Paver Calculator
Count the pavers for a patio or walkway from the project size and paver dimensions. Get the field paver count with waste, an optional border course, and the pavers-per-square-foot for your exact paver and joint.
Paver face size and the sand joint between them (butted ≈ 0).
Advanced: border course & price
Perimeter auto-fills from length × width. Leave border length blank to skip the border.
Formula & how it works
Each paver covers (length + joint) × (width + joint) in². Pavers per ft² = 144 ÷ that.
Field pavers = area × pavers per ft² × (1 + waste), rounded up. Border pieces = perimeter × 12 ÷ border length × (1 + waste), rounded up.
Worked example
A 16 × 12 ft patio is 192 ft². With 6 × 6 in pavers and a ⅛ in joint, each covers about 37.5 in², so 144 ÷ 37.5 ≈ 3.84 pavers per ft². At 10% waste that's 811 field pavers. A 6 in border around the 56 ft perimeter adds about 124 pieces.
Estimating a paver project
The joint counts
The sand joint between pavers is small but it adds up across hundreds of units — a wider joint means each paver covers more ground and you need fewer. Enter your actual paver face size and planned joint, since "6-inch" pavers are often slightly under and the joint varies by paver style. The pavers-per-square-foot figure updates so you can sanity-check against the supplier's coverage.
Pattern drives the waste
A running-bond or stack layout cuts cleanly and wastes little, while herringbone, diagonal, and any curved edge leave lots of angled offcuts. Bump the waste up for those, and always order a bit extra from the same production batch — pavers vary in shade between batches, and matching later for a repair is nearly impossible.
Don't forget what's under and around
Pavers are only the surface. A lasting patio needs a compacted gravel base, a bedding sand layer, edge restraint to keep the field from spreading, and joint sand swept in on top. Those are separate materials to plan and budget — the border course this tool counts is what locks the visible edge in place.
