Bead Sizing Information
How many beads per strand inch?
To do the calculations yourself you'll need three numbers:
-
the length of the strand,
-
the size of the beads, and
-
the metric conversion.
The metric conversion of 1 inch is 25.4mm.
​
So to figure out how many beads per strand, you need to first multiply the length of the strand by 25.4. Then divide that number by the size of the beads. This will give you the approximate number of beads per strand.
​
Our strands are approximately 40cm.
The metric conversion of 40cm is 15.748 inches
​
Formula: Length of Strand (15.748) × 25.4 (Millimeters Per Inch) ÷ Bead Size (mm)
​
For Example:
​
If you have an 8 inch strand with 6mm beads your calculation would be: 8 inches (the length of the strand) x 25.4 (millimeters per inch) = 203.2 ÷ 6mm (the bead size) = 33.86 beads per strand.
​
This means that there are approximately (33) 6mm beads per 8 inch strand.
​
Calculating The Number of Beads Needed for a Project
​
This formula is also helpful when you are making a bracelet or necklace. To make an 18 inch necklace using only 8mm beads, you would calculate as follows:
​
18 x 25.4 = 457.20 → 457.20 ÷ 8mm = 57.15
​
To be on the safe side we recommend (58) 8mm beads for the 18 inch necklace just to make sure you have enough to complete the project.
