Applying the same geometric mean technique to 16:9 and 4:3 yields an aspect ratio of around 1.5396:1, sometimes approximated as 14:9 (1.5 5:1), which is likewise used as a compromise between these ratios. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 and 2.35:1, √ 47 / 15≈1.77:1 which is coincidentally close to 16:9. 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 7:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.78:1. Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios.

The popular choices in 1980 were 4:3 (based on TV standard's ratio at the time), 15:9 (the European "flat" 1.6 6:1 ratio), 1.85:1 (the American "flat" ratio) and 2.35:1 (the CinemaScope/ Panavision) ratio for anamorphic widescreen. Powers, a member of the SMPTE Working Group on High-Definition Electronic Production, first proposed the 16:9 (1.7 7:1) aspect ratio in 1984, when nobody was creating 16:9 videos. The calculation considers the extreme rectangles, where m and n are multipliers to maintain their respective aspect ratios and areas.ĭr. DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.40:1 within the 16:9 DVD frame by hard matting or adding black bars within the image itself.ĭerivation of the 16:9 aspect ratioThe main figure shows 4:3, 1.85:1, and 2.35:1 rectangles with the same area A, and 16:9 rectangles that covers (black) or is common to (grey) them. Many digital video cameras have the capability to record in 16:9, and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard.

Japan's Hi-Vision originally started with a 15:9 (1.6 6:1) ratio but converted when the international standards group introduced a wider ratio of 16 to 9. It has replaced the fullscreen 4:3 aspect ratio.ġ6:9 (1.7 7:1) (said as sixteen by nine or sixteen to nine) is the international standard format of HDTV, non-HD digital television and analog widescreen television PALplus.

Once seen as exotic, since 2009, it has become the most common aspect ratio for televisions and computer monitors and is also the international standard format of digital television HDTV Full HD and SD TV. An LCD television set with a 16:9 image ratio.ġ6:9 (1.7 7:1) is a widescreen aspect ratio with a width of 16 units and height of 9.
