How is paver/brick quantity calculated?

Total area divided by a single paver's surface area, accounting for joint spacing.

How much extra should I order?

Commonly 5-10% extra for simple layouts, more for complex patterns.

Does pattern affect material needed?

Yes — intricate patterns like herringbone require more cutting and waste.

What Is a Paver & Brick Calculator?

This calculator estimates how many pavers, bricks, or patio stones you need to cover a patio, walkway, or driveway. It divides the total area by the footprint of a single paver, then adds an allowance for cuts and breakage — the small waste percentage professionals always budget for.

A staggered brick-laying pattern — the calculator estimates units for the whole area.

Formula

Area (sq ft) = Length × Width
Paver Area (sq ft) = (Paver Length × Paver Width) ÷ 144
Pavers Needed = (Area ÷ Paver Area) × (1 + Waste %)

How to Use This Calculator

Enter the length and width of the area you're paving, in feet.
Enter the size of a single paver or brick, in inches.
Enter a waste allowance — 10% is typical for a straightforward rectangular layout, more for complex patterns or curves.
Click "Calculate Pavers Needed" for the total area and the number of units to buy.

Worked Example

Example: A 20 ft × 10 ft patio (200 sq ft) using 12×6 in pavers (0.5 sq ft each), with 10% waste: Pavers = (200 ÷ 0.5) × 1.10 = 440 pavers.
