projector screen placement

if I go the projector route this is the only wall I can put a projector screen. ceiling height at this side of the wall is 11 ft (it is 8 ft on the opposite). would it strain my neck if I put a motorize projector at the top? Im getting black out blinds and most likely only use the projector at night.

most roll down, electric or manual, will have a certain amount of 'black masking' at the top. If you double check this spec before buying, you should be able to find a screen with 2 or 3 feet and then you can easily pull the screen down to eye level even with the housing mounted at the 11ft ceiling.

i would personally say, as a rule of thumb to try to have the bottom of the screen no higher than eye level. I find having my eyes level with about 1/3rd of the way up from the bottom of the screen to be very comfortable for both seated and reclined viewing. but anywhere between those points would work for me.

the best way to tell is to try it for yourself though. your seats, your neck, your viewing distance, etc can all play a significant role. ultimately nobody on here can tell you what's comfortable for YOU, i can only say what is comfortable for ME.

Thanks for the response!

So the projector can throw the image from 11ft ceiling down to eye level ?

the vertical image shift would depend on what projector you get. I feel like i'm over generalizing, but most home theater projectors need to be placed somewhere between the top and bottom of the screen. Many data projectors come with more of an offset to allow them to be mounted higher (or lower) than the screen. The projector in my classroom is mounted like 12' but projects onto my white board at about 8'(top)

there are a few things you need to make sure are all compatible to make this work
THROW DISTANCE
-how far the projector is from the screen. the farther the throw distance, the larger the image will be. most projectors have at least a little zoom give you a size range at any given throw distance
ZOOM
-provides a range of image sizes at a given throw distance. For example, at my current position, my projector can zoom anywhere from about 140" to 85"
"IMAGE OFFSET' (in quotes because i'm not sure what the proper name for this is)
-most projectors are designed to be place near the top or bottom edge of the screen, not directly in the middle. the amount the image is shifted up/down from center is the offset. typically there is no horizontal offset, only vertical
LENS SHIFT
-allows you to shift the picture up/down or left/right (change the offset). cheaper projectors have pretty limited, sometimes no lens shift at all. this makes them a lot more of a challenge to mount perfectly

all of the above things can be different in different projectors. So when you're looking at models, be sure to check these things to ensure you can project the right sized image to the right location from your desired throw distance.

start off my figuring out where you'd like your projector to be. try to pick a spot directly in the middle of your screen location (horizontally). When you know what height and throw distance that will be, then you can start figuring out how big you'd like the image, and people can start recommending projectors that can provide that. Or alternatively, if you're flexible with the projector mounting, pick a screen size, research some projectors, then you can figure out where those projectors need to be mounted in order to project the desired image

i think if you want to get more specific help, you'll need to provide info such as a budget, what content you intend to watch, details about the room like color and whether or not there will be any light

Comfort level for screen height varies depending on seating position and personal preferences. For example, if you sit upright in a chair you would prefer a lower screen height than if you viewed while leaning back in a recliner. All of the formulas you might see for screen height are based on averages and are not applicable to all. It's always best to experiment and find out what works best for you rather than what works for others who may be different from you. The suggestion to get a screen with extra black drop is good for adjustability. Another option is to experiment by projecting on the wall, finding the right height for your personal preference and then buying a screen to fit that image height. As others have noted optimum projector mounting height will vary depending on screen height.
