Good planning is required to ensure that the stairs in the house do not become an accident hazard. This is usually done by experts. However, it is also advisable for builders or owners to find out about staircase construction in the course of renovation work. 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 "rise height", "tread width" and "tread 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 centimetres is considered safe and comfortable. The tread width describes the tread area from the side. This should be 29 centimeters. The tread width, on the other hand, refers to the area between the right or left edge of the stairs and should measure 80 to 100 centimetres.
Formulas are used to calculate these and other factors. For example, the formula for calculating the pitch height is "Exact pitch height = storey height/number of steps". The formula for calculating the number of steps is "number of steps = storey height/pitch height". In addition to these and other formulas, rules such as the step size 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.
