Typically, a 70-inch LED television is 61 inches tall and 34.25 inches broad. Most high-definition televisions have a 16:9 aspect ratio; the diagonal distance between two opposite corners of the TV is the advertised size.
The diagonal distance between two TV corners is always greater than the TV’s height or breadth.
If both televisions have the same aspect ratio, a television that is twice as large as a smaller television when measured diagonally has more than four times the total viewing area. A 70-inch television is approximately twice the size of a 50-inch television.
