How to figure out how many rhinestone you need for a project (Part 1)

One of the most frequent questions I get from customers is “how many rhinestones will I need?” There is a mathematical formula (Yes, I see your eyes rolling and hear the groans!)

For a straight line of rhinestones:
Step A. Multiply the number of inches by 25.4
Step B. Then divide by the millimeter size of the rhinestone. So for:
                3.1 for 12ss (3.1 is the mm size for 12ss rhinestones)
                3.9 for 16ss (3.9 is the mm size for 16ss rhinestones)
                4.76 for 20ss (4.76 is the mm size for 20ss rhinestones)
 
But how is this applied? Let’s explain with pictures.

Here’s a picture of a line of 12ss rhinestones against a ruler. Step A  - The number of inches is 1 multiplied by 25.4 = 25.4. Step B – Divide by 3.1 for size 12ss rhinestones. 25.4 divided by 3.1 is 8.19 or eight rhinestones and as you can see from the picture, 8 size 12ss rhinestones fit into 1 inch.
 

Here’s a picture of 16ss rhinestones. The number of inches – 1 x 25.4 = 25.4. 25.4 divided by 3.9 equals 6.51and as you can see 6 size 16ss rhinestones fit into one inch.

Here’s a picture of 20ss rhinestones. 1 inch x 25.4= 25.4. 25.4 divided by 4.76 equals  5.33 and again you can see there are 5 size 20ss rhinestones that fit into 1 inch. 

For more than one inch, just plug in the number of inches into the formula.
