How the math works

  1. Area: 60 ft × 40 ft = 2400 sq ft
  2. Base volume @ 4": 2400 × (4 ÷ 12) = 800.00 cu ft
  3. Add 15% for compaction: 800.00 × 1.15 = 920.00 cu ft = 34.07 yd³
  4. Tons: 34.07 yd³ × 1.4 t/yd³ = 47.70 tons
  5. Sand @ 1": 2400 × (1 ÷ 12) × 1.10 = 220.00 cu ft = 8.15 yd³
  6. Pavers: 2400 sq ft × 4.5 × 1.10 = 11,881 pavers

Trade pro tips

  • A 40x60 patio (2400 sq ft) at 4" base needs about 47.70 tons of base rock — have it dumped on a tarp near the dig.
  • Excavate base depth + 1" sand + paver thickness (2-3/8" for standard pavers).
  • Compact the base in 2" lifts with a plate compactor — one thick lift never gets dense.
  • Screed bedding sand to exactly 1". Thicker sand causes pavers to rut and shift.
  • Use edge restraint on every side not held by a wall or slab, spiked every 12".
