The iPhone X introduced a new design language for Apple, and its physical footprint differs noticeably from older iPhone models. This evergreen overview explains the iPhone X display size, overall dimensions, and weight, and places those numbers in practical terms for real world use. Whether you are evaluating one handed reach, comparing cases or accessories, or simply want reliable numbers, the details below focus on verified specifications and long term relevance.
Display Size and Viewable Area
Measured Diagonally
The iPhone X features a 5.8 inch display measured diagonally, in line with Apple’s “Super Retina” OLED panel. While the number is modest by today’s standards, the near edge to edge design and minimal bezels make it feel larger in the hand than the nominal diagonal suggests.
Resolution and Pixel Density
With a resolution of 2436 by 1125 pixels, the iPhone X offers a pixel density of approximately 458 pixels per inch. This ensures sharp text and images, which remains useful for reading, browsing, and media consumption even several years after launch.

Physical Dimensions
Height, Width, and Depth
In the hand, the iPhone X measures 143.6 millimeters in height (5.65 inches), 70.9 millimeters in width (2.79 inches), and 7.7 millimeters in depth (0.30 inches). These dimensions reflect the glass and stainless steel build, with a relatively flat back that enables easy case fitting.
Weight
The iPhone X has a listed weight of 174 grams (6.1 ounces). That places it noticeably heavier than many mainstream phones today, but comparable to other premium glass devices of its era. Balance and heft contribute to a solid, substantial feel.

Practical Implications of Size
One Handed Use
With a width close to 71 mm, the iPhone X sits at the upper bound of comfortable one handed use for many people, especially those with smaller hands. Reaching the top edge often requires a thumb or a shift in grip, which is a common consideration when choosing a phone for daily carry.
Cases and Accessories
The consistent dimensions mean that cases and screen protectors designed for the iPhone X remain widely available. Because the chassis is relatively thin and flat, there is minimal bulk added by protective shells, and most mainstream accessory types fit without issue.
Display Scaling and Readability
Default and Zoom Options
iOS offers display zoom, allowing users to switch between a standard 3x layout and a more spacious 2x appearance. This adjusts the effective pixels and can make text and icons larger, improving readability without changing the native 2436 by 1125 resolution.
Text Size and Dynamic Type
Beyond zoom, Dynamic Type lets users adjust text size system wide. Combined with bold text options, this ensures that the iPhone X remains comfortable for extended reading sessions, even with its relatively high pixel density.
Comparative Context
Placing the iPhone X measurements beside common device groups highlights how it balances premium materials with familiar ergonomics. The table below provides a concise comparison to help gauge how the size and weight feel in everyday use.
| Device Group | Typical Display Size | Typical Width | Typical Weight | Context |
|---|---|---|---|---|
| iPhone X | 5.8 in | 70.9 mm | 174 g | Premium OLED, glass frame |
| Large compact phones (current) | 6.1–6.3 in | 73–75 mm | 170–190 g | Slightly larger, modern bezels |
| Older flagship (2018) | 6.5 in | 77 mm | 188–200 g | Bigger screen, often heavier |
| Compact flagship today | 5.3–5.4 in | 68–70 mm | 160–170 g | Smaller, lighter niche |
Build, Fit, and Long Term Use
Glass Back and Frame
The iPhone X’s glass back and stainless steel frame make it durable, but also slightly more slippery than matte plastic. Many users find that a case with a slim grip significantly improves handling, especially given the width near 71 mm.
Port Placement
With the Lightning port at the bottom center and no 3.5 mm headphone jack, the phone relies on either wired adapters or Bluetooth accessories. The physical profile remains slim, which helps keep dock and car mount compatibility straightforward.
Summary Takeaways
- Display: 5.8 inches with 2436 x 1125 resolution and ~458 ppi
- Body dimensions: 143.6 x 70.9 x 7.7 mm
- Weight: 174 grams (6.1 ounces)
