All of our porches are 9' long.

You will also need the porch frame in order to use this porch as it is not included.

You can view the A-Frame style porch frame here: http://www.cylinderstoves.com/porch-aframe-p-54.html

You can view the internal porch frame here: http://www.cylinderstoves.com/frames-c-23_31.html (you'll have to scroll down a bit and then select the proper size)
