Ideal Screen Size for Theater? 2.35:1 or 16:9?

For you screen guys out there...

My dimensions are 16x43ft and part of that space is a pool table and full bar.  I will have one row of theater seating about 13-15 feet from the screen.  I am looking to mount and recess (hide) the screen in the rafters.  My question is this, what brand should I use? and what size screen should I get?  The screen will go across the 16 ft span. Projector is undetermined at this point but will be a good one.  The windows in the area can be "blacked out" I am also thinking of doing an acoustically transparent screen.  Thoughts? 

Also, should I do 16:9 or letterbox? I will use it about 75% for TV and sporting events and 25% on movies.

Thanks,
mgould

Auxinput clearly knows his stuff so this is more a question than a recommendation from me, but I was thinking..  I have a 100" screen and 1080p projector that I bought for a project a couple years ago.  While it's OK, the one thing that pops into my head is that it looks like you're doing a dedicated theater room, aren't there specific paints that you could use on your viewing wall that allow for any size and format and thereby essentially "future-proof" the room?

Only raising this question since if I were to set up a dedicated dated HT room for projected video, I would want to research this option thoroughly.  

Aren't there great paint options available these days for larger screen viewing sizes that rival physical screens?

Would love to know.

I remember reading about usage of different paints about 5-6 years ago.  I think it was over on AVSForum.  I never did any experimentation with paints.  You might not have the amount of gain that a specific screen material would have (I don't know).  Also, you would have to make sure you used a perfectly flat surface.  Many residential houses nowadays have textured walls.

One thing to keep in mind is that you really need to have a border or some way to black out the entire area surrounding the screen.  There is much light that would reflect off the front wall, event though the projector is primarily aimed at the screen.

As for projector, I am looking at the sonys, epsons and wolfs.  I am not opposed to using other brands but they are the ones I am most familiar with.  Sony is what I would really like due to the fact that they are 4k but their cost is somewhat out of control.  But the main fact is that I am looking at 2000 lumen+ if I can afford it.

Greg- 
I have seen some theaters projected on the painted walls.  They don't look that bad.
These are my reservations with white painted walls for projectors.
You are limited to white.  If you want to paint your other walls a different color, the one you project on would have to be white. It would look odd to me.  Also, I'm sure the white paint used would not look good in a room as it would look very sterile like a hospital.

I did some calculations. My screen is 52" X 92", which equals 33.2 square feet of screen area. In a completely dark room, my 1000 lumens projector is just enough for my 1.3 gain screen after calibration (calibration will actually reduce some light output because projectors typically push the blue to make it brighter).

If you put up a 11 foot wide screen, it’s going to be 68 square feet (11 x 6.1875), which is twice as much area. With the reduced 0.9 gain of the Greyhawk, you will actually need a very bright projector, something towards 3000 lumens. This could limit your choice of projector (as many choices are only 2000 lumens) or push your cost a lot higher.

Reducing the screen down to 9 feet wide (108" x 61-3/4") would reduce the area to 45.5 square feet. Move your seating to about 13-14 feet away. This option would allow you keep the 2000 lumen projectors as options.
