An LCD television set with a 16:9 image ratio.

16:9 (1.77:1) (16:9 = 4²:3²) is an aspect ratio with a width of 16 units and height of 9. Since 2009, it has become the most common aspect ratio for sold televisions and computer monitors and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen television (EDTV) PALplus.

Generally 16:9 is pronounced "Sixteen-Nine", "Sixteen-by-Nine," or "Sixteen-to-Nine."

History

File:Dr. Kerns Powers, SMPTE derivation of 16-9 aspect ratio.svg

Equal area comparison of the aspect ratios used by Dr. Powers to derive the SMPTE 16:9 standard. TV 4:3/1.33 in red, 5:3/1.66 in orange, 16:9/1.77 in blue, 1.85 in yellow, Panavision 11:5/2.2 in mauve and CinemaScope/2.35 in purple.

When the 16:9 (1.77:1) aspect ratio was proposed by Kerns H. Powers, a member of the SMPTE Working Group On High-Definition Electronic Production, nobody was creating 16:9 videos. The popular choices in 1980 were: 1.33:1 (based on television standard's ratio at the time), 1.66:1 (the European "flat" ratio), 1.85:1 (the American "flat" ratio), 2.20:1 (the ratio of 70 mm films and Panavision) and 2.35:1 (the CinemaScope ratio for anamorphic widescreen films).

Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios. When overlapped with their center points aligned, he found that all of those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 1.77:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.77:1. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 (1.33:1) and 2.35:1, which is coincidentally close to 16:9 (1.77:1). Applying the same geometric mean technique to 16:9 and 4:3 yields the 14:9 aspect ratio, which is likewise used as a compromise between these ratios.

While 16:9 (1.77:1) was initially selected as a compromise format, the subsequent popularity of HDTV broadcast has solidified 16:9 as perhaps the most important video aspect ratio in use. Most 4:3 (1.33:1) and 2.39:1 video is now recorded using a "shoot and protect" technique that keeps the main action within a 16:9 (1.77:1) inner rectangle to facilitate HD broadcast. Conversely it is quite common to use a technique known as center-cutting, to approach the challenge of presenting material shot (typically 16:9) to both a HD and legacy 4:3 audience simultaneously without having to compromise image size for either audience. Content creators frame critical content or graphics to fit within the 1.33 raster space. This has similarities to a filming technique called Open matte.

After the original 16:9 Action Plan of the early 1990s, the European Union has instituted the 16:9 Action Plan, just to accelerate the development of the advanced television services in 16:9 aspect ratio, both in PAL and also in HDTV. The Community fund for the 16:9 Action Plan amounted to €228 million.

In 2008 the computer industry started to use 16:9 as standard aspect ratio for monitors and laptops. According to a report by displaysearch the reasons for this were/are:

• Innovative product concepts drives a new product cycle and stimulating the growth of the notebook PC and LCD monitor market.
• 16:9 provides better economic cut (panelization) in existing TFT LCD fabs.
• 16:9 products provide higher resolution and wider aspect ratio.
• The widespread adoption of High Definition in the consumer entertainment sector will help end users readily adopt the new products with the wider aspect ratio.
• The 16:9 panels provide an opportunity for PC brands to further diversify their products.

In 2011 Bennie Budler, product manager of IT products at Samsung South Africa, confirmed that monitors capable of 1920x1200 resolutions aren't being manufactured anymore. “It is all about reducing manufacturing costs. The new 16:9 aspect ratio panels are more cost effective to manufacture locally than the previous 16:10 panels”. Since computer displays are advertised by their diagonal measure, for monitors with the same display area, a wide screen monitor will have a larger diagonal measure, thus sounding more impressive. Within limits, the amount of information that can be displayed, and the cost of the monitor depend more on area than on diagonal measure.

In March 2011 the 16:9 resolution 1920x1080 became the most common used resolution among Steam's users. The earlier most common resolution was 1680x1050 (16:10).

Properties

16:9 is the only widescreen aspect ratio natively supported by the DVD format. Anamorphic DVD transfers store the information as 5:4 (PAL) or 6:4 (NTSC), which is set to expand to either 16:9 or 4:3, which the television or video player handles. For instance, a PAL DVD with a full frame image may contain a video resolution of 720x576, but a video player will stretch this to 1024x576 with a 16:9 flag in order to maintain the correct aspect ratio.

DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.39:1 within the 16:9 DVD frame by hard matting or adding black bars within the image itself. Some films which were made in a 1.85:1 aspect ratio, such as the U.S.-Italian co-production Man of La Mancha and Kenneth Branagh's Much Ado About Nothing, fit quite comfortably onto a 1.77:1 HDTV screen and have been issued anamorphically enhanced on DVD without the black bars. Many digital video cameras have the capability to record in 16:9.

Super 16 mm film is frequently used for television production due to its lower cost, lack of need for soundtrack space on the film itself, and aspect ratio similar to 16:9.

Common resolutions

Common resolutions for 16:9 are 640x360, 854x480, 960x540, 1024×576, 1280×720, 1366×768, 1600×900, 1920×1080, 2048x1152, 2560×1440, 3840×2160 and 4096x2304.

1080p (Full HD) is 1920×1080, while 720p (HD) is 1280×720.

In Europe

In Europe, 16:9 is being adopted as the standard broadcast format for digital and HDTV. Some countries have even adopted the format for analog television by means of the PALplus standard.

United Kingdom	In 1997, BBC, ITV and Channel 4 began producing 16:9 idents and switched some television shows to 16:9. In 1998, with the introduction of digital television, digital versions of BBC One, BBC Two, ITV 1 and Channel 4 were created. An On Digital set top box or a subscription to Sky Digital was required to view the digital versions. On 1 July 2000, "C-Day", most of the UK broadcast industry began requiring commercials to be delivered in 16:9 full-height format (with a 14:9 safe area for those channels still broadcasting in 4:3). ITV and C4 upgraded their continuity suites to be 16:9 capable at the same time, allowing idents to be broadcast in widescreen format on digital. In 2001, the UK's fourth broadcaster Channel 5 switched to 16:9. In 2002, On Digital became defunct and free-to-air digital television services began to operate under the name of Freeview. In 2003, Sky branded channels were re-branded which included the switch to 16:9. In 2006, BBC HD began broadcasting in 1080i which became the standard for all HD channels. Similar to the switch to Digital in 1998, viewers required an additional set-top-box which was HD capable, one that could be provided from either Sky or Virgin Media. In 2007, Channel 4 HD was launched on Sky. It was later added to Virgin Media in 2009 and then to Freeview HD in 2011. In 2008, ITV 1 HD was launched on Sky and was later added to Virgin Media and Freeview HD in 2010. In 2009, Freeview HD launched allowing viewers to watch BBC HD and ITV 1 HD without a subscription to either Sky or Virgin Media, a Freeview HD set-top box was required. In 2010, Channel 5 HD and BBC One HD were launched on Sky and Virgin Media. BBC One HD was later added to Freeview HD in 2011. As of 2012; All Freeview channels broadcast in 16:9 Almost all cable/satellite channels broadcast in 16:9 with the rest expected to switch by the end of 2012.
