\n Thank you for your question. While this ramp can be used on stairs, there are limitations. The “pitch” of stairs is generally much steeper than ramps (think of wheelchair ramps outside of buildings), so placing the ramp over the top of stairs will make it too steep to use. If the staircase only consists of a few steps, then the ramp might work but the bottom of the ramp must be placed farther out than the bottom step. The average “height” of individual steps (known as the “rise”) is 7-8 inches. By referring to the “recommended height” figure for a given ramp, you can determine how many steps can be covered safely. It's always best to measure the rise (height) and run (length) of the area involved to make sure the ramp will work in your particular situation.\n
