Okay time to get started - How big is you Cell Phone?
Length times Width will give you the area of a surface.
Example: if the phone was 2 by 4 Inches, then it would have 8 square inches of surface.
We have to know how many of what size rhinestone you need to cover 8 Square Inches.

| Stone Size | Diameter Millimeters | Square Millimeters | Number Required to Cover One Square Inch |
| 5SS | 1.8 | 2.54 | 253 |
| 6SS | 2.0 | 3.14 | 205 |
| 7SS | 2.2 | 3.80 | 170 |
| 8SS | 2.3 | 4.15 | 155 |
| 9SS | 2.6 | 5.31 | 121 |
| 10SS | 2.8 | 6.16 | 105 |
| 12SS | 3.0 | 7.07 | 91 |
| 16SS | 4.0 | 12.57 | 51 |
| 20SS | 4.7 | 17.35 | 37 |
| 30SS | 6.4 | 32.17 | 20 |
| 34SS | 7.1 | 39.59 | 16 |
| 40SS | 8.6 | 58.09 | 11 |
| 42SS | 9.1 | 65.04 | 10 |
| 48SS | 11.0 | 95.03 | 7 |
1 Square Inch = 645.16 Square Millimeters
How To Calculate the Area of a Circle
1. Divide the diameter by 2 to find the radius.
2. Square the radius, that is, multiply it by itself. For example, the radius is 4 mm, then the square of that would be 4 x 4 which is 16mm.
3. Multiply the answer from step 2 (radius squared) by pi (3.1416). This is the area.

So if we use all of the numbers that we have pulled to together this is what we get |
| Stone Size | Number Required to Cover One Square Inch. | Number of Inches | Final Number of Rhinestones Needed |
| 5SS | 253 | 8 | 2,028 |
| 6SS | 205 | 8 | 1,642 |
| 7SS | 170 | 8 | 1,357 |
| 8SS | 155 | 8 | 1,242 |
| 9SS | 121 | 8 | 972 |
| 10SS | 105 | 8 | 838 |
| 12SS | 91 | 8 | 730 |
| 16SS | 51 | 8 | 411 |
| 20SS | 37 | 8 | 297 |
| 30SS | 20 | 8 | 160 |
| 34SS | 16 | 8 | 130 |
| 40SS | 11 | 8 | 89 |
| 42SS | 10 | 8 | 79 |
| 48SS | 7 | 8 | 54 |

I would suggest the 10SS rhinestones the smaller the rhinestone, the less likely it is to be ripped off when handled roughly.
The larger the rhinestone, the more likely it is to be torn off leaving a very shiny silver spot where a rhinestone used to be. You will be much more happy with the look of 10ss stones as opposed to larger rhinestones. If you have a steady hand and good eyes, then go with a smaller rhinestone for an extraordinary look. Of course, if you use a smaller rhinestone, you will need more rhinestones.
If you choose to interleave your rows of rhinestones offset every other row for a very tight set, then you will need more rhinestones, up to 1/3 more.
