How do you find the angle of elevation for a wheelchair ramp?

  • For example: the ramp is 3 feet above ground leve. It goes up .5ft, then 1ft, then .5ft again and the up 1ft, again. if thakes sense

  • Answer:

    Use the concept of rise/run as is employed by builders of roofs & stairways. Here you have a rise of 3' so if the wheelchair can handle a rise of 1' in a run of 3.5' then the ramp should start 3 x 3.5 or 10.5' from the porch.
