I was thinking 16:9, since that's the format of the projector.
Throw Distance? Should be no more than 15' -3" from the "Screen" (not wall)
You may want to place the PJ back inside the Hallway. ( that would be cool )
You guessed it! I calculated the max screen size at just over 150" with room behind the screen and the projector in the hall with the lens in-line with the rear walls.
Have you settled on aFrame Plan?
You posted a 150" 16:9 plan in another thread that looked simple enough. My current 120" non-AT screen is painted WO cloth on a modular aluminum frame, but I'm handy with wood, too, and need an excuse to buy more tools.
With just the right Window Masking Curtains and suppressed colors on the Wall, "rear lighting" behind the Screen. If this is a AT applications, it would be good to know what exactly your speaker plans.
I'm installing blinds that do a pretty good job at blocking light, and can add drapes if I need to make it absolute, though for the windows behind the screen, any light leakage might serve well as back-lighting. I'm thinking about a dark blue for the walls and a neutral grey for the ceiling and carpet.
I'm still rocking my SVS 16-46 PC subwoofer and Swan Diva 5.1/C3/R3/2.1 7.1 speaker setup from almost 20 years ago. I'm looking around at DIY speaker options for the Atmos speakers and possibly to replace the Swans (see "excuse to buy more tools" above).
Have you determined how your going to hold the Screen in place?
That's part of why I was concerned about whether the back of the screen needs to be sealed off to exclude reflections. My plan (which hasn't had a lot of thought put into it, to be honest) is to have two vertical posts (wood or a pair of compression fit, telescoping shelf supports I have from some Ikea utility shelves) upon which I would hang the screen. I'd line the posts up with a pair of the vertical braces in the screen frame.
