Finding Projectors with the right Throw Distance

Once you've settled on the Resolution you want and you've got an ideal of how many lumens you need, the next question is a very practical one: which projectors will fit into your space and fill the screen you've got? You may already have a screen installed and know its exact dimensions. If not, you probably have a pretty good idea of the screen size you want. And you know your basic preferences for where you'd like to place the projector.

With that data it is easy to narrow down the list of projectors that will fit your space and screen size. Let's take an example. Say you've got a large conference room and you have a 170" diagonal 16:10 screen already installed. You've decided you want a WUXGA projector that puts out about 5000 lumens. Which projectors that have these performance criteria will fit your screen and throw distance?

To find out, go to the Projector Database. Select WUXGA in the Resolution list. Then enter a lumen range, say 4500 to 6000 lumens if you are looking for models that put out around 5000. Finally, enter 30 feet as your throw distance and 170" as your diagonal image size. Then click the "Find Projectors" button, and the search will show you all models that meet your stated requirements. The Database search results are initially presented in order of the projectors' popularity, but you can re-sort the list by price, by first ship date, or whatever other criterion you want.

Sorting by Throw Ratio

A more powerful way to use the Database is to sort by the Throw Ratio you want rather than Throw Distance and Screen size. Let's say you would be just as happy to place the projector anywhere from 24 to 36 feet from the screen, and you want to know which projectors will fill your screen from somewhere within that throw range.

This is easy. The Throw Ratio is simply the Distance divided by the Screen Width. Your 170" 16:10 screen is exactly 12 feet wide. So your Minimum Throw Ratio requirement is 24 feet divided by 12 feet = 2.0, and your Maximum Throw Ratio is 35 feet divided by 12 feet = 3.0. You just enter 2.0 and 3.0 into the Min and Max Throw Ratio boxes, and the Database will tell you every projector, and projector + lens combination, that will fill your 170" screen from somewhere between 24 and 36 feet throw distance.

I have two long throw Infocus projectors with a long through lenses. our screens are 110" and 53' ft distance in our church. We need to replace them with either new or used in our budget.Help

Ed, there's a lot more that goes into this decision than knowing screen size and throw distance. I suggest you get in touch with local integrator or contact one of our authorized resellers to talk you through it.
