A reputable leaker has detailed the screen sizes and display technology for Apple's upcoming iPhone 18 lineup, confirming no changes to physical dimensions while hinting at a significant redesign for the Dynamic Island on Pro models.
Eight months ahead of its expected unveiling, the iPhone 18 lineup is already taking shape in the supply chain. Leaker Digital Chat Station, known for accurate supply chain information, has shared detailed specifications for the upcoming models, focusing on screen sizes and the evolution of the Dynamic Island. The information suggests Apple is maintaining its current form factors while reserving a key display innovation for its premium Pro models.
Consistent Dimensions and Display Technology
The leaked specifications point to a familiar set of screen sizes for the standard iPhone 18 models. According to the translated post, the lineup will be:
- iPhone 18: 6.27-inch LTPO 120Hz screen with Dynamic Island
- iPhone Air 2: 6.55-inch LTPO 120Hz screen with Dynamic Island
- iPhone 18 Pro: 6.27-inch LTPO 120Hz screen with new under-display area
- iPhone 18 Pro Max: 6.86-inch LTPO 120Hz screen with new under-display area
These dimensions align perfectly with the current iPhone 17 lineup, indicating Apple is not pursuing any physical size changes for this generation. The display technology also remains consistent, with all models featuring LTPO (Low-Temperature Polycrystalline Oxide) panels capable of 120Hz refresh rates. This technology allows for variable refresh rates, which helps conserve battery life by lowering the refresh rate for static content.
The lack of size changes is a pragmatic choice for Apple. Changing display dimensions would require extensive redesigns of internal components, cases, and accessories, creating unnecessary complexity for both Apple and its ecosystem partners. By maintaining the established form factors, Apple ensures backward compatibility with existing accessories and provides a familiar user experience.
The Dynamic Island Divide
Where the leaks become particularly interesting is with the Dynamic Island. For the past few years, Apple's pill-shaped cutout has been a defining feature across its entire iPhone lineup, from the base model to the Pro Max. This may change with the iPhone 18.
Digital Chat Station indicates that the standard iPhone 18 and iPhone Air 2 will retain the current Dynamic Island design. This suggests Apple is keeping the proven, functional cutout for its more affordable models, likely to maintain cost efficiency and manufacturing simplicity.
However, the iPhone 18 Pro and iPhone 18 Pro Max are described as having a "new under-display area." The leaker notably avoids using the term "Dynamic Island" for these models, which is a significant departure from current naming conventions. This omission hints that the Pro models may be moving toward a fundamentally different design.
Two Possible Directions for Pro Models
Industry rumors have presented two conflicting theories about what this new cutout will look like:
A Reduced Dynamic Island: The pill-shaped cutout could simply shrink in size, becoming less prominent while maintaining the same functional area for Face ID sensors and the front camera.
A Hole-Punch Design: A more radical change would be moving to a simple circular or oval hole-punch cutout, potentially offset to the top-left corner of the display. This would represent a significant visual departure and could allow for more screen real estate.
The leaker's specific wording—"new under-display area" rather than "new Dynamic Island"—leans toward the second possibility. If Apple were merely shrinking the existing Dynamic Island, they would likely still refer to it as such. The change in terminology suggests a more fundamental redesign.
This Pro-exclusive feature follows Apple's established pattern of reserving key innovations for its premium models. Just as the iPhone 15 Pro introduced the Action Button and the iPhone 16 Pro is rumored to get a dedicated camera button, the iPhone 18 Pro may pioneer a new approach to front-facing sensor integration.
Developer and Ecosystem Implications
For iOS developers, these display changes have practical implications. If the Pro models adopt a hole-punch design, apps will need to account for a different cutout shape and position. While Apple's Safe Area APIs handle most edge cases, developers who have carefully optimized their UIs around the current Dynamic Island may need to adjust layouts, especially for full-screen content like videos and games.
The consistent LTPO 120Hz technology across all models is good news for developers. It means they can rely on high refresh rate displays being available on every iPhone 18 model, allowing them to design fluid animations and interactions without worrying about fragmentation. This consistency simplifies development and testing.
For accessory manufacturers, the unchanged screen sizes mean existing cases and screen protectors for iPhone 17 models may be compatible with iPhone 18 models, depending on camera module changes. However, the potential redesign of the Dynamic Island on Pro models could require new case designs that accommodate the different cutout shape.
What This Means for the iPhone 18 Launch
The iPhone 18 lineup, expected to be announced in September 2026, appears to be following Apple's typical refinement cycle. Rather than radical external changes, Apple seems focused on internal improvements and reserving display innovation for its premium tier.
This strategy makes business sense. By keeping the standard models familiar, Apple reduces manufacturing complexity and maintains price points. Meanwhile, the Pro models can justify their premium pricing with exclusive features like a redesigned front display area.
The potential hole-punch design on Pro models would also align with industry trends. Many Android manufacturers have already moved to hole-punch or under-display camera solutions, and Apple is typically conservative but deliberate in adopting such technologies. By 2026, under-display Face ID technology may have matured enough for Apple to implement it reliably.
Looking Ahead
As we approach the iPhone 18 launch, expect more details to emerge about this new under-display area. The key questions will be:
- Will it be a hole-punch or a shrunken Dynamic Island?
- How will it affect the usability of the front-facing camera and Face ID?
- Will the standard models eventually adopt this design in future generations?
For now, developers and users can at least plan for consistent screen sizes and display technology across the iPhone 18 lineup, with the Pro models potentially offering a glimpse into Apple's next evolution of front-facing sensor integration.
The iPhone 18 Pro is rumored to feature a new under-display area, potentially moving away from the current Dynamic Island design.
Current Dynamic Island technology may evolve differently for Pro models, while standard models retain the existing design.
Screen sizes are expected to remain consistent with the iPhone 17 lineup.
The iPhone 18 lineup is expected to launch in September 2026.
