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.
