Paver Calculator

This calculator counts the pavers needed to cover a patio, path or driveway. It accounts for the joint between pavers and adds a waste allowance for cuts along edges and around curves.

Gap between pavers, often 1/16–3/16 in (2–5 mm). Many pavers have built-in spacer nubs.

Material & assumptions
%

5–10% for straight patterns; 15% or more for herringbone, diagonal layouts or many curves.

How the calculation works

  • Pavers = Area ÷ ((Paver length + Joint) × (Paver width + Joint))
  • Total = Pavers × (1 + Waste %), rounded up

Adding the joint width to each paver dimension gives the area each paver actually occupies once laid.

Assumptions used

  • The calculation uses a uniform paver size.
  • Waste depends on pattern: 5–10% straight, 15%+ herringbone or diagonal.

Example calculation

A 10 × 10 ft patio using 8 × 4 in pavers with no joint gap and 10% waste.

  1. 1Area: 100 ft² = 14,400 in²
  2. 2Each paver: 8 × 4 = 32 in²
  3. 3Pavers: 14,400 ÷ 32 = 450
  4. 4With 10% waste: 495 pavers

Result: Buy 495 pavers.

How to measure your project

  • Measure the area to be paved after edge restraints are planned.
  • Use the actual paver dimensions from the product sheet; many are slightly smaller than their nominal size.
  • For mixed-size paver kits, use the coverage per pallet or per square foot from the manufacturer instead.

Frequently asked questions

How many pavers are in a square foot?

It depends on size: 4.5 standard 4 × 8 in pavers, 1 paver of 12 × 12 in, or 0.44 pavers of 18 × 18 in, ignoring joints.

How much extra paver should I buy?

Add 5–10% for simple rectangular layouts and 15% or more for herringbone, circles or lots of curves. Keep spares for future repairs.
