Did The New iPhone Aspect Ratio Just Break Vertical Video?

The new iPhone Duo has two displays, joined by a hinge. The inner display is 7.6 inches and roughly 1.4:1 which is much squarer than the 9:16 portrait format we've spent the last decade optimising for.

Exciting? Headache inducing? Both, probably 🤷‍♀️

While Apple hasn't killed vertical video, it may have just given us a reason to stop treating 9:16 as the answer to every creative question.

If you're making things for screens, here's what the new iPhone aspect ratio could mean.

What is the new iPhone aspect ratio, exactly?

The iPhone Duo has two displays, joined by a hinge. But here's the interesting bit: Apple has deliberately given them the same aspect ratio. The difference is scale.

Cover display: 5.4 inches, a conventional phone-sized portrait display

Inner display: 7.6 inches, with a much squarer, approximately 1.4:1 shape

Inner resolution: 1878 × 2670

Outer resolution: 1398 × 203

It's one composition with two different canvases. Potentially much more interesting for brand and creative teams. Download the comparison chart to the right.

Why the new iPhone aspect ratio is a bigger deal than one more format to export

We've spent well over a decade training audiences, and ourselves, on 9:16. TikTok. Reels. Stories. Shorts. Vertical became the default because that's how people hold their phones so for a lot of social content, it makes perfect sense.

But open the iPhone Duo and suddenly there's considerably more room around your composition. Not a 4:3 screen. Not quite a tablet. Not a conventional phone. Something in between.

This isnt entirely new territory. Samsung has already pushed its Fold range towards a squarer unfolded display, while Google's foldables have gone even squarer. 

Apple isn't inventing the format. But what's different is that Apple is bringing that experience into the iPhone ecosystem and deliberately keeping the same aspect ratio between the cover and inner displays.

Designing for the new iPhone aspect ratio

Here are a few things to consider for future creative briefs…

1. Design for two scales, not two completely different formats

The temptation will be to create a portrait asset for the cover display and another, wider asset for the inner display. But because the two screens share the same aspect ratio, you don't necessarily need to think of them as two unrelated canvases.

Think about how your composition behaves as it expands.

Does the subject remain legible?

Does the headline still work?

Does the extra space reveal something useful, or simply expose a lot of empty background?

The challenge is making the additional canvas earn its keep.

2. Design with the crease, not against it

Apple has put considerable engineering effort into making the fold as unobtrusive as possible. When the phone is open, the intention is for the display to feel like one continuous surface. So don't automatically treat the hinge as a dividing line.

Don't centre a logo or headline directly over it just because that's where the middle of the screen happens to be. Instead, think about the entire open display as one composition. Or, even better, ask whether the hinge can become part of the idea!

3. Design for the moment before the unfold

The cover display isn't a smartwatch or a loading screen. It's a fully usable 5.4-inch phone display, but the fold creates something ordinary smartphones don't have: a before and an after. What could your creative show when the device is closed? What does it reveal when it opens? Could the cover display tease the story? Could a product detail become a wider scene? Could a piece of typography gain meaning when more of the canvas appears?

Instead of treating the cover as the smaller version of the campaign, think about it as the first act.

4. Storyboard for the expanded canvas

A decade of vertical-first thinking means a lot of storyboards now start in portrait before anyone even asks for it. That's not necessarily a bad thing, but it can become a creative reflex.

For the Duo, consider composing specifically for the expanded canvas. Not necessarily "landscape-first", because the device works in both orientations, but space-first.

What can you do when your frame suddenly has more breathing room?

• Wider environmental storytelling.
• More characters.
• More negative space.
• Multiple points of action.
• Typography that can actually breathe.

A visual idea that feels cramped at 9:16 might suddenly make sense!

5. The hinge is a mechanic, not a limitation

This is where things get really interesting. A foldable gives you a storytelling device that a conventional phone doesn't.

Closed ➜ open.

Small ➜ expansive.

Tease ➜ reveal.

One perspective ➜ another.

Imagine a product appearing on the cover screen and the world around it being revealed when the phone opens. Or a headline that completes as the canvas expands, a character moving from the narrow screen into the wider environment, or an interactive experience where the physical act of opening the device becomes part of the interaction.

That's a new creative mechanic which gets us creative folks all fired up!

6. Prototype on the actual device before you scale a campaign

New hardware rarely behaves exactly how you imagined it would from a spec sheet.

• Typography.
• Touch targets.
• Safe areas.
• The hinge.
• Cropping.
• Motion.
• The way people actually hold the device.

All of these things need testing so get hands-on with the hardware where possible. If you can't, prototype at the correct physical dimensions and test the experience before production gets expensive.

The worst possible outcome is spending six weeks making something beautiful and discovering that nobody can comfortably interact with it!

The Actual Opportunity

The lazy response to a new screen is obvious:

Resize 📐

Re-export 📤

Tick the box ✅

Job done. 🤝

But that's not a strategy, and it’s also no fun!

The interesting opportunity is to create something that benefits from the device being able to change size.

• A cover-screen teaser that earns the open.
• A product reveal that only makes sense when the canvas expands.
• An experience that uses the additional space rather than filling it with a bigger version of the same thing.

The Creative Challenge

For years we've been told to think mobile-first. Then vertical-first. Maybe the next step isn't another "first". Maybe it's thinking about how the frame behaves because screens aren't getting simpler. They're folding, stretching, rotating, expanding and changing shape. Our job isn't to make the same idea fit all of them. It's to understand what each screen makes possible.

The iPhone Duo isn't going to replace TikTok, Reels or 9:16 video, but it might remind us of something we've occasionally forgotten in the rush to optimise. The format isn't the idea. It's the canvas, and the best creative teams don't just resize the canvas, they use it intentionally.
