New iPhones Pro's have slightly larger screens
For the curious devs this means the effective "points" resolution of the new iPhones are 393x852 for the Pro and 430x931 for the Pro Max (3x scaled). 3 more points of horizontal room to work with, woot! More on reddit.com

iPhone 13 pro max holds the # 1 position in smartphone display
I’m genuinely surprised Samsung didn’t get first. I know they make Apple’s screens but you’d expect their own phones to have the best screens and best fine tuning with those screens. Either way got to credit Samsung for making some amazing screens. More on reddit.com

r/apple on Reddit: New iPhones Pro's have slightly larger screens
September 8, 2022 -

Small detail I haven't seen being mentioned. While both the iPhone 13 Pro and 14 Pro are being marketed as having a "6.1-inch screen", there's actually a slight difference before rounding.

  • The actual iPhone 13 Pro screen size is 6.06"

  • The estimated iPhone 14 Pro screen size is 6.12"

In practice, it's probably not going to be noticeable. It's still interesting to see the small reduction in bezel size made Apple decide to increase screen size, not reduce physical device size.

Other observations:

  • The resolution was slightly increased to match (2556×1179 vs 2532×1170).

  • Despite reducing bezel size, the new Pro's are still technically slightly bigger than their predecessor to accommodate their larger screen. They're not only thicker, but also a bit taller (5.81" vs 5.78"). Visual comparison from PhoneArena.

  • I've used the 6.1" Pro for comparison, but the same is true of the 6.7" Pro Max.

  • The regular (non-Pro) iPhone 14's on the other hand still have the same screen size as the 13.

Why does the iPhone 13 Pro Max have a few less pixels than the Pro? - Quora
12MP The screen (pixels per inch) is different. 1. 460 on the pro 2. 458 on the Pro Max Since you are human, your eyes max out at 400 PPI so don’t worry, you are safe going with either. 2 pixels per inch isn’t going to matter.
