To comply with regulations, the maximum ramp rise per step should not exceed which measurement?

The maximum ramp rise per step is set to ensure accessibility and safety for individuals using ramps, particularly those with mobility challenges. A rise of 6 inches per step is a common standard in various building codes and accessibility guidelines, including the Americans with Disabilities Act (ADA). This measurement provides a balance between ease of use and the structural feasibility of ramps.

When the rise is limited to 6 inches, it allows for a more manageable ascent or descent, making it less physically taxing for users while also promoting stability. Steeper rises can pose safety risks, potentially leading to falls or requiring more effort to navigate, which goes against the intent of providing accessible environments.

In contrast, other higher rise measurements would make ramps more challenging to traverse, which does not support accessibility goals. Therefore, maintaining the 6-inch maximum rise aligns with best practices in design for accessibility.
