The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, in the format width:height. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography.
In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones. [32] In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels. [33] In December 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9 ...
The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass-market computer monitor, laptop, and entertainment products displays. On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square ...
Vertical video has historically been shunned by professional video creators because it does not fit the aspect ratio of established moving image forms, such as film and television, as well as newer web-based video players such as YouTube, meaning that black spaces appeared on either side of the image.
Widescreen images are displayed within a set of aspect ratios (relationship of image width to height) used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1). For TV, the original screen ratio for broadcasts was in 4:3 (1.33:1).

The most common are noted below. High-definition signals require a high-definition television or computer monitor in order to be viewed. High-definition video has an aspect ratio of 16:9 (1.78:1). The aspect ratio of regular widescreen film shot today is typically 1.85:1 or 2.39:1 (sometimes traditionally quoted at 2.35:1).
This aspect ratio was chosen as the geometric mean between 4:3 and 2.35:1, an average of the various aspect ratios used in film. [3] While 16:9 is well-suited for modern HDTV broadcasts , older 4:3 video has to be either padded with bars on the left and right side (pillarboxed), cropped or stretched, while movies shot with wider aspect ratios ...
