Enter the area to cover in square feet, the length and width of each paver in inches and the waste allowance. The count is the area in square inches divided by the paver's area, plus waste. Choose 10% for straight patterns and more for diagonal or curved layouts.
Measure the area accurately, and remember that a patio also needs a compacted base of gravel and a bedding layer of sand, which are calculated separately.
The area count does not design a base, drainage or bedding layer. Use the paver system’s specifications, site conditions and applicable design requirements. Patterns, edge cuts and spacers affect actual order quantity; the allowance is an explicit scenario input.
Paver: worked example
| Area to cover (sq ft) | 200 |
|---|---|
| Paver length (in) | 8 |
| Paver width (in) | 4 |
| Waste allowance | 10.0% |
| Pavers needed | 990 |
| Pavers per square foot | 4.5 |
Common error: Measuring the area as if it were a plain rectangle. A curved edge, a step or a border course all change the count and the waste.

A paver is a small piece with a known face, so coverage is a count: how many fit in the area. A 4 by 8 inch paver covers 32 square inches, so 4.5 fit in each square foot and 200 square feet takes 900. The waste allowance pushes that to 990, because every cut at an edge or curve leaves a piece that cannot be used elsewhere.
Order a few extra beyond the waste figure and keep them. Replacing a cracked paver later is hard if the color has been discontinued.
Estimate the gravel and sand on the material volume and cubic yard calculators, the area on the square footage page and edging on the rectangle area calculator. The tile and flooring calculators handle indoor surfaces, and the fence page covers boundaries.
Is the 10% allowance required for every pattern?
No. At 200 ft², assumed 8-by-4-inch modules give 900 pieces before allowance and 990 with the entered 10%. A cutting plan can require a different quantity.
Does this choose base depth?
No. Base and drainage requirements depend on the product, soil, loading, climate and actual design. The calculator counts surface modules.
How much base do pavers need?
Base depth is a project specification. Soil and drainage matter. Frost exposure and traffic matter too.
Four-to-six inches of compacted aggregate with one inch of bedding is a quantity scenario. It does not design every patio or driveway; use the construction required for the actual paver system and enter its specified layer depths consistently.
How many pavers are in a square foot?
It depends on the size. With 8 by 4 inch pavers, about 4.5, since each covers about 0.22 square feet.
Why buy extra pavers?
For cuts, breakage and future repairs, since later production batches may not match the color of the original order.
