Current technologies allow for flat panel screens ranging from 22-60 inches and have a thin profile that allows for optimal placement in any size room. Size isn't everything when it comes to tv's, the quality of the picture which is decided by peoperties like resolution and contrast play an important role in viewing pleasure.
Choosing between plasma and lcd is also a big decision. Plasma's are cheaper, particularly when it comes to very large screens, they also have deeper blacks. While lcd tv's have a higher resolution and consume less power.
