How it’s calculated
- Pavers = area ÷ ((length + joint) × (width + joint)) × (1 + waste %)
- Base and sand = area × depth
Worked example
100 sq ft patio with 4 × 8 in pavers, 5% waste, 4 in base, 1 in sand.
Inputs
- Areas
- 10 × 10 ft
- Paver length
- 8 in
- Paver width
- 4 in
- Joint width
- 0 in
- Waste for cuts
- 5 %
- Gravel base depth
- 4 in
- Bedding sand depth
- 1 in
Results
- Pavers
- 473 pavers
- Gravel base
- 1.23 cu yd
- Bedding sand
- 0.31 cu yd
- Area
- 100 sq ft
Assumptions and limits
- Base volume is before compaction; order 10–20% more for compacted base.
- Edge restraints and polymeric sand are not included.

Questions
How many 4×8 pavers per square foot?
4.5 pavers per square foot (144 ÷ 32).
How much base do I need under pavers?
About 4–6 in of compacted gravel base for foot traffic, 8–12 in for driveways, more on clay soils.
