Paver Calculator: Count from Installed Face Size

Estimate paver count from area, installed face dimensions, and waste.

Enter the installed face size for the exact paver and keep base design outside the count.

Enter the measured finished paved area.

Enter the installed face length of one paver.

Enter the installed face width of one paver.

Enter an allowance appropriate to the pattern and cuts.

Estimate boundary

What this result covers

  • Estimates paver count only and does not design base, bedding, joints, drainage, compaction, edge restraint, slope, or load capacity.
  • Use the result as a purchasing estimate and verify product instructions, site conditions, and local requirements before work begins.

How the calculation works

Formula

area × (1 + waste percentage) × 144 ÷ (paver face length × paver face width)

Assumptions used

  • Entered paver dimensions describe installed face area.

The tool keeps user-entered product values separate from the geometry, then rounds the recommended purchasing quantity up where the material is bought as a whole unit.

Worked example

Project inputs
200 ft², 8 in × 4 in pavers, 10% waste
Purchase result
990 pavers after rounding up.

Enter these values in the calculator to reproduce the estimate. The purchase result uses the same tested calculation logic as the live tool.

Purchasing checklist

  1. Confirm paver dimensions and pattern.
  2. Obtain a site-specific base design.
  3. Plan bedding, joints, and edge restraint separately.

Common mistakes

  • Using package dimensions instead of face size.
  • Assuming one base depth fits every site.
  • Ignoring pattern cuts.

    Base depth is site/design dependent; guide uses nominal 1-inch bedding and 4–8 inches or more of base.
