What is meant by 'screen size' in relation to monitors?

Screen size in relation to monitors refers to the diagonal measurement from one corner of the screen to the opposite corner. This measurement is standard practice in the industry and provides a clear representation of the overall size of the display.

When consumers evaluate monitors, this diagonal measurement helps them compare different screens regardless of their aspect ratio, which is the ratio of width to height. For example, a 24-inch monitor does not merely describe its height or width, which can differ across different models; instead, it denotes the size of the screen which impacts viewing experience, clarity, and usability.

While height, width, and display area are important specifications, they do not singularly provide the comprehensive measure of screen size that the diagonal measurement does. Therefore, for assessing monitor size adequately, referring to the diagonal measurement is essential.
