How to use the Paver / Patio Calculator

Estimate individual pavers and full packs for a rectangular patio or path, with waste, cost and an optional base-material volume.

Step by step

What to enter

Enter patio dimensions or reuse a saved outdoor space.
Enter the face dimensions of one paver.
Choose a waste allowance and enter how many pavers come in a pack or pallet.
Optionally add base depth and material price.

Method

How the calculation works

The project area is divided by the face area of one paver to estimate the base unit count. Waste is added for cuts, breakage and pattern layout.

The recommended count is rounded into full packs. If a base depth is entered, PlanCalq also calculates the approximate compacted base volume across the patio area.

Calculation summaryPatio area ÷ paver face area = pavers requiredRequired pavers × (1 + waste %) = recommended paversPatio area × base depth = approximate base volume

Worked example

Example: pavers for a 5 m × 4 m patio

Patio: 5 m × 4 m = 20 m²
Paver: 200 mm × 100 mm
Waste: 10%

Planning resultThe planning coverage becomes 22 m². A 0.02 m² paver footprint gives a theoretical order of about 1,100 pavers before pack rounding.

Paver quantity is based on surface coverage plus the chosen waste allowance. Pack or pallet rounding then turns that coverage into a purchasable quantity.

Interpret the output

How to read the result

The paver count covers the wearing surface; base material is a separate volume estimate.
Use a higher waste allowance for diagonal patterns, curves, borders or many small cuts.
Check whether supplier pack coverage is based on nominal dimensions including joints or exact unit dimensions.

Planning limits

What this calculator does not cover

Base thickness, drainage, edge restraint and compaction depend on site conditions and intended loads.
The calculator does not design a patio or driveway pavement structure.
Pattern-specific layouts can change cutting waste and border quantities.
