How the math works

  1. Area: 16 ft × 12 ft = 192 sq ft
  2. Base volume @ 4": 192 × (4 ÷ 12) = 64.00 cu ft
  3. Add 15% for compaction: 64.00 × 1.15 = 73.60 cu ft = 2.73 yd³
  4. Tons: 2.73 yd³ × 1.4 t/yd³ = 3.82 tons
  5. Sand @ 1": 192 × (1 ÷ 12) × 1.10 = 17.60 cu ft = 0.65 yd³
  6. Pavers: 192 sq ft × 4.5 × 1.10 = 951 pavers

Trade pro tips

  • A 12x16 patio (192 sq ft) at 4" base needs about 3.82 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".
