Patio Paver Calculator
Calculate how many pavers you need plus sand and gravel for the base.
Enter patio and paver dimensions for an accurate material list.
Materials Needed
Patio Paver Count divides the patio area by the area of a single paver, then adds waste.
Pavers Needed = (Patio Area / Paver Area) × (1 + Waste %)
Base materials are calculated from the patio area and recommended depths:
Gravel Base (4 in / 10 cm deep): Volume = Patio Area × Depth
Sand Bedding (1 in / 2.5 cm deep): Volume = Patio Area × Depth
Unit conversions:
Imperial: Patio in feet, pavers in inchesMetric: Patio in meters, pavers in centimeters
Common paver sizes (imperial):
- Standard brick: 4×8 in
- Holland: 6×6 in
- Large format: 12×12 in, 12×24 in
Common paver sizes (metric):
- Standard brick: 10×20 cm
- Holland: 15×15 cm
- Large format: 30×30 cm, 30×60 cm
Tips:
- Add 10% waste for running bond, 15% for herringbone patterns
- Compact gravel base to 95% density before laying sand
- Use polymeric sand between joints to prevent weed growth
