16:9 (1.7:1) is an aspect ratio with a width of 16 units and height of 9. It is 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."
When the 16:9 (1.7:1) 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: 4:3 (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 1.7:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.7:1. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 (1.3:1) and 2.35:1, which is coincidentally close to 16:9 (1.7:1). 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 (1.7:1) 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 (1.3:1) and 2.39:1 video is now recorded using a "shoot and protect" technique that keeps the main action within a 16:9 (1.7:1) 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.
Audiences generally see such centrally framed information as distracting. However, audiences of 16:9 ratio scenes can find odd moving elements that are centrally framed. This has similarities to the effect a filming technique called Open matte can have. 4:3 content upconverted to a 16:9 standard is generally referred to as pillar boxed and many high definition television networks have adopted decoratively branded logos to fill the null area.
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:
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”
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).
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, fit quite comfortably onto a 1.7:1 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.
