Free Paver Calculator – Pavers, Base & Sand Quantities

Calculate how many pavers you need for patios, walkways, and driveways. Estimates gravel base, sand setting bed, and polymeric joint sand.

How to Calculate Paver Materials

To estimate pavers, divide the total area by the area of one paver and add a waste factor. Standard 4×8 inch brick pavers cover about 0.22 sq ft each, so a 100 sq ft patio needs roughly 450 pavers plus 5–15% waste depending on the laying pattern.

A proper base prevents sinking and shifting: install 4–6 inches of compacted gravel for the sub-base, then 1 inch of sand as a setting bed. Use polymeric sand in the joints (about 1 bag per 80 sq ft) to lock pavers and resist weeds and erosion.

Pattern matters for waste: herringbone at 45° requires up to 15% extra material from diagonal cuts, while running bond, basket weave, and stack bond need only 5%. Always buy 10% extra for future repairs — matching pavers from the same production run ensures color consistency.
