Apple’s iPhone Duo is arriving with a display proportion that has prompted an unusually specific bit of cinema-format chatter: both its inner and outer displays use a 1:1.4 aspect ratio. That makes the screens notably squarer than the wide rectangles most people associate with phones, televisions, and modern blockbuster presentation. It also places the Duo unexpectedly close to one of the most recognizable tall image formats in movie history: IMAX’s classic 1.43:1 full-frame presentation.
IMAX has acknowledged the resemblance with exactly the mix of amusement and self-preservation one might expect from a company built around giant screens and theatrical scale. Replying on X to speculation that the iPhone Duo could encourage more content in a roughly 1.4:1 frame, the company’s official account expressed support for the coincidence before quickly making its position clear: movies, in IMAX’s view, still belong somewhere much larger than a handset.
“Love this for them,” the account wrote, before adding: “Still not watching movies on a phone...”
It is a small exchange, but it puts a spotlight on a genuine visual overlap. The iPhone Duo is not an IMAX screen, and its 1:1.4 measurement is not identical to 1.43:1. Still, the two are close enough that the comparison immediately makes sense. For film fans, gadget enthusiasts, and anyone who has ever noticed black bars shifting from one movie to the next, it is a reminder that aspect ratio is more than a specification-sheet number. It changes the shape of the image, the kind of composition creators can use, and the feeling of viewing something on a small or enormous display.
Why 1:1.4 looks so different
An aspect ratio describes the relationship between an image’s width and height. A 1:1 display is a perfect square. A 1:1.4 image is taller than it is wide, while still remaining relatively close to square. That is a substantial departure from the broad horizontal screens familiar from contemporary TVs, monitors, and much mobile video.
The iPhone Duo’s 1:1.4 format therefore gives it a distinctly boxier canvas in either configuration. Rather than treating the exterior panel as a conventional narrow phone screen and the interior as a dramatically wide miniature tablet, Apple has placed both displays in the same general visual family. The result is a shape that naturally invites comparisons to taller movie imagery, even if the device’s purpose extends far beyond film playback.
That proximity is especially striking because IMAX’s 1.43:1 format has a clear historical origin. The classic full-frame ratio comes from the geometry of the company’s original 15-perforation, 70mm film system. In simple terms, that system produced an image shape with considerably more vertical presence than the wide formats that dominate much commercial cinema. When footage fills that tall frame in a properly equipped theater, the effect is designed to emphasize scale and immersion.
A pocketable screen obviously cannot reproduce the physical impact of that theater environment. The image may share a broadly similar outline, but dimensions, viewing distance, sound, projection, and venue are all different parts of the experience. That gap is the joke—and the point—behind IMAX’s response. The company can appreciate a familiar silhouette turning up in a new piece of consumer hardware without confusing a 1:1.4 phone display for its own large-format proposition.
Near-matching numbers do not create a new IMAX venue
The conversation is likely to tempt some dramatic shorthand: an “IMAX phone,” perhaps, or a suggestion that a near-1.43 device instantly makes every tall-format film a better fit. It is worth resisting that leap. An aspect ratio alone does not turn one screen into another category of viewing experience.
What it does provide is a potentially interesting canvas. A 1:1.4 display can show a tall image with less unused space than a much wider panel would require. Conversely, conventional wide video will not naturally fill the screen without some compromise, such as blank areas above and below the picture, cropping, or expansion that changes the original framing. Those are ordinary consequences of fitting differently shaped images to differently shaped screens, not evidence that one ratio is universally superior.
The useful distinction is between compatibility of shape and equivalence of presentation. The Duo’s ratio is compatible, in a broad geometric sense, with the classic IMAX full-frame look. It is not equivalent to the conditions that made that format famous. A tall image on a phone remains a tall image on a phone.
That does not make the ratio meaningless. Smartphones are personal screens where people read, browse, message, photograph, play games, and watch clips as well as movies. A more square-like display changes the balance among those tasks. In cinematic terms, it may make vertically generous imagery look less alien than it would on an ultra-wide surface. In practical terms, it may also affect how apps arrange information and how developers think about layouts. The IMAX comparison is memorable because it gives consumers a familiar cultural reference point, not because the device is trying to replace a theater.
A format conversation with gaming implications
Aspect ratios matter in games too, although the iPhone Duo conversation should not be mistaken for a promise of any particular gaming support or visual mode. No game-specific software plans are established by IMAX’s social post. Still, the hardware shape raises familiar questions for developers and players: how will interface elements be arranged, how will games handle the taller visible space, and whether a near-square canvas will feel especially natural for certain genres?
Games have a long history of adapting to the screens available to them. Arcade cabinets, handhelds, CRT televisions, wide monitors, dual-screen devices, and phones have all influenced interface design and composition. A taller panel can leave room for maps, inventories, touch controls, chat, cards, or status displays without demanding that every game itself be presented in a tall cinematic format. It can also create design challenges when a title was made around a different default shape.
For enthusiasts who enjoy the technical and archival side of display formats, the coincidence is simply fun. A numerical neighborhood normally reserved for discussions of film stock and specialty auditoriums has suddenly shown up in a flagship mobile-device conversation. It is the kind of detail that makes screen geometry briefly feel like pop culture.
Apple’s wider hardware ecosystem has been part of gaming and media discussions before, including the company’s laptop range; for a separate look at current Apple-related hardware deals, see this roundup of M5 MacBook Pro, Studio Display, and AirTag 2 discounts. The iPhone Duo angle, though, is unusually centered on the literal frame around whatever users choose to watch or play.
Could more 1.4-ish content follow?
The question that drew IMAX’s reply was whether the Duo might lead to more 1.4:1 material. For now, that remains speculation. The device’s display ratio is a notable creative constraint and opportunity, but it is only one factor among many in deciding how video, games, and applications are made. Creators routinely target audiences using many screen types, and media is commonly designed to adapt across devices rather than exclusively serving one display shape.
There is also an important precision point in the original question: 1:14.1 appears to have been written there, while the surrounding discussion concerns the Duo’s 1:1.4 display ratio and IMAX’s 1.43:1 ratio. The relevant comparison is plainly the latter pair of near-square, tall formats—not a 1:14.1 image, which would describe something radically different.
The more plausible immediate outcome is attention rather than a sudden industry-wide shift. The Duo gives people a new mainstream reference for a shape that is closer to historic full-frame IMAX than today’s usual handheld-screen assumptions. That may encourage more talk about framing, but it does not by itself establish a new production standard or guarantee that movies will be mastered around the device.
Dates to know for the iPhone Duo
For people interested in the hardware beyond the format discussion, iPhone Duo pre-orders are scheduled to open on October 16. The launch follows on October 23. Those dates frame the current debate neatly: before the device has reached buyers, its dimensions have already become part of a broader conversation about how screens shape the media placed inside them.
IMAX’s answer is also a tidy statement of brand identity. The company is happy to see a distant cousin of its classic 1.43:1 frame appear on Apple’s new device. But the tall rectangle is only one ingredient of the IMAX idea. A phone may carry a near-match in proportions in a pocket, while IMAX remains firmly committed to the proposition that a movie should be watched on a screen that makes a pocket look very, very small.
