Paver Patio Calculator

How many pavers to cover your patio or walkway.

How it is calculated

The patio area is length × width with both entered in feet, giving square feet. One paver covers (paver length ÷ 12) × (paver width ÷ 12) square feet, because paver sizes are entered in inches. The base count is the area divided by one paver's area, then the waste allowance is added: pavers = ceil(base × (1 + waste ÷ 100)). The result is rounded up to a whole paver; an exact result is kept as it is (100 pavers with 10% waste gives 110, not 111). The tool counts the paver faces only. It does not add joint width, so if your design has visible joints, use the paver size plus the joint, and it does not size the base gravel or sand. The area is shown in ft².

Worked example

A 12 ft × 10 ft patio with 6 in × 9 in pavers and 10% waste. Area: 12 × 10 = 120 ft². One paver: 0.5 ft × 0.75 ft = 0.375 ft². Base count: 120 ÷ 0.375 = 320 pavers. With 10% waste: 320 × 1.10 = 352. You need 352 pavers.

Common mistakes

  • Entering the patio length and width in inches or metres. They are read as feet, while the paver size is read in inches.
  • Entering the paver size in feet or centimetres. A 6 × 9 inch paver is typed as 6 and 9.
  • Setting waste to 0 for a diagonal or curved layout. Cuts along the edges and breakage mean you will run short; with 0% the tool gives exactly 320 here, no spare.
  • Ignoring joint spacing. The count assumes pavers touch, so wide joints make the true number of pavers slightly lower.
  • Forgetting to subtract an area that will not be paved, such as a planter or a fire pit.

About this calculator

This calculator divides the total patio or walkway area by the footprint of a single paver (its length × width) to get a base paver count, then adds a waste allowance — typically 5–10% for a simple rectangular layout, more for diagonal or curved patterns and cuts around edges — to account for breakage, trimming and pattern offsets.

DIY homeowners and landscapers use it before a materials run to avoid the common mistake of buying exactly the calculated count and running short mid-project once cut pieces and breakage are factored in, since most suppliers won't guarantee an exact dye-lot match on a second order placed later.

    A quick sanity check is pavers per square foot, which is 144 divided by length times width in inches. A 4 by 8 inch paver gives 4.5 per square foot, so a 12 by 10 foot patio needs 540 before waste and 594 with 10 percent. Compare the area shown with the coverage printed on a supplier's pallet. Did you lay a plain grid or a pattern, and how much waste did you actually need?
