Widescreen
Widescreen is often used as a nickname for the 16:9 aspect ratio of television screens. This means that if the television screen was sixteen inches wide it would have to be nine inches tall. Most 20th century television screens were 4:3 which means if it was four inches wide it would have to be three inches tall.  A widescreen could be any size with the same ratio.  For example, a screen could be 32 feet wide and 18 feet tall and still be considered widescreen.
