Gravel Calculator

About Gravel Calculator

This free online tool helps homeowners, landscapers and contractors estimate how much gravel or stone a project needs. It is built for driveways, paths, patios, decorative beds and drainage trenches, and works from a rectangle, a circle or a known area, with extra areas for irregular shapes.

Users pick a material such as pea gravel, crushed stone, driveway gravel or limestone, and the calculator converts the volume into cubic yards, cubic meters, US short tons and covered area. Depth presets for common jobs are included, and optional bag size and unit price fields turn the result into a bag count and rough material cost.

What sets it apart is the focus on turning volume into weight, which is how many suppliers sell stone. Density defaults for each material can be overridden with a quarry or bag figure, and the page explains the formulas and typical depths for each use.
