How a paver patio is built, and calculated

A paver patio is three layers: compacted gravel base, a 1-inch bed of sand, then the pavers. Each layer is ordered separately.

Pavers = area × (1 + waste %) ÷ area of one paver
Base gravel (cu yd) = area × depth (in) ÷ 12 ÷ 27 × 1.10
Sand (cu yd) = area × 1 in ÷ 12 ÷ 27

The extra 10% on gravel covers the volume lost when it’s compacted.

Worked example: a 16 × 12 ft patio in 4 × 8 pavers

192 sq ft plus 10% waste is 211 sq ft. Each 4 × 8 paver covers 0.222 sq ft, so you need 951 pavers. A 4-inch base takes 2.6 cubic yards of gravel (about 3.7 tons) and the sand bed 0.6 yards. DIY materials come to about $1,100; a pro would charge roughly $1,500–$4,600.

Frequently asked questions

How deep should the base be?

4–6 inches for patios and walkways, 8–12 inches for driveways. Clay soil and cold climates need the deeper end.

How many pavers are in a square foot?

4.5 for 4 × 8 pavers, 4 for 6 × 6, 2.67 for 6 × 9, and 1 for 12 × 12.

Do I need edging?

Yes. Edge restraint keeps pavers from creeping outward. Plan for the full perimeter, except where the patio meets a wall.
