Paver Count (Rectangle)
units = area / ((paverLength + spacing) × (paverWidth + spacing)). The spacing adds to each dimension of the paver module, reducing the number needed.

About this calculator
What this does
Estimates the number of pavers needed for a patio or walkway project, accounting for spacing between units, waste, circular and triangular layouts, and mixed paver sizes. Also calculates required materials including gravel, bedding sand, joint sand, and edging, with retailer package planning for Lowe's, Home Depot, Menards, or custom pricing.
Who it is for
Homeowners, landscapers, and contractors planning paver patios, walkways, or driveways. Useful for material takeoffs, budgeting, comparing retailer pricing, and avoiding under-ordering or over-ordering pavers.
How it works
The calculator divides the total patio area by the effective area of a single paver (including spacing) to get the unit count. Spacing expands the paver module, so fewer units cover the same area. Circle and triangle areas use their respective geometric formulas. Mixed sizes are handled by assigning each paver type its own area within the total. Waste percentage is added on top of the raw count.
Limitations
Does not account for complex patterns like herringbone or basketweave that change effective coverage. Retailer presets are editable defaults, not live pricing. Slope grading, base compaction, and drainage considerations are outside the scope of this estimate.
Formula
Circle Area
area = π × radius². The calculator uses the circle area formula and adds the circle waste default on top of the user's waste percentage.
Spacing Adjustment
A spacing gap of g inches increases the effective paver module from L × W to (L + g) × (W + g), which compounds the reduction in total unit count across the full area.
Material Quantities
Gravel volume = area × gravelDepth, bedding sand volume = area × sandDepth. Joint sand is estimated per square foot and edging is the total perimeter length.
How it works
Step 1
Choose your patio shape
Select Rectangle, Circle, Triangle, or Mixed Sizes to match your project geometry.
Step 2
Enter dimensions and paver size
Input the patio length and width (or radius for circle), then set your paver dimensions, spacing gap, and waste percentage.
Step 3
Add mixed sizes (optional)
If using different paver sizes, add rows for each size and assign an area percentage or square footage to each type.
Step 4
Select a retailer
Choose Lowe's, Home Depot, Menards, or Custom to get package counts and pricing based on that store's typical pack sizes.
Step 5
Review the material sheet
Check the total pavers, packages, gravel, sand, edging, and budget estimate. Use the printable material sheet for your shopping list.
Reference ranges
Standard Paver Sizes
Common paver sizes include 4×8 in (brick), 6×6 in, 12×12 in, and 24×24 in (large format). Larger pavers cover more area faster but are heavier to handle.
Spacing Gap
Typical paver spacing is 1/8 in to 3/8 in for sand-set joints. Wider gaps are used for polymeric sand application or rustic looks. Spacing beyond 1/2 in may need more joint sand.
Waste Allowance
A 5-10% waste factor is standard for rectangular patios. Circular patterns, curved borders, or mixed sizes may require 10-15% waste to account for cutting.
Material Depth Guidelines
Gravel base: 4-6 in for pedestrian patios, 6-8 in for driveways. Bedding sand: 1 in. Joint sand: fills flush to paver surface after compaction.
