Seed Bead Sizes Explained
Seed beads are sold using a number size such as 6/0, 8/0, 11/0, or 15/0.
The number refers to the size of the bead, but it works opposite of what many beginners expect.
The larger the number, the smaller the bead.
For example:
6/0 beads are larger
11/0 beads are medium sized
15/0 beads are very small
Understanding seed bead sizes helps you choose the right beads for your jewelry and bead weaving projects.
Common Seed Bead Sizes
Here are the seed bead sizes most commonly used in jewelry making.
6/0 Seed Beads (about 4mm)
Large seed beads often used for chunky designs, fringe, and beginner projects.
8/0 Seed Beads (about 3mm)
Medium-large beads often used in stringing and simple beadwork.
11/0 Seed Beads (about 2mm)
The most popular seed bead size. These are widely used in bead weaving, loom work, peyote stitch, and brick stitch.
15/0 Seed Beads (maybe 1.5mm)
Very small seed beads used for delicate edging, detailed beadwork, and intricate designs.
Why Seed Bead Sizes Matter
Choosing the correct bead size affects:
how your pattern fits together
the number of beads required
the overall look of your jewelry
Many bead weaving patterns specifically call for 11/0 seed beads because they are versatile and widely available.
Miyuki vs Toho vs Czech Seed Beads
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.
Czech seed beads have a more traditional rounded shape and are popular for stringing and embroidery.
All three brands come in similar size numbers, but the exact measurements can vary slightly.
Choosing the Right Size for Your Project
If you are just getting started with bead weaving, 11/0 seed beads are usually the easiest size to work with.
You might choose:
8/0 or 6/0 for bold designs
11/0 for most bead weaving patterns
15/0 for fine detail and edging
