IMAX blockbusters display at a 1.90:1 aspect ratio in digital projection systems, which is wider than the standard theatrical 1.85:1 format and delivers approximately 26% more image area to the viewer.
This expanded frame was introduced with digital IMAX technology in 2008 to maximize the immersive experience on premium theater screens, allowing filmmakers to compose shots that take full advantage of larger auditoriums.
When you watch Christopher Nolan’s upcoming film “The Odyssey” or “Dune: Part Three” in IMAX, you’re seeing an image that fills more of your visual field than the same film would on a standard screen—the sides extend further, immersing you more completely in the filmmaking.
This article examines why IMAX aspect ratio matters for blockbusters, how it differs from standard cinema, what the technical specifications are, and which major 2026 films are leveraging this format to reshape the theatrical experience.

What Exactly Is IMAX Aspect Ratio and How Does It Work?
The imax aspect ratio of 1.90:1 refers to the width-to-height relationship of the image projected onto the screen. To visualize this: for every 1.90 units wide, the image is 1 unit tall.
When compared to standard theatrical format at 1.85:1, IMAX adds extra width without changing the height, resulting in that noticeable expansion of the horizontal frame you see in premium auditoriums.
This slight widening may seem minor mathematically, but it translates to a significantly larger total image area that envelops more of the viewer’s peripheral vision. Digital IMAX projection achieves this aspect ratio using dual 2K projectors, each displaying half of the image with a half-pixel offset to create a perceived resolution of approximately 2.9K.
This technical approach allows theaters to deploy IMAX technology more cost-effectively than maintaining the older 70mm film projection systems, which is why digital IMAX has become the standard for modern blockbuster releases.
When “Toy Story 5” releases on June 19, 2026, it will display in IMAX auditoriums using this same dual-projector system, filling screens with more animated detail than standard theaters can show.
The Evolution of IMAX Aspect Ratios—From Documentaries to Blockbusters
The current 1.90:1 digital standard represents a significant evolution from the original IMAX format, which used a nearly square 1.43:1 aspect ratio. That original format, still available only in select specialty locations, was developed primarily for documentaries and educational films shot on massive 70mm film stock run horizontally.
The 1.43:1 ratio created an almost square image that worked well for nature documentaries and museum exhibitions, but proved less suitable for narrative storytelling when IMAX expanded into feature films.
Digital IMAX’s introduction in 2008 marked a turning point. The industry recognized that a wider 1.90:1 ratio would better suit Hollywood narratives while still providing the immersive premium experience that justifies premium ticket prices.
Even more recently, the IMAX with Laser system launched in December 2014 with dual 4K laser projectors, further enhancing image quality within that same 1.90:1 aspect ratio.
However, if you’re watching an older IMAX documentary or a specialized educational feature, you might encounter the original 1.43:1 format—and the experience will feel notably different, with less horizontal expansion and a more compact frame.
Why Major Blockbusters Are Being Shot for IMAX
filmmakers increasingly design blockbusters specifically for IMAX projection because the wider 1.90:1 aspect ratio allows them to compose shots that fill more of the viewer’s field of vision, creating immersion impossible on standard screens.
A landscape battle scene in “Dune: Part Three,” shot directly on IMAX film cameras, can extend dramatically across the entire field of view without the black letterbox bars that appear in standard format. This compositional advantage isn’t just visual padding—it’s a creative tool that changes how action, emotion, and spectacle are framed.
The commitment is substantial enough that Christopher Nolan has chosen to shoot “The Odyssey” (2026) entirely with IMAX film cameras, making it the first feature film ever shot completely in that format.
This decision reflects how seriously major filmmakers now treat the IMAX experience as a distinct creative medium rather than just an upscaling of standard content.
For the viewer, this means that watching “The Odyssey” in IMAX will present scenes composed and lit specifically for that wider frame, rather than footage simply enlarged to fill the space.
Technical Specifications and Projection Mechanics Behind IMAX
Understanding how IMAX aspect ratio actually works in theaters requires knowing the mechanics of digital projection. The maximum aspect ratio for IMAX Digital distribution is capped at 1.90:1, which utilizes the full screen image space without requiring theaters to adjust their screen dimensions.
This is a crucial detail: standard 1.85:1 content doesn’t need to be reformatted when released in IMAX—it’s simply displayed with slight pillarboxing (black bars on the sides), while true IMAX content fills the entire 1.90:1 frame.
