Paver Calculator — Pavers, Sand & Base Material

    Calculate how many pavers you need for patios, walkways, and driveways. Includes paver sand, gravel base, and polymeric sand estimates.

    10% waste recommended

    Tips

    • • Always compact the gravel base in 2-inch lifts — don't dump 4 inches and compact once
    • • Leveling sand should be screeded flat, never compacted before laying pavers
    • • Run a plate compactor over finished pavers to set them into the sand bed
    • • Sweep polymeric sand into joints and mist with water to activate — don't flood it

    Estimates only — paver sizes vary by manufacturer. Base material depth depends on soil conditions and intended use.

    Example Calculation

    Building a 12×16 foot patio with 6×9 inch pavers in a running bond pattern at 10% waste? The area is 192 square feet, requiring approximately 564 pavers. For the base, you need about 2.4 cubic yards of gravel (3.2 tons), 0.6 cubic yards of leveling sand, and 8 bags of polymeric sand. At $0.50–$1.50 per paver, the pavers alone cost $282–$846.

    Frequently Asked Questions

    How many pavers do I need per square foot?

    It depends on the paver size. Standard 4×8 inch brick pavers: 4.5 per sqft. 6×9 inch: 2.67 per sqft. 12×12 inch: 1 per sqft. Always add 10% waste for straight layouts, 15% for herringbone or diagonal.

    How deep should the gravel base be for pavers?

    4 inches of compacted gravel for patios and walkways. 6–8 inches for driveways. Top with 1 inch of leveling sand before setting pavers. In areas with poor drainage or freeze-thaw cycles, go deeper.

    What's the best pattern for a patio?

    Running bond is the easiest to lay and wastes the least material. Herringbone is the strongest for driveways because it locks pavers together under load. Basketweave gives a classic look with moderate difficulty.

    How much sand do I need under pavers?

    1 inch of leveling sand over the compacted gravel base. For a 200 sqft patio, that's about 0.6 cubic yards of sand. Don't use more than 1.5 inches — too much sand causes pavers to shift and settle unevenly.

    Do I need edge restraints?

    Yes. Without edge restraints, pavers along the perimeter will gradually shift outward. Use plastic or aluminum paver edging staked into the gravel base along the entire perimeter.

    Typical Results

    Walkway(3' × 20')65–70 sq ft of pavers
    Patio(12' × 16')205–220 sq ft of pavers
    Driveway(10' × 40')440–465 sq ft of pavers

    💡 Order base gravel in tons: a 4" base at 1.4 tons per yd³ means roughly 0.6 tons per 100 sq ft.

    Common Mistakes

    • Forgetting that a diagonal lay pattern wastes 15% more pavers than straight lay
    • Not including edging restraint material to keep borders from shifting
    • Calculating base material for the paver area but not the overexcavation needed for borders
