How thick should the paver base be?

For patios and walkways, a compacted base of 10-15 cm (4-6 in) of crushed stone or gravel is standard. The calculator uses 10 cm for the base volume estimate; add more for driveways or heavy vehicle traffic.

Do I need joint sand on top after the pavers are set?

Yes. After the pavers are set, joint sand is swept into the gaps and compacted to lock the pavers together. The calculator includes joint sand volume in its estimates.

What is the recommended sand bedding thickness?

The sand bedding layer is typically 2.5 cm thick. Sand bedding thicker than about 3 cm can shift and let pavers settle unevenly; it should be screeded level.

How is paver waste calculated?

Users set a waste percentage (default 10%). The calculator multiplies the paver count by (1 + waste percentage) to account for cuts and breakage during installation.

About this tool

What Paver Calculator does

The Paver Calculator on SmartCalc estimates the materials needed for outdoor paving projects by calculating three components: pavers, a compacted gravel base, and a sand bedding layer. Users enter the patio length and width, paver dimensions, joint width, and a waste percentage to receive results that include paver count, base gravel volume, bedding sand volume, sand bag quantities, and a cost estimate covering both pavers and sand. The tool is designed to prevent under-ordering by accounting for material waste and standard construction practices.
