How the paver calculator works
Enter the length and width of the project area, then enter the face dimensions of one paver. The calculator divides the project area by the area covered by one paver and adds the waste allowance you select.
Formula
Project area = length × width
Paver area = paver length × paver width
Pavers to order = ceiling(project area ÷ paver area × (1 + waste percentage))
Example
For a 12 ft × 20 ft patio using 6 in × 6 in pavers with 10% extra: the project area is 240 sq ft, one paver covers 0.25 sq ft, and the estimated order quantity is 1,056 pavers.
Assumptions and material notes
This estimate treats the project as a rectangular area and uses the paver's face dimensions. It does not account for cuts around curves, borders, patterns, joint width, broken pieces, or installation-specific layouts. Use a suitable waste allowance and confirm the final quantity with your supplier.
Frequently asked questions
Does the calculator include paver joints?
No. Enter the actual face dimensions of the paver. Joint width can change the layout and final count, especially on larger installations.
How much extra should I order?
A common planning allowance is around 5% to 10%, but complex patterns, many cuts, curves, or future replacements may justify more.
Can I use different paver sizes?
Yes. Enter the length and width of the paver you plan to use. For mixed-size patterns, calculate each component separately.
Does this calculate the base material?
No. This calculator estimates paver units only. Base, bedding sand, edge restraint, and jointing material should be estimated separately.
What if my project is not rectangular?
Break the project into simple rectangles or other measurable sections, calculate each section separately, and add the quantities together.
