If you're asking about the distance between storm door edge and the wall it would be about 9" If you're talking about the distance of the storm door fully open then it's about 46"

Hinge towards the walkway. The other way, you always have to open the screen door wider and walk around it to get in.. Could be a pain. What is the distance between the door and the window wall?
Out of my mind and out of control!
