Assuming the same floor space or “footprint,” you can replace your present CRT TV with a 4:3 aspect ratio with a flat-panel TV having a larger screen size. When it comes to viewing distance, with CRT TVs a distance of five to seven times the screen height is considered ideal, whereas about three times the screen height is fine for a HDTV plasma or LCD TV with a clear, sharp picture. So you can enjoy a big-screen TV, like a widescreen 50- or 42-inch model, in a much more compact space than you probably realized.
