How far apart in centimeters should the rungs of a fixed ladder be placed?

The proper spacing for the rungs of a fixed ladder is 30 centimeters apart. This distance is deemed optimal for safety and usability, ensuring that users can comfortably place their feet while climbing or descending the ladder. A spacing of 30 centimeters permits a secure grip and stable footing, minimizing the risk of slipping or losing balance.

While 25 or 35 centimeters might seem reasonable, they do not align with standard safety practices that prioritize ease of use and stability. Similarly, a distance of 40 centimeters is too wide, potentially increasing the risk of falls or accidents when using the ladder. In the context of ladder safety and construction guidelines, consistency and adherence to established standards are essential for the protection of users.
