Different manufacturers make seed beads slightly differently.

• Miyuki seed beads are known for very consistent shape and size.
• Toho seed beads often have slightly larger holes, which makes them great for multiple thread passes.

• All three brands come in similar size numbers, but the exact measurements can vary slightly.

Choosing the Right Size for Your Project

The best seed bead size depends on your project, the level of detail you want, and the techniques you plan to use. Larger seed beads are generally easier to handle, while smaller sizes create finer, more intricate designs.

If you’re just getting started with bead weaving, 8/0 or 11/0 seed beads are excellent choices because they are widely available, easy to work with, and used in many beginner-friendly patterns.

You might choose:
• 2/0–4/0 Seed Beads
Perfect for chunky necklaces, bracelets, decorative accents, leather strings, macramé, kumihimo, and statement jewelry.

• 6/0 Seed Beads
Ideal for beginner projects, bold bead weaving, fringe, and jewelry that benefits from larger beads.

• 8/0 Seed Beads
A versatile size for stringing, bead embroidery, simple bead weaving, and everyday jewelry designs.

• 11/0 Seed Beads
The industry standard for peyote stitch, brick stitch, herringbone, right-angle weave, loom work, and most bead weaving patterns.

• 15/0 Seed Beads

Other things to consider:
• The larger the bead, the fewer you’ll need to complete a project.
• Smaller seed beads create finer detail but require more patience and precision.
• Not all manufacturers measure seed beads exactly the same. Beads with the same size number may vary slightly in diameter, hole size, and overall shape.
• Larger holes allow additional thread passes, which can be important for certain bead weaving stitches.
• When following a pattern, use the recommended bead size whenever possible to achieve the intended finished dimensions.
