Enter the size of the area, pick a stone size and a fill, and get a count you can shop with.
Round stones pack best in a honeycomb: each row offset by half a stone. Each stone then occupies an area of pitch² × 0.866, where the pitch is the stone’s diameter plus the gap. The calculator divides your area by that. Scattered designs use a fraction of the full count.
The same formula reproduces the per-square-inch figures published by rhinestone suppliers, which is how we know it is in the right range. Real projects with handles, seams and letters come in a little under the estimate.
| Project | Stones (estimate) |
|---|---|
| 30 oz tumbler, full coverage, 3 mm | 7,200 |
| Phone case back, 3 mm | 1,400 |
| Pair of foam clogs, 3 mm | 3,200 |
| Hardback book cover, 3 mm | 5,000 |
| Graduation cap design, 4 mm | 1,350 |
Each object has its own guide in things to bedazzle.
Mixed kits spread their stones across many colors. If a design is mostly one color, check that color alone: a 40-color tub of 50,000 holds around 1,250 of each. Single-color bulk bags of 10,000 or more exist in most sizes.
Bulk bags in one color, for designs a mixed tub can’t fill.

A 40 oz tumbler has more wall than a 30 oz one; at 3 mm, full coverage typically runs to many thousands. Measure the circumference and decorated height and use the tumbler shape in the calculator.
A 20 × 20 cm (8 × 8 in) SS10 design at a quarter coverage is roughly 1,200 stones. Lettering is usually counted as an outline.
