Throughout the entire rumor cycle for this year’s new iPhones, we’ve been inundated with reports of two new screen sizes, 4.7 and 5.5 inches. But while the physical sizes of these displays leaked early and often, the exact pixel dimensions have not.

At this point, there’s too much smoke around the “two new iPhones, 4.7- and 5.5-inch” narrative for there not to be a fire. I think that’s what Apple is planning to announce next month — not because anyone “familiar with the plans” has told me so, but simply because so many parts have leaked corroborating these two sizes.

I’ve spent much of the last month trying to figure out the pixel counts for these displays, and it’s actually quite tricky. When Apple changed the iPhone display previously, they did so in obvious ways. With the iPhone 4’s retina display, Apple kept the physical size exactly the same (3.5 inches) and exactly doubled the pixels-per-inch resolution. When the iPhone 5 increased the size to 4 inches and the aspect ratio (switching from 3:2 to 16:9), they simply added pixels vertically. Same pixels-per-inch resolution, same width (640 pixels), new height (1136 pixels instead of 960).

There is no similar “easy” way to do either a 4.7 or 5.5 iPhone display.
