Paver Calculator
Calculate how many patio pavers you need from project area and individual paver size, with waste built in.

Joint width can slightly change piece count for interlocking systems. When in doubt, round up a full bundle.
How this calculator works
Divide the patio area by the face area of one paver, then add waste for cuts and breakage.
Don’t forget base gravel and bedding sand - use the gravel and sand calculators for the layers underneath.
pavers = ceiling((patio area ÷ paver area) × waste)
- Measure paver face size, not including joints if using spacers
- 10% waste for rectangular patterns
- Order edge restraints and polymeric sand separately
Frequently asked questions
How many pavers do I need for a patio?
Convert paver size to square feet and divide into the patio area. A 12×12 patio (144 sq ft) with 6×9 pavers (~0.375 sq ft each) needs about 384 pavers before waste.
How much waste for pavers?
10% is typical for straight patterns. Circles, diagonals, and borders need more - often 15%.
What base do pavers need?
Many patios use compacted gravel base plus about 1 inch of bedding sand. Run those volumes in the gravel and sand calculators.
