Paver Calculator

Divide total square footage by each paver's square footage. Standard 6×9" pavers cover 0.375 sq ft each, requiring 2.67 pavers per square foot. Add 10% for straight patterns, 15% for diagonal, 20% for herringbone due to cutting waste. Also calculate edge restraints (perimeter linear feet) and polymeric sand (50 lb bag per 50-75 sq ft).

Standard paver base: 4-6" (10-15cm) compacted crushed stone base + 1" (2.5cm) leveling sand. For driveways, use 6-8" base. Compact base in 2" lifts to 95% density. Use geotextile fabric over clay soil. Proper base prevents settling and shifting. Skimping on base is the #1 cause of paver project failure.

Paver costs: USA $0.50-5 per paver or $3-15/sq ft; UK £25-80/m²; EU €20-70/m²; Australia A$30-100/m². Basic concrete pavers are cheapest; clay, natural stone, and premium styles cost more. Installation adds $5-15/sq ft or €30-100/m². Total installed patio: $10-25/sq ft. DIY saves 50% but requires proper tools and technique.

Running bond (brick pattern) is simplest with 10% waste. Stack bond looks modern but is weakest structurally. Herringbone (45° or 90°) is strongest for driveways—interlocking resists shifting but needs 15-20% extra pavers. Basketweave is decorative. Complex patterns require precise cuts. Choose based on aesthetics, traffic load, and budget for waste.

Yes, edge restraints are essential to prevent pavers from shifting outward over time. Options include: plastic/aluminum paver edging (most common, $0.50-2/ft), concrete curbing, existing structures, or soldier course borders. Install edging before laying pavers. Stake every 12-18" into compacted base. Without restraints, pavers will separate within months.

Use polymeric sand between pavers—it hardens when wet, preventing weed growth and insect infiltration while locking pavers together. Regular sand washes out and allows weeds. Apply polymeric sand dry, sweep into joints, and activate with water per manufacturer instructions. One 50 lb bag covers 50-75 sq ft. Avoid wetting before sweeping excess.
