How far apart should the spacing of rungs be on portable ladders?

The correct spacing for the rungs on portable ladders is 12 inches apart. This spacing is standard to ensure safe and comfortable use for individuals who might be climbing or descending the ladder. When rungs are spaced too far apart, it becomes difficult for users to maintain their footing and can increase the risk of accidents, such as slips or falls, especially when working at height.

The 12-inch spacing allows for proper ergonomics and accessibility, accommodating a variety of user heights and preferences. It meets the safety regulations set in place to provide stability and ease of climbing. Maintaining a safe distance between rungs is critical in enhancing the overall safety of ladder usage in construction and other fields, thereby reducing the risk of injuries.
