Paver Calculator
Estimate patio pavers, base gravel, leveling sand, and approximate material cost.
How this paver calculator works
The calculator divides the patio area by the area of one paver, then adds overage for cuts, breakage, and layout waste.
Base gravel and sand
The calculator estimates base gravel and leveling sand using patio area × depth. Local soil, drainage, climate, and project load can change final requirements.

Frequently asked questions
How do I calculate how many pavers I need?
Calculate the patio area, calculate the area of one paver, then divide patio area by paver area. This calculator also adds overage for cuts, breakage, and layout waste.
How much overage should I add for pavers?
A 10% overage is common for basic layouts. Complex patterns, diagonal layouts, borders, curves, and lots of cuts may require more.
How much base gravel do I need for pavers?
Base gravel is calculated from patio area multiplied by base depth. Many pedestrian patios use several inches of compacted base, but local soil and project requirements matter.
How much sand goes under pavers?
Many paver projects use about 1 inch of leveling sand over a compacted base. Always follow the paver manufacturer's installation guidance.
Can this calculator be used for irregular patios?
It is best for rectangular or square patios. For curved or irregular shapes, estimate the area separately and add extra overage for cuts and waste.
Do pavers need a gravel base?
Most paver patios and walkways need a compacted base to reduce settling and movement. Base requirements depend on soil, climate, drainage, and use.
Should I include joints between pavers?
For rough material estimates, paver dimensions usually get you close. Joint spacing, pattern, and edging can affect the final count.
How do I estimate pavers for a walkway?
Use the walkway length and width as the project area, then enter your paver dimensions. Add overage if the walkway has curves or cuts.
Are larger pavers easier to estimate?
Larger pavers may require fewer pieces, but they can be heavier and may create more noticeable cuts at edges. Layout still matters.
Should I buy all pavers at once?
For color consistency, it is often smart to buy enough pavers from the same batch or order, especially for visible patio projects.
How much sand goes under pavers?
Many paver patios use about 1 inch of leveling sand over a compacted base.
Does this work for curved patios?
It is best for rectangular areas. Curved or irregular patios need extra layout planning.
