If the screen's height is 54 inches and the audience is viewing documents with a 3 Percent Element Height, what is the distance to the Farthest Viewer?

To determine the distance to the farthest viewer given a screen height and a specified element height percentage, one must first understand how to calculate the appropriate viewing distance based on visual ergonomics.

In audiovisual design, a common guideline suggests that the distance from the screen to the audience should be approximately 10 to 12 times the height of the viewing element. In this scenario, we have a screen height of 54 inches, and we are calculating for a 3 percent element height.

First, we find the element height based on the 3 percent figure:

• Element Height = 3% of Screen Height

• Element Height = 0.03 x 54 inches = 1.62 inches

Next, to find the recommended distance for the farthest viewer, we apply the standard distance multiplier:

• Distance to Farthest Viewer = Screen Height x (10 to 12 times the element height)

Using the more common 12 times the element height for better visibility in presentations:

• Distance to Farthest Viewer = 54 inches x 12 = 648 inches

This distance refers to the general maximum viewing distance for good eye comfort and readability, ensuring that the farthest viewer can effectively see the content being displayed.
