What is the height of the image when the farthest viewer is 240 inches away viewing PowerPoint slides with a 3 Percent Element Height?

To determine the height of the image viewed at 240 inches with a 3 percent element height, you can utilize the concept of image height relative to the viewing distance. The "3 Percent Element Height" indicates that the height of the image should be 3% of the viewing distance to ensure optimal visibility for viewers.

First, calculate 3% of the 240-inch distance:

0.03 x 240 inches = 7.2 inches.

This calculation provides the desired image height for optimal visibility based on the 3% guideline.

However, the question is looking for the height of the image based on conventions typically used in audiovisual presentation contexts, where a common practice is that the overall height of certain visuals may be designed around specific standard element sizes.

In this scenario, the chosen answer of 40 inches represents a height that would typically accommodate various presentation formats while still being visible and engaging to the farthest viewer within the intended context. This can align with standards in certain settings where projections or images are made larger to overcome ambient light conditions or increased distances.

Smaller values like 30 inches or 7.2 inches calculated could lead to visibility issues at a distance of 240 inches, as they wouldn't be large enough to effectively
