A paver calculator works out how many pavers a patio or path needs from the area to cover and the size of a single paver. Pavers are laid across an area but bought as units, so the count is the area divided by the size of one paver - plus the extra you always need for the cuts around edges and curves and the odd one that cracks. The tool divides the paving area by the area of a single paver and adds about 10% for cuts and breakage. Enter the paver's length and width in inches; the mix of sizes in a pattern averages out, but for a single-size layout this is accurate. A pattern with lots of diagonal cuts - herringbone at 45 degrees - generates more waste, so lean toward 15% for those. Base material, sand and edge restraints are separate from the paver count here.
Using Paver Calculator
- Measure the paving rectangle in feet, then enter one paver's length and width in inches. Use the actual coverage dimensions supplied for the product.
- The tool divides project area by one paver's area, adds 10% and rounds up to a whole paver. It assumes a single rectangular paver size rather than a mixed-size laying pattern.
- Convert the resulting unit count to complete packs or pallets using the supplier's quantity. Check whether colour blends require mixing units from several packs before laying them.
Where paver calculator helps
Before you use the result
- For 120 square feet and 8 by 4 inch pavers, each paver covers 32/144 square feet. The area count is 540, rising to 594 with the included 10%. Confirm the product's joint and coverage convention before treating that arithmetic as an order.
- Herringbone, curves, borders and diagonal cuts can consume more pieces than a rectangular grid. The tool has no adjustable waste field; record any extra layout allowance separately and avoid applying the included 10% twice.
- Base aggregate, bedding sand, jointing material, drainage and edge restraints are not included. Nor does the count assess load capacity or ground conditions. A patio and a vehicle driveway can have the same area while needing different construction below the pavers.
Questions about Paver Calculator
How many extra pavers should I buy?
About 10% over the exact count for cuts and breakage, or 15% for diagonal patterns with more cuts. The tool includes 10% by default.
