Apple is reportedly experimenting with significantly larger iPhone displays for a special 20th anniversary model expected in 2027. If the rumor proves accurate, the change would represent one of the biggest screen-size increases Apple has considered in several years.
A Chinese leaker known as Digital Chat Station posted that Apple is sampling two new panel sizes: one around 6.4 inches and another close to 7 inches. Those dimensions would push the anniversary iPhone beyond the largest screens currently offered on Apple’s lineup, marking a new high-water mark for iPhone display size.
What’s being tested, and why it’s not confirmed yet
For context, the current iPhone 17 Pro features a 6.3-inch display while the Pro Max comes with a 6.9-inch screen. The alleged 6.4- and roughly 7-inch panels would therefore be modest increases relative to those models, but any change to Pro-class display sizes is noteworthy because Apple has not enlarged its Pro screens since the 2024 update. Back then, the Pro grew from 6.1 to 6.3 inches and the Pro Max increased from 6.7 to 6.9 inches.
Reports about the anniversary model also suggest a refreshed look that pairs larger screens with a nearly bezel-free design and gently curved edges on all four sides. Similar curved-display elements have been discussed in relation to recent mockups and early testing for this year’s models, which implies some of the required manufacturing techniques may already be maturing. Sources indicate the aspect ratio would remain consistent with current iPhones, meaning the device would likely appear as a scaled-up version of the existing shape rather than an entirely new form factor.
It’s important to treat these details as preliminary. The information originates from a single social-media tip and has not been endorsed or confirmed by Apple. Leaks at this stage can change substantially—or disappear—well before a final product ships, and Apple often iterates on designs many times during development.
The rumored anniversary handset remains more than a year away from any expected release, and Apple has reportedly been preparing a significant redesign for that milestone model for some time. Even so, plans for major launches are frequently revised, and features that appear in early samples or engineering prototypes don’t always make it into the production devices. Consider the reported panel sizes only as an early sign of possible direction, not as a final specification.
These rumors do not apply to Apple’s near-term 2026 iPhone lineup, which is expected to debut next month and is widely believed to stick with the same screen sizes used in recent models. If you are shopping for a new phone soon, the speculation about a bigger anniversary display shouldn’t be the basis for immediate decisions.
Historically, Apple has used anniversary editions to introduce major changes that later influence the broader product line. The iPhone X, released for the 10th anniversary, brought a dramatically different front design and Face ID to the iPhone family. A larger screen combined with a more dramatic shape could follow a similar pattern in 2027, but many steps remain between the earliest prototype tests and a consumer-ready release.
In short, sampling of larger displays suggests Apple is exploring new sizes for its 20th anniversary iPhone, but the rumor is early and unconfirmed. Keep an eye on future reports for stronger evidence as the development process continues and more reliable sources weigh in.
