How Many Pavers Do I Need? Patio and Driveway Guide
The formula
Area ÷ one-paver area = count, then add cutting waste. Measure length × width in feet. One 12×12 inch paver covers exactly 1 sq ft; 6×6 covers 0.25 (4 per sq ft); 4×8 brick covers 0.22 (4.5 per sq ft). Straight patterns add 10% waste, diagonal 15%. Test numbers in our Paver Estimator.
The waste percentage is not padding, it is a cutting allowance. Every time a paver meets an edge, a step, or a wall, somebody has to cut it, and half of each cut paver is offcut. Curves and herringbone patterns waste more because almost every perimeter piece is a one-off.
Pavers per square foot
| Paver size | Coverage each | Pavers per sq ft | Per 100 sq ft, 10% waste |
| 12×12 in | 1 sq ft | 1 | 110 |
| 6×6 in | 0.25 sq ft | 4 | 440 |
| 12×24 in | 2 sq ft | 0.5 | 55 |
| 4×8 in brick | 0.22 sq ft | 4.5 | 495 |
Buy by pallet where you can. Pallets hold a fixed piece count and suppliers price them better than loose units, plus the pieces in one pallet share a dye lot — two pallets from different production runs can differ enough to show as a seam across the middle of a patio.
Worked example: 12×10 ft patio
Area = 120 sq ft. With 12×12 pavers: 120 + 10% = 132 pavers. With 6×6 pavers: 480 + 10% = 528. With 4×8 brick in herringbone: 540 + 15% = 621. Round up to full pallets — suppliers discount whole pallets and you want matching dye lots.
Keep a dozen spare pavers stacked behind the shed. One cracked piece from a dropped log or a settling step is a five-minute swap while the colour still matches the pallet you laid — and an impossible match once the dye lot is gone.
Base matters more than pavers
- Patios: excavate 4–6 inch, compacted gravel, 1 inch bedding sand
- Driveways: 8–12 inch base with 60 mm+ thick pavers
- Slope 1 inch per 8 ft away from the house for drainage
- Polymeric sand swept into joints blocks weeds and ants
- Edge restraints stop spreading — never skip them
Rent a plate compactor for the base rather than tamping by hand. Gravel compacted in 2-inch lifts with a machine does not settle afterwards, while a hand-tamped base keeps moving for a season and takes the pavers out of level with it.
Paver types compared
Concrete pavers are cheapest and uniform; clay brick holds color forever but costs more; natural stone is premium and irregular, so add extra waste. For driveways, never use thin 30 mm patio pavers — they crack under cars.
Thickness, not surface style, is what you are paying for. A 60 mm paver and a 30 mm paver can look identical in the showroom and behave completely differently under a wheel — check the number on the label before the pattern catches your eye.
Limits and assumptions
Estimates ignore transit breakage and complex curves — add 5% more for circles and S-curves. Labor often exceeds materials on driveways, so collect 3 itemized quotes. More detail in our home improvement guides.
Planning checklist before you buy
Call 811 for utility marking, confirm HOA rules on color and pattern, and check drainage — pavers over a low spot become a pond. Order 2–3 sample pavers to test color in your light; showroom lighting lies. Photograph the pallet tags so replacements match the dye lot.
DIY vs pro
A small straight patio is a fair weekend DIY: excavate, compact in 2-inch lifts, screed sand, lay, compact with a mat, sweep polymeric sand. Hire out driveways, herringbone curves, and anything needing a retaining wall — base mistakes telegraph through within a year.
FAQ
- Weeds between pavers? Polymeric sand plus annual top-up beats landscape fabric alone.
- Seal or not? Sealers deepen color and resist stains but need re-coating every 2–3 years.
- Can I lay over concrete? Yes with thin overlay pavers and drainage gaps — never mortar standard pavers flat.
- How long does it take? A 120 sq ft straight patio is one weekend for the base and one for laying and sanding, assuming dry weather.
- Does pattern change the count? Only the waste factor: straight runs take 10%, diagonal and herringbone take 15% or more.
Maintenance after install
Sweep polymeric sand into joints after the first rain, top up annually, and pull weeds before they seed. Pressure-wash on low fan setting — a zero-degree tip etches concrete pavers permanently. Re-seal every 2–3 years if you sealed originally, and keep spare pavers from the same dye lot for repairs.
