Paver Calculator

Estimate pavers for a patio or walkway from project dimensions, paver size, and a waste factor.

Assumptions

  • The patio or walkway is treated as a rectangle.
  • Base gravel, bedding sand, edge restraint, and joint sand are not included.
  • Pattern cuts and border pieces should be covered with a waste factor.
  • If your pavers are sold by the box or pallet, divide the result by the package quantity or coverage and round up.
  • Increase waste for diagonal, running-bond, curved, or bordered layouts.
  • Any cost estimate uses only the unit price you enter. No store or local price data is used.

Formula

  1. Patio area = patio length x patio width.
  2. Paver area = paver width x paver height converted to square feet.
  3. Pavers needed = ceil(patio area / paver area).
  4. Pavers including waste = ceil(pavers needed x (1 + waste factor)).

Example calculation

Example: 10 x 10 patio

A 10 ft by 10 ft patio using 12 in by 12 in pavers needs 100 pavers before waste and 105 pavers with 5% waste.

Common mistakes

  • Forgetting base gravel and bedding sand are separate materials.
  • Using nominal paver size when the actual size differs.
  • Not increasing waste for diagonal or running-bond patterns.

FAQ

Does this include paver base?

No. It estimates paver units only. Use the gravel calculator for base material.

Can I enter rectangular pavers?

Yes. Enter the paver width and height in inches.
