What would be the farthest viewer distance when the element height is 1.5 inches?

In audiovisual design, the farthest viewer distance is often calculated based on the height of the screen or display elements. A common guideline used in this context is that the viewer distance should be approximately 200 times the height of the display for comfortable viewing, particularly for large displays.

Given an element height of 1.5 inches, the farthest viewer distance can be calculated as follows:

1.5 inches * 200 = 300 inches.

This calculation reflects the idea that a larger viewer distance helps ensure that the entire display can be seen comfortably and without straining, as smaller text and details may become difficult to discern at closer distances. This leads to the conclusion that a viewer should ideally be positioned no more than 300 inches away from a display that is 1.5 inches tall to achieve optimal viewing comfort and visual clarity.

The distances represented by the other options would not provide the same level of comfort or usability based on this guideline, hence they are not suitable for this particular height.
