Sizing and Bead Quantity for Round Bead Strands
Bead Size (millimeters) Approximate Bead Size (inches) Approximate # on 16" Strand
4mm 3/16" 94
6mm 1/4" 66

Note that sizes given are nominal. Actual size of a bead will be less than +/- .5mm from the given size in millimeters. This is common practice in the bead industry. Most beads will actually be very close to the given size, but be aware that this size variance is possible. For reference, a dime coin is about 18mm in diameter.
