Necklace Lengths

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 = 108
2) 32 inch necklace made with 6mm beads: Number of beads = 32x25.4/6 = 128

Remember: since beads may be irregular, this number is approximate.
