Estimate physical paver count, cutting allowance, pallets or boxes, simple grid layout, bedding sand, base material, perimeter, and optional paver cost.
Each paving section is normalized to square meters and summed. Recommended area applies the selected cutting allowance once.
Physical paver length times width gives paver area. Recommended area divided by physical paver area is rounded upward using the shared purchase-unit helper.
area = length × width × quantityarea = π × (diameter ÷ 2)² × quantitypaver length × paver widthceiling(total area × (1 + waste %) ÷ paver area)paved area × layer depth × (1 + layer extra %)ceiling(pavers ÷ pieces per package), or ceiling(recommended area ÷ package coverage)A 20 × 15 ft patio is 300 ft². An 8 × 4 in paver is 0.222222 ft². With 10% waste, 330 ft² requires 1,485 pavers.
At 500 pavers per pallet, 1,485 pavers require 3 pallets, purchasing 1,500 pavers with 15 additional from package rounding.
A 25 m² area with 200 × 100 mm pavers and 10% waste has 27.5 m² recommended area and needs 1,375 pavers.
A 300 ft² patio with 1 in bedding uses 25 ft³ or 0.925926 yd³ before its separate extra allowance.
Joint spacing does not enlarge physical material area and is used only for the optional grid layout.
Cuts, pattern, breakage, edge shape, and offcut reuse vary. No pattern automatically changes waste.
Paver cutting waste does not inflate bedding or base material; each enabled layer has its own allowance.
The area method is the primary purchase estimate. The optional layout assumes one rectangular section, a straight grid, uniform joints, no complex edges, and no offcut reuse; both orientations are shown.
Enter pieces or manufacturer coverage per unit. Whole-package rounding is reported separately from cutting waste.
Layer volumes reuse the shared area-times-depth geometry and canonical volume conversions. Preset values are not presented as universal design requirements.
Perimeter is shown only for one rectangle or circle. It does not assume every edge requires restraint and is omitted for combined sections where edges may be shared.
Optional paver cost supports piece, package, or displayed area pricing. It excludes labor, excavation, delivery, equipment, edge restraint, drainage, joint sand, and taxes.
Divide waste-adjusted paved area by one physical paver's area and round upward.
Divide one square foot by physical paver area in square feet.
Larger physical paver area generally reduces count for the same paved area.
Joint width affects the simple grid layout, not physical paver area used by the primary purchase estimate.
It depends on layout, edges, pattern, breakage, and reuse; adjust the editable allowance.
Yes. Circular sections use π times radius squared.
Enter pieces or coverage per pallet and the calculator rounds upward.
Enable bedding and enter project depth plus its separate extra allowance.
Enable base material and enter its depth and separate allowance.
Complex patterns may require more cuts, but no automatic universal waste adjustment is applied.
No. Reliable joint-sand quantity needs product and joint-depth information.
No. Optional pricing is paver material only.
