The slope ratio of a handicap accessible ramp shall be a maximum of?

The maximum slope ratio for a handicap accessible ramp is 1 foot in 12 feet. This guideline is set to ensure that the ramp is not too steep, which can be challenging for individuals with mobility impairments to use safely and comfortably. A slope of 1:12 means that for every inch of vertical rise, there should be at least 12 inches (or 1 foot) of ramp run, allowing for a gradual incline that makes it easier to navigate.

This particular slope is widely recognized and often mandated by the Americans with Disabilities Act (ADA) and other accessibility standards, providing a balance between accessibility and the physical effort required to ascend or descend the ramp. A steeper slope, such as 1:10 or any steeper option, would increase the difficulty and safety risks for users, while shallower slopes, like 1:14 or 1:16, might be fine but are not the necessary standard to ensure compliance and safety.
