ok so i want to make a projector home theater. my question is how big of a screen should i get. like L x W. the distance from the projector will be roughly 10-10 1/2 feet and this is the projector i want.

if you look guys its also the higher res not just the 640x480
Answer
First, save your money. That projector is a 640x480 resolution (roughly half the resolution of a low end high definition projector) and the native format looks like it's 4:3 (~square). This means you will be watching a low resolution screen, and when you want to watch something in widescreen, it will likely reduce your resolution even further in order to achieve the correct wide format.
Next, your throw distance is fine at ~10 feet, but with a projector you want to balance room light with screen size. The larger the projected screen, the darker the room has to be. If you want a 100" screen, you will need to be TOTALLY BLACK because this projector doesn't have a lot of brightness, but at the recommended 72", you can have some ambient light in the room, it will just wash out the picture.
Once you've determined screen size, and controlled ambient light, you will have to continually recalibrate your projector (correct brightness and color) because as the bulb ages, it's color and brightness output will vary, and negatively impact your watching experience, and you should look at the cost of replacing the bulb as you'll be doing it every ~2000 hours (or less!)
I generally don't recommend projectors for amateur home theater hobbyists because of all the sacrifices and additional investments that are generally required for the projector to function properly. If you want to do it right, expect to pay no less than $5-7000 dollars for projector and room modification to make the experience worthwhile.
Buy a direct view screen unless you have a dedicated room you can make into a home theater, with controlled lighting, a dedicated audio system (the speakers in the projector will be terrible!) and the capability to run wires through the walls and ceiling to make for a clean install.
*Edit*
As mentioned below, the projector scales resolutions down. It is native at 640x480 and that's all it will ever be able to show. It can take in any resolution, but isn't capable of actually SHOWING those resolutions, it just removes information (detail) from the image until it can display whatever is left. This is not an investment I would recommend making, you will be sharply disappointed. Beyond the low resolution, it's a fair bet that the lens is very low quality (poor focus edge to edge, poor detail) the fan is likely very loud (interrupts your movie experience) and as mentioned above, if you plan on using the internal speaker... good luck. It will sound terrible and have zero bass capability.
IF all you ever plan to do is watch standard DVD's or play video games, this unit might function minimally to suit your needs, but it is NOT capable of displaying high definition. You need a projector with a NATIVE RESOLUTION of at least 1280x720 (720p) to be capable of displaying high definition.
Hope this helps!

What LED (portable) Projector?
Faddi A.
::::Someones Experience::::
Well Iâve concluded after a lot of search that LED projector should atleast be 60 lumens, 500-1 to 1000-1 contrast and should have USB or SD card slot. LED projectors brightness level is somewhat better than the conventional lamp based projectors so anything in the range of 100 lumens in enough. Also the biggest advantage of 20000 to 30000 life hours :-D I am now a happy owner of 'Samsungs sp-p410m' LED projector which is absolutely brilliant. Couldnât find it online in UK so ordered one from Korea :p yep i liked it that much :p it has SVGA 800 x 600 resolution, brightness 170ANSI, 1000-1 contrast ratio and 80 inch projection which looks stunningly bright, vivid and crisp on my not so white wall. oh and it has digital keystone correction too :-D inputs are VGA, composite & USB. its around 750$ but worth the money as it will last for 10 to 15 years. I recommend following in order, but plz give specs a LONG good look:
1-Samsung sp-p410m
2-Benq gp1
3-Toshiba TDP-F10
5-Samsung sp-400
4-Acer K10
Please give your suggestions or share your experience.
Thanks

Led projectors are very dim... the dimmest on the market. Only useful in a very dark room, & small screen. Resolution is no better than DVD resolution or worse on most of them, except the most expensive.
Led projectors are nowhere near as bright as the dimmest lamp-based projectors. Typical popular normal projectors boast 1600-4200 lumens with a contrast ratio of 2000:1.
LED projectors are 10-60 lumens... About the brightness of a very dim penlight flashlight, & very poor contrast ratios. Brighter ones are just now coming out, but still not good or bright enough to be practical.
For the price, you can get a 1600-2700 lumen DLP projector with a 2000:1 contast ratio. They're small enough to fit at least 2 in 1 backpack.
I typically fit 2 small DVD players, mixer, a laptop, & 1 of my DLP projectors in a backpack.
LED projectors are a portable novelty or toy for those with a disposable income, & not really very useful or practical yet. Wait a few years for the technology to get better.
From my experience with super bright LEDs, & the specs on them, is they grow dimmer with age long before their "lifetime" is up. How useful will that dim overpriced projector be if it's grown too dim to barely be seen after 3,000-5,000 hours?
Notice the LED display on your alarm clock, DVD player or VCR has grown too dim in just a few years?
