16:9

Widescreen in square units

16:9 (or widescreen) is the ratio with the width of 16 units by the height of 9 units.

In the early 21st century, widescreen became the conventional video aspect ratio for HDTV, SDTV, and computer monitors and it is often used in smartphone screens.

  Derivation of the 16:9 aspect ratioThe main figure shows 4:3 and 2.40:1 rectangles with the same area A, and 16:9 rectangles that covers (black) or is common to (grey) them. The calculation considers the extreme rectangles, where m and n are multipliers to maintain their respective aspect ratios and areas.
