What is/are the factor(s) in projectors that govern how far the screen can be & how big is the image from an A4 page w.g a Word doc or a Powerpoint frame.
Also, what governs how bright & clear the image is

The distance of the projector from the screen depends on its "throw" See click here#. There are short throw projectors around which can be placed very close to the screen.

A large amount depends on where it is to be used and for what eg ambient light conditions, size of audience.
