FAQ
How many beads should I buy extra?
Buying 10% to 20% extra helps cover dropped beads, culling, and color variation.
Are grams exact?
No. Beads per gram vary by brand, finish, and bead shape.
Does stitch type change bead count?
The rectangular count is similar, but thread path and edge shaping vary.
Can I use this for loom work?
Yes, for bead count estimates. Warp threads still need separate planning.
