Seed Beads Per Gram Reference Chart
Many seed beads are sold by weight rather than by piece count, making it difficult to estimate how many beads you will receive in a package. The number of beads per gram varies depending on bead size, shape, and manufacturer. This chart provides approximate bead counts per gram for popular seed bead sizes, helping you estimate quantities needed for bead weaving, jewelry making, loom work, and embroidery projects.
