How tall is the iPhone X: exact height and key dimensions
The iPhone X stands 143.6 millimeters (5.65 inches) tall from top to bottom when measured across the face and outer glass edges. Apple lists this as the device height in official specifications. Width is 70.9 millimeters (2.79 inches), and thickness is 7.7 millimeters (0.30 inches). The chassis height includes the display and frame but not the camera bump, which sits slightly higher than the glass plane. Weight is listed at 174 grams (6.14 ounces). This iPhone was released in October 2017 with a 5.8-inch Super Retina OLED display and introduced Face ID, dual‑nano SIM and removal of the home button.
Display size versus body height: understanding the difference
Display size is measured diagonally across the screen, not linearly in height. The iPhone X display is 5.8 inches diagonally, but the taller physical dimension is about 143.6 mm because of the aspect ratio and minimal bezels. The display viewable area is slightly less than the outer glass due to the front camera and sensor area at the top. On larger successors, display size and body height often grow together, but the relationship between the two is driven by aspect ratio, not just screen area.
Display metrics that affect perceived height
- Aspect ratio: The iPhone X uses roughly 19.5:9, making it taller than older 16:9 phones with similar widths.
- Bezels: Smaller top and side bezels increase viewable area without proportionally increasing overall body size.
- Camera bump: Adds height when placed flat on a surface, but does not change the glass plane measurement used for listed device height.
Height in practical use: fit, pockets, and cases
At 143.6 mm tall, the iPhone X suits one-handed use for many people but can be challenging for those with smaller hands. Case designs often add 1 to 3 millimeters in each direction and may increase overall height slightly depending on bumpers or lip thickness. Pocket fit depends on jeans or coat pocket dimensions; the device’s relatively tall profile can catch on tight seams, so a slim case may improve comfort without significant bulk. When assessing whether the phone fits your lifestyle, consider total height with a typical case and your usual carrying method.
How the iPhone X height compares to modern iPhones
Compared with the iPhone 12 and 14, which are both 146.7 mm tall, the iPhone X is about 3 millimeters shorter. However, differences in camera bump height, button placement, and screen layout can make handling perceptions vary. The iPhone 12 and 14 also use a slightly narrower width and are slightly thicker, which can affect pocket fit. For users deciding between an iPhone X and newer models, overall hand feel and one-handed reach are often more meaningful than a few millimeters of height difference.
Camera bump and top sensor area: how they affect usable height
The camera bump on the iPhone X rises above the glass plane, typically adding a small amount of vertical thickness when the phone is placed on a flat surface. The top bezel houses the front-facing camera, proximity sensors and infrared components for Face ID, which reduces the viewable display area in that region. While bump height does not change the listed device height, it influences whether the phone lies flat and how cases or screen protectors must accommodate the camera.
When precise height matters: use cases and real-world fit
Knowing the iPhone X dimensions is important for selecting cases, screen protectors, car mounts and wallets. Most case manufacturers reference the 143.6 mm height in their listings, and they usually include additional millimeters for buttons and ports. If you plan to use a wallet or cardholder, the phone’s tall, narrow profile may fit better in vertical slots than smaller phones. For photography or media consumption, the height and 5.8-inch OLED panel create a near‑cinematic experience without making the chassis unwieldy for most adult hands.
Reliable sources and how Apple lists device dimensions
Apple’s official specifications pages list the iPhone X height as 143.6 mm (5.65 in) and width as 70.9 mm (2.79 in), with a thickness of 7.7 mm (0.30 in). Retailers and regulatory filings (such as FCC and CE documents) typically mirror these values. Measurements may vary by a few hundredths of a millimeter across sources due to rounding, but the official spec sheet is the most authoritative reference for end‑user dimensions.
