No. 10 limestone gravel, called screenings, is available in about 1/8-inch pieces and is like a coarse sand. It makes an excellent base material for paving bricks and stones, and it is easily worked by hand; however, it is not suited for muddy areas. The most common gravel is No. 57, which is about 3/4 to 1 inch in size, or the size of a nickel to a quarter. Available as limestone and washed river gravel, the material is comfortable for driving and walking, which makes it excellent for topdressing surfaces, according to Three Z Supply.

No. 1 gravel has the largest stones, ranging from about the size of an egg to a softball, approximately 2 1/2 to 4 inches. Unless someone is moving them one stone at a time, they cannot be shoveled or worked by hand. No. 1 gravel is a poor packing material, unless smaller stones are combined with it or are used as topdressing, notes Three Z Supply. The stones are available as limestone and washed river gravel.
