How much ramp do I need to go up three stairs?

The Americans with Disabilities Act (ADA) provides specific guidelines for the construction of handicap ramps. According to the ADA, the slope of the ramp should not exceed 1:12, which means that for every inch of rise, the ramp should be 12 inches long.
Assuming that each step has a rise of 7 inches, the total rise for three steps would be 21 inches. Therefore, a ramp for three steps should be at least 252 inches (21 feet) long. However, the actual length of the ramp may vary depending on the available space and other considerations.
The ADA also provides guidelines for the minimum width of the ramp, which is 36 inches, and the landing size, which should be at least 60 inches long and as wide as the ramp. The ramp should also have edge protection in the form of curbs or railings to prevent wheelchair users from falling off the sides.
It's important to note that state and local building codes may have additional requirements, so it's recommended to consult with a licensed contractor or local building department to ensure that your ramp meets all necessary regulations.
