How many pavers do I need per square foot?

It depends on paver size. Standard 4x8-inch pavers require about 4.5 pavers per square foot. Larger 6x9-inch pavers need roughly 2.7 per square foot. Always add 5-10% extra for cuts and waste.

How do I calculate pavers for a patio?

Multiply the patio length by width to get total square footage. Divide by the area of one paver in square feet to get the number needed, then add 10% for cuts, breakage, and future replacements.

How much sand do I need under pavers?

Apply a 1-inch layer of leveling sand over the compacted gravel base. One cubic yard of sand covers approximately 324 square feet at 1 inch deep. You will also need polymeric sand to fill the joints after laying.

What is the standard paver size?

The most common paver size is 4x8 inches (roughly the size of a standard brick). Other popular sizes include 6x6, 6x9, and 12x12 inches. Thickness is typically 2-3/8 inches for pedestrian areas.

How many pavers do I need per square foot?

Depends on paver size. 4×8 brick: 4.5 pavers/sq ft. 6×6: 4 pavers/sq ft. 6×9: 2.67 pavers/sq ft. 8×8: 2.25 pavers/sq ft. 12×12: 1 paver/sq ft. Add 5-10% waste for cuts on straight rectangle patios; 10-15% for herringbone patterns; 15-20% for circular patterns. Always round UP — running short mid-job from a different dye lot means visible color mismatch.

How deep should the gravel base be?

For patios/walkways: 4-6 inches compacted base. For driveways: 6-10 inches compacted base. For areas with clay soil or poor drainage: add 2 inches. Base depth is the #1 factor in long-term patio stability. Under-prepped base causes settling within 1-3 years — the most common warranty callback in hardscape work.

Do I need polymeric sand for paver joints?

Yes — polymeric sand prevents weed growth, ant infestation, and joint washout. Standard joint sand washes out within 6-12 months in most climates. Polymeric sand activates with water and forms a flexible bond that lasts 5-10 years. One 50 lb bag covers 30-75 sq ft depending on paver size and joint width — wider joints and smaller pavers use more sand.

How long does paver installation take?

Experienced 2-person crew installs about 50-75 sq ft per day for paver patios with proper base prep (excavation + base + sand + pavers + polymeric sand + compaction). A typical 300 sq ft patio is a 4-6 day project for one crew. Drive cycles to material supplier and weather can extend timeline. Plan for 3 day weeks instead of 5 day weeks to account for setbacks.

What's the difference between concrete pavers and clay pavers?

Concrete pavers are manufactured from cement and aggregate, available in many colors and textures, less expensive ($2-$6/sq ft material). Clay pavers (also called brick pavers) are kiln-fired clay, retain color permanently, more durable, and significantly more expensive ($5-$15/sq ft material). Clay pavers don't fade over time but cost 2-3x more. Concrete pavers offer better design flexibility; clay offers timeless durability and color stability.

Pro Tips

Order full pallets when possible. Paver pallet pricing is 10-20% better than individual sq ft pricing. A typical pallet is 90-110 sq ft of 4×8 brick, or 50-75 sq ft of larger formats.
Geotextile fabric is non-optional. Without fabric between subgrade and gravel base, the base sinks into soil over time. The $0.30/sq ft you save by skipping fabric becomes a callback that destroys job margin.
Compact in lifts.Don't dump 6 inches of gravel and compact once. Compact in 2" lifts with a plate compactor for proper density. Skimping here = settling later.
Edge restraint matters. Plastic or aluminum paver edging holds the patio together. Skipping edge restraint = pavers spread outward within 1-2 years, especially at high-traffic edges.
Polymeric sand application:Sweep into joints when pavers and joints are completely DRY. Then mist with water (don't flood). Activation needs water but not saturation. Done wrong, polymeric sand hazes the paver surface permanently.

How to Use This Calculator

Select your project area shape -- rectangle, circle, or irregular (enter total square footage directly). Choose your paver size, joint width, and laying pattern. The calculator automatically adjusts the waste factor for herringbone patterns. Set your gravel base depth (4-6 inches is standard) and the tool will estimate all materials including pavers, gravel base, sand setting bed, polymeric joint sand, edge restraint, and geotextile fabric.

Formula Used

Pavers per sq ft = 144 / ((paver_width + joint) x (paver_length + joint)). Gravel Base (CY) = Area x Depth (ft) / 27. Sand Setting Bed (CY) = Area x (1/12) / 27. Polymeric Sand coverage varies 30-75 sq ft per 50 lb bag based on paver size and joint width.
