What this calculator does
Paver sand needed works out volume and weight of bedding or joint sand needed to cover a paver area at a given depth. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaVolume = area × depth; weight = volume × sand density
The inputs explained
| Field | What to enter |
|---|---|
| Area to cover (sq ft) | A number, measured in sq ft. Starts at 200. |
| Sand depth (in) | A number, measured in in. Starts at 1. |
| Sand density (typical sand ≈ 100 lb/cu ft) (lb/cu ft) | A number, measured in lb/cu ft. Starts at 100. |