When you watch Superman (2025) in IMAX, for instance, the film played at its standard 1.85:1 aspect ratio in conventional theaters, but was slightly cropped to fit the 1.90:1 IMAX screen in premium auditoriums.
This slight vertical cropping is generally imperceptible to viewers because the extra width of the IMAX frame absorbs the horizontal composition without losing critical image information.
The dual 2K projector system with half-pixel offset creates a seamless merged image that compensates for the two separate light sources, delivering a unified cinematic experience rather than a visible split down the center.
Notable 2026 Blockbusters Leveraging IMAX Aspect Ratio
The 2026 theatrical calendar has confirmed at least 12 films specifically filmed for IMAX release, signaling that studios view the format as essential for major tentpole productions.
Beyond “The Odyssey,” “Dune: Part Three,” and “Toy Story 5,” Steven Spielberg’s “Disclosure Day” (June 12, 2026) is scheduled for IMAX release, representing a continued commitment from prestige directors to compose blockbusters for premium screens.
This concentration of high-profile IMAX releases in a single year demonstrates how standard the format has become for franchise films and event cinema.
The decision to shoot for IMAX rather than simply upscaling standard footage reflects the format’s value to both filmmakers and audiences. When a director like Nolan or a franchise like “Dune” commits to IMAX cameras from the beginning of production, every shot is framed with the 1.90:1 ratio in mind.
The difference is tangible: an action sequence designed for IMAX extends further into your peripheral vision, while a dramatic close-up in standard format may look cramped by comparison in the wider IMAX frame if not composed carefully.
IMAX Versus Standard Theatrical Aspect Ratio—The Viewing Experience Difference
Comparing the theatrical experience between standard 1.85:1 and IMAX 1.90:1 reveals why the 26% additional image area matters beyond mere technical specifications. In a standard multiplex auditorium, that extra width at the edges of a 35-foot screen represents lost potential for immersion—black space that could have been filled with compositional detail.
In a dedicated IMAX theater, especially larger dedicated IMAX auditoriums with screens that can reach 80+ feet wide, that same expansion becomes transformative, wrapping the image nearly around your field of vision.
The limitation worth noting: IMAX’s benefit depends heavily on theater size. In a smaller IMAX conversion theater retrofitted with dual 2K projectors, the advantage over standard format may be modest. In a full-scale IMAX theater with original 70mm capability or a large-format laser setup, the immersive impact is undeniable.
If you’re comparing how “Toy Story 5” looks in a regional IMAX venue versus a multiplexed standard theater, the difference will be apparent; if you’re comparing it in a mall IMAX versus a standard auditorium of equal size, the advantage is more subtle but still present in the expanded frame width.
The Future of IMAX in Cinema and What Christopher Nolan’s Odyssey Represents
Christopher Nolan’s choice to shoot “The Odyssey” entirely on IMAX film cameras signals a significant shift: the format is no longer an afterthought or a higher resolution option for existing footage, but a primary compositional medium that shapes filmmaking from day one.
This approach mirrors how directors like Denis Villeneuve treat “Dune: Part Three”—not as a compromise between standard and premium formats, but as a film designed first for the largest possible screens with the 1.90:1 aspect ratio as a fundamental creative decision.
The continued expansion of films “filmed for IMAX” in 2026 and beyond suggests that major studios and directors see the premium 1.90:1 format as essential for event cinema. As 4K laser projection technology becomes more widespread and costs decline, the gap between IMAX and standard projection widens in favor of premium formats.
For audiences, this means more blockbusters will be optimally experienced in IMAX auditoriums, with cinematography and visual effects composed specifically for that wider frame.
Conclusion
IMAX aspect ratio at 1.90:1 represents the current standard for premium theatrical presentation, expanding the image width beyond standard 1.85:1 cinema to deliver more immersive framing for major blockbusters.
The format has evolved from the original documentary-focused 1.43:1 ratio through digital IMAX’s introduction in 2008 to the advanced laser projection systems in use today, with filmmakers like Christopher Nolan now treating it as a primary compositional medium rather than an optional upscaling technology.
If you want to experience blockbusters as their filmmakers intended in 2026, seeking out IMAX presentations of “The Odyssey,” “Dune: Part Three,” “Toy Story 5,” and other films shot for the format ensures you’re seeing compositions designed specifically for that wider 1.90:1 frame.
The difference in immersion and visual impact justifies the premium ticket price, particularly in larger dedicated IMAX auditoriums where the expanded aspect ratio can fully envelope your viewing experience.
