How do the iPhone 15 and iPhone 16 screens compare?
Every screen measurement side by side. Width and height are worked out from each diagonal and resolution. Brightness is from Apple's tech specs, and viewport and pixel ratio from Apple's Xcode device profiles.
What is the real difference between the iPhone 15 and iPhone 16?
The two screens match exactly, so photos, apps and websites look the same size on both. The iPhone 15 Pro and 14 Pro use the same screen too. The choice between them comes down to the rest of the phone, not the screen.
The iPhone 16 came out a year after the iPhone 15, as its direct successor. Across our list of thirty-nine iPhones, seventeen have a bigger screen than either.
Websites see the same viewport on both, so a page lays out exactly the same. Both are sharp enough that single pixels vanish well before the distance you hold a phone at.
Apple lists the same typical, HDR and outdoor brightness for both, so neither is easier to read in sun. Apple lists a lowest brightness only for the iPhone 16, a setting meant for reading in the dark.

Both phones measure 5.81 × 2.82 × 0.31 in (147.6 × 71.6 × 7.80 mm), height by width by depth.
The same outside size does not mean a case fits, because camera and button cutouts can differ. The iPhone 15 is 1 g (0.02 oz) heavier.
