ELI5: Why are monitors wider, and not taller?

And TVs for that matter. Also, why don't they have the same height and width?

Human vision is much wider than it is tall. You can see things far off to the side without moving your eyes much. So TV and movie screens are wide. And computer screens are wide in case you want to watch a TV show or a movie on them. Some computer screens can rotate so they are tall and narrow.
