What is the Stair Calculator & How does it work?
The Stair Calculator is a tool designed to help architects, builders, and homeowners determine the essential dimensions of stairs, including the number of steps, riser height, and tread depth. These calculations are crucial for ensuring that stairs not only meet aesthetic standards but also comply with building codes and safety regulations.To calculate these dimensions, you need to input the total rise (the vertical distance from the floor of the lower level to the floor of the upper level) and the total run (the horizontal distance covered by the stairs). The number of steps is typically determined by dividing the total rise by a standard riser height. Once the number of steps is known, you can calculate the tread depth by dividing the total run by the number of treads.
n = \frac{R}{r}
n = number of steps, R = total rise, r = standard riser height
