The formula
Pavers per sq ft = 144 ÷ (paver length in × paver width in)
Pavers = patio sq ft × pavers per sq ft × (1 + extra%)
Extra: 5% straight layout, 10% curves, diagonals or patterns
Sizes are nominal. Joints of about ⅛ in are small enough that the extra allowance covers them; for pavers with wide joints (such as 12 × 12 with ½ in gaps), add the gap to each dimension. Buy all pavers from one lot, since color varies between batches, and keep a few spares for future repairs.
Don’t forget the base and sand
A paver patio sits on 4 in of compacted gravel (6 in or more for driveways) and 1 in of bedding sand. See sand and gravel for pavers, or put your patio into the paver calculator to get pavers, base and sand together, with a bags-vs-bulk verdict for each. For sand alone, use the sand calculator.
