How Many Seed Beads Do I Need?

You can estimate the number of beads you will need to a project if you know the size of your beads. These charts and tables are a useful guide to help you.

Please note that beads of a stated size are not always the same size or weight. Also, differences in thread tension can add up to big differences in finished dimensions.

These charts are approximations and should only be used as a gudie. I find it is always best to overestimate than underestimate!
