How many pavers do I need?
Enter your patio or walkway dimensions and the size of one paver. The calculator divides the area by a single paver's face area, adds 10% for cuts and breakage, and rounds up to whole pavers — the count works the same for concrete, brick and stone pavers.
It also estimates what goes underneath: a 1-inch bedding layer of paver sand and 4 inches of compacted gravel base, both as tonnage. Ordering the bedding layer separately? Use the sand calculator.
Formula & methodology
pavers = patio ft² ÷ (paver L in × paver W in ÷ 144), + 10% waste
One paver's face area is converted from square inches to square feet (÷ 144). The 10% allowance covers edge cuts; diagonal and herringbone patterns can need 15%.
All constants are published on the material reference; the full model is on the methodology page.
12 ft × 12 ft patio, 4"×8" pavers: you need 648 pavers (buy 713 with waste), about $285.2–$1,069.5 in materials. See how we calculate this →
