How Apple Could Make a 4-Inch iPhone

“Modilwar”, in a well-illustrated piece on The Verge forums:

But then last week, while watching the Vergecast episode 24, came the Eureka moment. A caller named Colin (apologies if I got your name wrong) mentioned how he thought apple could increase the iPhone screen size without effecting the external form factor or pixel density. […]

Colin’s idea was to keep the shorter side of the iPhones screen the same, i.e. 640 pixels at 1.94 inches. With that in mind how much would the longer side need to increase so the that diagonal measurement was 4 inches. The answer, derived using simple algebraic rearrangement of Pythagorus’s theorem, 1152 pixels and 3.49 inches. That leaves the the diagonal length measuring a little over 3.99 inches, I’m sure Apple PR could round this 4.

For those of you who are good with numbers I’m sure you’ve noted that 1152 × 640 has an aspect ratio of 9:5 and the 1152 pixels is and increase of 192 from 960 and that’s 20% more than on the iPhone 4 and 4S.

Methinks “Colin” wasn’t merely guessing or idly speculating.
