The iPhone 18 generation introduces important changes to Apple’s display, processing, camera and connectivity hardware. As of September 2026, Apple has officially announced the iPhone 18 Pro and iPhone 18 Pro Max, while the standard iPhone 18 has not yet been announced. Reports indicate that the regular model is expected in early 2027, so its specifications should still be treated as unconfirmed.
This guide explains the iPhone 18 screen sizes, display technology, dimensions, processor, cameras, storage, battery performance and other important specifications using confirmed information where available.
What Is the iPhone 18 Screen Size?
The officially released iPhone 18 Pro has a 6.3-inch Super Retina XDR OLED display, while the larger iPhone 18 Pro Max uses a 6.9-inch Super Retina XDR OLED display. Both screens support ProMotion with adaptive refresh rates up to 120Hz, Always-On display technology, HDR and True Tone.
The standard iPhone 18 is currently reported to use a 6.3-inch display, but Apple has not confirmed this specification because the regular model has not yet been formally introduced. Current reports also point to a 120Hz LTPO panel and Dynamic Island for the standard model.
| iPhone 18 Model | Screen Size | Display Type | Refresh Rate | Status |
| iPhone 18 | Expected 6.3 inches | Expected OLED/LTPO | Expected up to 120Hz | Not yet confirmed |
| iPhone 18 Pro | 6.3 inches | Super Retina XDR OLED | Adaptive up to 120Hz | Confirmed |
| iPhone 18 Pro Max | 6.9 inches | Super Retina XDR OLED | Adaptive up to 120Hz | Confirmed |
iPhone 18 Pro Display Specifications Explained
The iPhone 18 Pro combines its 6.3-inch OLED panel with a resolution of 2622 × 1206 pixels at 460 pixels per inch. Apple notes that when the rounded display is measured as a standard rectangle, its diagonal measurement is approximately 6.27 inches.
The iPhone 18 Pro Max increases the screen to 6.9 inches and uses a resolution of 2868 × 1320 pixels at 460 ppi. The larger display provides more physical screen area without reducing pixel density.
Both models also include a smaller Dynamic Island, while retaining Face ID functionality. Apple lists Always-On display, ProMotion, HDR, wide P3 colour, Haptic Touch and an anti-reflective coating among the display features.
| Display Specification | iPhone 18 Pro | iPhone 18 Pro Max |
| Display size | 6.3 inches | 6.9 inches |
| Panel | Super Retina XDR OLED | Super Retina XDR OLED |
| Resolution | 2622 × 1206 | 2868 × 1320 |
| Pixel density | 460 ppi | 460 ppi |
| Refresh rate | Adaptive up to 120Hz | Adaptive up to 120Hz |
| Always-On display | Yes | Yes |
| HDR | Yes | Yes |
| Dynamic Island | Yes | Yes |
| True Tone | Yes | Yes |
How Bright Is the iPhone 18 Display?
Apple specifies up to 1,000 nits typical maximum brightness, 1,600 nits peak HDR brightness and 3,000 nits peak outdoor brightness for the iPhone 18 Pro displays. The panels can also reduce brightness to as little as 1 nit.
Higher outdoor brightness is particularly useful when viewing the screen under strong daylight, while the low minimum brightness helps reduce glare when using the phone in dark environments. HDR brightness is mainly relevant when displaying compatible photos and video with a wider brightness range.
iPhone 18 Pro and Pro Max Size and Dimensions
Screen size and physical phone size are not the same measurement. The 6.3-inch and 6.9-inch figures describe the diagonal display measurement, while the overall dimensions describe the complete body of the phone.
The iPhone 18 Pro measures 150.0 mm tall, 71.9 mm wide and 8.75 mm deep, with a weight of 211 grams. The iPhone 18 Pro Max measures 163.4 mm tall, 78.0 mm wide and 8.75 mm deep, weighing 249 grams.
| Specification | iPhone 18 Pro | iPhone 18 Pro Max |
| Height | 150.0 mm | 163.4 mm |
| Width | 71.9 mm | 78.0 mm |
| Depth | 8.75 mm | 8.75 mm |
| Weight | 211 g | 249 g |
| Display | 6.3 inches | 6.9 inches |
The Pro Max therefore provides significantly more display area, although it also has a larger and heavier chassis.

iPhone 18 Processor and Performance Specifications
The iPhone 18 Pro and iPhone 18 Pro Max use Apple’s A20 Pro chip. The processor includes a six-core CPU with two high-performance cores and four efficiency cores, along with a seven-core GPU featuring Neural Accelerators.
Apple also includes a dual 16-core Neural Engine and hardware-accelerated ray tracing. These components handle general processing, graphics workloads, machine-learning tasks, Apple Intelligence features and demanding applications.
The standard iPhone 18 processor has not yet been officially specified by Apple.
iPhone 18 Camera Specifications
Apple has equipped the iPhone 18 Pro models with a 48MP Pro Fusion camera system. The main 48MP Fusion camera introduces a variable aperture with settings of f/1.48, f/1.8, f/2.8 and f/4.0, giving the camera greater control over the amount of light reaching the sensor.
The camera system also includes a 48MP Fusion Ultra Wide camera and a 48MP Fusion Telephoto camera. The telephoto system provides a 4x 100 mm option and also enables an optical-quality 8x 200 mm view. Digital zoom extends to 40x.
| Camera | iPhone 18 Pro / Pro Max Specification |
| Main camera | 48MP Fusion |
| Main aperture | Variable: f/1.48, f/1.8, f/2.8, f/4.0 |

| iPhone 18 Pro Max | 256GB, 512GB, 1TB, 2TB |
The 2TB configuration provides considerably more local storage for high-resolution photos, ProRes video and large applications than previous lower-capacity configurations.
iPhone 18 Battery and Charging Specifications
Apple rates the iPhone 18 Pro for up to 36 hours of video playback and up to 33 hours of streamed video playback. The iPhone 18 Pro Max increases those figures to as much as 45 hours of video playback and 40 hours of streamed playback.
Both models support fast wired charging. Apple states that the battery can reach around 50% charge in approximately 15 minutes when used with appropriate 60W-capable charging hardware. MagSafe and Qi2 wireless charging are supported at up to 25W.
| Battery Feature | iPhone 18 Pro | iPhone 18 Pro Max |
| Typical use | Up to 24 hours | Up to 30 hours |
| Video playback | Up to 36 hours | Up to 45 hours |

iPhone 18 Water and Dust Resistance
The iPhone 18 Pro and Pro Max carry an IP68 rating under IEC standard 60529. Apple specifies resistance at a maximum depth of six metres for up to 30 minutes under controlled laboratory conditions.
Water resistance should not be interpreted as complete waterproofing. Resistance can also decrease over time because of normal wear.
What Operating System Does the iPhone 18 Use?
The iPhone 18 Pro and iPhone 18 Pro Max ship with iOS 27. The software integrates the latest Apple Intelligence capabilities and Siri AI alongside Apple’s standard iPhone privacy, communication, productivity and accessibility features.
