Paver Calculator
Paver count for patios, walkways, and driveways
What is paver calculator?
Paver count is area ÷ paver sqft × (1 + waste factor), ceiling to a whole number. A 6×9 in paver covers 0.375 sqft; an 8×8 covers 0.444 sqft; a 12×12 covers exactly 1 sqft. Enter the nominal paver dimensions in inches and the widget handles the unit conversion — no need to do the inches-to-feet math yourself. The 10% default waste covers all perimeter cuts plus a handful of breakages from the wet saw.
Pattern selection drives the cut rate. Running bond (half-offset rows) is the industry default for residential patios — it’s structurally stronger than a grid and still produces only ~10% waste. Herringbone (45° or 90°) is popular for driveways because it locks under vehicular load, but diagonal herringbone adds 15-20% waste since every perimeter paver gets an angled cut. Basketweave is forgiving on cut count but needs uniform paver dimensions to line up — stick to 10% waste. If your layout has curves, add 5% on top of whatever pattern waste you’d otherwise use.
Paver size by use case: small pavers (6×9, 8×8) work better on curved paths where the small unit radius keeps joint lines from fanning visibly. Large pavers (12×24, 18×18) cover ground faster on open patios but are heavy to set by hand and waste more per cut on narrow projects. For a walkway under 4 ft wide, pavers larger than 12×12 create awkward proportions and more offcuts than they save in labor.
Base and restraint are not optional. A sand-set paver system requires 4-6 in of compacted aggregate base, 1 in of screeded bedding sand, and plastic or aluminum edge restraint on every exposed edge. Skip the restraint and the field will migrate outward within two freeze-thaw cycles. For driveways, bump the base to 6-8 in and use 60 mm (2.36 in) thick pavers rated for vehicular load — standard residential pavers at 40 mm will crack under a car tire within a few years.
When to use a paver calculator
- Backyard patio — A 12 × 16 ft patio with 6×9 in pavers covers 192 sqft. At 10% waste that's 564 pavers — enough for a standard running-bond layout with full cuts on every perimeter edge. Order in whole pallet quantities; most suppliers ship 80-100 pavers per pallet.
- Front walkway — A 3 × 20 ft walkway with 12×12 in pavers is 60 sqft, yielding 66 pavers at 10% waste. The narrow width means almost every edge row needs a lengthwise cut, so the 10% covers it — a wider walkway with more full pavers could shave that to 7%.
- Driveway extension or apron — A 200 sqft driveway apron in 8×8 in pavers requires 495 pavers at 10% waste. For driveways, use concrete pavers rated for vehicular load (60 mm or thicker) and increase your base thickness to 6-8 in of compacted aggregate.
How to use the Paver Calculator
- Measure the project area — Length × width in feet. For curves or odd shapes, break into rectangles or use Total area with a hand-measured estimate.
- Enter paver dimensions — Length × width in inches. Common: 6×9, 8×8, 12×12, 12×24. Account for the joint width — tightly butted pavers cover ~3% more area than wide-jointed.
- Pick a waste factor — 10% is standard. Add 5% more for curved layouts that need diagonal cuts.
Worked examples
Patio 12 × 16 ft, 6×9 pavers
Input: L 12, W 16, paver 6×9 in
Output: 564 pavers (192 sqft + 10% waste)Walkway 3 × 20 ft, 12×12 pavers
Input: L 3, W 20, paver 12×12 in
Output: 66 pavers (60 sqft + 10% waste)Driveway apron: 200 sqft, 8×8 pavers
Input: Total area 200 sqft, paver 8×8 in
Output: 495 pavers (200 sqft + 10% waste)
