How Much Gravel for a 10x20 Area?
For a 10x20 area of gravel at 2 inches deep, you need about 1.23 cubic yards - roughly 67 bags (0.5 cu ft bag), about 1.73 tons. The amount changes with depth; the table below shows common depths, and you can adjust everything in the calculator.
Based on a 10x20 area (200 sq ft). One cubic yard = 27 cubic feet; bags are 0.5 cu ft bag.

You need about
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.
