STANDARD JEWELRY LENGTHS AND NUMBER OF BEADS NEEDED

See what a range of necklace sizes look like, get standards for bracelets and anklets, and find out how many beads you’ll need to achieve them with these charts and information blocks.

But how many beads will I need?

Well, even without an Intel Inside Pentium Processor, you can calculate the number of beads needed for a strand using the following formula:

Just remember that 1 inch = 2.54cm = 25.4mm (1cm = 10mm). So, multiply the length of the necklace by 25.4 and divide by the size of the beads in millimeters.

Examples:

1) 18-inch necklace made with 4mm beads:

Number of beads = 18x25.4/4 = 114

2) 32-inch necklace made with 6mm beads:

Number of beads = 32x25.4/6 = 135

Remember: since beads may be irregular, this number is approximate. Also, if you are knotting between the beads, add 1 or 2mm for each knot, depending on the thickness.

In case you don't remember...
