For users looking to purchase a pre-owned device, upgrade their current phone, or simply find a protective case that fits perfectly, understanding the precise size of the iPhone 11 Pro is essential. Released in late 2019, the iPhone 11 Pro occupies a unique space in Apple’s history as the last flagship "Pro" model to feature a 5.8-inch display before the industry-wide shift toward larger 6.1-inch standards.

Quick Summary of iPhone 11 Pro Dimensions

The iPhone 11 Pro is characterized by its compact yet dense build. Below are the official measurements provided by Apple:

  • Height: 5.67 inches (144.0 mm)
  • Width: 2.81 inches (71.4 mm)
  • Depth: 0.32 inch (8.1 mm)
  • Weight: 6.63 ounces (188 grams)
  • Display Size: 5.8 inches (diagonal)

Compared to modern smartphones, the iPhone 11 Pro is often described as a "compact flagship," offering a high-performance experience in a chassis that remains remarkably easy to operate with one hand.

Detailed Physical Specs and Build Quality

The size of the iPhone 11 Pro is only one part of its physical identity; the materials used play a significant role in how that size is perceived by the user. While the base iPhone 11 utilized aerospace-grade aluminum, the iPhone 11 Pro was built with a surgical-grade stainless steel frame.

Height and Width: The "Sweet Spot" for Ergonomics

Standing at 144.0 mm, the iPhone 11 Pro is significantly shorter than the standard iPhone 11 (which stands at 150.9 mm). This height reduction makes a noticeable difference when the phone is placed in a front pocket or a small clutch. The width of 71.4 mm is also optimized for the average human palm. In ergonomics testing, a width under 72 mm is generally considered the threshold for comfortable one-handed thumb reach across the entire keyboard.

Depth and the Camera Bump

At 8.1 mm thick, the iPhone 11 Pro was slightly thicker than its predecessor, the iPhone XS (7.7 mm). This increase in depth was a strategic choice by Apple to accommodate a much larger battery and the new triple-camera system. It is important to note that the 8.1 mm measurement refers to the chassis itself; the square camera housing on the rear adds approximately 1.5 mm to 2 mm of additional protrusion. When choosing a case, users must ensure the "lip" of the case is deep enough to protect these three prominent lenses.

The Weight Factor: 188 Grams of Density

One of the most surprising aspects of the iPhone 11 Pro size is its weight. Despite being smaller than the standard iPhone 11, it weighs almost the same (188g vs. 194g). This is due to the high density of the stainless steel frame and the frosted matte glass back. In hand, the device feels "expensive" and "solid" rather than light and plasticky. For some users, this weight provides a sense of security; for others, it might feel heavy during long periods of reading or one-handed scrolling.

The 5.8-Inch Super Retina XDR Display

The screen of the iPhone 11 Pro is where size meets high-end technology. While 5.8 inches might sound small by today's standards—where 6.7-inch screens are common—the quality and pixel density of this panel remain competitive.

Understanding the Diagonal Measurement

The 5.8-inch figure represents the diagonal distance from one corner of the screen to the opposite corner. However, because the iPhone 11 Pro features rounded corners that follow a curved design, the actual viewable area is slightly less than a standard 5.8-inch rectangle. Apple officially notes that when measured as a standard rectangular shape, the screen is actually 5.85 inches diagonally.

Resolution and Aspect Ratio

The display features a resolution of 2436-by-1125 pixels at 458 pixels per inch (ppi). This high pixel density means that despite the smaller physical size, the screen can display incredibly sharp text and vivid imagery. The aspect ratio is roughly 19.5:9, a tall and narrow format that allows the phone to remain slim (71.4 mm wide) while maximizing vertical content for social media feeds and web browsing.

The Impact of the Notch

When considering the screen size, one cannot ignore the "notch" at the top. This cutout houses the TrueDepth camera system for Face ID, the infrared camera, and the earpiece. While it does occupy a portion of the 5.8-inch area, the software compensates by pushing status icons (time, Wi-Fi, battery) to the "ears" on either side of the notch. In real-world video playback, the 19.5:9 aspect ratio means that most 16:9 content will have black bars on the sides, effectively avoiding the notch unless the user chooses to "zoom to fill."

iPhone 11 Pro vs. iPhone 11: Clearing the Confusion

A common point of confusion for consumers is the size difference between the standard iPhone 11 and the iPhone 11 Pro. Contrary to what the "Pro" name might suggest, the Pro model is actually the smaller of the two.

