What angle is often considered too steep for a stairway?

A stairway angle of 45 degrees is often considered too steep for comfortable and safe use. Building codes and safety guidelines generally recommend stairway angles not exceeding this degree. When stairs are built at steeper angles, it can lead to difficulties in ascending and descending, increasing the risk of falls and accidents. A 45-degree incline can require significant effort to navigate, particularly for individuals with mobility challenges.

Typically, an ideal angle for stairways ranges from about 30 to 35 degrees, providing a safer and more accessible pathway. Angles greater than this, like 40 degrees and beyond, can contribute to an experience that many might find uncomfortable. Therefore, while it's possible to construct stairs at 45 degrees, it is often avoided to ensure user safety and comply with recommended guidelines.
