How big of a screen would a typical projector make at 15 feet away
Answer
Most projectors have zoom capability meaning you can adjust the image size. You need to look at this specification on any projector you are considering and determine if it will work for your intended screen size and throw distance. Also you need to consider the projector brightness and screen gain requirements. A good resource for making these determinations can be found here... http://www.projectorcentral.com/JVC-DLA-RS25U-projection-calculator-pro.htm Just select the projector you are considering and then use the calculator to determine if it will work.

I want to buy a projector? How do I know which one is better?
Mutual Hel
When one buys a computer, one looks for the computer's hard drive, RAM, CPU, and so on.
What about when it's a projector? What should I look for? LCD or DLP?
Answer
Projectors range from $600 to $250000 in the consumer arena. It's hard to figure from your question, but here's a couple ideas. Most theater projectors range from $5000 to $40000.
The battle for best display is being fought between 3 chip LCoS and 3 chip DLP. If you have limited lighting control in your room, the DLP is a better choice. You will need the extra driving force of the DLP to overcome the ambient light. If you have good control over light, the LCoS (similar to LCD only much better) will deliver the smoothest, most realistic picture. 3 chip LCoS is actually cheaper than 3 chip DLP which makes it an even nicer choice. Look at JVC.
Single chip DLP has a high speed motorized color wheel inside. Any time you add electromechanical devices to electronics, you diminish reliability.
Other things to look at:
Contrast ratio
We can't distinguish light to dark beyond 2000:1 at any given moment, but over time our eyes can adjust as high as 20000:1. So, a near black screen that immediately goes 20000 times brighter at once will "clip" our sensors in our eyes, but we will eventually adjust to it.
Brightness, measured in ANSI lumens, lux or candellas per sq. meter. Higher is generally better.
Throw distance is important to figure screen size and location
Bulb replacement cost
Loudness of the cooling fan
Formats: 2.35:1 is a nice addition to the standard 16:9 since most large production films are shot in it. Also, film is 24 frames per second instead of video's 30 fps. (or it's multiples.) It's good if the projector can switch back and forth.
Resolution: 1080x1920 native is the standard now.
Calibration: The better projectors can be set to D65, or 6504 kelvin for white. This is important for accurate display. There are minor variations on this theme. Check with a calibrator you trust.
If you're looking at projectors under $5k, you won't find most of what I'm recommending so keep an eye on the contrast and brightness, and the practical issues mentioned above.
Don't forget the popcorn machine!
