Gravel specifications for a dry landscape rock

Quick answer：

Karesansui, also known as 'dry landscape,' is a Japanese Zen garden style that uses rock arrangements to represent mountains and bodies of water without using water elements. The gravel specifications for a karesansui rock landscape typically include the size of the gravel, which is usually between 1/8 to 3/8 inches in diameter, and the type of gravel, which is often river rock or pea gravel. The gravel is used to cover the ground and create a smooth, flowing surface that mimics water currents and the movement of waves.
