Projection formats: history and standards

From the earliest cinematographs to modern inflatable screens, the world of cinema projection has undergone a fascinating evolution. Discover the different image formats, their history and their use around the world.

The origins of cinema: the 1.33 ratio

As early as the 1890s, 35 mm film imposed the 1.33:1 (4/3) format, meaning four units wide for three high; the "Academy format" 1.37:1 was not established until 1932. This format remained the standard for silent cinema for three decades.

The first films projected in theaters were shot in this format, and the cinematic experience was established around this proportion.

The 1950s: the arrival of widescreen cinema

Facing competition from television, Hollywood launched Cinerama (2.59:1) in 1952, followed by CinemaScope (2.55:1, later reduced to 2.35:1) to offer a spectacle that the small screen could not reproduce.

These panoramic formats required special lenses and wider screens. The 1953 CinemaScope revolutionized the industry with its anamorphic lenses.

Modern formats by country

The shift to digital

Since 2010, digital projection has transformed the industry. The DCI (Digital Cinema Initiatives) standards define:

• 2K — 2048x1080 pixels
• 4K — 4096x2160 pixels

These resolutions allow for superior image quality and more flexible distribution.

Impact on inflatable screens

For open-air screenings with inflatable screens, the 16:9 (1.78:1) format remains the most common. It is compatible with the majority of modern content:

• Contemporary films
• TV series
• Streaming content
• Advertising and events

Practical info: For an outdoor cinema inflatable screen, the 16:9 format offers the best compatibility. For classic films in the Academy format, black bars appear on the left and right of the image.

Conclusion

The history of projection formats reflects the evolution of cinema itself. From the 1.33 ratio of early films to contemporary 2.35:1 panoramas, each format tells part of the story of the seventh art.

Whether you are organizing an open-air movie night or choosing a professional screen, understanding these formats allows you to create the optimal experience for your audience.
