How to Use This Calculator
Enter your input values
Fill in all required input fields for the Paver Calculator. Most fields include unit selectors so you can work in your preferred unit system — metric or imperial, whichever matches your problem.
Review your inputs
Double-check that all values are correct and that you have selected the right units for each field. Incorrect units are the most common source of calculation errors and can produce results that are off by factors of 2, 10, or more.
Read the results
The Paver Calculator instantly computes the output and displays results with units clearly labeled. All calculations happen in your browser — no loading time and no data sent to a server.
Explore parameter sensitivity
Try adjusting individual input values to see how the output changes. This is a quick and effective way to develop intuition about how different parameters influence the result and to identify which inputs have the largest effect.

About Paver Calculator
Brick pavers and concrete pavers are popular choices for patios, walkways, driveways, and pool decks because they offer durability, beauty, and ease of repair compared to poured concrete. Ordering the correct quantity requires converting your project area into the number of individual pavers, accounting for a waste factor that covers cutting, breakage, and future replacement stock. This calculator divides the project area by the area of a single paver and applies a waste percentage to determine the total order quantity. Standard rectangular pavers range from 4x8 inches to 12x12 inches, but many manufacturers offer interlocking, tumbled, and modular patterns in various dimensions. A 10 percent waste factor is appropriate for rectangular layouts with straight edges, while curved borders and complex patterns require 15 percent or more because more cuts mean more unusable offcuts.
The Math Behind It
Formula Reference
Paver Count Formula
Pavers = Area / (Paver L x W / 144) x (1 + Waste%)
Variables: Area in sq ft; Paver dimensions in inches; 144 converts sq in to sq ft.
Worked Examples
Example 1: Standard patio with 4x8 pavers
200 sq ft patio, 4x8 inch pavers, 10% waste for straight edges.
Order 990 pavers for the 200 sq ft patio.
Example 2: Curved walkway with 12x12 pavers
80 sq ft curved walkway, 12x12 inch pavers, 15% waste for curves.
Order 92 pavers for the curved walkway.
Common Mistakes & Tips
- !Not ordering enough extra pavers for future repairs -- always keep 5-10 percent as spares because matching pavers from a different production lot is nearly impossible.
- !Using only 5% waste for a project with curves or angles, which almost always results in running short and delaying the project.
- !Forgetting to account for the joint spacing between pavers, which slightly reduces the number of pavers per square foot -- for most pavers with 1/8-inch joints, the difference is only 2-3 percent.

Frequently Asked Questions
How many pavers do I need per square foot?
The number depends on paver size: 4x8 inch pavers require about 4.5 per sq ft; 6x6 inch pavers need 4 per sq ft; 6x9 inch pavers need 2.67 per sq ft; and 12x12 inch pavers need 1 per sq ft. These counts assume tight joints; wider joints slightly reduce the count.
What base thickness do I need under pavers?
For pedestrian areas (patios, walkways), 4-6 inches of compacted crushed stone base is standard. For vehicular areas (driveways), 8-12 inches of compacted base is recommended. The base should be compacted in 2-4 inch lifts to achieve at least 95 percent Proctor density. Above the base, a 1-inch layer of bedding sand provides the final level surface for paver placement.
Do I need edging for pavers?
Yes, edge restraint is critical to prevent pavers from shifting and spreading over time. Without edging, the pavers along the perimeter gradually move outward, opening joints and destabilizing the entire surface. Plastic paver edging, aluminum edging, concrete borders, or existing structures (foundation walls, curbs) all serve as effective edge restraint.
