 ASPECT RATIO Definition
We define ASPECT RATIO |
ASPECT RATIO - The ratio of the width by the height on a monitor or television screen. Most TVs and monitors have a 4x3 aspect ratio--the screens are 4 units wide and 3 units high. A movie screen has an aspect ratio of 16x9 (a bit wider than 5x3), and that's why we have letterboxed movies (when you show a movie in true form on a TV you get black boxes on the top and bottom of the screen). HDTV screens today and some monitors support 16x9 aspect ratios, but most televisions and monitors still retain the 4x3 aspect ratio. |
