How to Use This Calculator
- Enter the patio length and width in feet.
- Select your paver size from the common presets.
- Choose the joint width between pavers (3/16" is standard).
- Set a waste factor — 10% for most layouts, 15% if you have curves or diagonal cuts.
- Click "Calculate Paver Materials" for a complete material list including base materials.
The Formula
Pavers = Patio Area ÷ ((Paver Width + Joint) × (Paver Length + Joint) ÷ 144)
Each paver's effective area includes one joint width on each dimension. The result is in square inches, divided by 144 to convert to square feet.
Leveling Sand (tons) = (Area × 1″ depth ÷ 12) × 100 lbs/cu ft ÷ 2000
Gravel Sub-Base (tons) = (Area × 4″ depth ÷ 12) × 105 lbs/cu ft ÷ 2000
Edge restraint equals the perimeter of the patio in linear feet.
