Formulas Used

Pavers Needed

pavers_needed = ceil(area_sqft / paver_sqft * (1 + waste_percent / 100))

Total Area

area_out = area_sqft

Pavers per Sq Ft

pavers_per_sqft = 1 / paver_sqft

How It Works

Paver Calculation

Pavers per Sq Ft = 144 / (Paver Length × Paver Width)

Total Pavers = Area × Pavers per Sq Ft × (1 + Waste%)

Add 10% waste for straight layouts, 15% for diagonal or circular patterns.

Worked Example

12×10 ft patio with 8×4 in pavers and 10% waste.

area_length = 12area_width = 10paver_length = 8paver_width = 4waste_percent = 10
  1. 01Area = 120 sq ft
  2. 02Paver area = 8×4/144 = 0.222 sq ft
  3. 03Pavers per sq ft = 4.5
  4. 04Base pavers = 120 × 4.5 = 540
  5. 05With 10% waste = 594 pavers
