Paver Calculator: How Many Pavers for a Patio Without Overbuying

Ordering pavers is one of the most common overbuying mistakes in hardscaping. Order too few and you can't finish. Order too many and you're storing pallets of stone in your garage. Here's how to get it exactly right.

The Two-Step Formula

Step 1: Calculate Paver Area

  1. Measure your patio area in square feet: Length × Width
  2. Calculate one paver's area in square feet:
    • 4×8 inch paver = 0.222 sq ft
    • 6×6 inch paver = 0.25 sq ft
    • 6×9 inch paver = 0.375 sq ft
    • 12×12 inch paver = 1 sq ft
  3. Divide: Patio Area ÷ Paver Area = Base Count

Step 2: Add Waste Factor

The waste factor depends on your pattern and edge complexity:

Pattern / Edge TypeWaste Factor
Straight stack bond, square edges5–10%
Running bond, simple rectangle10%
Diagonal or herringbone15%
Curved edges or circles15–20%
Inlays or multi-pattern20%+

Real Examples

Example 1: 12×12 Patio, 4×8 Inch Pavers, Running Bond

Patio area: 12 × 12 = 144 sq ft
Paver area: 4 × 8 = 32 sq in = 0.222 sq ft
Base count: 144 ÷ 0.222 = 649 pavers
With 10% waste: order 714 pavers (round to 720)

Example 2: 20×20 Patio, 6×6 Inch Pavers, Herringbone

Patio area: 20 × 20 = 400 sq ft
Paver area: 6 × 6 = 36 sq in = 0.25 sq ft
Base count: 400 ÷ 0.25 = 1,600 pavers
With 15% waste (herringbone): order 1,840 pavers

Example 3: 8×40 Walkway, 6×9 Inch Pavers, Running Bond

Area: 8 × 40 = 320 sq ft
Paver area: 6 × 9 = 54 sq in = 0.375 sq ft
Base count: 320 ÷ 0.375 = 853 pavers
With 10% waste: order 939 pavers (round to 940)

Don't Forget Base Materials

Pavers sit on a base of compacted gravel and sand. For most residential patios:

⚠️ Common Paver Mistakes

  • Skipping the gravel base: Pavers on dirt shift, sink, and grow weeds. The base is non-negotiable.
  • Ordering exact count:You'll need extras for cuts, breakage, and future repairs. 10% minimum, 15% for diagonal patterns.
  • Ignoring paver thickness:Driveways need 2¾" thick pavers. Patios and walkways can use standard 2⅜" pavers.

When to Use Our Calculator

Our free paver calculator handles all of this — including paver size selection, pattern waste adjustments, and base material estimates. It even calculates the edging linear footage you need.
