Getting a useful estimate
Each paver’s coverage includes its length, width and joint width. The estimate excludes cuts and edge courses.
Measure the space you need to fill. Rectangles use length and width; circles use diameter. For several sections, choose combined areas and add rectangles, then subtract exclusions. The final area must be greater than zero.
Check piece and pack coverage
Enter the rectangular paver dimensions and planned joint width. The calculator treats each paver plus its joint as a rectangle, applies your waste percentage and rounds up to whole pieces.
If your supplier gives coverage per pack, enter it to calculate full packs. Check the result against their layout instructions. The tool does not calculate individual cuts, edge courses, mixed-size packs or decorative patterns.
Volume formula
Allowance applies once to each volume layer. No density or compaction factor is assumed. If buying by weight, enter the density for your supplier’s product in the units shown.
A worked example
An example 10-foot by 10-foot rectangle filled 4 inches deep needs 33.333 cubic feet, or 1.234568 cubic yards, without allowance. A 10% allowance gives 37 cubic feet. These are arithmetic examples, not recommended depths.
Pavers, base and bedding sand
Enter base and bedding thicknesses from your project specification, then rectangular paver dimensions and joint width. A 10-by-10-foot area with 12-inch square pavers, zero joint and 10% paver waste gives 110 pavers. Mixed-size packs, cuts and herringbone need different coverage data.
Buying and checking quantities
Enter the volume printed on a bag, or its mass alongside supplier density. Counts round up to full bags. Costs use the purchasing unit and price you enter. Delivery is separate; labor and installation are outside this estimate. Copy or print your list to check with your supplier.
