The Apple iPhone X in 2017 heralded the end of the old 16:9 displays and 19.5:9 became the new standard. The current iPhone 14 series still uses this aspect ratio and the iPhone 15 series will stay with it as well. The Apple iPhone 16 Pro, on the other hand, could break with the old tradition.

According to Display Supply Chain Consultants analyst Ross Young, the Apple iPhone 16 Pro and 16 Pro Max will move to a larger aspect ratio. So far, however, it is not clear how much larger. Likely options are 20:9 or 20.5:9. The diagonals grow slightly from 6.1 to 6.2 inches on the Pro and from 6.7 to 6.8 inches on the Pro Max.
The change only affects the iPhone 16 Pro models, at least for the time being. The regular iPhone 16 and 16 Plus will have to wait a few more years for the update. For the iPhone 15 and 15 Plus, the switch to Dynamic Island is planned for 2023. You can see all major changes in the timeline above. In addition, LTPO displays and thus refresh rates of 120 Hz are added to the basic models. The new aspect ratio will also end up in the two cheap iPhones at some point. Here you can find all previous rumors about the iPhone 15.
Based on Young’s assessment, Apple will only update the Dynamic Island design with the iPhone 17 Pro and 17 Pro Max. The Face ID system then moves under the display, leaving only a small punchhole for the selfie camera.
