iPhone X Dimensions: Height, Width, Depth & Weight
Apple lists the iPhone X at 5.65 inches (143.6 mm) high, 2.79 inches (70.9 mm) wide and 0.30 inch (7.7 mm) deep, with a weight of 6.14 ounces (174 grams). Here is the same data in one place:
| Measurement | Inches | Millimeters | Centimeters |
|---|---|---|---|
| Height | 5.65 in | 143.6 mm | 14.36 cm |
| Width | 2.79 in | 70.9 mm | 7.09 cm |
| Depth (thickness) | 0.30 in | 7.7 mm | 0.77 cm |
| Weight | 6.14 oz | 174 g | – |
Some sites list 174.1 g, which is the same phone. Apple notes that size and weight can vary a little by configuration and manufacturing.
Every version shares one body size. That includes the 64GB and 256GB storage options and the Model A1865, A1901 and A1902 variants. Only the modem and network bands change.
The frame is surgical-grade stainless steel, with glass on the front and back. The phone is rated IP67 for splash, water and dust resistance.

iPhone X Screen Size & Display Specs
Apple markets a 5.8-inch display. Measured as a plain rectangle, the screen is about 5.85 inches diagonally. The real viewable area is a bit smaller because of the rounded corners and the notch.
Key iPhone X display specs:
- Panel: Super Retina HD OLED
- Resolution: 2436 × 1125 pixels at 458 ppi
- Aspect ratio: 19.5:9
- Contrast ratio: 1,000,000:1
- Peak typical brightness: 625 nits
- Extras: True Tone, wide color (P3), HDR and 3D Touch
The big win is the all-screen design. Wikipedia notes it was the first iPhone with no home button and the first with an OLED screen. Apple fit a screen larger than the iPhone 8 Plus’s 5.5 inches into a body close to the iPhone 8’s size. The 8 Plus is 158.4 mm tall, and the X is 14.8 mm shorter.
iPhone X Size in Real Life: Fit, Cases & One-Handed Use
On paper, 70.9 mm is slim. In the hand, that narrow width is why the phone is easy to grip and slips into a pocket without fuss.
Is the iPhone X easy to use with one hand? Reaching the top corners is the weak spot. Swiping down for Control Center and notifications is hard for small hands. Use Reachability in Settings to pull the screen down.
Do iPhone XS cases fit the iPhone X? Yes, in practice. The iPhone XS has the same 143.6 × 70.9 × 7.7 mm body. Search for “iPhone X/XS case” and “iPhone X/XS screen protector.” Always check the listing for both models.
Buying used in the US? Keep three things in mind:
- The Face ID range is limited. It works best at about 25–50 cm from your face, according to a review cited on Wikipedia.
- The X supports up to iOS 16. It can’t run iOS 17 or later.
- Check battery health before you pay. Batteries age.
iPhone X vs iPhone 17 & Other iPhone Sizes
The iPhone 17 dimensions are 149.6 × 71.5 × 8 mm, with a weight of 177 g and a 6.3-inch screen. Apple’s own page confirms the 6.3-inch display and 177 g weight.
Here is how the iPhone X size compares:
| Model | Height × Width × Depth | Weight | Screen |
|---|---|---|---|
| iPhone 8 | 138.4 × 67.3 × 7.3 mm | 148 g | 4.7 in |
