iPhone 18, iPhone 18 Pro and iPhone 18 Pro Max Screen Size and Specs

The iPhone 18 generation brings major updates to Apple’s display, processor, camera and connectivity technology. For people in the UK searching for the latest iPhone 18 screen size and specs, there is an important distinction: Apple has officially released the iPhone 18 Pro and iPhone 18 Pro Max, while the standard iPhone 18 has not yet been announced.

Apple introduced the Pro models on 9 September 2026, with UK availability beginning on 18 September 2026. Reports currently indicate that the standard iPhone 18 is expected to follow in spring 2027.

What Is the iPhone 18 Screen Size?

The iPhone 18 Pro has a 6.3-inch screen, while the larger iPhone 18 Pro Max has a 6.9-inch screen. Both use Apple’s Super Retina XDR OLED display technology.

For the standard iPhone 18, current reports point to a 6.3-inch display, although this remains unofficial until Apple formally announces the model. Reports also suggest a 120Hz LTPO panel and Dynamic Island.

iPhone 18 Pro Display Specifications

The iPhone 18 Pro features a 6.3-inch all-screen OLED display with a resolution of 2622 × 1206 pixels and a pixel density of 460 ppi.

Apple notes that the display measures approximately 6.27 inches diagonally when measured as a standard rectangle because the screen has rounded corners.

The iPhone 18 Pro Max increases the display to 6.9 inches, with a resolution of 2868 × 1320 pixels. It maintains the same 460 ppi pixel density.

Does the iPhone 18 Have a 120Hz Display?

The iPhone 18 Pro and iPhone 18 Pro Max both use ProMotion technology with adaptive refresh rates of up to 120Hz.

A higher refresh rate allows movement, scrolling and supported animations to appear smoother. Because the refresh rate is adaptive, the display does not have to operate at 120Hz continuously.

Apple also includes an Always-On display on both Pro models.

Reports suggest the standard iPhone 18 will also use a 120Hz LTPO display, but that specification has not yet been confirmed by Apple.

How Bright Is the iPhone 18 Screen?

The iPhone 18 Pro and Pro Max displays can reach:

The high outdoor brightness makes the display easier to see in bright conditions, while the 1-nit minimum helps provide a less intense display when using the phone in dark surroundings.

Apple also includes an anti-reflective coating and fingerprint-resistant oleophobic coating on both Pro displays.

iPhone 18 Pro and Pro Max Dimensions

Display size refers only to the diagonal measurement of the screen. The physical dimensions of the phones are different.

The iPhone 18 Pro measures 150.0 mm × 71.9 mm × 8.75 mm and weighs 211 grams.

The iPhone 18 Pro Max measures 163.4 mm × 78.0 mm × 8.75 mm and weighs 249 grams.

The Pro Max therefore offers considerably more screen area but also has a taller, wider and heavier body.

What Processor Does the iPhone 18 Use?

The iPhone 18 Pro and Pro Max are powered by Apple’s A20 Pro chip.

The chip includes a six-core CPU consisting of two high-performance cores and four efficiency cores. It is accompanied by a seven-core GPU with Neural Accelerators and a dual 16-core Neural Engine. Hardware-accelerated ray tracing is also supported.

The standard iPhone 18 is widely expected to use an A20-series processor, but Apple has not yet published its final specifications.

iPhone 18 Camera Specifications

The iPhone 18 Pro and Pro Max include Apple’s 48MP Pro Fusion camera system.

The rear camera arrangement consists of a 48MP Fusion Main camera, a 48MP Fusion Ultra Wide camera and a 48MP Fusion Telephoto camera.

One of the major camera changes is the variable aperture on the 48MP Fusion Main camera. Users can select between f/1.48, f/1.8, f/2.8 and f/4.0 aperture settings.

The Telephoto camera provides a 100 mm 4x option and also enables a 200 mm 8x optical-quality telephoto view. Digital zoom extends to 40x.

iPhone 18 Front Camera

The iPhone 18 Pro series uses an 18MP Centre Stage front camera with an f/1.9 aperture and autofocus.

It supports features including Centre Stage for photographs and video calls, Dual Capture, Night mode, Smart HDR 5, ProRAW and 4K Dolby Vision video recording.

The terminology is particularly relevant to UK specifications because Apple uses the British spelling “Centre Stage” on its UK product pages.

iPhone 18 Storage Options

Both Pro models are available with four internal storage capacities:

The available capacity now extends as high as 2TB, providing considerably more space for high-resolution photographs, applications and professional video files.

iPhone 18 Battery Life

Battery performance differs between the 6.3-inch Pro and larger 6.9-inch Pro Max.

According to Apple’s UK specifications, the iPhone 18 Pro offers up to 34 hours of video playback, while the Pro Max reaches up to 43 hours.

Both phones support fast charging. Apple states that compatible charging equipment can charge the battery to around 50% in approximately 15 minutes.

iPhone 18 Connectivity Specifications in the UK

The iPhone 18 Pro models support modern mobile and wireless connectivity technologies used in the UK, including 5G, Gigabit LTE, Wi-Fi 7 and Bluetooth 6.

They also contain Apple’s N1 wireless networking chip, second-generation Ultra Wideband technology, NFC and the Apple C2 cellular modem.

The USB-C connector supports charging, DisplayPort and USB 3 data transfer at speeds of up to 10Gb/s.

Does the UK iPhone 18 Pro Have a Physical SIM?

Yes. Apple’s UK specifications list Dual SIM using nano-SIM and eSIM, along with support for dual eSIM.

This is worth noting because SIM configurations can differ between iPhones supplied in different countries and regions.

UK users should therefore refer to Apple’s UK technical specifications rather than assuming that specifications published for US models apply identically.

Is the iPhone 18 Waterproof?

The iPhone 18 Pro and Pro Max are rated IP68 under IEC standard 60529 for splash, water and dust resistance.

An IP68 rating indicates a defined level of resistance under laboratory conditions, but it does not mean an iPhone is permanently waterproof. Water and dust resistance can decrease through ordinary wear.

What Software Does the iPhone 18 Use?

The iPhone 18 Pro generation runs Apple’s current iPhone operating system and incorporates Apple Intelligence and Siri AI features.

Apple describes the A20 Pro and its Neural Engine as central to handling advanced machine-learning and artificial-intelligence workloads on the device.

iPhone 18 Pro vs iPhone 18 Pro Max Specs

The most noticeable difference between the two confirmed iPhone 18 models is their physical size and battery performance.

The core processor, display technology, camera hardware, storage options and connectivity features are closely matched. The Pro Max primarily provides a larger display and longer rated battery life.

What About the Standard iPhone 18?

As of 22 September 2026, Apple has not officially announced the standard iPhone 18.

Current reporting indicates that Apple is splitting the iPhone 18 generation across two launch periods, with the standard iPhone 18 expected in spring 2027.

Rumoured specifications currently include:

• A 6.3-inch display
• 120Hz LTPO display technology
• Dynamic Island
• An A20-series processor
• A design broadly similar to the previous standard generation

These specifications should not yet be treated as final. Apple may change individual hardware details before the standard model is formally announced.
