Paver Calculator
Count the pavers for a patio or walk, with cuts and waste added.
pavers = 100 sq ft × 4.5/ft² + 5% = 473
Pavers are counted from area, not volume. The calculator multiplies the patio length by its width to get the surface area, then divides by the face area of a single paver to find how many cover the space. A 4-by-8-inch paver has a face of 32 square inches, and since a square foot is 144 square inches, that works out to a tidy 4.5 pavers per square foot — the number the industry quotes.
Real installations lose pavers to cuts along curves, borders, and any angled pattern, so a waste allowance is added on top of the exact count. Five percent covers a simple grid or running bond; herringbone and other diagonal layouts cut more pavers and want ten percent. The final number is always rounded up to a whole paver, because you cannot buy part of one.
Because pavers are ordered by the pallet, it is worth rounding your final count up to a sensible pallet quantity and keeping a few spares for future repairs.
