How Many Beads Will I Need?

Assorted sizes and shapes of seed beads.

Jennifer VanBenschoten
Trying to estimate how many beads you might need to make any given project can be a tough thing to figure out. Seed bead sizes can vary widely, depending on the type of seed bead you are using. There are also slight differences in the weight of seed beads depending on the finish of the bead. Metal seed beads will weigh much more than glass seed beads, resulting in less beads per gram than glass beads.

Use this table to figure out how many seed beads you will need when bead amounts are measured in grams. This table also gives an estimate of how many beads you will need when strung end-to-end.

If you are doing loomwork, square stitch or Ndebele (herringbone) stitch, you can use this table to figure out the approximate number of beads per square inch or per square centimeter.

Remember that the amounts and measurements given in these tables are only estimates. They were calculated by weighing and measure opaque black Japanese seed beads and cylinder beads. Always buy more seed beads than you think you will need for a project to avoid running out in the middle of the project.
