Paver Calculator
Estimate pavers needed for a patio, walkway or driveway in seconds.
This paver calculator converts your patio or walkway dimensions into an exact paver count. Enter your project length and width, the size of a single paver, and a waste percentage for cuts and breakage — we'll calculate the total project area, area per paver, and how many pavers to order so you can shop with confidence.

How to Use the Paver Calculator
- 1Measure the length and width of your patio or walkway area in feet.
- 2Measure a single paver's length and width in inches — check the manufacturer spec if unsure.
- 3Choose a waste percentage — 10% for simple layouts, 15%+ for patterns, curves or borders.
- 4Read your results instantly: total area, area per paver, pavers needed, and total pavers to buy.
- 5Take the "Total Pavers to Buy" number to your supplier, along with your base material needs.
Example Calculation
Say you're building a 16 ft x 12 ft patio using 12" x 12" pavers, with a 10% waste factor. Total project area = 16 × 12 = 192 sq ft. Area per paver = (12 ÷ 12) × (12 ÷ 12) = 1 sq ft. Estimated pavers needed = 192 ÷ 1 = 192. Extra pavers for waste = 192 × 0.10 = 19.2, rounded up to 20. Total pavers to buy = 192 + 20 = 212 pavers.
Common Paver Project Tips
- Order 10% extra pavers for simple layouts and 15%+ for patterns like herringbone, circles, or diagonal running bond.
- Buy all pavers from the same production lot or batch to avoid visible color and shade variation across the patio.
- Plan a compacted gravel base (4-6 inches) and a 1 inch bedding sand layer before laying pavers — skipping base prep leads to shifting and settling.
- Leave a slight slope (about 1/4 inch per foot) away from structures for proper drainage.
- Keep a few spare pavers after the project is finished for future repairs, since dye lots are often discontinued.
- Use edge restraints (plastic, metal or concrete) along the perimeter to keep pavers locked in place over time.
Accuracy & Assumptions
- Results are estimates only.
- Paver dimensions, coverage and packaging can vary by manufacturer and supplier.
- Consider ordering an additional 5–10% for cuts, breakage and pattern layout.
- Verify all project measurements before purchasing materials.
- Check local building codes and manufacturer recommendations for base depth where applicable.
Frequently Asked Questions
How many pavers do I need for a 10x10 patio?
For a 10 ft x 10 ft patio (100 sq ft) using 12" x 12" pavers (1 sq ft each), you need 100 pavers before waste. Adding a 10% waste factor brings the total to about 110 pavers.
How much waste should I add for a paver project?
Use 10% waste for a simple straight-edge layout, and 15% or more for circular patios, herringbone patterns, or designs with lots of borders and cuts.
Do I need a base layer under pavers?
Yes. A compacted gravel base (typically 4-6 inches) topped with 1 inch of bedding sand is standard for stable, long-lasting paver patios and walkways.
How do I calculate paver area if my pavers are not square?
Multiply the paver length by the paver width (in inches), divide by 144 to convert to square feet, then divide your total project area by that number to get the paver count.
Can this calculator handle irregular patio shapes?
Break an irregular shape into rectangles, calculate each section separately, then add the results together for your total paver count.
This calculator provides an estimate for planning purposes only. Material needs vary by paver pattern, cutting waste and supplier packaging — always confirm final quantities with your paver supplier before purchasing.
