Apple is seemingly sticking with the same screen dimensions for its upcoming iPhone 18 Pro lineup: 6.3 inches for the Pro model and 6.9 inches for the Pro Max. These matches are identical to those on the current iPhone 17 Pro and iPhone 17 Pro Max. While display size won’t be changing, Apple is reportedly exploring other screen tweaks.

No Size Change, Focus on Display Refinements
In recent months, leaks have consistently repeated the expectation that this year’s iPhone 18 Pro models will retain the 6.3-inch and 6.9-inch OLED panels already used. That stability in form comes amid rumor traffic about potential innovations in the front-camera and Face ID system.

The big question: will Apple finally move Face ID components underneath the display? One report claims that an under-display Face ID system is in the works, which could allow only a small pinhole cutout in the top left of the screen instead of the current Dynamic Island. But this claim remains disputed. Other sources believe a smaller Dynamic Island will still be part of the design, with the TrueDepth camera modules remaining exposed in some way.

Display analyst Ross Young says under-display Face ID might be technically possible for these models, but he doesn’t expect Dynamic Island to be completely removed. Bloomberg’s Mark Gurman backs that Blue Island (as some call a narrower island) is more likely than a total removal.

A leaker known as Ice Universe has tried to put numbers behind the alleged change, estimating that the Dynamic Island width could shrink by around 35%, from roughly 20.7 mm to approximately 13.5 mm. Yet these measurements are still speculative. ([macrumors.com](https://www.macrumors.com/2026/08/24/iphone-18-pro-display-sizes-what-to-expect/))
Behind the scenes, Apple is said to have been evaluating two designs: one that reuses the existing screen mold from the iPhone 17 Pro, and another that switches to a new mold allowing for a “Mini Dynamic Island” by relocating Face ID hardware beneath the display. The final decision reportedly came down to choosing between these two. ([macrumors.com](https://www.macrumors.com/2026/08/24/iphone-18-pro-display-sizes-what-to-expect/))
Launch Timing and Broader Product Strategy
The iPhone 18 Pro and Pro Max are expected to be unveiled in their usual September slot. One forecast places Apple’s event around September 9, 2026. Meanwhile, the standard iPhone 18 and the iPhone Air 2 may not arrive until about March 2027. ([macrumors.com](https://www.macrumors.com/2026/08/24/iphone-18-pro-display-sizes-what-to-expect/))
Other rumored enhancements across the Pro lineup include more miniaturized front-camera components and possibly more subtle design polish, as Apple fine-tunes what its flagship look and feel will be. The display is likely to receive modest tweaks, but any major redesign seems to be centered on slimming internal camera hardware rather than changing the face of the device radically. ([macrumors.com](https://www.macrumors.com/2026/08/24/iphone-18-pro-display-sizes-what-to-expect/))
What makes this moment interesting is that Apple appears to be balancing innovation with risk mitigation. Sticking to familiar display sizes limits engineering headaches around case compatibility and supply chain disruptions. Adding optional under-display Face ID or a smaller Dynamic Island offers a visible upgrade without radically altering the product. But it also may introduce cost or yield issues.
What to watch: whether Apple delivers under-display Face ID this year or opts for a minimized Dynamic Island. The next few weeks should yield more clarity, particularly if final mold decisions leak or early supply chain confirmations emerge. As for consumers, those hoping for bigger or radically different panels may be disappointed — but those optimistic about subtle display refinements have reason to get excited this fall.
