How to calculate pavers
Pavers are counted one by one. Find the patio area in square feet, convert it to square inches by multiplying by 144, then divide by one paver's area in square inches. Add waste for cuts. Bedding sand is the patio area times 1 inch deep, converted to cubic yards.
Formula: pavers = patio area (sq ft) × 144 ÷ (paver length × paver width) × (1 + waste %), rounded up
Worked example: 12 ft × 10 ft patio, 12×12 in pavers
Patio area = 12 × 10 = 120 sq ft, which is 17,280 sq in. One paver is 144 sq in, so 17,280 ÷ 144 = 120 pavers. Add 10% waste: 132 pavers. Bedding sand at 1 inch deep: 0.37 cubic yards.
Base layers
Patios need about 1 inch of bedding sand over 4 to 6 inches of compacted gravel. Driveways need a deeper gravel base. Skipping the base is the most common cause of sinking pavers.
