Question: how to find the length and width of a tv?
Answer: Measure a TV diagonally, from corner to corner, to get a measurement that manufacturers use. You might think that a 32 inch (81 cm) TV is 32 inches wide, from bottom left to bottom right. Not so. A 32 inch TV is 32 inches (81 cm) from bottom left to top right, or bottom right to top left.
