Cubic yards and tons of gravel for a path, patio or driveway.
AdvertisementA 20x10 ft area covered 4 in deep needs about 3.5 tons of gravel.
We multiply length by width by depth to get the volume in cubic yards, then multiply by a typical gravel density of about 1.4 tons per cubic yard. Weight varies with stone type and moisture.
About 2 in for a decorative layer or path topping, 4 in for walkways and patios, and 4 to 6 in over a compacted base for driveways.
Roughly 1.4 tons (2,800 lb) for typical gravel, ranging from about 1.2 to 1.5 tons depending on stone size and moisture.
About 58 sq ft at 4 in deep, or about 116 sq ft at 2 in, for typical gravel at 1.4 tons per cubic yard.
For paths and decorative areas, yes: it keeps weeds down and stops the gravel from sinking into the soil. Driveways need a compacted base of crushed stone instead.
