How many pavers do I need?
Pavers = area ÷ paver size × (1 + waste)
A patio 12 ft by 12 ft with 6 × 9 in pavers: 144 ft² ÷ 0.375 ft² = 384 pavers. Add 5% for a running bond and order about 404.
The gaps between pavers mean each one covers slightly more ground, so the calculator includes the joint width you enter. Keep a few spare pavers from the same batch for future repairs.

What goes under pavers
The calculator works out base gravel and bedding sand in cubic yards and tons, using about 1.35 tons per cubic yard (1.6 t/m³) for both.
