Beads per Gram: Seed Beads

Have you ever been counting beads and lose track of where you are in numbers? Or do you find yourself spending too much time trying to count out various amounts of seed beads? In Better Beader Episode 112, join Allie as she shows you approximately how many seed beads there are in a gram. Rather than count beads, you can now have a reference that is very helpful when looking at patterns that call for grams.

Episode Transcript


Have you ever wondered how many seed beads are in a gram? In this informative Better Beader episode from Potomac Beads, Allie delves into the fascinating world of seed bead sizes and counts. Whether you're a beginner or an experienced beader, understanding the relationship between seed bead sizes and their count per gram can help you plan your projects more effectively and ensure you have the right amount of beads on hand. In this article, we'll break down the key points from the episode and provide a handy reference guide for estimating seed bead counts.

Seed Bead Sizes and Shapes

Seed beads come in various sizes, typically ranging from size 15/0 (the smallest) to size 6/0 (the largest). The most common sizes used in beading projects are:

  • 15/0 - Approximately 3mm in diameter
  • 11/0 - Approximately 2mm in diameter
  • 8/0 - Approximately 3mm in diameter
  • 6/0 - Approximately 4mm in diameter

It's important to note that seed bead sizes are not standardized across manufacturers, so there may be slight variations in diameter.

In addition to size, seed beads also come in different shapes, such as rocailles (round) and delicas (cylindrical). The shape of the seed bead can affect the number of beads per gram, as delicas tend to be more uniform in size and shape compared to rocailles.

Estimating Seed Beads per Gram

While the exact number of seed beads per gram can vary based on factors like size, shape, and manufacturer, here are some general estimates:

  • 15/0 rocailles - Approximately 1,700-2,000 beads per gram
  • 11/0 rocailles - Approximately 1,100-1,200 beads per gram
  • 8/0 rocailles - Approximately 400-500 beads per gram
  • 6/0 rocailles - Approximately 300-400 beads per gram
  • 11/0 delicas - Approximately 1,300-1,400 beads per gram

Keep in mind that these are rough estimates, and the actual count may differ slightly depending on the specific beads you are using.

Tips for Calculating Bead Counts

When planning your beading projects, consider these tips for calculating the number of seed beads you'll need:

  • Use a digital scale to measure out a gram of seed beads and count them for a more accurate estimate
  • Refer to the manufacturer's website or product information for specific bead counts
  • If you're unsure, it's always better to have a few extra grams of beads on hand to avoid running out mid-project


Understanding how many seed beads are in a gram is a valuable piece of knowledge for any beader. By familiarizing yourself with the general estimates for different seed bead sizes and shapes, you'll be better equipped to plan your projects and purchase the right amount of beads. Remember to use these estimates as a starting point and adjust as needed based on your specific beads and project requirements. Happy beading!
