Paver Calculator
Use this patio paver calculator to estimate pieces or packs from your project area and product coverage. Account for joint spacing and cuts, then add separate base and bedding sand volumes if you know the layer depths.

How Many Pavers Do I Need?
Start with the area you will pave, including its joints. A rectangle uses length × width. Add non-overlapping sections for an L-shaped patio, or enter a measured area directly. Divide that square footage by the installed coverage of one paver or complete pack.
Whole units = round up [area × (1 + extra allowance ÷ 100) ÷ coverage per unit]
For a 10 × 10 ft patio and a true 4 × 8 in laying module, coverage per paver is 32 ÷ 144 = 0.2222 ft² when displayed. Using the unrounded value gives 450 pavers. A chosen 5% allowance gives 472.5, rounded once to 473 pavers. The 5% is an example, not a setting recommended for every layout.
4x8 and 12x12 pavers per square foot
| Module | Pavers per ft² | Pavers for 100 ft² |
|---|---|---|
| 4 × 8 in | 4.5 | 450 |
| 6 × 6 in | 4 | 400 |
| 12 × 12 in | 1 | 100 |
| 16 × 16 in | 0.5625 | 57 |
Use the 4 × 8 or 12 × 12 example in the calculator only if it matches your product's laying module. A nominal size on the product name may differ from the actual face dimensions or installed coverage.
How do I calculate pavers for a circle?
Choose Circle and enter the diameter: area = π × (diameter ÷ 2)². A 10 ft diameter circle has about 78.5398 ft² of area. A circle paver calculator estimates the surface quantity; it does not determine ring-by-ring wedge pieces or which edge cuts can be reused. For a manufactured circle kit, use its coverage and layout instructions.
Joint Spacing, Patterns and Pallet Coverage
When using a paver calculator with spacing, first check what the stated size includes. Enter a laying module as-is. If you have actual rectangular stone dimensions instead, select Actual stone size and enter the joint gap separately.
Approximate coverage per piece = (actual length + joint gap) × (actual width + joint gap)
For example, an actual 3⅞ × 7⅞ in stone with a ⅛ in joint gives a 4 × 8 in module. Adding that joint again to the module would understate the paver count. The module method approximates a repeating field; it does not place partial stones at the perimeter or plan widely spaced stepping stones.
Mixed sizes and whole packs
For a multi-size pattern, use the manufacturer's coverage for the complete pack or pallet. Do not apply one small stone's area to every piece in the pack. The tool returns packs in this mode, not an invented count of each size.
A hypothetical pack covering 10 ft² needs 11 packs for 100 ft² with a selected 5% allowance: 105 ÷ 10 = 10.5. Purchased coverage is 110 ft²; 5 ft² comes from the allowance and another 5 ft² from whole-pack rounding.
How much extra should I allow for cuts?
Choose the allowance from your layout, product and cutting plan. Curves, diagonal edges, borders and spare stock can change it. Selecting a pattern name alone cannot establish the correct percentage. Use separate estimates when a border and field use different products.
Paver Base and Sand Quantities
Pavers, bedding sand and the base occupy different layers. Enter each layer depth from your project plan. Paver thickness is not bedding depth, and the cut allowance for stones does not enlarge the ground beneath them.
Layer volume (ft³) = footprint (ft²) × depth (in) ÷ 12
Layer volume (yd³) = volume (ft³) ÷ 27
Base volume uses the base footprint
The paver base calculator uses your entered depth and base area. If the base extends beyond the paved edge, use Base footprint area to include that extension. Otherwise it uses the paving area.
For an example 100 ft² footprint and 4 in entered depth, the geometric base volume is 33.3333 ft³ = 1.2346 yd³. This is not automatically the loose quantity to buy. If the depth describes a compacted layer, ask your supplier for the appropriate ordering conversion. No universal base depth or compaction factor is assumed.
Bedding sand is not joint sand
The paver sand calculator measures the bedding layer: 100 ft² at an example 1 in depth = 8.3333 ft³ = 0.3086 yd³. It uses the paving footprint and your entered depth; this example is not an installation specification.
To calculate paver sand for the joints, use the jointing product's coverage for your stone size, joint width and joint depth. Polymeric sand goes between the pavers, so the bedding-volume result cannot be used as its bag count. The Gator Maxx coverage table illustrates why joint geometry changes coverage. The bedding and polymeric sand guide shows where each material belongs in a cross-section.
Estimate Paver Patio Material Cost
For a paver patio cost estimate, enter your quoted price per paver or per complete pack. The tool multiplies that price by the whole units to buy, including the selected cut allowance and rounding.
Pavers-only subtotal = whole pavers or packs × price per matching unit
At a hypothetical $0.75 each, the 473-paver example costs $354.75. In pack mode, 11 packs at a hypothetical $25 per pack cost $275. These are examples for different purchase units, not current prices or a comparison of equivalent products.
The subtotal covers the pavers only. Base material, bedding and joint sand, edge restraints, labor, equipment, delivery and tax need separate quotes. It is not the installed cost of the finished patio.
Sources & Methodology
Area is calculated in ft². Non-overlapping areas are added before the selected paver allowance and a single whole-unit rounding. Actual-size mode adds one joint width to each dimension; module and published-coverage modes add none. Layer volumes use their own footprints and depths, with no automatic density or compaction factor.
1 ft = 0.3048 m; 1 ft² = 144 in²; 1 yd³ = 27 ft³. Example dimensions and prices are illustrative. Calculation method reviewed October 23, 2026.
