What Slope Should a Ramp Be for Accessibility?

Under the Americans with Disabilities Act, accessibility ramps became required for all public spaces. As the American population ages, ramps are becoming very common at private homes as well. Under the ADA and building code, there are limitations on the slope, width, total rise and run of accessibility ramps.

  1. Limits on Slope and Rise

    • The maximum slope for a ramp in new construction is one foot of rise for every 12 feet of run, or a 1:12 ratio. No ramp is allowed to rise more than 30 inches in total height.

    Landings

    • There should be a level landing at the top and bottom of every ramp. The landing should be the width of the ramp and at least 60 inches long.

      If an entrance is more than 30 inches above the ground, two or more ramps can be connected by landings. The landings must be at least 60 inches by 60 inches and be at least as wide as the ramps connected to the landing.

    Ramp Width

    • Ramps must have a minimum unobstructed width of 36 inches, according to federal law. Some states, including North Carolina, Washington and Wisconsin require wider ramps.

    Ramp Railings

    • Ramps must have railings on both sides of the ramp. If the ramp turns, the inside railing must be continuous. Railings should be between 34 and 38 inches above the ramp.
