Shucks! Sorry I missed your post first time around. Glad you are happy with your projector. SUPER Bowl,,,what Super Bowl. Half time show was best part. I know this is a GTO forum but if anybody else is planning a home theater, I can offer the following advice.
I work in the audio/video industry designing systems for corporate, government and higher education.
Let’s start with screen size. How far is the farthest seat from the screen? For example, if your theater is 20’ deep, the viewer farthest from the screen may be about 19’ away. To determine minimum screen size, divide 19’ by 6 to determine screen height. 19/6=3.166 feet or 38” high.
The projector should be able to project full 1080p resolution. This is the resolution you will get from Blu-ray and even Netflix is now made 1080p resolution available.
The 1080p aspect ratio (ratio of width to height) is 16:9. So a 38” high screen would be 67.5” wide (77.5” measured diagonally). I know, it doesn’t sound very big but it would be big enough. Here is a good screen size calculator:

Perhaps you only have one row of seating, say a couch. That would represent the farthest fewer seating position. I suppose you could go bigger on screen size but I would not go TOO much bigger.
Projector brightness is also important. Does the room have good light control? Can you darken the room in the middle of the day? As long as you are able to darken the room, I would buy a projector with about 2500 to 3000 lumens light output.
You also need a good projection screen. A painted white wall will not give the quality image you want. Put up a real projection screen with a matt white surface.
I like DLP based projectors over LCD based. Here is a link to great recourse for the projector shopper.
