It is suggested that if you put down a 3 to 4 inch layer of gravel then you will cover about 2 to 3 square feet.

Gravel is a rock that is of a certain particle size range. Specifically, it is any loose rock that is larger than 2 mm in its smallest dimension and no more than 64 mm. Gravel is an important commercial product, with a number of uses. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or tarmac. Russia alone has over 400,000 km of gravel-surfaced roads. Both sand and small gravel are also important for the manufacture of concrete.

Large gravel deposits are a common geological feature, being formed as a result of the weathering and erosion of rocks. The action of rivers and waves tends to pile up gravel in large accumulations. This can sometimes result in gravel becoming compacted and concreted into the sedimentary rock called conglomerate. Where natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, or basalt. Quarries where gravel is extracted are known as gravel pits. Southern England possesses particularly large concentrations of them due to the widespread deposition of gravel in the region during the Ice Ages.

There are many types of gravel below is a list of some different types:

Bank gravel: Gravel intermixed with sand or clay.

Bench gravel: A bed of gravel located on the side of a valley above the present stream bottom, indicating the former location of the stream bed when it was at a higher level.

Creek rock: This is generally rounded, semi-polished stones of a wide range of types. They are dredged or scooped from river beds and creek beds. It is also often used as concrete aggregate and less often as a paving surface.

Crushed rock: Rock that is mechanically broken into small pieces then sorted by filtering through different sized mesh.

Crushed stone: This is generally limestone or dolomite that has been crushed and graded by screens to certain size classes. It is widely used in concrete and as a surfacing for roads and driveways, sometimes with tar applied over it. Crushed stone may also be made from granite and other rocks. Also a special type of limestone, crushed stone is dense grade aggregate, or DGA, also known as crusher run. This is a mixed grade of mostly small crushed stone in a matrix of crushed limestone powder.

Fine gravel: Gravel consisting of particles with a diameter of 2 to 4 mm.
