Paver Calculator — How Many Pavers Do You Need?

Calculate exact paver quantities with layout pattern waste factors, plus crushed gravel sub-base, bedding sand, and polymeric joint sand.

Building an interlocking paver patio, walkway, or driveway? Paver projects require more than just calculating block surface area — you must budget for angle-cut waste, a compacted crushed stone foundation, sharp bedding sand, and joint-lock polymeric sand. Use our comprehensive hardscape planner to price and stage your entire installation.

Purchasing Recommendation

Order 881 × Standard Holland (6" x 9") Units

Pallets typically hold 300 to 450 standard 6x9 pavers (approx. 90-110 sq.ft per pallet). You will also need 4.07 cu.yds crushed gravel base and 0.93 cu.yds washed concrete sand.

Never use standard fine play sand for bedding pavers; only use coarse washed concrete sand (ASTM C-33) to allow free water percolation.

Paver Unit & Foundation Layer Formulas

Unit count combines single-block square footage with pattern-specific cutting allowances, alongside 4-inch base gravel and 1-inch bedding sand layers:

Pavers = ⌈(Patio Area ÷ Paver Area) × (1 + Pattern Waste%)⌉ | 4-inch Base Gravel (Cu Yds) = (Area × 0.333ft × 1.10) ÷ 27

Step-by-Step Step Rule:

  1. 1Input your patio length and width (or direct square footage).
  2. 2Select standard paver dimensions (brick 4x8, Holland 6x9, square 12x12, 16x16, 24x24).
  3. 3Choose your laying pattern (Running bond, Herringbone, Basketweave) to apply precise angle-cut allowances.
  4. 4Review the base materials checklist: crushed stone subgrade, sharp concrete sand bed, and polymeric joint sand.

Frequently Asked Questions (FAQ)

Standard straight patterns (such as Running Bond or Stack Bond) require 5% to 8% extra pavers for edge cuts. Diagonal layouts and 45° or 90° Herringbone patterns require 10% to 15% extra material due to frequent angle cuts along curved perimeter borders and edge restraints.
