What is the angle of a wheelchair ramp?

The angle of a wheelchair ramp should ideally be no steeper than 1:12, meaning for every inch of vertical rise, there should be at least 12 inches of ramp run. This translates to an approximate angle of 4.76 degrees. For safety and accessibility, the angle can be adjusted to be less steep, especially for longer ramps. Local building codes may also specify particular requirements for ramp angles.
