If you know the price range you want to spend, you need to decide what size of a TV screen you desire. Most people think the bigger the better, but your budget will determine your selection. In addition to budget, however, the viewing distance from the screen is one of the most important aspects of choosing a television screen. If you sit close to the TV, you won't need a large screen; if you sit farther away, however, you'll need a bigger screen for decent viewing. See the below chart, copied from CNet, for the idea screen sized based on your viewing distance.The below chart is based on HDTVs. The quality of the picture effects the ideal distance from the screen. The sizes are also measured in widescreen TVs, since virtually all high definition televisions are widescreen.



In addition to budget and distance from your TV, you should consider the room and who will use it. If it's a smaller room, a smaller TV will probably suffice. If it's a larger room, meant for a large amount of people, or is the primary TV of your home, a larger screen is almost always better.
