1,323 pavers
Paver units = gross area (net × (1 + waste%)) ÷ paver face area. A 280 sq ft patio in 4×8 brick needs about 1,323 units at 5% waste.
Enter the patio area, pick paver size, base depth, and joint width units, base tons, and sand bags update live.
Compacted base = net area × (base depth ÷ 12) ÷ 27 × 1.6 tons/yd × 1.10 compaction 4 in for walkways, 6 in for driveways.
Bedding is a fixed 1-in screed sand bed per ICPI at 1.35 tons/yd. Polymeric sand: 1 fifty-pound bag per 75 sq ft of ⅛-in joints, 35 sq ft for wide ⅜-in joints.
Pavers = gross area ÷ paver size
Paver units = gross area (net × (1 + waste%)) ÷ paver face area. A 280 sq ft patio in 4×8 brick needs about 1,323 units at 5% waste; 12×12 slabs need only 294.
Compacted base = net area × (base depth ÷ 12) ÷ 27 × 1.6 tons/yd × 1.10 compaction. A 280 sq ft patio at 4 in needs about 6.1 tons of crushed base. Use 4 in for walkways, 6 in for driveways.
One 50-lb bag covers about 75 sq ft of ⅛-in joints, or 35 sq ft of wide ⅜-in joints. A 294 sq ft patio with narrow joints needs 4 bags.
4 inches of compacted crushed base for walkways and patios, 6 inches for driveways, each with a 10% compaction allowance at 1.6 tons per cubic yard.
A fixed 1-in screed sand bed per ICPI at 1.35 tons per cubic yard — about 1.2 tons for a 280 sq ft patio.
