- An aspect ratio is a value that describes the width and height of a screen or image.
- It is written as two numbers separated by a colon (a ratio).
- The first number shows the image’s width and the second its height.
- For instance, a 16:9 aspect ratio means the image is 16 units wide and 9 units high.
- Aspect ratio is important because it allows the display of proportional images on your screens.
- Proportionality means that the size of the subject you see on your screen is distributed equally between the width and height of your TV frame.
- 16:9 is the standard aspect ratio for high-definition widescreen televisions and most computer monitors.
