The height and width of a 55-inch TV can vary slightly depending on the brand and model, but typically a 55-inch TV will have a width of approximately 48-50 inches (122-127 cm) and a height of approximately 28-30 inches (71-76 cm) without the stand. With the stand, the height may increase by a few inches. It's important to check the specific dimensions of the TV you're interested in before purchasing to ensure it will fit in your desired location.
