Standard NTSC television sets have an aspect ratio of 4:3 (4 units wide by 3 units high). Widescreen television sets have an aspect ratio of 16:9. Many films are produced with even wider ratios. Pictures with aspect ratios different from the display will show dark bars at the top and bottom, or at the sides. See: Widescreen, NTSC.
