Paver Calculator
Estimate patio pavers from area, paver dimensions, and waste.
This paver calculator estimates how many pavers are needed for a patio or walkway, based on the project area, individual paver size, and a waste allowance for cutting around edges and curves.
Enter your project area and paver dimensions, and the calculator returns the total number of pavers needed.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 200 sq ft patio, 1 sq ft pavers, 8% waste | 216 pavers | Pavers = (200 ÷ 1) × 1.08 = 216. |
| 150 sq ft patio (herringbone), 0.5 sq ft pavers, 15% waste | 345 pavers | Pavers = (150 ÷ 0.5) × 1.15 = 300 × 1.15 = 345. |
Calculating Paver Quantity
Pavers needed = (project area / area of one paver) x (1 + waste percentage). For example, a 200 sq ft patio using 1 sq ft pavers needs approximately 200 pavers before waste, with an added 5-10% commonly included for cuts and pattern fitting.
Why Pattern Choice Affects Waste
A simple grid or running-bond pattern typically produces less waste than more complex patterns like herringbone, since intricate patterns require more edge cuts to fit the project's border - choosing a higher waste allowance for complex patterns helps avoid running short mid-installation.

Frequently Asked Questions
How do you calculate how many pavers you need?
Divide the total project area by the area of a single paver, then add a waste allowance (commonly 5-10%) to account for cuts along edges and curves.
Do complex paver patterns need more waste allowance?
Yes - patterns like herringbone typically require more cutting to fit project edges than a simple grid pattern, so a higher waste percentage (sometimes 10-15%) is often recommended for more intricate layouts.
Should I order extra pavers beyond the exact calculation?
Yes - beyond the waste allowance for cuts, ordering a few extra pavers is generally recommended in case of future repairs, since paver colors and styles can be discontinued over time, making later matching difficult.

What does the Paver Calculator calculate?
Estimate patio pavers from area, paver dimensions, and waste. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this paver use?
The formula is: pavers = project area / paver area * (1 + waste). Concrete pavers became a mainstream residential landscaping material in North America starting in the 1970s and 1980s, adapted from European interlocking-paver systems developed decades earlier - the waste allowance in this formula scales up for more intricate laying patterns like herringbone, which require more edge cutting than a simple running-bond pattern.
