If the text height is 6 inches, what is the furthest viewer distance for normal vision in BDM viewing conditions?

To determine the furthest viewer distance for normal vision in Business Display and Media (BDM) viewing conditions, one common guideline used is the relationship between text height and viewing distance. A typical recommendation suggests that the maximum distance for comfortable viewing of text is approximately 40 times the height of the text.

In this scenario, the text height is given as 6 inches. By applying the guideline:

Maximum Viewing Distance = Text Height x 40

Maximum Viewing Distance = 6 inches x 40

Maximum Viewing Distance = 240 inches

This distance aligns with the option indicating 240 inches, which means that at this distance, a person with normal vision would still be able to read the text comfortably. Therefore, the answer reflects the proper calculation based on the standard measurement for text viewing distance in these specific conditions.
