Video Demo of What a 4" iPhone Screen Looks Like in Action

The biggest change in the rumored new iPhone is the increase in screen size from 3.5" to 4". As we've seen in numerous part leaks, the new iPhone screen will be taller, but not wider. This will give the new device a resolution of 1136x640 and provide apps with more vertical space to use. In fact, it's been found that iOS 6's home screen already supports this larger size to display an extra row of app icons.

In order to provide a better demonstration of what a 4" iPhone screen would feel like, MacRumors has had this video created to show it in action:


The video shows how the new 4" Home Screen would look. The extra space would naturally allow for larger app folder sizes. Games and other apps would have to be modified to take advantage of the extra real estate. We imagined, however, that existing apps would be "letterboxed", simply leaving empty black space at the top and bottom of the larger screen. Apple used a similar approach when supporting iPhone apps on the iPad.

The new 1136x640 resolution is almost exactly the same 16:9 ratio found on many widescreen monitors and televisions. This will fit many widescreen movies more naturally.

Some of the behavior in the video is speculative, but we believe it is likely representative of how a 4" iPhone would work. The evidence of such a screen has been overwhelming with part leaks and evidence of iOS support. Apple is expected to launch the new iPhone on September 12th.

just curious why the odd resolution? I know it's 16:9 and everything designed around 16:9 will be in the right ratio.

But why that resolution? Why not the standard 1280x720?

The current resolution of the iPhone is 960×640. Going from 960×640 -> 1280x720 would be more awkward. Apps would have to scale in two directions.
