An 8-by-4-inch paver covers 32 square inches, so 4.5 pavers cover one square foot before joint or pattern adjustments."},{"question":"How much waste should I add for pavers?","answer":"About 5% may suit a simple running bond in a square area, while 10% is a common planning allowance. Curves, diagonals, herringbone, mixed sizes, many cuts, or desired repair stock can require 15% or more."},{"question":"Does paver spacing change the quantity?","answer":"Yes. Manufacturer coverage often includes the designed joint width, while multiplying actual stone face dimensions does not. Prefer the product’s published square-feet-per-pack coverage for interlocking systems or mixed modules when available."},{"question":"Does this estimate include the patio base?","answer":"No. It estimates surface pavers only. Base aggregate and bedding depend on excavated area, compacted lift thickness, soil, drainage, climate, and application. Calculate those volumes separately and follow the pavement system’s installation specification."}],"sources":[{"name":"Interlocking Concrete Pavement Institute — Construction Resources","url":"https://icpi.org/resources/","note":"Industry reference for interlocking concrete pavement design and installation."}],"defaultCalculation":{"inputs":{"length":18,"width":12,"paverLength":8,"paverWidth":4,"piecesPerPack":120,"waste":10},"result":{"value":"1,070","unit":"pavers","label":"Paver pieces required","lines":[{"label":"Full packs to buy","value":"9 packs"},{"label":"Project surface","value":"216 sq ft"},{"label":"Pavers before waste","value":"972"},{"label":"Pavers supplied by full packs","value":"1,080"}],"summary":"The field area needs 972 pavers before pattern waste and whole-piece rounding.","note":"Actual pack coverage may account for joint width or mixed sizes.
