Does projector distance matter?

The projector to the screen distance does matter. In fact, it is a very important element in planning your home theater. By definition, the further the projector is from the screen, the larger the image will be. However, it is not just having the projector to the back of the room to get the largest image possible. The further the distance between the projector and screen, the less bright the image will be.


Screen Types

Projector Screen can be fixed on the wall, or projector screen pull down (or retractable screen). For households wanting to replicate the theater atmosphere, the fixed screen is the way to go. However, if you do not have a dedicated TV room, you might want to use a retractable projector screen; if you are not watching TV, you can fully retract the screen and you will not even notice you have a projector set up in the room.

The retractable projector screen can be manual operated or motorized. Both have the same performance. The only difference is the way you will pull down and retract the screen.

How Big Should The Screen Be?

The answer is, as big as you can get! When using a projector at home size does matter. Large screen will allow you a fully immersive experience. The screen should cover most of your field of vision.

Before choosing your screen, you need to decide on the screen ratio. Home theater screens are 16:9, which is the ratio of broadcast and streamed TV. 2:4 ratio is the format of movies. The 16:9 ratio is the most popular in the households in Australia.   

For a 16:9 screen, a 30 to 35 degree viewing angle is recommended. The greater the viewing angle the closer to the screen you need to be sitting.
