Enter the size of the area and the depth of gravel to find the volume, the weight and the cost.
Works for driveways, paths, drainage beds and more.
The volume is the area multiplied by the depth. A 20 by 10 foot area covered 3 inches deep is 200 square feet times 0.25 foot, which is 50 cubic feet, or about 1.85 cubic yards. The calculator shows the volume in cubic yards, cubic meters, cubic feet and liters.
Gravel is sold by weight as well as by volume. The weight is the volume times the density of the material. Loose gravel weighs about 1,680 kilograms per cubic meter, which is about 105 pounds per cubic foot. Sand, wet material, and gravel mixed with sand are heavier or lighter, so pick the closest material or enter your own density.
Gravel settles and packs down after it is spread, so order a little extra, often 5 to 10 percent. Delivery yards usually sell by the cubic yard or by the ton. If you buy by the bag, enter the bag size to see how many to buy.
Multiply length by width by depth, all in feet, and divide by 27. For 20 by 10 feet at a depth of 0.25 foot, that is 50 divided by 27, or about 1.85 cubic yards.
About 1.4 to 1.5 short tons, or around 2,800 to 3,000 pounds, depending on the stone and how wet it is.
A driveway usually needs 4 to 6 inches, a path 2 to 3 inches, and a drainage bed anywhere from 6 inches to a foot.
Yes. Add 5 to 10 percent because gravel compacts after it is spread.
Pick the circle shape and enter the diameter. The area is pi times the radius squared.
