Measure the Size of a TV Screen
1. Measure the screen diagonally from corner to corner to determine the manufacturer's advertised screen size.
2. Measure the width and height of the screen to determine the aspect ratio.
3. Measure the width and height of the TV with the frame to determine if it will fit on your shelf or TV stand.
4. Multiply the diagonal screen size by 1.2 to determine the proper viewing distance from the TV.
