iPhone X measures 5.65 × 2.79 × 0.30 inches and 6.14 oz, with a 5.8-inch OLED screen in a compact frame.
The iPhone X landed in 2017 with a new shape for Apple phones. The bezels shrank, the Home button disappeared, and the screen stretched close to the edges. If you just want the figures, here they are again in one line: 5.65 inches tall, 2.79 inches wide, 0.30 inch thick, and 6.14 ounces in weight, with a 5.8-inch diagonal display measured as a rectangle. Those numbers come straight from Apple’s spec sheet.
How Big Is The iPhone X?
In physical terms, the iPhone X is a small phone by modern standards. Apple lists the height at 5.65 in (143.6 mm), the width at 2.79 in (70.9 mm), and the depth at 0.30 in (7.7 mm). The weight is 6.14 oz (174 g). The OLED screen spans 5.8 inches corner to corner when measured as a standard rectangle, and Apple adds that the viewable area is slightly less because the corners are rounded.
If you type “how big is the iphone x?” into a search bar, those four size numbers answer the question without guesswork. They fit many shirt pockets and most small crossbody bags, which is why the model still feels handy years later.
iPhone X Dimensions And Screen Size Explained
Quick context: phone screens are measured diagonally. Apple specifies the iPhone X panel at 5.8 inches when treated as a rectangle. Because the corners curve, the usable display is a touch smaller at the extreme edges, which is normal for modern edge-to-edge designs. You still get the same canvas in apps and videos that target the device.
Why the body feels small for a 5.8-inch phone: the iPhone X trimmed bezels around the screen, so the footprint stayed narrow even with a larger display than older 4.7-inch models. Hand feel comes from width more than height. At 2.79 inches wide, it lands in a sweet spot for one-hand taps and swipes for many people.
Ask again, “how big is the iphone x?” and think in pockets: the thickness is only 0.30 inch, so it slides past tight seams with little bulge. A lightweight case adds grip and 1–2 mm on each side, which still keeps the package smaller than many current phones.
How Big Is The iPhone X Compared To Other Models
Numbers make the story clear. Here’s a tight comparison against models shoppers still weigh up when thinking about size: the iPhone 8 (classic 4.7-inch body), the iPhone XS (the direct follow-up with the same footprint), and the iPhone XR (the larger value model from 2018). All figures below are straight from Apple’s technical pages.
| Model | Size (H × W × D, inches) | Weight |
|---|---|---|
| iPhone X (5.8″) | 5.65 × 2.79 × 0.30 | 6.14 oz |
| iPhone XS (5.8″) | 5.65 × 2.79 × 0.30 | 6.24 oz |
| iPhone XR (6.1″) | 5.94 × 2.98 × 0.33 | 6.84 oz |
| iPhone 8 (4.7″) | 5.45 × 2.65 × 0.29 | 5.22 oz |
Takeaway from the table: the iPhone XS kept the iPhone X footprint and added a few grams. The iPhone XR is taller, wider, and thicker. The iPhone 8 is shorter and a touch narrower but has thick bezels, so its screen is smaller even with a similar body width.
How Big Is The iPhone X In Daily Use
Pocket test: the 2.79-inch width and 0.30-inch depth make it comfortable in jeans, joggers, and most jacket pockets. If your current phone is a large 6.7-inch model, the iPhone X will feel much slimmer and shorter.
Grip and reach: the rounded edges and narrow frame let many users reach opposite corners with a thumb. If one-hand reach matters to you, the iPhone X lands near the upper limit before stretch gets tricky.
Screen comfort: the 5.8-inch OLED gives you a roomy keyboard and clear UI elements without forcing two-hand use at all times. Apps that target full-screen layouts use the extra vertical pixels well.
iPhone X Size Compared With Your Current Phone
Want a real-world feel before you buy or switch? Try these quick checks at home.
- Trace The Footprint — On a sheet of graph paper, draw a 5.65 × 2.79 inch rectangle. Round the corners slightly to mimic the device. Slide the paper into your pocket or bag and sit, stand, and walk.
- Stack Against Your Phone — Measure your current phone with a ruler. If it’s wider than 2.79 inches, the iPhone X will be easier to grip. If it’s taller than 5.65 inches, the iPhone X will tuck into pockets more cleanly.
- Case Check — Pick a slim case with minimal lip if pocket space is tight. If drop protection ranks higher for you, choose a tougher case and accept a few extra millimeters.
- Keyboard Trial — Open Notes on your current device and type with one hand for a minute. If your thumb strains on a 3.0-inch-plus width, the iPhone X’s 2.79-inch width should feel easier.
Who Should Choose This Size
Commuters and travelers: the smaller footprint sits well on tray tables and cramped armrests. The lighter weight reduces wrist fatigue during long reading or video sessions.
Parents and runners: it fits armband sleeves and small belt pouches that struggle with wider phones. The narrower width also helps one-hand texting while holding a bag or a coffee.
Small hands: if large devices feel unwieldy, the iPhone X keeps you in the modern all-screen world without bumping up to the broad frames seen on plus-size models.
Fit Tips, Cases, And Carry Options
Pick The Right Case — A thin TPU or clear shell adds grip with little bulk. Rugged cases add safety but can push the width near 3 inches. Choose based on pocket space and drop risk.
Add A Grip Aid — Rings and low-profile grips help with reach. Keep them centered to avoid wobble on tables.
Use A Slim Wallet — If you pair the phone with a wallet case, opt for a two-card insert to keep thickness down.
Plan For Accessories — If you dock your phone in a bike mount or gimbal, check the clamp range. The iPhone X’s height and width fall into most “small” mount brackets.
FAQ-Free Sizing Notes You Can Trust
Where the numbers come from: all measurements and weights in this guide link back to Apple’s technical pages for each model, published on Apple Support. The iPhone X page lists 5.65 × 2.79 × 0.30 inches and 6.14 oz, and confirms the 5.8-inch display measured as a rectangle with rounded corners reducing viewable area at the extreme edges.
Why the XS matches the footprint: Apple repeated the same height, width, and depth for iPhone XS, with a small bump in weight to 6.24 oz. If you swap between cases, check the camera cut-out, but the body size is the same.
How the XR compares: XR steps up in every direction—5.94 × 2.98 × 0.33 inches and 6.84 oz—so it fills a pocket more and offers a larger 6.1-inch LCD.
How the older 4.7-inch body feels: iPhone 8 at 5.45 × 2.65 × 0.29 inches and 5.22 oz is shorter and narrower, yet the screen is smaller because of thick top and bottom bezels.
