About Gravel Calculators
Gravel Calculators is a free collection of online estimators for builders, landscapers and homeowners who need to know how much material a job takes. It covers gravel types such as #57 stone, 304 gravel and crusher run, along with concrete, sand, mulch, earthwork, masonry, roofing and lumber.
Users pick a calculator for their project, such as a driveway, French drain, shed foundation, patio or post holes, and enter dimensions. The tools return volumes in cubic yards, weights in tons or kilograms, and bag or truck counts, using stated density assumptions.
What sets the site apart is its breadth: one hub covers many job-site materials and conversions, and each calculator notes the planning assumptions behind its numbers so users can judge the estimate for their own project.
