Paver Calculator
Convert project square footage into individual pavers and retail packs. Enter the actual face dimensions and a waste rate suitable for the layout.
Compare up to three scenarios
Capture the current result, change one or more inputs, and see the options side by side. The first option becomes your baseline.
Your live calculator remains unchanged. Capture it only when you want a comparison point.

View all saved project estimatesWhat does the paver calculator calculate?
Divide project area by one paver’s actual face area, add pattern and cutting waste, and round up to whole pieces or packs. This estimates field units only. Border courses, contrasting bands, curves, stairs, spare stock, base aggregate, bedding, and joint material need separate planning.
Paver pieces and full packs
Paver dimensions in inches are converted to square feet by dividing square inches by 144. Project area divided by face area gives pieces before waste, then pack count is rounded up separately.
How to measure for an accurate estimate
- Measure the finished paved surface, not the outside edge of excavation or restraints.
- Use actual face dimensions or manufacturer coverage for the exact product.
- Split curves and irregular shapes into simple areas, then combine them without overlap.
- Measure borders and accent bands as separate linear or area quantities.
Rectangular paver patio
An 18 ft by 12 ft patio uses 8-by-4-inch pavers, 120 pieces per pack, and 10% waste.
216 sq ft requires 972 pavers exact; with waste, 1,070 pieces or 9 full packs.Before you purchase material
- Choose a waste rate that reflects pattern, curves, edge cuts, mixed modules, and future repairs.
- Confirm square feet and pieces per pack because multi-size packs may not divide evenly.
- Order one color blend and mix units from several packs during installation.
- Estimate compacted base, bedding, edge restraint, joint sand, drainage, and delivery separately.
Common questions
How many pavers are in one square foot?
Divide 144 square inches by one paver’s face area in square inches. An 8-by-4-inch paver covers 32 square inches, so 4.5 pavers cover one square foot before joint or pattern adjustments.
How much waste should I add for pavers?
About 5% may suit a simple running bond in a square area, while 10% is a common planning allowance. Curves, diagonals, herringbone, mixed sizes, many cuts, or desired repair stock can require 15% or more.
Does paver spacing change the quantity?
Yes. Manufacturer coverage often includes the designed joint width, while multiplying actual stone face dimensions does not. Prefer the product’s published square-feet-per-pack coverage for interlocking systems or mixed modules when available.
Does this estimate include the patio base?
No. It estimates surface pavers only. Base aggregate and bedding depend on excavated area, compacted lift thickness, soil, drainage, climate, and application. Calculate those volumes separately and follow the pavement system’s installation specification.
