Understanding Seed Beads: Types, Shapes & Sizes

Seed beads are small, uniformly shaped beads that come in a variety of finishes, sizes, and styles. When choosing the right seed bead for your project, it’s important to understand their differences, as each type has unique characteristics. Below is a breakdown of three popular types of seed beads:

Czech Seed Beads (Preciosa)

Origin: Made in the Czech Republic by Preciosa.

Shape: Slightly rounded, donut-like shape with soft edges.

Hole Size: Typically smaller than Japanese seed beads; varies based on size (e.g., Size 11/0 has approx. a 0.6mm hole).

Characteristics: Czech seed beads are known for their slight irregularity, which gives a more organic, textured look to beadwork. They work well for traditional bead embroidery, bead stringing, and some weaving techniques.

Miyuki Delica Beads (Cylinder Beads)

Origin: Made in Japan by Miyuki.

Shape: Cylindrical, tube-like with sharp, flat edges for precise, uniform alignment.

Hole Size: Larger than standard seed beads (e.g., Size 11/0 has approx. a 0.8mm hole).

Characteristics: Delicas are highly uniform and fit together perfectly, making them ideal for peyote stitch, loom weaving, and brick stitch. Their precise shape allows for clean, professional-looking beadwork with tight, even spacing.

Miyuki Japanese Seed Beads

Origin: Made in Japan by Miyuki.

Shape: Rounder than Delicas but more uniform than Czech seed beads.

Hole Size: Larger than Czech seed beads but slightly smaller than Delicas (e.g., Size 11/0 has approx. a 0.7mm hole).

Characteristics: These beads have smooth, even shapes with larger holes, making them great for intricate bead weaving, embroidery, and stringing. They are known for their high-quality finishes and excellent durability.

Seed Bead Sizing Guide

Seed beads are sized using a number system like 6/0, 8/0, 11/0, etc. The larger the number, the smaller the bead. Here’s a quick reference:

6/0 – Approx. 4mm diameter, large holes (best for stringing and leather wrap bracelets).

8/0 – Approx. 3mm diameter, medium holes (great for weaving and embroidery).

11/0 – Approx. 2mm diameter, standard size (most commonly used for bead weaving).

15/0 – Approx. 1.5mm diameter, very tiny (ideal for intricate beadwork and fine details).
