Does the cantilever length of a canopy affect its ability to shelter from the rain?

The cantilever length of the canopy will directly affect its rain shelter effect. The cantilever length refers to the distance that the canopy extends outward from the main structure of the building (such as the wall). This length determines how much area the canopy can cover and protect, which in turn affects the effectiveness of rain shelter.
Specifically, the longer the cantilever length, the wider the coverage area of the canopy, which can effectively block rainwater and prevent it from directly dripping onto the areas that need to be protected (such as doors, windows, walls, pedestrian walkways, etc.). This can not only reduce the erosion of buildings by rainwater, but also provide a relatively dry walking space for pedestrians.
However, the longer the cantilever length, the better. An excessively long cantilever may increase the load on the structure, affecting the stability and safety of the building. Meanwhile, excessively long cantilevers can also increase construction costs and complexity. Therefore, when designing canopies, it is necessary to comprehensively consider the setting of cantilever length based on factors such as the actual situation of the building, climate conditions, and functional requirements.
In summary, the cantilever length of the canopy is one of the key factors affecting its rain shelter effect, and it needs to be reasonably set while ensuring safety, economy, and practicality.
