Which statement correctly describes screen size measurement?

• A. Measured diagonally in inches
• B. Measured by area in square inches
• C. Measured by total pixel count
• D. Measured by vertical height

Answer: (A)

Screen size is measured diagonally, in inches. This single diagonal distance from one corner to the opposite corner provides a consistent way to describe the overall size of a display, regardless of its width and height. If you looked at area instead, two screens with the same diagonal could have very different viewing areas because aspect ratio changes the shape. Pixel count relates to resolution, not physical size, so it doesn’t tell you how big the screen is in the room. Vertical height varies with aspect ratio and isn’t a universal size measure. So the diagonal-in-inches method is the standard, practical way to describe screen size.
