Seed Bead Sizes – Types of Seed Beads
When you’re trying to find the perfect seed bead sizes for your next project, you will come across 4 varieties that are available in the market nowadays. There are 2 types of different types of seed beads that are high quality and manufactured in Japan. The other type of high-quality seed beads come from the Czech Republic and the fourth type of seed beads are the more economical Chinese manufactured seed beads.
Japanese Seed Beads
Japanese seed beads are manufactured by a lot of different companies. The most commonly available and known ones are Miyuki, Toho, and Matsuno.
Japanese Cylinder Seed Beads
The highest quality seed beads that you can get are Japanese cylinder beads. They are shaped in a cylindrical shape that is consistent throughout all the beads. The glass beads are made using state-of-the-art machinery. These beads are very lightweight and uniform with oversized holes that make them easy to use and perfect for embroidery and bead weaving projects. With the precise shape and weight of these seed beads, you will have to pay a little extra but it all is absolutely worth it.
Japanese Round Seed Beads
Round seed beads are made by many different Japanese manufacturers and are sold all around the world. They are made from high-quality glass and uniform in their shapes and sizes. These beads have large holes which help in threading even if you have no experience with seed beads. Again, since these beads are made using state-of-the-art technology, they will be more on the expensive side. With the uniformity these seed beads have, you will not regret paying a little extra when your finished project looks extra polished.
Czech Seed Beads
The third type of seed beads you can get in the market are Czech seed beads. They are manufactured in the Czech Republic and are usually in a donut shape made from glass. They don’t have very big holes so they are more suited to jewelry making and not bead-making projects. Czech seed beads are not uniform in size and shape and will not give your finished craft a uniform look but will be great for projects where you want to add depth and dimension. The price point of these seed beads is cheaper than Japanese seed beads owing to the slightly lower quality and non-uniformity in their shapes.
Chinese Seed Beads
If you’re looking for seed bead sizes that are more for everyday crafting and don’t cost a lot of money, Chinese seed beads are the ones for you. These seed beads come in a lot of different materials and finishes and sometimes even have different shapes. Usually, you would use these beads for jewelry making as they make great spacers but they can also be used for crafts that may be for kids as they come in a lot of fun colors and designs. With each batch that is produced, the size of the hole and the uniformity and quality differ.
Seed Bead Sizes
A lot of high-quality seed beads are classified according to size using numbers that are called aught sizes. When seed beads were first produced there was only one standard size and that was called the ‘aught’ beads. As different varieties of seed beads started coming into the market, the sizing of seed beads started taking shape. The way seed beads are sized comes from how many beads can be lined side by side, with the holes facing up, in the space of one inch.
The basic rule of thumb with seed bead sizing is the larger the number, the smaller the seed bead.
