River Rock Weight Calculator

A cubic yard of river rock typically weighs between 2,400 and 2,700 pounds (1.2 to 1.35 tons). The exact weight depends on rock size and moisture content—smaller, tightly packed rocks weigh more per volume than larger ones with air gaps.

For decorative landscaping, use 2-3 inches of river rock over landscape fabric. For pathways with foot traffic, go 3-4 inches deep. Drainage applications may require 4-6 inches depending on soil conditions.

Measure your area in square feet, then multiply by depth in feet to get cubic feet. Divide by 27 to convert to cubic yards. Most suppliers price river rock by the cubic yard or ton.

Yes, smaller river rocks pack more densely with fewer air gaps, resulting in more weight per cubic yard. Large rocks (4-8 inches) weigh about 2,400 lbs/cu yd, while small rocks (0.5-1 inch) can reach 2,700 lbs/cu yd.

A standard half-ton pickup can safely carry about 1,500-2,000 pounds (0.75-1 ton) of river rock. A full-size truck with heavy-duty suspension can handle 2-3 tons, but check your vehicle's payload capacity before loading.
