How Many Pavers Do You Need? The Short Answer
Every paver estimate starts with two numbers: the area you are paving, and the footprint of one paver. Keep both in the same units and the math is one division. In square feet it looks like this:
Pavers per square foot = 144 / (paver length in inches x paver width in inches)
The 144 is just the number of square inches in a square foot. A 4x8 inch paver covers 32 square inches, so 144 / 32 = 4.5 pavers per square foot. A 12x12 inch paver is exactly 1 per square foot. Multiply by your total area, add a waste factor for cuts and breakage, and you have your order quantity. The calculator above applies this to rectangles, circles, multi-section shapes, and plain square footage, with metric units supported too.
Worked Example: A 12 by 16 Foot Patio
Say you are paving a 12 by 16 foot patio with standard 4x8 inch brick pavers, 1/8 inch joints, and a 10% waste allowance. Here is every step, exactly as the calculator does it:
| Step | Math | Result |
| Project area | 12 ft x 16 ft | 192 sq ft |
| Pavers per sq ft | 144 / (4 x 8) | 4.5 |
| Pavers for coverage | 192 x 4.5 | 864 |
| Add 10% waste | 864 x 1.10, rounded up | 951 pavers |
| Pallets (110 sq ft each) | 951 / 495 per pallet | 2 pallets |
| Base gravel, 4 in + 20% compaction | 192 x (4/12) / 27 x 1.2 | 2.84 cu yd (about 4.0 tons) |
| Bedding sand, 1 in | 192 x (1/12) = 16 cu ft | 0.59 cu yd, 32 fifty-lb bags |
| Polymeric joint sand | 9.77 cubic in of joints per sq ft | 3 fifty-lb bags |
| Edge restraint | 2 x (12 + 16) | 56 linear ft |
At $0.75 per paver, $45 per cubic yard of gravel, $6 per bag of bedding sand, and $30 per bag of polymeric sand, materials come to about $1,123. Add professional installation at $12 per square foot ($2,304) and the full project lands near $3,427. Every price on the calculator is editable, so plug in your supplier quotes for a truer number.
Paver Size Coverage Table
Paver size is the single biggest driver of your order count. Smaller pavers mean far more pieces, more joints, and more joint sand, even though the base and bedding stay the same. These are exact coverage counts before waste:
| Paver size | Area each | Per sq ft | Per 100 sq ft |
| 4 x 8 in (standard brick) | 0.22 sq ft | 4.5 | 450 |
| 6 x 6 in | 0.25 sq ft | 4.0 | 400 |
| 6 x 9 in | 0.38 sq ft | 2.67 | 267 |
| 8 x 8 in | 0.44 sq ft | 2.25 | 225 |
| 12 x 12 in | 1.00 sq ft | 1.0 | 100 |
| 12 x 18 in | 1.50 sq ft | 0.67 | 67 |
| 24 x 24 in | 4.00 sq ft | 0.25 | 25 |
What Goes Under the Pavers: Base, Sand, and Joints
Pavers are the part you see, but the base decides whether the patio stays flat for ten years or starts rocking after two winters. The standard build is three layers. First, 4 to 6 inches of compacted crushed gravel for a patio or walkway, or 6 to 8 inches for a driveway, compacted in thin lifts with a plate compactor. Crushed stone settles under compaction, so the calculator adds 20% extra volume by default. Second, a true 1 inch of coarse bedding sand, screeded flat as a setting bed, not piled up to fix a bad base. Third, the pavers themselves, with polymeric sand swept into the joints and misted with water so it hardens and locks everything together.
Polymeric sand is the one material people underestimate, because it fills a volume rather than covering an area. With 4x8 inch pavers and tight 1/8 inch joints, one 50 lb bag covers about 85 to 90 square feet, but with 1/4 inch joints the same bag covers only about 45 square feet. This calculator estimates bags from your actual paver size, joint width, and joint depth instead of a flat coverage rule. To double check base stone tonnage against supplier quotes, run the same area through our gravel calculator.
