A 55 inch LED TV typically measures approximately 48.5 inches in width and 28 inches in height without the stand. With the stand, the height may increase to around 30 inches. The depth of the TV can vary from model to model, but it generally ranges from 2 to 4 inches. These dimensions may also differ depending on the brand and specific model of the LED TV. It is essential to consider the TV's dimensions to ensure that it fits properly in the desired space and provides an optimal viewing experience. Additionally, it is important to leave enough space around the TV for ventilation and for any necessary cables and connections.
