Patio Calculator
Plan a typical segmental paver system: compacted gravel base plus a sand bedding layer before pavers. Enter the patio length and width, then each layer thickness. Default bulk densities are 1600 kg/m³ for both layers—adjust if you use open-graded base or a specific sand.
Sand-only bedding: patio sand calculator. Pavers: paver gravel calculator.

Edge restraints and cuts
Field trimming and edge stakes do not change area much on large rectangles; add a small waste allowance on small jobs with many curves.
