Base depth (in)

Base depth only; paver thickness is not included.

Before you buy: Base requirements vary with soil, drainage, climate, paver type, and expected loads. This calculator estimates the volume for the base depth you enter; it does not determine excavation depth, bedding sand, edging, or structural specifications.

How the estimate works

Patio area is calculated from the selected shape. Paver count is area divided by one paver's face area, rounded up, with your chosen allowance added. Base volume is patio area multiplied by the entered base depth; it excludes compaction and bedding layers.

Frequently asked questions

How many pavers should I buy?

Estimate the patio area, divide by the face area of one paver, then add a reasonable allowance for cuts and breakage. Pattern, joints, and edge cuts can affect the actual quantity.

Does the base volume include sand?

No. The estimate uses only the base depth you enter. Bedding sand, jointing material, and other layers need separate calculations.

What waste allowance should I use?

It depends on the pattern, patio shape, number of edges, and paver type. More cuts or a complex layout may require a larger allowance.
