Stairs incorporate three pieces of geometry: rise, going, and pitch. The rise is the height between steps, the going is the step itself {technically, the distance between the leading edges, or nosings, of two successive steps measured horizontally}, and the pitch is the overall steepness of the stairway.
The design of stairs consists of three fundamental geometric elements: rise, going, and pitch. The rise refers to the vertical distance between each step, while going defines the step's horizontal depth. Specifically, it measures the space between the front edges, or nosings, of two adjacent steps. These measurements are crucial for ensuring safety and comfort when using stairs.
Additionally, pitch describes the overall angle of the stairway, which influences how steep...
