I've been looking for a projector screen for my home theater and have been looking at a 16:9 screen. After playing around with the numbers, a 16:9 screen is about the size of the room from ceiling to floor at ~190". So that's the absolute max screen size. With an acoustic screen, I can hide the speakers behind it so then speaker placement isn't a problem.\n\nIf I went with a cinemascope screen, it'd be closer to a more-reasonable 5.5' tall for the same width, but then the screen is going to still be about wall-to-wall.\n\nI'm wondering, how large is too large? Is it too large to be going wall-to-wall? If I only have one couch, is floor to ceiling height okay or should I work with a narrower cinemascope screen or a smaller 16:9?\n\nWith my UST projector in another room, I've noticed some light-bleed on the ceiling because I have the screen about 3" from the top. In this dedicated space, I could easily put black velvet or curtains around that space to reduce reflections.\n\nHow much space should I really give around the screen?
