Projector throw distance is an important consideration in designing your home theater and picking your projector but what is it.

Throw distance is simply the distance from the front of the projector to the screen. That seems pretty simple but there are some things to consider. Each model of projector has different optics and will create a different size picture form a certain distance back.

So first you have to measure the room you are using. where do you want the projector to go? Is it going to be ceiling mounted in the middle of the room? Is it going to be further back in a separate room. How big a picture are you trying to make? I have said before that I suggest you actually get the projector first and then determine the picture size. But in some cases you are going to want to know more precisely how big the image is going to be based on that projector location.

One of the best resources is projecotrcentral.com. They have a throw distance calculator for each projector and you can compare. You can also see how that projectors zoom lens will affect the picture size.

A few models have as much as a 2X zoom so that gives you a lot of options in placing the projector. My projector only has 1.25X zoom but you would be surprised at how big a difference that actually is. Also mine is a powered zoom. So you are much more likely to use the zoom if you can simply press a button on the remote.

Another thing to keep in mind is the brightness. If you are trying to make a very large picture you will need a projector that is rated higher on brightness. Most models have several brightness settings. Brighter settings for watching Tv in a lit room and dimmer for a more film like look and to extend bulb life.

So do some research on throw distance. If you have a limited room and want a big picture you might be disappointed if you have your heart set on one model only to find out it can't fill your screen from that distance.
