Paver and bedding formula
pavers = project area ÷ paver face area × wastelayer volume = project area × compacted depthPavers round up to whole pieces. Base and sand are shown as geometric compacted volumes.
Paver calculator
Estimate paver pieces plus aggregate base and bedding sand for a simple rectangular patio or walkway.
Enter project and paver dimensions
Use finished compacted depths for planning; suppliers can advise how much loose material is required.
Treat the field, edge, base, and bedding as separate layers
Paver count comes from surface area, while base and bedding quantities come from compacted volume. Curves, borders, soldier courses, patterns, and small edge pieces can increase cutting loss beyond a simple rectangular field.
- Enter compacted layer depths rather than loose delivery depths.
- Use the paver's actual face dimensions including the intended joint.
- Estimate edge restraint, joint material, drainage, and excavation separately.
Plan below the surface
Required excavation and base depth depend on soil, drainage, climate, traffic, and product instructions. A driveway generally needs a different assembly than a pedestrian patio.
