To work out how far back from the screen you should place the projector, you will need to find out the width of the image you want to project.
Typical screen sizes that we offer are:
|Screen size (measured diagonally)
||Approximate screen width
Next you’ll need the throw ratio. This can usually be found in the product specifications on our website, the manufacturer’s website, or the projector’s manual.
The throw ratio will usually be two numbers, for example 1.4 - 2.2 : 1. These are the throw ratios when the projector is zoomed in and out.
To work out how far back from the screen the projector will be, take the width of the screen, for example 2m (a 92-inch screen), and times it by both of these numbers:
1.4 x 2 = 2.8m
2.2 x 2 = 4.4m
Therefore, in order to project onto a screen 2m wide (92-inch diagonal), the projector would need to be between 2.8m and 4.4m back. You can then use the zoom and focus to get it perfect.
If you don’t fancy working out these calculations, visit us in-store and we’ll do it for you.
