There’s a standard for paper sizes called the ISO 216 international standard, aka A-series paper sizes. You may be familiar with it outside of the American 8.5”x11” letter size. The simplicity, for example, where an A3 sheet is exactly twice the area of A4. One A3 sheet folded in half becomes two A4 sheets. This is intentional: when you fold or divide an A-series sheet exactly in half, the resulting sheets have the same proportions as the prior. The aspect ratio is preserved across all A-series paper sizes.
The iPhone Duo is designed with this in mind. The aspect ratio any way you view it, folded or open, is preserved. Apple design knows a thing or two.
- incognition 24d agoI mean, I wouldn't hate it if they got into cars
- butlike 24d agoAn Apple Miata is the dream. Take the design team from the MX-5 NA days and marry it to Apple's design team. Both are exemplar in engineering and the result has me drooling as I day dream here.
- Hatrix 24d agoI imagine it would be held together with glue and tiny screws.
- derac 24d agoApple design is the polar opposite of the MX-5. The MX-5 is a masterpiece of mechanical design and function. Apple makes minimalist purely electronic fashion gadgets that are highly form over function and remove user agency.
- kube-system 24d agoThe Miata is good at one thing which is being fun. It’s not good at being a car. Apple’s devices meet most people’s functional needs very well.
- binoct 24d agoWhat does it mean to not be good at being a car? It’s a terrific car if you want a great handling convertible at a low price point. As you said, it’s fun. It’s not good at moving a lot of people or things, or going really fast, or lasting for 500k miles, or being as cheap as possible. Other cars are good at some of those things, but what is the Miata missing that is otherwise required to be a ‘good’ car?

- numpad0 24d agoThere's already Ferrari Luce
- hn993302 23d agoI'm very glad those Apple Car rumors didn't materialize
- LtWorf 23d agoThen you'd need special apple fuel, special apple wipers fluid, special apple tyres…
- tester756 24d agoBut what's the point?
- estearum 24d agoAspect ratios are very important for UI design.
- fwip 24d agoMoreover, app developers for iOS have to support fewer aspect ratios than developers of Android apps. In theory, this allows for more attention to be given to the UI design for each aspect ratio - rather than having to use a spring-style stretch layout. If I were to guess, this does look like a new ratio to support, but at least it's just 1 instead of 2.
- tester756 24d agoBut why paper's ratio is important?
- Fuzzwah 24d agoOne reason is making it easy to scale things up or down for printing on standard sizes of paper.
- benbayard 24d agoIt's mathematically the only aspect ratio where this holds and thus you can resize in half and nothing has to move around.
- abdullahkhalids 24d agoHe is explaining that if you design an app that displays as desired on the outer display (in portrait mode). Then if you display that app to the inner display (also in portrait mode), it will show up exactly the same, just with everything twice as large. This obviously makes life easier for both users and developers.

- kristianp 24d agoThat's not far off the 4:3 of the Samsung Z fold 8. Around 4.24:3.
- mcapodici 24d agoI always forget the US doesn't use A4 etc. (or do you?)
- ajmurmann 24d agoNo, "letter" is the standard
- ZeWaka 24d agoOr "legal".
- stronglikedan 24d agolegal is a standard, but not the standard. letter is the standard
- actionfromafar 24d agoAnd for writing a letter, ed is the standard editor.
- SllX 24d agoLike as a standard? No. But I can go to a stationery shop and buy an A4 notebook.
- Modified3019 24d agoWe (normal citizens, businesses, government) mostly use “Letter” size https://en.wikipedia.org/wiki/Letter_(paper_size) https://en.wikipedia.org/wiki/Letter_(paper_size) which is slightly shorter than A4 Apparently the reagan admin is responsible for making this our official government document size, and no one knows exactly why this size was chosen.
- 13hours 24d agoLike most of your standards. No-one knows why, but it's obviously advantageous to defend it religiously as "better than everyone else"
- jeswin 24d agoIt was useful for paper because it helped save time in cutting, folding, printing etc. None of that matters for a phone. This is such a non issue given that iOS developers already have so many resolutions to test.
- gessha 24d agoOur world is full of artifacts from a previous ages and using some of those as standards is useful/convenient. We still use QWERTY keyboards even though our highly futuristic typewriters don't jam anymore. We type commands on tty teleTypeWriter, we save files with buttons using a floppy disk icon, etc etc.
