Paver Calculator

Determine the total area of your patio by multiplying width by length. Then calculate the area of a single paver (width x length). Divide the patio area by the paver area, and round up to the nearest whole number. For example, a 10 ft x 12 ft patio (120 sq ft) with 6x6 inch pavers (0.25 sq ft each) needs 120 / 0.25 = 480 pavers.

You need 81 pavers. Calculate your patio area: 12 ft x 12 ft = 144 sq ft. Then calculate one paver's area: 16 in x 16 in = 256 sq in = 1.78 sq ft. Divide the total area by the paver area: 144 / 1.78 = 81 pavers.

You need exactly 100 pavers. Each 12x12 inch paver covers 1 square foot (12 in x 12 in = 144 sq in = 1 sq ft). So for 100 sq ft, simply divide: 100 / 1 = 100 pavers. Add 10% for waste, bringing the total to 110 pavers.

It depends on the paver size. Standard 4x8 inch brick pavers need about 4.5 per square foot. Standard 6x6 inch pavers require 4 per square foot. Larger 12x12 inch pavers need just 1 per square foot. Use the calculator above to get an exact count for your paver dimensions.

No. Although the area and paver size may be identical, 45-degree patterns (like herringbone at 45 degrees) require more pavers than 90-degree patterns. This is because diagonal layouts need extra cuts along the edges to fill the remaining triangular spaces, typically adding 10-15% more material waste.

A 10% waste factor is standard for most rectangular patterns like running bond and stacked bond. Increase to 15% for 90-degree herringbone or curved edges. For 45-degree herringbone or complex designs with many cuts, plan for up to 20% extra material.

Material costs typically range from $3-$6 per square foot for basic concrete pavers and $8-$15 for premium natural stone. Professional installation adds $8-$20 per square foot depending on your location. A 200 sq ft patio averages $2,000-$5,000 fully installed.

Herringbone (90 degrees or 45 degrees) is the strongest pattern for driveways because the interlocking zigzag design distributes vehicle weight evenly and resists shifting under traffic. Running bond is also suitable for lighter vehicle areas like residential driveways.

Yes, a proper base is essential. You need 4-6 inches of compacted crushed gravel, topped with 1 inch of leveling sand. Without a solid base, pavers will settle unevenly, crack, and develop drainage problems. The base is arguably the most important part of any paver installation.

Standard patio pavers are 2 inches (5 cm) thick, which is sufficient for pedestrian traffic. For driveways and areas with vehicle traffic, use pavers at least 3 inches (7.6 cm) thick. The 14x14 inch format typically comes in 3-inch thickness, while 12x18 inch pavers are usually 1.5 inches thick.

Yes, you can overlay pavers on sound, level concrete that drains well. Apply a thin layer of bedding sand over the concrete, then lay your pavers. Make sure the final surface height works with doorways, steps, and adjacent areas so you do not create tripping hazards.

Well-installed paver patios last 25-50 years or more. The key factors are a properly compacted gravel base, good drainage slope, and occasional maintenance like re-sanding joints every 2-3 years. Unlike poured concrete that can crack, individual pavers can be replaced if damaged.

For a 200 sq ft patio you need roughly 133 bags (0.5 cu ft each). Here is the formula: multiply your area by the base depth in feet, then divide by the bag size. A standard paver base is 4 inches deep for patios and 6 inches for driveways. Example: 200 sq ft × 0.33 ft (4 in) = 66 cu ft ÷ 0.5 cu ft per bag = 132 bags. Round up to 133 and buy a few extra to account for compaction loss, which typically reduces volume by 10-15%.

For a 200 sq ft patio you need about 34 bags of bedding sand (0.5 cu ft each). Use this formula: area × depth in feet ÷ bag size. Bedding sand is laid 1 inch deep over the compacted base. Example: 200 sq ft × 0.083 ft (1 in) = 16.6 cu ft ÷ 0.5 = 33.2 bags, rounded up to 34. You will also need polymeric sand for the joints after the pavers are laid — plan for roughly 1 bag per 25-30 sq ft depending on joint width.
