About this calculator

Patio area for material orders. Pavers: count by ft² per piece. Concrete: 4 inches thick × area / 27 = cubic yards. Add 5-10% waste for paver cuts at edges; 10% for concrete.

Frequently asked

4 inches thick for concrete?+
Standard for residential patios with no vehicle traffic. Driveways need 4-6 inches.
Paver pattern matters?+
For waste calculation: yes. Diagonal patterns waste 15-20%; running bond ~10%.
Sand bedding?+
1 inch of sand under pavers — adds another cubic-yard calc. See sand-volume.
Edge restraints?+
Linear feet of edging needed = perimeter. Required for paver patios to prevent shifting.
Drainage slope?+
2% (about ¼ in/ft) away from house. Critical to prevent water pooling.
