How Many Pavers Do I Need?
Estimating pavers starts with the total surface area of your patio, walkway or driveway. Once you know the area, paver dimensions and expected waste, you can estimate the number of individual pavers or full pallets you need.

Enter your project dimensions, paver size and waste allowance to estimate the quantity you need.
Use the Paver Calculator Square Footage CalculatorHow to Calculate Pavers
For a rectangular patio or walkway, begin with the surface area:
A 12 ft by 16 ft patio has an area of:
Next, determine how much area each paver covers.
How Much Area Does One Paver Cover?
If your paver dimensions are given in inches, convert them to feet before calculating square footage.
For a 12 in × 12 in paver:
A 6 in × 12 in paver covers:
Basic Paver Formula
For a 192 ft² patio using 1 ft² pavers:
This is the theoretical quantity before waste.
How Much Extra Should You Add?
Extra pavers help cover cuts, breakage and layout adjustments. A straightforward rectangular layout may use around 5% to 10% extra as a planning allowance.
Diagonal patterns, curves and complicated borders often require more.
| Layout | Planning Waste | Reason |
|---|---|---|
| Simple straight pattern | About 5% to 10% | Normal cuts and breakage |
| Diagonal layout | About 10% to 15% | More angled cuts |
| Curved patio | Often higher | More perimeter cutting |
| Complex pattern | Project-specific | Pattern matching and cuts |
Example With 10% Waste
Our 192 ft² patio requires 192 one-square-foot pavers before waste.
Round upward to approximately 212 pavers.
Common Paver Sizes
| Paver Size | Approx. Area | Approx. Pavers per 100 ft² |
|---|---|---|
| 6 in × 6 in | 0.25 ft² | 400 |
| 6 in × 12 in | 0.5 ft² | 200 |
| 12 in × 12 in | 1 ft² | 100 |
| 12 in × 18 in | 1.5 ft² | About 67 |
| 12 in × 24 in | 2 ft² | 50 |
Do Paver Joints Affect Quantity?
Joint width can affect layout, but the easiest purchasing method is usually to use the manufacturer's stated square-foot coverage per pallet, layer or package.
This is especially important for multi-size paver systems where several shapes are installed together in a repeating pattern.
How to Calculate Pavers for an Irregular Patio
Divide the project into simple shapes such as rectangles and squares.
- Calculate each section separately.
- Add the areas together.
- Calculate paver quantity from the total.
- Add your waste allowance.
How to Calculate Pavers for a Circular Patio
A circular patio with a radius of 8 ft has an area of approximately:
Add waste before converting that area into pavers.
Don't Forget the Paver Base
Pavers are only the visible surface. Many installations also require an aggregate base beneath them.
The amount depends on:
- Project area
- Base depth
- Soil conditions
- Expected loads
- Local installation practices
You can estimate aggregate volume using our Gravel Calculator.
What About Bedding Sand?
Many paver systems use a bedding layer above the compacted base. Thickness and material specifications vary by installation system.
Calculate bedding material separately from the pavers themselves.
Pavers for a Driveway vs Patio
A driveway supports vehicle loads, so base preparation and paver specifications can differ significantly from a pedestrian patio.
Use products approved for the intended load and follow the manufacturer's installation requirements.
Common Paver Calculation Mistakes
Using Inches as Feet
Convert paver dimensions correctly before calculating area.
Buying the Exact Quantity
Cutting and breakage normally create some waste.
Ignoring Pattern Waste
Diagonal and complex layouts can require more material.
Forgetting Borders
Border pavers may use a separate size or color and should be calculated separately.
Forgetting the Base
A paver count does not include gravel, bedding material or edge restraints.
Frequently Asked Questions
How do I calculate how many pavers I need?
Divide the total project area by the area covered by one paver, then add waste and round up.
How many 12 × 12 pavers cover 100 square feet?
A 12 in × 12 in paver covers approximately 1 ft², so the theoretical quantity is 100 pavers before waste.
How much extra paver material should I buy?
About 5% to 10% may be suitable for a simple layout, while diagonal, curved or complex designs may require more.
Do I need gravel under pavers?
Many paver installations use a compacted aggregate base, but the required material and depth depend on the project and installation system.
