alt Hacker NewsThere’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.

I always forget the US doesn't use A4 etc. (or do you?)
The way this comment was going I was pleasantly surprised to see that the iPhone Duo adhered to the ISO standard.
But 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?
I 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.
Too 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.
This aspect ratio is sqrt(2) - 1.4142...
It is funny to calculate it from proportions of A3 and A4 formats.
That's not far off the 4:3 of the Samsung Z fold 8. Around 4.24:3.
People mythologising Apple design will never get old
There 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.
Take 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).
Surely the next version will unfold twice to reach A3 size
You mean all two states?
sounds useless and ridiculous

It 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.
