10' high ins't that high when you have a projector hanging down...you'll be down near 8.5 feet at that point.

Most projectors are rated at 100" (diagonal) screen at 10-13 foot distance. Also, the further from the screen the less light gets to the screen.

for movies/photos a 'silver screen' (grey) is preferred.
For text and such white is a better choice.

So I'm hoping I can piggyback on this post with a scenario. My church has charged me with finding a video projection system for their parish hall. They have asked me to find a ceiling mount projector and screen system. The hall can go completely dark and has 10' ceilings. The hall is rectangular in shape and we are picturing the screen going against one of the long walls.
I'm proposing one of the electric screens that when not in use hides flush up in the drop ceiling. Does anyone have any expertise on screen choice as far as size, etc? I didn't realize that screen color (grey/white) was something to consider as well.
So far I am proposing the Optoma EH512 as a projector. It has a 16:9 aspect ratio, 5k lumens, and 15,000:1 contrast ratio. It is a DLP projector. The room is approximately 50'x80'.

I have an epson 2200 lumen one now. Going on ebay for $65. I'm using it as a test on a march wedding for a monogram. the bride is excited (i've known her 10 years, so this is a freebie/test/sample). See how it goes.

I'll sell you two 2200 lumen legacy projectors for $100 each(+S&H) 1-1.3 power zoom lens, power focus, remote, manual, and a pair of spare lamps. 720P or 1080i max and analog inputs compatible with UXGA, RGB, YC, & Cv. SHARP XG-NV6XU

Even got the perfect accesories for you:

Switcher scaler with DVI(HDMI input)
Distribution amp

So I double checked this morning. The ceilings are 11ft.
It's not a factor in anything other then the resultant length of the ceiling mount, or vertical offset.

Start with the audience - who is looking, where are they looking from, and are they seated or standing? Calculate the required screen size, and determine it's baseline relative to the audience. Choose a projector and lens able to align with the screen from the aesthetic position chosen for it's placement.

Every video installation starts with an audience. The projector is just and end result of a plan to be met, that thing you find at the end of a map.

None of that is true. (Well, it is when people go about it backwards,)
You don't start an installation by choosing a cheap fixed lens projector and then trying to make everything else in the space conform to it's limitations.
The projector can be mounted above the screen, and even attached to the same wall. It could be on the ceiling 2, 3, 4, 6..... even 65 feet away.

Distance is a function of the lens. Position is a matter of optics, and brightness a result of power. Screen surface is based on projection type and color reproduction.

The only obvious parameter with an eleven foot ceiling is that the maximum screen size is likely going to be 6.5' x 10' because any part of the screen below 48" from the floor would be obscured with a seated audience in a room with a level floor (as opposed to sloped auditorium seating.) This is why you start an installation by defining the audience rather than looking for projectors on Google.

It matters where the audience is - the projector, not so much.

I'd love to find an affordable indoor projector enclosure that hides the projector and protects its cables while being hung from the ceiling. I think we might consider a 150" diagonal screen.

What do you plan to project - 16x9 HD content or older 4x3 NTSC content?

Projectors have come a long way in the past 5-10 years.

Should be easy to find a nice 1080p (with decent lumens / contrast) for well below 1K.

Heck might even be able to pick up a (fake) 4K one for around 1K (Fake meaning not true 4K).

It's going to be underwhelming. I'd crank it up on a stand and get it as near to the projection point (dance floor?) as possible. If this is outdoors in sunlight, forget about it. Not even worth connecting.
