What does this calculator estimate?
This calculator estimates the number of pavers you need for your project based on your area dimensions, paver size, and a built-in waste allowance. It also calculates the volume of base material and sand required, using the depth you enter. Use the paver count to order your pavers, and the volume result to purchase the correct amount of base and sand for installation.
How this calculator works
Formula
Pavers = ceiling(area / paver area) x (1 + waste); base aggregate (yd3) = area x base depth / 27; sand (yd3) = area x sand depth / 27.
Worked example
A 20 x 12 ft patio with 8 x 4 inch pavers and 10% waste: 1,188 pavers, 2.96 cubic yards of base aggregate at 4 inches, plus 1 inch of bedding sand.
Sources
Sources support the method, terminology, or planning context. Editable assumptions remain your responsibility.
Assumptions to verify
- Paver dimensions are nominal face dimensions and joints are not separately modeled.
- Base and bedding depths are uncompacted planning inputs.
- Edging, joint sand, drainage, labor, and delivery are excluded.
Frequently asked questions
What is a paver calculator and how does it work?
A paver calculator is a browser-based tool that estimates the number of pavers and amount of base material you need for your project. You enter your area dimensions and paver size, and it instantly calculates the results right in your browser—no signup required.

No. The paver calculator is completely free, no-signup, and runs entirely in your browser. Your measurements are never stored or shared.
How accurate is the paver calculator for my project?
The paver calculator gives a reliable estimate based on your entered dimensions and paver size. For best results, measure your area carefully and add a 5–10% overage for cuts and waste.
