Concrete, Brick & Masonry calculator
Paver Calculator
Estimate whole pavers from project area, paver size and a cutting/breakage allowance.
Estimate whole pavers from project area, paver size and a cutting/breakage allowance. Keep the dimensions and units consistent, then check the figures that describe the product or layout you will really use. In this calculation, paver size and cut waste can change the answer materially. Use the installed module size or manufacturer coverage rather than nominal stone dimensions alone. Curves, borders and diagonal cuts can increase the number of pavers required.
What you need to enter
The Paver Calculator uses the following project information to calculate the result.
- Project area
- Paver length
- Paver width
- Waste (%)
Calculator result
Pavers / slabs required
How the Paver Calculator works
To produce pavers / slabs required, the Paver Calculator applies project area with waste ÷ paver area. The engine is configured for paver quantity for a patio, path or paved area, not as a generic text estimate. Check paver size and cut waste, since an incorrect value there can materially change the result.
Paver Calculator worked example
Paver Calculator example: a 24 m² path using 400 × 400 mm pavers needs 150 units before waste. Adding 8% for cuts and breakage raises the planning quantity to 162 whole pavers. The worked figure becomes more useful when paver size and cut waste is taken from the real product or site rather than a generic default.
Important calculation assumptions
For paver quantity for a patio, path or paved area, use the installed module size or manufacturer coverage rather than nominal stone dimensions alone. Curves, borders and diagonal cuts can increase the number of pavers required.
Frequently asked questions
What are the essential inputs for the Paver Calculator?
Measure the paved area and the actual paver/slab face dimensions, then add waste for cuts and pattern layout. On this page, the measurements are used specifically for paver quantity for a patio, path or paved area.
How should I handle paver size and cut waste in the Paver Calculator?
Before relying on the Paver Calculator, check paver size and cut waste. Use the installed module size or manufacturer coverage rather than nominal stone dimensions alone. Curves, borders and diagonal cuts can increase the number of pavers required.
Should I order exactly the amount shown by the Paver Calculator?
For the Paver Calculator, use the result in context: round up to whole pavers/slabs and allow for the pattern, edge cuts and breakage. Keep matching spares where colour or batch variation could matter.
