Formula used
Units = ceil([project area ÷ coverage per unit] × [1 + waste ÷ 100])
Worked paver example
Paver Calculator example: 330 ft² × 1.1 = 363 ft² of order coverage. Dividing by 0.23 ft² per unit gives 1,578.26 units, so the purchase quantity is 1,579 whole units.
Package rounding and usable yield
Round to whole pieces and then to the supplier's bundle or pallet quantities; count border and field pavers separately if they differ.
Paver units are only the surface course
Use the pack or pallet coverage for the chosen paver and laying pattern. Border courses, curves, diagonal cuts, mixed sizes, and breakage affect the whole-unit allowance. Base aggregate, bedding sand, joint sand, edge restraint, and drainage layers are separate quantities and should be estimated with their own dimensions and tools.
Why the label value may not match the floor or wall
Pattern, border courses, curves, diagonal cuts, blended bundles, and unavailable partial pallets change the count to buy.
Questions specific to this calculation
What usable coverage should I enter for paver?
Enter the net paved area and the exposed face area of one paver or the manufacturer's stated pieces-per-square-foot coverage.