Specification iPhone 11 iPhone 11 Pro
Display Size 6.1-inch LCD 5.8-inch OLED
Height 150.9 mm 144.0 mm
Width 75.7 mm 71.4 mm
Depth 8.3 mm 8.1 mm
Weight 194 grams 188 grams
Bezel Size Thicker (LCD limitation) Slimmer (OLED technology)

The standard iPhone 11 uses a Liquid Retina HD display (LCD), which requires thicker bezels (the black borders around the screen) to house the backlight. The iPhone 11 Pro uses an OLED panel, which allows the screen to extend closer to the edges of the device, resulting in a much higher screen-to-body ratio.

Comparison with the iPhone 11 Pro Max

For those who prioritize screen real estate over portability, the iPhone 11 Pro Max was the larger sibling. While both phones share identical internal processors and camera systems, their physical footprints are vastly different.

  • iPhone 11 Pro Max Height: 158.0 mm (compared to 144.0 mm)
  • iPhone 11 Pro Max Width: 77.8 mm (compared to 71.4 mm)
  • iPhone 11 Pro Max Display: 6.5 inches

The Pro Max is a two-handed device for most users. If you have smaller hands or prefer fitting your phone into a standard jeans pocket without it peeking out, the 5.8-inch iPhone 11 Pro is the superior choice. However, the Max model offers significantly more room for mobile gaming and video editing.

How the Size Compares to Modern iPhones

If you are coming from an older device or considering moving to a newer one, seeing how the iPhone 11 Pro stacks up against current models is helpful.

iPhone 11 Pro vs. iPhone 13/14/15 Pro

Starting with the iPhone 12 Pro, Apple increased the standard Pro screen size from 5.8 inches to 6.1 inches.

  • iPhone 15 Pro Size: 146.6 mm x 70.6 mm x 8.25 mm. Interestingly, while the screen grew to 6.1 inches on the newer models, the physical width actually decreased slightly because of even thinner bezels. However, the iPhone 11 Pro remains shorter (144.0 mm vs 146.6 mm), making it feel slightly more compact in terms of vertical reach.

The Pocketability Test

In our practical testing, the iPhone 11 Pro remains one of the most "pocketable" iPhones ever made. Because the edges are rounded (unlike the flat, sharp edges of the iPhone 12 through 14), the phone slides in and out of tight pockets with very little resistance. Modern iPhones with flat edges tend to "catch" on fabric more easily, which makes the 11 Pro's 144 mm height feel even more manageable in daily use.

Design Details and Their Influence on Size Perception

The physical dimensions of a phone are fixed, but design choices can change how big the phone feels.

Matte Glass and Grip

The iPhone 11 Pro introduced the frosted matte glass back. Compared to the glossy glass on the iPhone 11 or the older iPhone XS, this texture is significantly less slippery if your hands are slightly damp, but can feel more "silky" and prone to sliding if your hands are very dry. The matte finish also does an excellent job of hiding fingerprints, which keeps the device looking slim and clean without the visual "bulk" of smudges.

Stainless Steel Curves

The rounded stainless steel rails are a hallmark of this generation. These curves make the 71.4 mm width feel narrower than it actually is. In contrast, a flat-edged phone with the same width would feel "wider" because the corners press more firmly into the palm. This is why many enthusiasts still prefer the ergonomics of the 11 Pro over the newer, more industrial designs.

Accessory and Case Compatibility

Because the iPhone 11 Pro has very specific dimensions and a unique triple-camera layout, you must use cases designed specifically for this model.

  1. iPhone XS Cases Will Not Fit: Although the iPhone XS also has a 5.8-inch screen, its camera bump is much smaller and oriented vertically. The massive square housing of the 11 Pro will not fit into an XS case.
  2. iPhone 11 Cases Will Not Fit: The standard iPhone 11 is much larger in every dimension (height, width, and depth). An 11 Pro would literally rattle around inside a standard 11 case.
  3. Screen Protectors: While the screen is 5.8 inches, the notch and bezel placement are specific to the 11 Pro. Always look for "iPhone 11 Pro" specific tempered glass to ensure the Face ID sensors are not obstructed.

Is the iPhone 11 Pro Size Right for You?

Choosing a phone size is a subjective decision, but the iPhone 11 Pro targets a specific demographic:

  • Choose the iPhone 11 Pro if: You want a flagship camera and a premium build but find modern 6.7-inch phones too bulky. You value being able to reach the top corner of the screen with one thumb. You prefer the "dense" feel of stainless steel over light aluminum.
  • Avoid the iPhone 11 Pro if: You consume hours of video content daily and need a massive canvas. You have very large hands and find the keyboard cramped. You prioritize the absolute lightest device possible (in which case a model like the iPhone 13 mini or a standard aluminum model would be better).
