John Gruber Predicts the Optimum 4.7″ and 5.5″ iPhone 6 Display Resolutions



Daring Fireball’s John Gruber has predicted the optimum resolutions of Apple’s rumoured 4.7 and 5.5-inch iPhone 6 models.

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 inches1) 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).

Gruber predicts that the 4.7-inch model of the iPhone 6 will come with a resolution of 1334 x 750 at 326 pixels per inch, making it double the resolution of Apple’s current generation Retina displays.

On the other hand, he predicts that the 5.5-inch model of the iPhone 6 will come with a display resolution of 2208 x 1242 at 461 pixels per inch, making it triple the resolution of Apple’s current Retina displays.

The display resolutions for both rumoured models of the iPhone are complete estimates on Gruber’s part and he said, “No one who is truly “familiar with the situation” has told me a damn thing about either device”. Find out how Gruber came up with these numbers by reading his explanation from his article.

Apple is expected to launch the iPhone 6 at an event rumoured for September 9. The company’s next-generation smartphone is rumoured to come in two display sizes, a 4.7-inch model and a 5.5-inch model.

It is still unclear whether Apple will launch both models during their rumoured media event in September, or if the 4.7-inch iPhone will make its appearance first with the 5.5-inch model following later this year.

The iPhone 6 is said to come with a completely new design, Apple’s next-generation 64-bit A8 processor, 1GB of RAM, and a much improved camera with optical image stabilization.

    I doubt they will announce both at the same time. If they announce both but release one first, it will hurt the sales of the first one because people will want to compare side by side before making a decision.

    The downside is, if they don’t mention the 5.5inch at all, people will think apples not releasing a second larger phone and end up buying the 4.7inch. Now if the larger one ends up being real and is announced and released later this year, alot of people will be angry for settling with the 4.7inch. Kijiji will probably flood with discounted 4.7inch iPhones, which will only hurt apples sales in the end.

    Personally, I hope they announce both at the same time.

    I think the 5.5″ rumor that’s floating around is just a bunch of BS. It really doesn’t make any sense to release such a huge monstrosity of a phone, especially since there really isn’t a huge demand for it.

    Could be true, but fortunately for apple; I think I would buy it! I’ll take the largest available.
