Paver Patio Calculator

This calculator sizes a paver patio project: how many individual pavers to buy, how much crushed-stone base and bedding sand to order, how much edge restraint is needed, and a rough total material cost. Patio Length and Patio Width set Patio Area directly, and that area alone drives Base Material, Bedding Sand, and Estimated Material Cost -- none of those three change with the size of paver you pick. Pavers Needed works differently: it divides Patio Area by the coverage of a single unit, computed from Paver Length times Paver Width, so a bigger paver covers more ground and fewer units are needed to fill the same patio, and a smaller paver needs more of them.

Pattern Type layers a waste allowance on top of that paver count -- Running Bond and Basketweave add roughly 5%, Herringbone adds roughly 10% because its diagonal cuts waste more material at the edges -- but that allowance only touches Pavers Needed; Estimated Material Cost is priced from area and tonnage, not from the paver count itself, so the pattern you choose never shifts the dollar total shown. Edge Restraint defaults to auto-calculating from the patio's perimeter when left at zero, or accepts a specific linear-foot figure typed in directly.
