Da-Lite - Projection Screen Surfaces




Da-Lite offers a wide array of screens each with a choice of projection surfaces. Selecting the right combination to meet your needs is important for optimum results. The following recommendations offer guidelines for selecting a screen that suits your application. Although these recommendations will work in most situations, each must be looked at not as a strict rule, but rather as a guideline for determining your actual needs based on your own situation.

Four Steps to Selecting the Right Screen

1. Determine the optimum screen size based on room dimensions, planned audience seating size and arrangement. The rule of thumb is to fit the screen to the audience - not to the projector.

Da-Lite recommends the following formula for determining screen size for commercial and educational applications:
  • Screen height should be approximately equal to 1/6 the distance from the screen to the last row of seats, allowing text to be read and detail to be seen in the projected image. Ideally, the first row of seats should be approximately two screen heights away.
  • The bottom of the screen should be a minimum of 4 feet above the audience floor, allowing those seated toward the rear of the audience to see the screen. This may require additional screen "drop" for ceiling hung screens.
Da-Lite recommends the following formula for determining screen size for home theater applications:
  • Screen height should be approximately equal to ¼ the distance from the screen to the last row of seats. Ideally, the first row of seats should be approximately two screen heights away.
  • The bottom of the screen should be a minimum of 2 feet above the audience floor. This may require additional screen "drop" for ceiling hung screens.

2. Select the appropriate format for your projection application. Common formats are as follows:

Common ApplicationsAspect Ratio - Width:Height
NTSC Video1.33:1
PAL Video1.33:1
Wide Format1.60:1
HDTV Video1.78:1
Letterbox Video1.85:1
35 MM Filmstrip1.32:1
2x2 Standard 35 MM Double-Frame Slides1.50:1
Super XGA Computer1.25:1
Cinemascope2.35:1

3. Choose the screen surface that best suits your projection and viewing requirements. If the screen will be used for multiple projection methods, choose the screen surface that meets the requirements of the lesser performing projection method.

4. Pick the type of screen that best suits your particular needs. For example, choose from front projection screen in either portable, wall or ceiling mounted models in either manual or electric versions or rear projection screens. Generally, if your projection application is permanent, then wall and ceiling screens are your best choice. If, however, you find your needs require moving the screen to different locations then a portable screen is a better alternative.
