Use the chart below to determine how many of a certain size bead it takes to cover one inch of a beaded strand. This can help you plan out a bead stringing design, or calculate how many beads you'll receive when you purchase beads by the strand.
To estimate how many beads make up a strand of a certain length, multiply the beads-per-inch (from the right-hand column, below) by the length of the strand in inches. Here's an example.
- Question: How many 6mm beads are in a 16-inch strand?
- Calculation: 4.2 (beads per inch) x 16 (strand inches) = 67.2 beads
- Answer: About 67 beads.
Tip: To estimate the number of beads per inch for a bead size not shown below, simply divide 25.4 by the length of your beads in millimeters. (There are 25.4 millimeters in one inch.)
