Paver Calculator
To calculate how many pavers you need, divide your project area in square feet by the area of one paver in square feet, then multiply by your waste factor. A 200-square-foot patio using 4×8-inch pavers needs approximately 920 pavers at 5% waste—order from a single production run to ensure color consistency.

How to Use This Paver Calculator
Enter your project length and width in feet, then select your paver size from the seven standard options (or enter a custom size). Choose the laying pattern that matches your design — the calculator automatically applies the correct waste factor, from 5% for running bond up to 20% for circular patterns.
Next, select your project type — patio/walkway, light vehicular driveway, or heavy vehicular driveway — to load the ICPI Tech Spec 4 compacted base depth for your application. The calculator returns the paver order count, gravel base in cubic yards and tons, ASTM C33 bedding sand in 60-lb bags, and polymeric sand in 50-lb bags based on your selected joint width.
All quantities include the appropriate waste and overlap allowances. Round up when purchasing materials — returning surplus is far cheaper than a second delivery charge.
How Many Pavers Do I Need?
Enter your project length and width, select your paver size, and choose your laying pattern. The calculator multiplies your area by the paver coverage rate and applies a pattern-specific waste factor — 5% for running bond, 15% for 45° herringbone. Round up to the nearest full paver; partial pavers cannot be returned.
A 10 × 10 ft residential patio at 100 square feet, laid in running bond with the most common 4 × 8-inch paver, works out to 115 pavers including a 5% waste factor. The same 100 square feet in 45° herringbone needs 132 pavers because diagonal cuts on every border edge waste more material.
The calculator returns the field count, the waste-adjusted order count, and a per-pallet rounding so your supplier can pull from one production batch. Color variation between production batches can be visible after installation — always order from the same run.
How to Calculate Pavers per Square Foot
Divide 144 (square inches in one square foot) by the individual paver's area in square inches. A 4×8-inch paver covers 32 sq in, so 144 ÷ 32 = 4.5 pavers per square foot. A 12×12-inch paver covers 144 sq in, giving exactly 1.0 pavers per square foot.
Worked example — 12 × 15 ft patio with 4 × 8-inch pavers in running bond
Inputs: L = 12 ft, W = 15 ft, paver = 4 × 8 in, pattern = running bond (5%)
Step 1. Area = 12 × 15 = 180 sq ft
Step 2. Paver area = 4 × 8 = 32 sq in → 32 ÷ 144 = 0.222 sq ft / paver
Step 3. Field count = ⌈180 ÷ 0.222⌉ = 811 pavers
Step 4. Order at 5% waste = ⌈811 × 1.05⌉ = 852 pavers
For irregular project shapes, measure the total area in square feet first using the square footage calculator — it handles L-shapes, triangles, and circles — then enter the total here.
Waste Factor by Pattern — How Much Extra Do You Need?
Waste factor accounts for edge cuts, breakage, and pattern-driven offcuts. Use 5% for straight running bond, 10% for 90° herringbone, and 15% for 45° herringbone. Always order extra from the same production batch; color variation between batches can be visible after installation.
| Pattern | Waste Factor | Geometric Reason |
|---|---|---|
| Running bond (90°) | 5% | Minimal cuts; mostly straight edges. |
| Stack bond | 5% | Grid layout; minimal cuts. |
| Basket weave | 7% | Paired cuts at border transitions. |
| Herringbone 90° | 10% | More edge cuts per linear foot of border. |
| Herringbone 45° (diagonal) | 15% | Diagonal cuts on all four borders; triangular offcuts are non-reusable. |
| Circular / fan | 20% | High custom-radius cut percentage. |

For indoor tile projects or outdoor ceramic tile surfaces, the tile calculator handles the same area-plus-waste logic.
Paver Sizes, Coverage Rates, and Pavers per Square Foot
Common concrete paver sizes range from 3⅞ × 7⅞ inch (standard brick paver) to 23⅝ × 23⅝ inch (large-format slab). Smaller pavers distribute load across more joints, making them better for driveways. Larger-format pavers suit patios where fewer joints means less polymeric sand and a cleaner visual finish.
| Size | Dimensions (in) | Area (sq in) | Pavers/Sq Ft | Typical Use |
|---|---|---|---|---|
| Standard Brick | 3⅞" × 7⅞" | 30.5 | 4.72 | Walkways, accent borders |
| Holland 4×8 | 4" × 8" | 32 | 4.50 | Patios, walkways, light driveways |
| 6×6 | 6" × 6" | 36 | 4.00 | Patios, accents |
| 6×9 | 6" × 9" | 54 | 2.67 | Driveways, herringbone driveways |
| 12×12 | 12" × 12" | 144 | 1.00 | Patios, pool decks |
| 12×24 | 12" × 24" | 288 | 0.50 | Large-format patios, pool decks |
| Large-Format Slab | 23⅝" × 23⅝" | 558 | 0.258 | Pedestrian-only patios, pool decks |

