Choosing the right projector screen......

What is the resolution of your chosen projector?

This will enable the selection of the correct aspect ratio for the projection screen that will best suit the application. For example, if a computer with Powerpoint or Computer Video is needed then perhaps a 16:10 native aspect ratio would be the correct choice, or if a DVD player is needed then 16:9 will be required.

Example of aspect ratios:

- 1:1 Overhead and opaque projection
- 4:3 (1.33:1) Computer data & video
- 16:9 (1.78:1) High Definition television HDTV
- 15:9 Native computer format
- 5:4 (1.25:1) High - end data graphics
- 1.85:1 Widescreen (also known as letterbox)
- 2.35:1 Cinemascope

Throw to width ratio for your chosen projector?

The installation of the projector in relation to the projector screen (throw distance) is related to the throw to width ratio that the lens / projector combination can achieve. Room dimensions are key to this. A useful tool in determining this information is Projector Central who have a comprehensive calculating tool for a huge range of manufacturers and products.

What are the dimensions of the room?

Determining the size of the projection screen viewing area in relation to the first audience position for business / education environment should be approx. 1.5x the viewing area height away, as a rule of thumb. Height of the viewing area should be approx 1/6th the distance of the furthest audience position. So the room dimensions are important in ensuring a screen viewing area size that can have text read easily by all the audience members, providing comfortable viewing.

What is the height of the ceiling?

The correct height from the floor to the bottom of the viewing area in a business environment for a 16:10 aspect ratio screen is between 100cm to 120cm and in a Home Cinema project with 16:9 this should be between 90cm to 110cm depending on the seating height. This ensures that the audience comfort is maintained for the duration of the showing. With this in mind, the ceiling height will also play a crucial part in the maximum width of viewing area that will actually fit into the room and still be comfortably positioned.
