How it works
The diagonal is the hypotenuse of a right triangle whose sides are the width and height. So each side is the diagonal times its ratio number, divided by the square root of the two ratio numbers squared added together.
Common shapes are 16 by 9 for most TVs and monitors, and 16 by 10 for some laptops.
Worked example
A 27 in screen in a 16 to 9 shape is 23.533 in wide and 13.237 in tall.
Questions
Is the diagonal measured on the glass?
Usually it is measured on the visible screen, not the frame. Check the product listing if you need the exact figure.
Will a screen of this shape fit my space?
Compare the width and height with your space and leave room for the frame and any stand.
What about curved screens?
Curved screens are measured differently. This figure is for flat screens only.
