How much wall do you really need?
Do not stop at the image width. Add the screen frame, mounting tolerance and enough side clearance to assemble and level the frame. If you use front speakers, leave enough space that the screen does not force them into corners or block them.
Furniture and projector height matter
With UST projectors, a larger image usually moves the projector farther from the wall and pushes the image higher. The screen may fit the wall while the projector fails to fit the furniture geometry. Use your projector's official placement chart for the intended image size.
Measure twice: a wall that is “about 11 feet wide” is not automatically enough for a 130.7-inch-wide image plus frame and installation clearance.
