Paver calculators size the three layers of an interlocking paver patio, walkway or driveway: the pavers on top, the bed of sand under them and the compacted gravel base that carries the load. Each layer is bought differently, pavers by the piece or the pallet, sand by the ton or the bag and base gravel by the ton, so each one has its own tool, and each tool lists the material sizes sold at supply yards and home centers. Used together, they turn a measured area into a complete material order with a cost range for each part.
Paver tools
| Calculator | Layer | Main result |
|---|---|---|
| Paver Calculator | Pavers | Pavers per square foot, count with pattern waste, material cost |
| Paver Sand Calculator | Bedding sand and joint sand | Tons and bags of bedding sand, bags of polymeric sand |
| Paver Base Calculator | Compacted gravel base | Compacted and loose cubic yards, tons to order |
How the layers fit together
A paver surface is a flexible pavement. The pavers spread load into the sand bed, the sand bed sits on a dense gravel base, and the base spreads that load over compacted soil. The site’s default base depth is 4 inches under a patio, with a 1.2 compaction factor on the loose order, and the bedding layer defaults to 1 inch of screeded sand. Driveways need a deeper base, and the paver base calculator lists the ICPI depth ranges for walks and driveways.
Paver counts depend on face size and pattern, and small holland stones need 4.50 pieces per square foot. Running bond carries a 5 percent cut allowance, while 45 degree herringbone carries 15 percent, since every edge needs angled cuts.
Using the three calculators in order
- The finished outline gets measured, plus the strip of base that runs past the edge restraint on open sides.
- The paver calculator gives the paver count with pattern waste.
- The base calculator gives the gravel order in tons for the chosen depth.
- The sand calculator gives the bedding sand and the polymeric joint sand.
- Edge restraint, geotextile and tool rental round out the list.
The same area goes into all three tools, so the numbers line up, and each tool keeps its own exclusions list so nothing gets counted twice.
Pavers or poured concrete
A paver patio and a concrete slab cover the same ground in very different ways. Pavers flex with the soil, can be lifted and relaid after a repair and leave no control joints to crack, while concrete goes down faster and usually costs less per square foot. The concrete slab calculator and the concrete cost calculator price the poured version of the same footprint for a side by side comparison.
Upkeep after installation
Joint sand settles after the first heavy rains and needs topping up, and polymeric sand that cracks or washes out gets swept and reactivated. Sealing protects color and can stabilize joints. The paver sealing cost guide covers sealer types and what installers charge. For the full job, the paver installation cost guide prices a crew built patio layer by layer, and the pavers vs concrete guide weighs pavers against a poured slab.
When a hardscape contractor helps
Patios and walkways are common weekend projects, but driveways, wet sites, slopes and soft clay soils change the base design and benefit from a contractor’s experience. A plate compactor, a wet saw for cuts and an 811 call before digging are part of every job, and silica dust from cutting concrete pavers calls for wet cutting or a respirator.
