What is the resolution of iphone x. iPhone XS vs XS Max vs XR: Display Size and Resolution in Inches

Today, thanks to TENAA documents, the new iPhone 8 and iPhone 8 Plus smartphones received smaller batteries compared to their predecessors. We don’t know yet what capacity the battery is installed in the iPhone X, but we can tell you another, no less interesting fact. It turns out that the 5.8-inch display on the anniversary iPhone X is actually "smaller" than the 5.5-inch screen on the iPhone 8 Plus. This paradox is due to differences in displays.

As you know, with the release of the new iPhone X smartphone, Apple has joined many other manufacturers who have already managed to transfer their flagships to the so-called “frameless” design by marketers. The device received an unusually shaped display with thin bezels and a cutout for the TrueDepth camera system and other sensors. At the same time, the screen of the iPhone X turned out to be more elongated in height and is characterized by a resolution of 2436x1125 pixels, which corresponds to an aspect ratio of 2.17:1. At the same time, the iPhone 8 Plus model is equipped with a "regular" screen without any cutouts with a resolution of 1920x1080 pixels with an aspect ratio of 16:9. Actually, this difference leads to an unexpected result when calculating the effective screen area.

Apple uses dots as an absolute reference, so let's follow suit and not delve into the nuances associated with differences in resolution, since this is a completely different topic. We are also interested in a purely "clean" screen size.

So, 2436x1125 pixels corresponds to 812x375 pixels (3x magnification factor) in case of iPhone X and 736x414 pixels in case of iPhone 8 Plus (2208x1242 pixels).

To start with, you can use a simplified model and calculate the effective screen area, ignoring the large notch and curved edges of the iPhone X display. For a more complete picture, you can also calculate the screen area for the iPhone 8. The iPhone X screen area is approximately 375 * 812 = 304500 pixels , while the exact area of ​​iPhone 8 Plus and iPhone 8 is 304704 (414 * 736) dots and 250125 (375 * 667) dots, respectively. And without subtracting the cutout area from the iPhone X result, you can see that the iPhone 8 Plus has a large display area.

To find out how much more specifically, there are a few more mathematical calculations to be done. More specifically, it is necessary to calculate the exact area of ​​the cutout and the exact area of ​​the corners of the screen. Fortunately, knowing the radii of the curves, it is possible to do this. The source cites images of smartphone screens with all sizes and calculations, there is no point in reprinting them. Note that after subtracting the extra zones and adding the area of ​​​​the corners, the net area of ​​\u200b\u200bthe iPhone X came out equal to 296724 points. Thus, the screen area of ​​the iPhone X is 97.38% of the area of ​​the iPhone 8 Plus. In other words, the iPhone X screen is 2.6% smaller than the iPhone 8 Plus screen. The image below shows the iPhone X display on top of the iPhone 8 Plus screen to see the difference.
