How many tons will 2in to 4in rock cover?

To determine how many tons of 2-inch to 4-inch rock will cover a specific area, you first need to calculate the volume of the area in cubic feet or cubic yards. Typically, one ton of rock covers approximately 1.5 to 2 cubic yards, depending on the size and density of the rock. As a general estimate, for a depth of 2 to 4 inches, one ton of rock can cover about 80 to 100 square feet. Thus, you would need to calculate the total area you wish to cover to find out the total tonnage required.
