Diagonal Relationship: Because the aspect ratio for video is 4:3, the diagonal produced from those numbers turns out to form a perfect integer relationship: 3 - 4 - 5.
For instance: How large is a 100 inch (diagonal) video screen?
Dividing 100 by 5 equals 20. This multiplied by 3 equals the height of the screen = 60 inch.
Multiply the same 20 by 4 and we get the screen width = 80 inch.
The viewable size of the monitor or video screen is measured from one corner of the screen to the opposite corner of the screen in inches. Monitor sizes are normally advertised with a number, which can vary significantly.
The following table shows the monitor's advertised diagonal screen size along with the approximate diagonal measure of the actual active viewing area for the most common display sizes.
