How Many Pavers for a 12x20 Patio?

A 12 × 20 ft patio (240 sq ft) takes 1188 pavers in the standard 4 × 8 in size, including 10% for cuts. Underneath you need about 4.8 tons of base gravel for a 4 inch base and 40 bags (50 lb) of bedding sand.

How it's worked out

  1. Area: 12 × 20 = 240 sq ft
  2. Pavers: 240 × 4.5 pavers per sq ft = 1,080, plus 10% = 1188
  3. Base: 240 × 4 in ÷ 12 ÷ 27 × 1.15 for compaction = 3.41 yd³ ≈ 4.8 tons
  4. Sand: 240 × 1 in ÷ 12 = 20 cu ft = 40 bags

Herringbone and curved designs waste more, so allow 15% for those. You'll also need polymeric joint sand and edge restraint around the sides that aren't against a wall.
