Bead Sizes
Bead sizes are determined by the number of beads will fit per inch. For example, if you had size 11/0 beads, approximately 11 of them would fit along one inch of a ruler. Only 6 size 6/0 beads would fit in the same space.
The larger the bead size, the smaller the bead and the smaller the bead size, the larger the bead. For example: size 6/0 beads are about 4 times the size of size 11/0 beads and size 8/0 beads are about 2 times the size of 11/0 bead and half the size of 6/0 beads.
