What width is the desired screen size?
Are the images you are projecting going to be in wide-screen (16:9),
Standard (4:3) or a custom size?
To best fit the proposed display area and the images that will be projected,
will screen be mounted portrait or landscape?

16:9 Wide-Screen Aspect Ratio
4:3 Standard Screen Aspect Ratio
Lookup the LLM (light level multipler) and multiply by the
ASM (Ansi/Sq Metre) to find the desired ANSI Lumens required
For example a 67” DarkVue Screen has a LLM of 2.0 for use indoor with ambient
daylight - the ASM is 2000 - Therefore the minimum recommended ANSI lumen projector
required is 2.0 x 2000 = 4000 Ansi
To calculate the Lens Throw ratio - select your screen size - look up the width of the screen
measure the distance from the screen to a suitable location for the projector (so that people
cannot walk in front and disrupt the image) - Divide the Distance by the Width of screen.
For a 50” 16:9 Screen where the projector will be 1000mm from the screen
1000mm / 1016 = .98 - therefore the lens throw ratio should be less than .98:1

1.5 - 1.8:1 Ratio
If you know the throw ratio of the projector, multiply the distance Ratio x Width of screen
to get the distance required. A 50” 16:9 screen using a .57:1 ratio short throw projector
1016mm width x 0.57 Ratio = 579mm distance from projector lens to screen.
