Weight is an estimate (1.2-1.7 tons per cubic yard); actual weight varies with material and moisture.
For most decorative beds, a 2 inch layer covers the ground well. Larger river rock (2 inches and up) looks best at 3 to 4 inches so the soil does not show through.
Measure the area in feet, set the depth, and the calculator returns cubic yards, an estimated weight in tons, and a bag count.
