If you are putting the screen on the 16' wall, then your seating will be about 11' eyes to screen, so about a 110" to 133" diagonal would be typical depending on where you like to sit in a theater. The video above is correct, but in recent years I've found over and over and over that people actually like to go slightly, to significantly larger than typical recommendations. So, the professional recommendation is dated at this point. So, there is no 'perfect' size without first knowing where you are going to sit, and also where you like to sit in a movie theater.
If you like sitting a bit closer in a theater, then a 120" diagonal may be the sweet spot. If you like sitting really close, then go to 133" diagonal. If you like sitting more towards the back/middle, then a 110" diagonal is correct.
Screens are measured in diagonal typically, not height and width. And you MUST get a 16:9 screen. So, 8'x4.5' is fine, but really, that's a 110" diagonal 16:9 screen, which is a common size.
If sitting at 11', I would probably get the 120" diagonal if I wasn't sure. I've had a 106" diagonal I viewed from 12' away, and I absolutely believe that it was too small.
For where to mount the projector, you must first pick the projector.
Assuming the TW5300...
Now go here:

Set the image diagonal to the size of the screen you will use (I will say 120" diagonal), and you will see the Throw Range is between 10'8" to 12'10". The 'default' distance is in the middle of that range at 11'8", but you can have the LENS TO SCREEN distance anywhere between that 10'8" to 12'10".
If your mounting the screen on the 16' wall, and the projector is mounted 12' away, against the back of the room, then your lens to screen distance will actually be about 11' lens to screen. That's pretty tight for a 120" diagonal, but it does work.