How Much Base Material Do I Need?
Paver projects require a compacted aggregate base, a 1-inch bedding sand layer, and — on clay soils — a geotextile separator fabric. Base depth depends on application: 4 inches compacted for pedestrian patios, 6 inches for light vehicles, 8 inches for heavy vehicles, per ICPI Tech Spec 4. Ninety percent of paver failures originate from an under-built base.
| Project Type | Compacted Base | ICPI Reference | Notes |
|---|---|---|---|
| Patio / walkway (pedestrian) | 4 in | ICPI Tech Spec 4 §4.2 | Add 2 in in deep-frost zones (frost line > 36 in). |
| Light vehicular driveway | 6 in | ICPI Tech Spec 4 §4.3 | Cars and light trucks under 6,000 lb GVW. |
| Heavy vehicular driveway | 8–12 in | ICPI Tech Spec 4 §4.4 | RVs, boats, delivery trucks; consult a PE for over 12 in. |
Bedding Sand Layer — Always ASTM C33
The bedding sand layer is exactly 1 inch nominal, never more than 1.5 inches per ICPI Tech Spec 17. Specify ASTM C33 coarse concrete sand by name on the delivery ticket. For the 1-inch bedding sand layer between your compacted base and your pavers, the sand calculator converts square footage and depth into bags or cubic yards.
Expert note · Marcus Johnson, CCM
On clay soils, skipping geotextile fabric is the fastest way to watch a paver patio turn into a wavy mess in year two. I have re-built patios where the homeowner saved $40 on fabric and spent $3,000 on a reset.
How Many Bags of Polymeric Sand Do I Need?
Polymeric sand fills the joints between pavers, locking them and blocking weeds. Coverage is 25–50 square feet per 50-pound bag, depending on joint width and paver thickness. For a standard 200-square-foot patio with 3/16-inch joints, plan on 6–8 bags. Sweep dry into joints, then mist to activate the binding agent.
3/16" joint (narrow)
~50 sq ft/bag
Thin pavers, tight patterns
1/4" joint (standard)
~40 sq ft/bag
Most residential applications
3/8" joint (wide)
~25 sq ft/bag
Thick pavers, wider spacing
Application is dry-sweep, blow off the excess, then mist — not soak. Wet pavers cause haze that is hard to remove; the polymeric sand manufacturers (Techniseal, Alliance Gator, Sakrete) all warn against application after rain or onto damp pavers in their 2026 product data sheets.
How Many Pavers Come on a Pallet?
Most concrete paver pallets cover 100–160 square feet depending on paver size and manufacturer. Divide your total paver count by the pallet quantity listed on the supplier's data sheet to get pallets needed — always round up. Ordering by the full pallet is typically cheaper per square foot than ordering by the piece.
When ordering by the pallet, order one full extra pallet beyond the calculated need. The reason is color consistency: paver suppliers run production batches and shift dye lots between runs. A spare pallet from the same run is your only guarantee that a future repair will match the original installation. Two years from now, the same SKU pulled from a fresh batch will be visibly different in the sunlight.
What Does It Cost to Install Pavers? (2026)
Installed paver patio cost averages $12–$30 per square foot in 2026, including materials and labor. Concrete pavers cost $4–$6 per square foot for materials alone; natural stone runs $7–$16 per square foot. A 200-square-foot patio costs $2,400–$6,000 installed. Complex patterns, steep grades, and high-end materials push costs toward the upper range.
| Material Type | Materials (per sq ft) | Installed Range | Notes |
|---|---|---|---|
| Concrete paver | $4–$6 | $12–$22 | Most common residential choice; widest color/size selection. |
| Brick paver (clay) | $5–$8 | $14–$24 | Classic look; tighter joint pattern; +10% labor over concrete. |
| Natural stone (flagstone) | $7–$13 | $18–$28 | Irregular shapes drive labor; 20% waste typical. |
| Travertine | $8–$16 | $20–$30 | Pool decks; sealed annually; +15% labor over concrete. |
| Large-format slab | $10–$18 | $22–$32 | Fewer joints; specialty install crew premium. |
