Paver Calculator
Estimate paver quantity, sand, and gravel base needed for patios, walkways, and driveways. Supports various paver sizes and includes waste factor.
Paver patios and walkways have become the dominant high-end hardscape choice over poured concrete because pavers offer better aesthetics, easier repair (individual stones can be replaced if damaged), and dramatic design flexibility. A 200 sq ft paver patio costs $2000-4500 installed depending on paver type, vs. $1200-2500 for poured concrete — but lasts 30-50 years with minimal maintenance and supports limitless design options.
This calculator returns the number of individual pavers needed for a given area based on paver dimensions, plus accounts for waste factor (10% standard for straight installations, 15-20% for diagonal or pattern-matched layouts). Standard brick pavers are 8" × 4" × 2¼", but pavers come in countless sizes from 4" × 4" small accents to 24" × 36" "concrete pavers" for modern patios. The fundamental math: paver coverage = paver length × paver width / 144 sq ft, then divide area by coverage to get pavers needed.
The biggest cost factors beyond pavers themselves: base preparation (4-6" compacted crushed stone), bedding sand, polymeric sand for joints, and edge restraints. Materials beyond the pavers add 30-40% to project cost.

Formula
How to use this calculator
- Enter area length and width in feet.
- Enter paver dimensions in inches (length × width).
- Set waste factor (10% standard; 15% for diagonal/herringbone).
- Enter price per paver for cost estimate.
- Calculator returns paver count and material cost.
- Round up to full paver counts; buy from one batch to avoid color variation.
Worked examples
Backyard paver patio
**Scenario:** 15 × 12 ft backyard patio with standard 8 × 4 inch concrete pavers, running bond pattern. **Calculation:** Area: 180 sq ft. Pavers per sq ft (8×4): 4.5. Base: 810. With 10% waste: 891 pavers at $0.75 = $668 in pavers. Plus base materials (crushed stone, sand, polymeric sand, edging): ~$400. Total materials ~$1070. **Result:** Materials ~$1070 for 180 sq ft patio. Pro install would add $1500-2500. DIY save labor; budget 2-3 weekends for first-time install. Patio adds significant property value for the investment.
Front entry walkway
**Scenario:** 30 ft long × 4 ft wide front walkway with 6 × 6 inch concrete pavers. **Calculation:** Area: 120 sq ft. Pavers per sq ft (6×6 with 0.25 sq ft each): 4. Base: 480. With 10% waste: 528 pavers at $2 (premium 6×6) = $1056 in pavers. Plus base materials: ~$250. Total materials ~$1300. **Result:** ~$1300 in materials for upgraded paver walkway. Replaces older concrete walkway. Pro install $1200-1800. Adds curb appeal and matches popular landscape designs.
Large concrete paver pool deck
**Scenario:** 600 sq ft pool deck with 16 × 24 inch large-format concrete pavers, decorative border. **Calculation:** Field pavers (16×24 = 2.67 sq ft each): need 600/2.67 = 225 pavers. With 15% waste (large pavers, decorative border): 259 pavers. At $4/sq ft for large format: $2400 in pavers. Border 4×8 standard pavers, 40 lf perimeter, ~140 pavers at $1 = $140. Plus extensive base ($1000), polymeric sand ($150), edge restraint ($200), drainage: $3900 materials. Pro install $4000-7000. **Result:** ~$8000-12000 total for premium pool deck. Pool decks require special pavers (slip-resistant), proper drainage, and often heat-reflective materials. Quality installation is essential to prevent settling, water issues, and slip hazards.
When to use this calculator
**Use paver calculations for:**
- **Backyard patios**: most common application. - **Walkways and pathways**: foundation paths, garden paths. - **Driveways**: replacing or augmenting asphalt/concrete. - **Pool decks**: stylized surrounds. - **Outdoor kitchen areas**: defined seating/cooking spaces. - **Landscaping borders and edging**: framing planting beds. - **Steps and stairs**: outdoor stair construction.
**Why pavers vs concrete or asphalt:**
- **Pavers**: best aesthetics, easy repair, design flexibility. Higher initial cost. - **Concrete**: more affordable, durable, but cracks and is hard to repair. - **Asphalt**: cheapest, fast, but requires maintenance and looks utilitarian.
**Paver selection:**
- **Color**: factory-mixed pigment; expect slight variation. Choose for permanent look. - **Texture**: smooth (modern), tumbled (rustic), embossed (decorative). - **Size mix**: pavers in multiple sizes create dimensional interest. - **Permeability**: traditional pavers shed water; permeable pavers allow drainage. - **Slip rating**: important for pool decks and high-traffic walkways.
**Installation steps:**
1. **Excavate base**: 6-8 inches deep for patio. 2. **Install landscape fabric**: prevents weeds growing up through. 3. **Compact 4-6 inches of crushed stone in 2" lifts**: with plate compactor. 4. **Add 1" of bedding sand**: screed level. 5. **Lay pavers**: from one corner, work outward. 6. **Cut pavers with wet saw**: for borders and odd shapes. 7. **Install edge restraint**: aluminum or plastic with 10" spikes. 8. **Sweep polymeric sand into joints**: activated with light water mist. 9. **Compact**: lightly tap pavers with rubber mallet or plate compactor with cushion. 10. **Apply sealer (optional)**: protects against staining.
**Common installation mistakes:**
- **Inadequate base**: leads to settling, unevenness, and frost heave. - **No edge restraint**: pavers shift and move outward over time. - **Skipping landscape fabric**: weeds eventually penetrate. - **Wrong sand**: must be coarse "concrete sand" for bedding; polymeric for joints. - **Improper drainage**: water pooling damages base and pavers. - **Misaligned pattern**: visual mistakes compound across the project.
**Maintenance:**
- **Sweeping**: regular debris removal. - **Polymeric sand refresh**: every 5-7 years to fill joints. - **Power washing**: every 2-3 years. - **Seal coat**: optional, every 3-5 years. - **Weed control**: spot treatment for stubborn weeds in joints. - **Damaged paver replacement**: individual pavers can be lifted and replaced.
**Permeable pavers for drainage:**
- Allow water to infiltrate through joints. - Reduce runoff to storm drains. - Required in some jurisdictions for new construction. - Cost premium ~25-50% over standard pavers. - Require periodic vacuuming to keep joints clear.
**Pool deck specific considerations:**
- Slip-resistant surface. - Heat-resistant (lighter colors absorb less heat). - Salt-tolerant for saltwater pools. - Smooth top surface (no rough texture). - Drainage away from pool. - Coping pieces (rounded edge) at pool perimeter.
Common mistakes to avoid
- Skimping on base. 4-6" of compacted crushed stone is essential — inadequate base = settling.
- No edge restraint. Pavers shift outward and pattern fails.
- Wrong bedding material. Must be coarse concrete sand, not play sand.
- No polymeric sand in joints. Regular sand washes out and weeds grow.
- Improper compaction. Loose base or pavers will settle and crack.
- Forgetting drainage. Water pools damages pavers and undermines base.
- Mixing different paver lots. Color variation across project is permanent and visible.
