<bot>: Measure a TV
1. Measure your screen diagonally from corner to corner to find the manufacturer's advertised size.
2. Measure the height and width of the TV (including the frame) to make sure it will fit on your stand or cabinet.
3. Measure how thick your TV is to find out if there is enough room on your shelf.
4. Allow a few inches on all sides or your TV for proper ventilation.
