impact screen size and projector placement

[greenstreak]

I have a height limit of 90 inches for my screen due to garage door tracks and would like to know how wide I need to make the screen. I want to have the image cover the complete screen. My second question is can you move the projector back. If it needs to be at 6ft from the screen can I move it back to 7ft and still get the same result?

This site may help you with the calculations. http://www.projectorcentral.com/proj...ulator-pro.cfm
For my projector there is a range of distance that I can place the projector from the screen due to it's zooming functionality.
Hope that helps!

I assumed you already have a projector...If you don't yet have a projector go here: http://www.projectorcentral.com/projectors.cfm
You can select specs for what you looking for in a projector...as well as put in your throw distance and your vertical image.