- yunwal 24d ago> None of that matters for a phone. Of course it does. They show the most basic example right on the page, which is that you can side-by-side full screen apps.
- guyzero 24d agothis isn't great design, it's tautology. of course the phone open is twice the size of it closed. it would be hard to make it otherwise.
- deleted 24d ago[deleted]
- Nevermark 24d agoIt isn't just twice the size. Both sides have the same aspect ratio as the whole screen. > this isn't great design, it's tautology. of course the phone open is twice the size of it closed. Well, it sounds obvious now, but before Archimedes, ancient engineers split their screens 60-40, so the full screen wasn't twice the size of either side.
- guyzero 24d agoYes, I do understand the issue with the aspect ratio, which is indeed good design, but parent comment's example is that "you can run two apps side by side" is the tautology. Well, at least since the invention of double-entry bookkeeping and getting rid of Archimedian phone design.
- TulliusCicero 24d agoBut it's not really the same aspect ratio, is it? Because one is used predominantly vertically, and the other horizontally. As long as there's this landscape vs portrait difference, how does the aspect ratio similarity actually help?
- tiltowait 24d agoIf you unfold and have two apps side-by-side, then the aspect ratio (and seemingly size?) is the same as having one app, closed. Seems nice to have.
- TulliusCicero 24d agoI mean that's true for side-by-side foldables in general isn't it? It doesn't require what Apple is saying about the aspect ratio here.
- leni536 24d agoThat doesn't require a special aspect ratio.
- wittjeff 24d agoI want to be able to open the phone and get the original closed-state image, but stretched to fit the new total hardware viewport size.
- nonethewiser 24d agoYou mean unlike all of the marketing photos?
- wittjeff 24d agoYes, that's what I mean. I didn't see the desired mode in any of the marketing materials. This mode would be an effective 1.4x full-screen scaling. To be more specific: if the OS desktop has XxY virtual pixels in closed mode, if the user opens it and rotates 90 degrees, the desktop still has XxY virtual pixels. No new usable real estate. Everything previously seen just gets a bit bigger. I don't expect it to be the desired default for most people, but I have middle-aged eyes.
- nonethewiser 24d agoYou mean all two states?
- crumb-bum 24d ago[flagged]
- pkulak 24d agoToo wide to fit in anyone's pocket, but the ratio is the sine of 45 degrees! Seems like a very non-Apple thing to do, honestly. My jeans don't care about math.
- seydor 24d agoSurely the next version will unfold twice to reach A3 size
- oatmeal1 24d agoThere are compromises to any proportion decision. A tall rectangle is much more natural to hold than a fat rectangle, especially at the size of this device. The user also has to relearn the location of on screen buttons that have always had a consistent location.
- xracy 24d agoI really assumed the point of this was going to be to complain about how no phone/phone cases are exactly the same... which is an absolute scourge on society that I assume is continued by Apple here.
- peterashford 24d agoPeople mythologising Apple design will never get old
- julianlam 24d agoThe way this comment was going I was pleasantly surprised to see that the iPhone Duo adhered to the ISO standard.
- 1e1a 24d agoFrom Apple's diagonal measurements [1], it looks like the screen is actually a few mm off from the closest ISO 216 sizes. d = 7.58in = 192.532mm [1] d^2 = w^2+h^2 Unfolded: h = d/sqrt(3) = ~111.1584mm w = h*sqrt(2) = ~157.2017mm Closest ISO 216 size: A6 (105x148) Folded: D = 5.36in = 136.114mm [1] H = D/sqrt(3) = ~78.5855mm W = H*sqrt(2) = ~111.1366mm Closest ISO 216 size: A7 (74x105) [1] https://www.apple.com/iphone-duo/specs/ https://www.apple.com/iphone-duo/specs/
- rbits 23d agoI imagine that would be to account for the bezel. The outer display is slightly less than half the size of the inner display, so to get the same aspect ratio they would have to adjust it slightly.
- nsonha 24d agosounds useless and ridiculous
- nonfamous 24d agoTake a sheet of A4 paper. Fold it in half. Fold it in half again. That’s about the size of the Duo inner screen (a little larger actually, A6 is about 13% smaller than the Duo screen).
- Perepiska 23d agoThis aspect ratio is sqrt(2) - 1.4142... It is funny to calculate it from proportions of A3 and A4 formats.
