Gravel Calculators

Gravel Calculators is a collection of free online tools that help you estimate the exact amount of gravel needed for driveways, paths, French drains, post holes, and paver bases. Users input dimensions for various shapes—rectangular, triangular, or circular—and the calculators return precise volume and weight estimates for different gravel types, from pea gravel to recycled concrete aggregate.

Designed for homeowners, landscapers, and contractors, the site reduces material waste, prevents costly shortages, and speeds up project planning. Each calculator accounts for specific gravel densities and supports multiple measurement units, making it suitable for projects of any scale.
