Recommended Image Size

Whenever possible, the size of your audience should help determine the size of your projected image. An image that is too small or too large can be difficult to see and lessen the impact of your presentation. Use the following chart as a guideline for image size based on audience size.

Screen Location & Distance

The following items represent the ideal set-up for screen location and distance for most presentations.

• To prevent obstruction of the screen by viewers heads in the front, the projection screen should be positioned so the bottom of the screen is at least 36 inches above the floor. If possible, we recommend 48 inches above the floor.
  
• The Distance from the screen to the first row of viewers should be equal to 2X the width of the screen.
  
• Screen height should be 1/8 of the distance to the farthest viewer (or the distance from the screen to the farthest viewer should be 8X the image height).
  
• The maximum seating width should equal the distance to the screen.
  
• The best viewing is generally within a 60 degree cone from the center of the projection screen.
