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

• A. 1 foot in 20 feet
• B. 1 foot in 12 feet
• C. 1 foot in 10 feet
• D. 1 foot in 8 feet

Answer: (B)

Wheelchair ramps must not be too steep, so their slope is limited to a comfortable, pushable incline. The standard maximum is a rise of one foot for every twelve feet of run—a 1:12 ratio. This keeps the ramp doable for most users while keeping the overall length reasonable. Steeper options (like 1:10 or 1:8) are harder to propel and often not allowed for public or commercial installations, while a gentler slope (1:20) exists but is not the maximum. So the highest permissible slope in typical requirements is 1 foot in 12 feet.
