How Many Beads?
How many beads do you need?
Most beads are described in one of two ways:
in millimeters and in a bead scale 22/0, 15/0, 13/0, 11/0, 10/0, 8/0, 6/0 and 5/0. The bead scale is a little backwards in that the bigger the bead the smaller the number (8/0 is larger than 15/0).
For bead stringing use the following formula:
# of inches X 25.4 ÷ size of beads = # of beads needed.
Example: A 16-inch necklace made of 4 mm beads that has a 1-inch clasp:
15 inches X 25.4 ÷ 4 mm = 95 beads
To determine the number of seed beads and other tiny beads that use the bead scale, use the following tables. Please understand that beads all vary slightly in size and weight and from manufacturer to manufacturer, so the tables are estimates.
