How the paver estimate works
Divide the patio area by the area of one paver, then add 5 percent for cuts around edges. A solid patio also needs a compacted base, usually about 4 inches of gravel, and a 1 inch bedding layer of sand. Diagonal and herringbone layouts cut more, so lean toward 10 percent waste for those.
