Calculate the area
Length × width gives the paved area. Curves and L-shapes should be divided into measurable sections.

Paving quantities
Measure before you order
Use the actual paver dimensions. Split irregular or curved areas into simple rectangles and add the results.
02
The method
How the estimate works
Each output shows its assumptions so you can replace defaults with the dimensions, pack sizes and rates available to you.
Count actual units
The area is divided by one paver's face area, then the selected cutting and breakage allowance is added.
Build the layers
Bedding and base-course volumes use your chosen depths. Loose base includes a 15% compaction allowance.
Confirm the site
CMA guidance calls for drainage checks, a prepared base and edge restraints.
Important boundary
A paver count is not a pavement design.
Expansive soil, vehicle loads, falls, underground services, drainage and compaction can change the required excavation and base construction.

Questions homeowners ask
How many 200 × 100 mm pavers are needed per square metre?+
The clean mathematical count is 50 pavers per m² before joints and waste. Order from the supplier's stated coverage and include cutting and breakage.
How much extra paving should I order?+
The Concrete Manufacturers Association advises adding 10% for cutting and wastage. Complex curves or diagonal patterns may need a larger allowance.
How much bedding sand is needed?+
CMA guidance uses about 2.5 m³ per 100 m², equivalent to a 25 mm uncompacted layer. Confirm the specification for your system.
Can I lay pavers without edge restraints?+
No. Edge restraints prevent the paved field from spreading and losing interlock; existing walls may act as restraints where suitable.
