What are the Different Gravel Sizes? (with pictures)

Aug 04, 2020· The smallest of all gravel sizes is usually size #10, which is also commonly known as screenings gravel. This gravel is typically around 1/8th of an inch (0.32 centimeters) in diameter, making it similar in appearance to coarse sand. Often, screenings gravel is used as the base for bricks, paving stones, and other similar items.
