Planning a patio, walkway, or driveway project? Our paver calculator helps you determine exactly how many pavers you need, accounting for area dimensions, paver size, joint spacing, laying pattern, and waste factor. Get accurate material estimates including sand and gravel base requirements.
Paver calculation involves dividing your project area by the effective area of each paver (including joint spacing), then adding a waste factor for cuts and breakage. Different laying patterns require different waste allowances - simple stacked patterns need minimal extra material, while diagonal herringbone patterns require significantly more cuts at edges.
Paver Calculation Formula
Pavers = (Area ÷ Paver Area) × (1 + Waste%)Automatically adjusts waste percentage based on your chosen laying pattern - from 3% for simple stacked to 15% for diagonal herringbone.

It depends on paver size. For standard 4×8 inch pavers, you need about 4.5 pavers per square foot. For 6×6 inch pavers, about 4 per square foot. For 12×12 inch pavers, exactly 1 per square foot. Our calculator handles all sizes automatically.
Plan for 10-15% extra as a baseline. Add more for complex patterns: running bond needs 5% extra, herringbone 90° needs 10% extra, and herringbone 45° needs 15% extra due to edge cuts. Our calculator adds pattern waste automatically.
Herringbone patterns (90° or 45°) are strongest for driveways because the interlocking pattern resists shifting under vehicle weight. Running bond is also acceptable for light traffic. Stacked bond is not recommended for driveways.
For polymeric sand with 1/8 inch joints, one 50-lb bag covers approximately 50-75 square feet. Wider joints or deeper pavers require more sand. Our calculator estimates bags needed based on your project area and joint width.
For patios and walkways, a 4-inch compacted gravel base is standard. Driveways require 6-8 inches for vehicle support. Our calculator estimates gravel at 4-inch depth; adjust quantities for deeper bases.
12×12 inch pavers cover area quickly and have fewer joints to maintain. 6×6 or 6×9 inch pavers offer more design flexibility. 4×8 inch brick-style pavers create classic patterns but require more pieces and labor.
Yes! Many designs combine sizes for visual interest. Calculate each size separately based on your design layout, then sum the totals. Add extra waste for mixed patterns since fitting pieces together requires more cuts.
Break the area into rectangles, calculate each section separately, and add the results. For curves, calculate as if rectangular and add 15-20% extra waste for the edge cuts needed to create the curved shape.
