Amid continuing rumors that Apple is looking to increase the size of the iPhone display from the existing 3.5-inch screen to something in the range of 4 inches, one persistent concern has been how Apple would deal with the change in screen dimensions.

All models of the iPhone and iPod touch released to date have carried a 3.5-inch screen with a 3:2 aspect ratio, allowing developers to target their apps at a single screen size. With the addition of Retina displays in 2010, the screens now come at much higher resolution, but the extra resolution is dedicated to increasing the visual quality of content rather than increasing screen real estate. The introduction of the iPad in 2010 added a new display size to the mix, but the considerable difference in screen size compared to the iPhone made it reasonable for developers to create custom interfaces, either in the form of universal apps or separate iPad and iPhone apps, for use on the different devices.

But moving to a slightly-larger iPhone display would seem to cause issues for Apple and its developers, with the company seemingly having two options: either increasing pixel size to keep the same resolution but on a slightly larger display; or maintaining pixel size and increasing resolution correspondingly. The former solution would allow existing iPhone apps to fit the new device's screen with no modifications but with only limited utility, while the latter solution would seem to require developers target yet another screen size with their apps.

But as outlined at The Verge, one method for achieving the latter solution in moving to a 4-inch display would be to change the aspect ratio, maintaining the existing 640 pixel width but stretching the height of the display until it reaches a 4-inch diagonal. Simple geometry yields a screen height of roughly 1152 pixels for a 4-inch display, compared to 960 pixels on the current 3.5-inch display.

The forum poster, a user by the name of modilwar, was inspired by a comment from a caller named "Colin" on The Vergecast show who suggested that change in aspect ratio as a possibility for a larger display. Using that idea, modilwar developed a series of illustrations showing how this could be achieved.

At the most basic level, an increase in the height of the display would allow Apple to show five rows of icons on each page of the iPhone's home screen, up from the current four rows. Apple would also likely find it fairly easy to augment its own apps to take full advantage of the increased vertical screen real estate.

As for third-party apps, modilwar notes that many apps already utilize standard interface elements such as navigation buttons and bars at the top and bottom of the screen supporting a larger main content window in the middle. In the case of these apps, the main windows could simply expand vertically to show more content than on the current iPhone. Examples include browsers that could show more of a webpage, Twitter apps that could show more of a timeline, and mapping apps that could show more map tiles.

Other apps with custom user interface elements would require a bit more work, but in the meantime could simply be displayed at their current sizes with a 96-pixel wide black bar at top and bottom on the larger 4-inch display.

This new 4-inch screen with a 9:5 aspect ratio would also perform much better at displaying widescreen 16:9 video content, leaving bars on either side of the screen that are only 7 pixels wide, compared to 50 pixels for unzoomed content on the current iPhone.

Modilwar passes off his post as an intellectual exercise simple showing one way in which Apple could make a change to the iPhone's display with a minimum of disruption to the iOS ecosystem, but in a bit of a curious turn the post was picked up by Daring Fireball's John Gruber, who hints that the original idea may not be all that far-fetched.
Methinks "Colin" wasn't merely guessing or idly speculating.
Since Gruber has been known to speak coyly about his occasional inside knowledge, it is unclear whether he has independent knowledge supporting the idea of a taller display for the iPhone or if he simply has a gut feeling that "Colin" may legitimately be tipping some information at least partially tied to Apple's thinking.

Update: "Colin" has been revealed to be Timothy Collins, who has no direct association with Apple.

I'd be all over it. I understand people like the smaller device but there's so much wasted space around the screen they could do this and not make the phone that much bigger.

Seems to me that would look silly. I mean I'll buy it, but I think it needs to get bigger in both directions (if any).

Ok. One question what is the point of having both the iPhone with bigger screen AND the iPad with a smaller one? If anything happens is one of the other not both.

Doubtful. It would fragment iOS like Android, into multiple aspect ratios and screen resolutions... causing huge headaches for developers.

This would be a complete disaster for developers, introducing not only an additional resolution, but a third aspect ratio to the iOS system. I really hope this rumor is not true. Making a 4" screen with the current 3x2 aspect and the same 960x540 resolution would be MUCH better, and should still look great whether it meets a technical "retina" threshold or not.

Increase the size to 4", keep the same resolution. Everyone will be happy other than the people using a magnifying glass to look for pixels.

Apple needs to come out w/ multiple sizes. 4 inch only and I am gone for sure.

The other thing is, what is the deal w/ the app which cannot run like in computer where it is set to run at certain size(say 3.5 for all old apps) and rest to whatever new size(say 4.5) ?? why not? I don't care if some of my apps do not run in full screen. Who really cares?

Not to say that things could change, but I remember reading in the Steve Jobs book that they chose the size they did because you can reach the entire screen using just one hand.

Just a thought!

Personally, I don't want anything larger. That's what she said.

If you know how to make layouts, that is not a big headache...
For me, animations was a bigger. Might be better with ICS, but last time I did it was with Gingerbread.

But there are other headaches... (like ANY OS or SDKs)

"Huge headaches" for developers because they have to deal with OH MY GOD TWO RESOLUTIONS?


...
Please.

Don't see this happening...

I did find the headline oddly funny though. I mean, they could "achieve" a 14 inch screen by increasing height only. :rolleyes:

I hope they take the MacBook Air route and provide 2 different sizes. Keep the 3.5" and add a 4" or 4.3" which seem to be the sweet spots for a larger mobile device.

Just continuing with the same size again would leave out alot of potential customers that are interested in a larger device, for example someone with larger hands like myself that goes to Android to find a screen size that suits me better. But would love to use iOS device as a primary device.

I agree. I don't like that Android phones are all going the 4.7"+ route and I'm not fond of the current iPhone's tiny screen. I just want to meet in the middle!

Black bars just scream "Apple polish", eh?

5 or 6 screen sizes can hardly be considered fragmentation compared to An**oid with dozens of different displays and more coming every day.
