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 to whole pavers.
area = length × width × quantityarea = π × (diameter ÷ 2)² × quantitypaver length × paver widthceiling(total area × (1 + waste percentage ÷ 100) ÷ paver area)paved area × layer depth × (1 + layer extra percentage ÷ 100)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.
Using the illustrative entered value of 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 using the editable 1 in bedding-depth example requires 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. The initial 10% is an editable project assumption; no pattern automatically changes it.
The initial 500-piece package value is an editable example, not a universal pallet or box quantity. Enter the selected product's count or coverage.
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 and uses physical paver area without joints. Joint width affects only the optional grid comparison, which assumes one rectangular section, a straight grid, uniform joints, no complex edges, and no offcut reuse; both orientations are shown.
Enter product-specific pieces or manufacturer coverage per unit. Whole-package rounding is reported separately from cutting waste.
The initial 1 in bedding depth, 4 in base depth, and their 5% extras are editable project assumptions. Layer volumes use area-times-depth geometry; CalcRocket does not determine suitable materials, layer depths, compaction, drainage, or pavement structure.
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 the selected product's pieces or coverage per pallet and the calculator rounds upward.
Enable bedding and enter a depth and separate allowance appropriate to the project. The initial value is editable, not a design requirement.
Enable base material and enter a project-specified depth and allowance. The calculator does not design the pavement base.
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.
CMHA distinguishes pavers, bedding course, base, drainage, and pavement-design responsibilities. Its guide is a specification resource, not a universal depth or package rule for every project.