Patterns and Waste: Why the Layout Changes Your Order
The pattern you lay decides how many pavers get cut. A running bond, stack bond, or basketweave on a square patio produces few offcuts, so 5% waste is plenty. A 90 degree herringbone forces cuts along every angled edge, so use 10%. A 45 degree herringbone, a diagonal layout, or anything curved turns many edge pieces into unusable triangles, and that is where the 15% figure comes from. The calculator sets the waste automatically when you pick a pattern, and you can override it with any custom value. One rule matters more than the exact percentage: order everything, waste included, from a single production batch, because pavers vary slightly in color between runs. For indoor work the math is nearly identical; our floor tile calculator handles the indoor version.
How Much Does a Paver Project Cost?
Paver cost has two halves: materials and installation. Concrete pavers run $3 to $8 per square foot for materials, while natural stone can reach $15 to $30. Professional installation adds $8 to $25 per square foot depending on pattern complexity, site access, and excavation. A 200 sq ft patio therefore lands around $2,000 to $5,000 installed.
| Cost item | Typical 2026 range |
| Concrete pavers (materials) | $3 to $8 per sq ft |
| Base gravel + bedding sand | $1 to $3 per sq ft |
| Polymeric joint sand | $25 to $40 per 50 lb bag |
| Edge restraint | $1 to $2 per linear ft |
| Installed paver patio | $10 to $25 per sq ft |
Doing it yourself saves the labor, but base prep is the make-or-break part: excavation, grading, and compaction decide whether the patio survives its first winter. Collect two or three local quotes and compare them against the material estimate above. If the new patio sits inside a yard you plan to fence, price that at the same time with our fence calculator, since contractors often discount combined jobs.
How to Use This Calculator
Pick imperial or metric units, then choose your project type so the base depth defaults correctly. Enter the area as a rectangle, a circle, several sections for L shapes, or plain square footage. Pick your paver size or enter custom dimensions, set the joint width and depth, choose a pattern so the right waste percentage applies, and adjust the base depth if your soil demands more. Enter your supplier prices to get the paver count with coverage and spare broken out, pallets, base gravel in cubic yards and tons, bedding sand, polymeric joint sand bags, edge restraint length, and a full cost breakdown.
Frequently Asked Questions
How many pavers do I need per square foot?
Divide 144 by the paver's length times width in inches. A 4x8 inch paver covers 32 square inches, so 144 / 32 = 4.5 pavers per square foot. A 6x9 inch paver takes about 2.67 per square foot, and a 12x12 inch paver takes exactly 1. Multiply by your area and add 5 to 15% for cuts.
What waste percentage should I add for pavers?
Use 5% for running bond, stack bond, or basketweave, 10% for 90 degree herringbone, and 15% for 45 degree herringbone, diagonal, or curved layouts. Always order the extra from the same production batch so the color matches your field.
How deep should the base be for a patio versus a driveway?
A patio or walkway needs 4 to 6 inches of compacted crushed gravel with a 1 inch bedding sand layer on top. A driveway needs 6 to 8 inches of gravel, and weak or wet soil can call for up to 10 inches. The bedding sand stays at 1 inch in every case.
How many bags of polymeric sand do I need?
It depends on paver size and joint width, not just area. For 4x8 inch pavers with tight 1/8 inch joints, a 50 lb bag covers about 85 to 90 square feet, but with 1/4 inch joints the same bag covers only about 45 square feet. The calculator above estimates bags from your actual joint volume, so round up and keep one sealed bag for future repairs.
Do I need edge restraint for a paver patio?
Yes. A spiked plastic or metal edge restraint along the perimeter keeps the outer pavers from spreading, which is what eventually loosens the whole field. Measure the perimeter (2 x length + 2 x width for a rectangle); the calculator estimates it for you from your area inputs.
