Aspect Ratio in Film From Past to Present

The Evolution of the Frame

The history of the frame began somewhat arbitrarily in 1888 when Thomas Edison’s engineer, William Dixon, split 70mm roll film in half to create 35mm film.

Settling on an image height of four perforations, the 1.33:1 aspect ratio was born.

This format, which later shifted slightly to the 1.375:1 Academy ratio to incorporate optical sound tracks, dominated cinema for over 60 years.

By the 1950s, dropping theater revenues forced Hollywood to innovate, leading to the birth of widescreen cinema to entice audiences back.

Initial solutions like Cinerama utilized three synchronized cameras and projectors to stitch a massive image together.

However, a more practical, mainstream answer emerged with 20th Century Fox’s CinemaScope.

This technology adapted French tank-viewing optics to use anamorphic lenses, compressing a wider image onto standard film that was later stretched back during projection, yielding a panoramic aspect ratio usually cropped to 2.35:1 or 2.4:1.

Seeking an alternative to licensing Fox’s technology, Paramount developed VistaVision in 1954, running 35mm film horizontally.

VistaVision popularized the 1.85:1 ratio, which was chosen based on scientific consensus that it closely matched the natural field of human vision.

Compositional Impact and Storytelling Mechanics

Different aspect ratios profoundly alter how filmmakers approach staging, character blocking, and set design:

• The Academy Ratio (1.33:1 / 1.375:1): Highly effective for close-ups and single character frames because the human face comfortably fills the square space without environmental distractions. While great for vertical, deep-set staging, it struggles with horizontal groups and expansive landscapes.
• Widescreen / Scope (2.35:1 / 2.4:1): Naturally panoramic, this frame allows the audience’s eyes to roam across multiple points of interest. Close-ups can leave awkward, empty spaces, forcing editors to “dirty the frame” using over-the-shoulder shots or “aperture framing” (placing actors inside doorways or windows) to manage the vast width. It excels at horizontal layout staging (“clothesline staging”) and wide environmental storytelling.
• The Middle Ground (1.85:1 & 1.78:1 / 16:9): These balanced formats comfortably manage both horizontal layout and vertical depth staging. They provide enough space to showcase the environment without requiring aggressive framing techniques to control excessive screen width.

Modern Adaptations and Creative Application

In recent decades, technical demands have yielded new formats.

The digital era established 1.78:1 (16:9) as the standard for high-definition television, finding a mathematical average between old TV broadcasts and widescreen films.

Additionally, streaming services like Netflix and Amazon have driven a resurgence in the 2.0:1 ratio, offering an immersive widescreen aesthetic without wasting screen space via aggressive letterboxing on modern TVs and portable devices.

Conversely, smartphones have popularized vertical formats, which accommodate human anatomy but severely restrict environmental framing.

Today, professional filmmakers choose aspect ratios based on narrative context rather than technical limitations.

For example, Wes Anderson shifted between three distinct ratios in The Grand Budapest Hotel to distinguish different historical eras. Similarly, the film Ida utilized the vintage 1.375:1 ratio to evoke a specific era and intentionally generate abundant headroom, symbolizing the characters’ thoughts toward heaven.

Conversely, La La Land adopted an expansive CinemaScope format to pay homage to classic golden-era musicals.

Ultimately, the aspect ratio is a psychological tool; a frame is most successful when it remains invisible to the audience, allowing them to look through the borders rather than at them.
