Enter your patio length and width in feet, pick a paver size from the selector, and set a waste allowance for cuts and pattern trimmings. This paver estimator converts everything to square inches for the core division: patio square inches divided by one paver's square inches, multiplied by (1 + waste percent / 100), then rounded up to a whole paver. The formula uses a single division of an exact integer ratio, so the result is correctly rounded before the ceiling is applied. A tiny tolerance (1e-9) sits just under the ceiling, so floating-point noise like 396.00000000000006 still reads as exactly 396 pavers instead of rounding up to 397. The calculator also returns the patio area in square feet and the edge restraint footage, which is the perimeter, 2 × (length + width). Buy the waste allowance with the main order from the same production run so the color matches, and keep a few spares for future repairs.
A paver estimator is area math with the units lined up. First, the patio area: length in feet times width in feet gives square feet. Second, one paver's face area: length in inches times width in inches, divided by 144 (the number of square inches in a square foot), gives the paver's area in square feet. Third, the raw paver count: patio area divided by paver area. Fourth, the waste allowance: multiply by (1 + waste percent / 100) to cover cuts, breakage, and pattern trimmings. Finally, round UP to the next whole paver, because suppliers do not sell fractions of a paver. The edge restraint is separate: it follows the perimeter, so 2 × (length + width) in feet.
Measure the length and width of your patio in feet with a tape measure. If the space is L-shaped or irregular, split it into rectangles, run each one through the calculator, and add the paver counts together. Pick your paver size from the dropdown: common options are the 4x8 brick paver, the 6x6 and 6x9 squares, the 12x12 square, and the 12x24 large rectangle. Set the waste allowance slider to match your layout (10% is a safe default). The results update instantly: patio area in square feet, the number of pavers to order, and the linear feet of edge restraint for the perimeter.
Paver coverage per square foot depends only on size. A 4x8 brick paver covers 32 square inches, so 144 / 32 = 4.5 pavers per square foot. A 6x6 paver needs 4 per square foot; a 6x9 needs about 2.67; a 12x12 covers exactly 1 square foot; a 12x24 needs 0.5. Use this paver size chart when comparing products: smaller pavers mean more pieces, more joints, and a busier look, while large-format pavers cover ground faster with fewer joints. Patterns matter too. Running bond and stacked bond are simple with few cuts; 90-degree herringbone interlocks strongly for driveways; 45-degree herringbone and basketweave need more edge cuts, so the waste factor climbs with pattern complexity.
No layout wastes zero pavers: edges, curves, and corners all produce cut pieces, and a few pavers always arrive chipped. Use a 5% waste factor only for a simple rectangular patio in running bond with few cuts. Use the 10% default for a standard brick paver patio with normal edges. Step up to 15% for 45-degree herringbone, diagonal layouts, or curved borders where every edge piece is a triangle. Use 20% for intricate multi-shape or circular designs. Always buy the waste with the main order from the same production run, since pavers vary slightly in color between batches, and keep a few spare pavers for future repairs.
Take a 12x10 ft patio laid with 12x12 pavers and a 10% waste allowance. Step 1: patio area = 12 × 10 = 120 square feet. Step 2: one 12x12 paver = 12 × 12 / 144 = 1 square foot. Step 3: raw count = 120 / 1 = 120 pavers. Step 4: with waste = 120 × 1.10 = 132, and 132 rounds up to 132 pavers. Step 5: edge restraint = 2 × (12 + 10) = 44 feet. A second check: a 10x8 ft patio with 4x8 brick pavers at 10% waste is 80 square feet, each paver is 32 / 144 = 0.222 square feet, so 80 / 0.222 = 360 pavers, times 1.10 = 396 pavers to order, plus 2 × (10 + 8) = 36 feet of edge restraint. That is the exact math the calculator above runs.
A paver count tells you what you buy, but the installation cost decides your budget. In 2026 pricing, a professionally installed paver patio typically costs $10 to $25 per square foot, including the 4 to 6 inches of compacted base material, bedding sand, the pavers themselves, edge restraints and labor. Material grade drives the range: basic concrete pavers sit at the low end, while natural stone and intricate patterns sit at the high end because cutting takes longer. DIY saves the labor portion but expect 3 to 5 days of work for a standard patio, plus the cost of renting a plate compactor. Use the paver count from this calculator, price it per unit at your supplier, then add base materials and labor to build your own cost breakdown. Treat these figures as planning estimates, not a quote.
A 10x12 patio is 120 square feet. With 12x12 pavers (1 per square foot) you need 132 pavers at a 10% waste allowance. With 4x8 brick pavers (4.5 per square foot) you need 120 × 4.5 × 1.10 = 594 pavers. A 20x20 patio (400 square feet) needs 400 12x12 pavers before waste, or 440 with 10% extra. Enter your exact size above for your paver size.
Exactly 1. A 12x12 inch paver is 144 square inches, which is precisely 1 square foot. So a 100 square foot patio needs 100 of them before waste, or 110 with a 10% cutting allowance.
About 4.5. A 4x8 inch paver covers 32 square inches, and 144 / 32 = 4.5. So 100 square feet needs 450 brick pavers before waste, or 495 with 10% extra for cuts.
Add 5% for a simple rectangular patio in running bond with few cuts, 10% as a safe default for most patios, 15% for 45-degree herringbone, diagonal layouts, or curved borders, and 20% for intricate multi-shape designs. Always buy the extra with the main order so the color matches.
Yes. Diagonal edges produce triangular offcuts at every border that cannot be reused, so 45-degree layouts need roughly 10 to 15% more waste material than the same patio laid in running bond or a 90-degree pattern.
Yes. Without edge restraint the outer pavers spread and the whole field loosens over time. The restraint runs along the perimeter, so measure 2 × (length + width) in feet to size it.
Divide 144 (the square inches in a square foot) by the paver's area in square inches. For a 6x9 paver: 144 / 54 = 2.67 pavers per square foot. Multiply that rate by your patio area, then apply your waste factor.
A walk-on patio needs 4 to 6 inches of compacted gravel base, and a driveway needs 8 to 12 inches. On top of the gravel goes a 1 inch layer of bedding sand, screeded flat. A thin or poorly compacted base is the most common reason patios settle.
A professionally installed paver patio typically costs $10 to $25 per square foot in 2026, covering base material, bedding sand, pavers, edge restraints and labor. Multiply your patio area by that range for a ballpark, then price your actual paver count from this calculator at your local supplier for the material portion. DIY removes the labor cost but plan 3 to 5 days for a standard patio. These are estimates for planning, not a contractor quote.
