What size screen should I use?
For business presentation with graphs and figures the most distant
audience ought to be no farther from the screen than 8 times the height of
the projected image.
This distance can be extended to up to 14 times the height, if the text
is above minimum size, or if the presentation is entirely pictorial,
especially where the content is primarily for entertainment.
Alternatively use the follow table as rough guide.

Aspect Ratios Explained
The ratio between a screens' height & width is known as its'
"aspect ratio". It is important to have the correct aspect ratio
or the image will either be "cropped", with parts cut off
or you will be left with a "letter box" image with a
black area at the top & bottom of the screen.
