Pavers Calculator
Estimate how many pavers a patio or path needs. This assumes a common 6x9 inch paver (about 4.5 per square foot); adjust if yours differ.
Pavers calculator
How it's calculated: Length ft × width ft = square feet; add 5% waste, multiply by about 4.5 pavers per square foot, and round up.
How to estimate pavers
- Buy 5-10% extra for cuts around edges and curves, and keep a few spares for future repairs.
- Paver count per square foot depends on size: larger format pavers mean fewer pieces.
- Order all pavers in one batch so the color lot matches.
- Install edge restraint around the perimeter - without it the field spreads and joint lines open up over time.
- Plan the layout so cut pavers land along the least visible edge.
Frequently asked questions
How many pavers per square foot?
It depends on size. A 6x9 inch paver is about 4.5 per sq ft; a 12x12 is 1 per sq ft; a 4x8 brick paver is about 4.5 per sq ft.
Roughly how many pavers will a patio take?
As an example, a 144 sq ft patio needs about 680 of the common 6x9 inch size after 5% waste, or roughly 155 twelve-inch squares. Larger formats mean fewer pieces to set.
What goes between pavers?
Sweep joint sand into the gaps after compacting. Polymeric sand costs more but hardens when wetted, which slows weeds and keeps ants from mining the joints.
Do pavers need mortar?
Most patios and walkways are dry-laid: compacted gravel base, 1 inch of bedding sand, pavers, then joint sand. Mortar only comes in when you are setting pavers over an existing concrete slab.
Are pavers cheaper than a concrete slab?
Usually not on material - pavers plus base and sand cost more than plain concrete. The tradeoff is repairability: you can lift and relay individual pavers, while a cracked slab means patching or replacement.
