Paver Calculator

Plan a paver patio, walkway or driveway. Enter the area and paver size to get the number of pavers, the gravel base in cubic yards and tons, and the bedding sand.

How this calculator works

The number of pavers is the area divided by the area of one paver (length × width ÷ 144 to convert square inches to square feet), plus extra for cuts.

Pavers sit on a compacted gravel base, usually 4 inches for patios and 6–8 inches for driveways, topped with about 1 inch of bedding sand.

Base and sand volumes are the area multiplied by each depth, converted to cubic yards. Gravel weight assumes about 1.4 tons per cubic yard.

Example: a 10 × 10 ft patio with 4 × 8 in pavers

  1. Paver area: 4 × 8 ÷ 144 = 0.222 sq ft.
  2. Pavers: 100 ÷ 0.222 = 450, plus 5% = 473 pavers.
  3. Gravel base (4 in): 100 × 0.333 = 33.3 cu ft = 1.23 cu yd ≈ 1.73 tons.
  4. Bedding sand (1 in): 100 × 0.083 = 8.3 cu ft = 0.31 cu yd.

Tips before you buy

  • Herringbone and circular patterns need 10–15% extra because of the angled cuts.
  • Compact the gravel base in 2 inch layers with a plate compactor for a patio that will not sink.
  • Use polymeric sand in the joints to lock pavers in place and reduce weeds.

Frequently asked questions

How many pavers do I need for a 10 × 10 patio?

With standard 4 × 8 inch pavers you need 450 pavers for 100 square feet, or about 473 with 5% extra for cuts.

How much gravel do I need under pavers?

For a 4 inch base, multiply the area in square feet by 0.333 to get cubic feet, then divide by 27. A 10 × 10 ft patio needs about 1.23 cubic yards.

How deep should the sand be under pavers?

About 1 inch of coarse bedding sand over the compacted base. Thicker sand layers can shift and cause uneven pavers.
