Updated 2026-10-20 · Based on: standard block, brick and paver sizes with their mortar joints.
How to use the Paver Calculator
- Enter the patio length and width.
- Pick the paver size and joint width.
- Set the base depth (4 in for patios, 6–8 in for driveways) and sand depth (1 in).
- Read pavers, base and sand.
Formula
Pavers = area ÷ ((paver length + joint) × (paver width + joint)) × (1 + waste).
Base gravel = area × depth × 1.15 (it compacts); bedding sand = area × 1 in.
