Weight is an estimate (1.25-1.7 tons per cubic yard); actual weight varies with material and moisture.

For decorative ground cover and walking paths, 2 inches is usually enough. For a driveway, build it in layers: a coarse crushed-stone base of 3 to 4 inches, then a finer top layer.

Measure length and width in feet, set your depth, and the calculator returns cubic yards, an estimated weight in tons, and a bag count.
