Paver Calculator

How to use this paver calculator

1. Enter the patio's length and width, or switch to Total area for odd shapes you have already measured.
2. Enter the paver's actual length and width from the product sheet, or tap a published size. Add the joint width if your pavers are laid with a gap.
3. Set an allowance for cuts at edges, curves, and borders, and for breakage.
4. Optionally enter pavers per pallet to count pallets, and the base and sand depths from your installation plan.

How to calculate pavers: the formula, shown

Each paver covers its own face plus its share of the joint around it. Divide the area by that “module” area to get the number of pavers, add an allowance for cuts and breakage, and round up. If you buy by the pallet, divide by the pavers per pallet and round up again.

Default example. A 12 × 12 ft patio with 7.87 × 3.94 in pavers (the size Pavestone publishes for Holland Stone II 80mm), no joint width entered, a 10% allowance, and 384 pavers per pallet (Pavestone's published count for that product). Change the inputs above and the result panel recalculates; this worked example always shows the default.

Area        = 12 ft × 12 ft = 144 ft²
Paver area  = (7.87 ÷ 12) × (3.94 ÷ 12) = 0.21533 ft²
Pavers      = 144 ÷ 0.21533 = 668.73
Allowance   = 668.73 × (1 + 10/100) = 735.61 → 736 pavers
Pallets     = 736 ÷ 384 = 1.917 → 2 pallets

A check against the product sheet: Pavestone lists 83 sq ft per pallet for this paver, and 384 × 0.21533 ft² = 82.7 ft², which agrees. Base and sand layers are area × depth, converted to cubic yards by dividing cubic feet by 27.

How many pavers do I need for common patio sizes

Pavers for common patio sizes using 7.87 × 3.94 in pavers with no joint width, computed with the same formula as the calculator. The first count has no allowance; the second includes a 10% allowance, rounded up.

A wider joint lowers the count slightly; cuts at curves and borders raise it. Enter your own paver and joint sizes above.

Quick answers: how many pavers for common patios

Each answer is computed with the same formula as the calculator, using its default settings unless the question says otherwise.

What to order for a paver patio

For the default patio, buy 736 pavers: 2 pallets of 384. Partial pallets may be available; ask your supplier. How many pavers are on a pallet shows why the count and weight change with paver thickness.

• Pavers: order all of them from one production run if you can, so color matches across the patio.
• Edges and borders: a soldier or border course uses a different count. Measure the perimeter and calculate it separately.
• Base, sand, and joint sand: layer depths and joint products come from the paver manufacturer's installation guide. See planning a delivery for ordering bulk material.
• Odd shapes: split curves and L-shapes into simpler pieces with measuring irregular areas and enter the total area.

Patio paver base and sand: calculating the layers

Pavers sit on layers of base gravel and bedding sand. This calculator does not choose those depths, because they depend on the soil, the traffic the pavement will carry, and the paver manufacturer's installation guide. Enter the depths from your plan and it computes each layer's volume.

For example, if a plan called for a 4 in base and a 1 in sand layer under the default 12 × 12 ft patio, the layers would be 1.78 yd³ and 0.44 yd³ before compaction. Those depths are illustration only, not a recommendation.

Compacted gravel takes up less room than the loose gravel delivered, so ask your supplier how much extra to order. The gravel calculator adds an allowance and rounds to supplier increments.

Tips for measuring a patio or walkway

• Measure to the outside edge of the finished paving, including any border.
• Use the paver's actual dimensions from the product sheet. A nominal “4 × 8” paver can be slightly smaller.
• Raise the allowance for herringbone or diagonal patterns, which need more cuts along the edges.
• Keep a few spare pavers for future repairs; matching later can be difficult.
