A television with the 16:9 image ratio
16:9 or sixteen-nine is an aspect ratio with a width of 16 units and height of 9 units. Once seen as an exotic aspect ratio, since 1999, it has become the most common aspect ratio for televisions and computer monitors, and is also the standard aspect ratio for the UHD, 4K and 8K formats. 16:9 is the widescreen standard format and Wide-aspect Clear-vision. Japan's Hi-Vision originally started with a 15:9 ratio but converted when the international standards group introduced the wider ratio 16:9. Many digital video cameras have the capability to record in 16:9. It is the only aspect ratio natively supported by Blu-ray Disc, but Blu-ray producers can also choose to show even a wider ratio such as 2.40:1 within the 16:9 frame adding Letterbox black bars within the image itself.
