Paver Calculator

Calculate how many pavers you need for a patio, walkway, or driveway. Enter area dimensions and paver size to get paver count with waste allowance.

ft

Length of the patio, walkway, or driveway.

ft

Width of the area to pave.

in

Length of one paver. Common: 4", 6", 8", 12", 16", 24".

in

Width of one paver. Common: 4", 6", 8", 12", 16", 24".

%

Extra for cuts, breakage, edges. Straight-lay: 10%. Diagonal/herringbone: 15%.

How this calculator works

This paver calculator estimates paver quantity in three steps:

  1. Area: area length × area width (sq ft).
  2. Paver area: (paver length × paver width) / 144 to convert sq in to sq ft.
  3. Pavers needed: ceil(area / paver area), then add waste (default 10%).

The calculator also shows pavers per square foot, which helps estimate material cost quickly.

Formula

area          = area_length × area_width  (sq ft)
paver_area_in = paver_length × paver_width  (sq in)
paver_area    = paver_area_in / 144  (sq ft)
pavers_needed = ceil(area / paver_area)
pavers_waste  = ceil(pavers_needed × (1 + waste_pct / 100))

Example

For a 12 × 10 ft patio (120 sq ft) with 4×8 inch brick pavers, 10% waste:

  • paver_area = (4 × 8) / 144 = 0.222 sq ft
  • pavers_needed = ceil(120 / 0.222) = 541 pavers
  • pavers_with_waste = ceil(541 × 1.10) = 596 pavers

Important assumptions

  • Paver dimensions are NOMINAL — actual size is typically 1/8" smaller. The calculator uses your entered dimensions.
  • Standard waste: 10% for straight-lay, 15% for diagonal/herringbone, 20% for circles or curves.
  • Base material (gravel + sand) is calculated separately — use the Gravel Calculator for base material.
  • Pavers are often sold by the pallet (100-500 pavers depending on size). Check with your supplier.

FAQ

How many pavers do I need for a 10×10 patio?
A 10×10 patio (100 sq ft) with 4×8 brick pavers (0.222 sq ft each) needs ceil(100/0.222) = 451 pavers. With 10% waste: 497 pavers.
How much waste should I add for pavers?
10% for straight-lay patterns, 15% for diagonal or herringbone, 20% for circles or curves. Always order extra — paver dye-lots vary between batches.
How do I calculate pavers per square foot?
Divide 1 by the paver's area in sq ft. A 4×8 paver = 0.222 sq ft → 1/0.222 = 4.5 pavers per sq ft. A 12×12 paver = 1.0 sq ft → 1 paver per sq ft.
What about base material under the pavers?
You need 4-6 inches of gravel base plus 1 inch of sand. Use the Gravel Calculator for base material volume and weight.
