About
Aspect Ratios
The term “aspect ratio” simply refers to the ratio of
the picture’s width to its height. Nonetheless there
is some room for confusion, as the original film, the
picture transferred to the disc, and the display itself
each have their own aspect ratio. Most viewers prefer
to see the film in its original aspect ratio, which
preserves the director’s intention for the visual
composition of the film and is made easy with the

Aspect Ratios of Video Displays
Originally video displays were created with a 4:3
aspect ratio, mimicking the original aspect ratio
used in films. These types of displays are less
commonly available today, and are often referred to
as “standard” displays.
Most modern displays now use a 16:9 aspect ratio
and are referred to as “widescreen” displays.
Widescreen displays are highly preferred for
displaying the wide aspect ratio movies that have
been commonly made for the last 40 years.
