Selecting a Projector Screen & Surface
The Final Click 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 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.

For additional help in selecting screens, we recommend and invite you to contact our facotry trained sales consultants at 800-329-6506 opt 2.  We can take the guess work out of selecting the correct screen size and surface for your Home Theatre or business needs.

Four Steps to Selecting the Right Screen
  1. Pick the type of screen that best suits your particular needs. For example, choose from front projection screens 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.
  2. 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. The Final Click recommends the following formula for determining screen size:
    * 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.
  3. Select the appropriate format for your projection application. Common formats are as follows:

    Common Applications Aspect Ration
    Width/Height
    NTSC Video 1.33
    PAL Video 1.33
    HDTV Video 1.78
    Letterbox Video 1.85
    Cinemascope 2.35
    35 MM Filmstrip 1.32
    2x2 Standard 35MM Double-Frame Slides 1.50
    SXGA 1.25

  4. Choose the screen surface that best suits your projection and viewing requirements. For your convenience, below we have listed descriptions and performance characteristics for each front and rear screen surface. If the screen will be used for multiple projection methods, choose the screen surface that meets the requirements of the lesser performing projection method.

How to Calculate a Custom Screen Size

Use the following formulas to calculate a custom size. The formulas will assist you in finding the viewing area only.

NTSC (1.33) HDTV (1.78) Leterbox (1.85) SXGA (1.25)
Video Format Video Format Video Format Video Format
Diagonal/1.667 = Height Diagonal x 0.49091 = Height Diagonal x 0.4762 = Height Diagonal x 0.625 = Height
Height x 1.33 = Width Diagonal x 0.87247 = Width Diagonal x 0.88 = Width Diagonal x 0.78125 = Width
Width/1.33 = Height Height x 2.0395 = Diagonal Height x 2.10 = Diagonal Height x 1.60 = Diagonal
Height x 1.667 = Diagonal Width x 1.14585 = Diagonal Width x 1.135 = Diagonal Width x 1.28 = Diagonal
  Height x 1.78 = Width Height x 1.85 = Width Height x 1.25 = Width
  Width x 0.561837 = Height Width x 0.5405 = Height Width x 0.80 = Height

Screen Borders and Drop

Black masking borders are standard on most front projection screens at no extra charge. Borders enhance the perceived brightness of an image on a screen. The human eye perceives the image to have more contrast and a sharper picture with brighter colors. Borders also allow the projected image to "bleed-off" the screen for professional appearing presentations.

Additional border or "Drop"  is also available on most of our wall, ceiling and electric screens. Drop is extra fabric added to the top or bottom of the screen to adjust the screen surface to within normal viewing heights. Drop can be specified in either black or white.

Note: Tensioned electric screens are standard with 12" black drop at the top in all sizes except for 200" diagonal which is standard with 2" black drop.
