Modular staircase provides a way to travel between two points with different heights. A stair consists of a riser and a tread. Stair step determines the height of the steps. The tread staircase is where you place your feet. The general rule of thumb is to tread modular staircase plus twice the height of the path should correspond to 26 inches. The width of the steps on the use of stairs.
Rise and Run
Measure the rise and run of the stairs to calculate your stair dimensions. The increase is the change in vertical height, and run is the horizontal distance will cover the stairs. Landings are used when the run of the stairs is longer than the width of seven or eight stairs. Turns on the stairs used when the increase is more than running.
Stair risers and stair height gauge must be maintained consistently over stairs. Our brains know stair height after the first step. This allows us to go up the stairs without looking at our feet, or focus on the task. People are triggered if the climbing height changes. Most building codes allow for only a small variance — less than a quarter of an inch — in the trails above the stairs.
Large public buildings, such as museums and courthouses, are designed with wide treads with short risers. This is done for visual effect and to accommodate more people on the modular staircase. However, should liven not be less than 4 inches, because people generally cannot adapt their gait to a shorter rise.
