Paver Calculator

Calculate the number of pavers needed for a patio or walkway based on area and paver size.

Pavers Needed
— pavers
Includes waste.

Usage Tip

Order a few extra from the same lot for repairs; dye lots vary, and a cracked paver years later is hard to match.

THE MATH
paver area = (width ÷ 12) × (length ÷ 12)
pavers = round up( area × (1 + waste ÷ 100) ÷ paver area )
The number of pavers is the patio area divided by each paver footprint, plus a waste allowance for cuts and breakage. A 12 by 12 inch paver covers one square foot.
Enter the area, the paver width and length in inches, and a waste percentage.
The result rounds up to whole pavers.
