Good planning is required to ensure that the stairs in the house do not become a risk of accidents. This is mostly done by experts. However, it is also advisable for builders or owners in the course of renovation measures to find out about staircase construction. The "bauen.de" portal provides information on how to calculate stairs and what to look out for when building stairs. For example, this must be based on the building regulations of the state building codes.
The three factors "riser height", "tread width" and "running width" are particularly important when calculating stairs. The rise height describes nothing other than the step height. According to "bauen.de", a step height of between 16 and 18 centimeters is safe and comfortable. The tread width describes the tread surface from the side. This should be 29 centimeters. The walking distance, on the other hand, refers to the area between the right and left edge of the stairs and should measure 80 to 100 centimeters.
Formulas are used to calculate these and other factors. For example, the formula for calculating riser height is “Exact Rise Height = Floor Height/Number of Treads”. To calculate the number of steps, the formula “number of treads = storey height/riser height” applies. In addition to these and other formulas, rules such as the step measure rule, the safety rule and the convenience rule also apply. In the article on the portal, interested parties can find out more about the topic and also receive a link to a stair calculator.
