The iPhone 6 Plus measures 5.5 inches diagonally across a 3.06 by 5.44 inch face, with an overall height of 6.22 inches, width of 3.06 inches, and depth of 0.28 inch. The device was introduced in September 2014 and was among the first iPhones to feature a larger, edge-to-edge display and optical image stabilization on the rear camera. Below are the precise verified dimensions, key design notes, and practical comparisons to everyday objects so you can quickly understand how the iPhone 6 Plus fits in the hand and pocket.
Key Dimensions at a Glance
Display size is rounded to the nearest diagonal inch, while the physical chassis dimensions describe the full glass-and-metal frame.
| Metric | Inches | Millimeters | Source Type |

| Height (chassis) | 6.22 in | 158 mm | Verified (Apple spec sheet) |
| Width (chassis) | 3.06 in | 77.6 mm | Verified (Apple spec sheet) |
| Depth (chassis) | 0.28 in | 7.1 mm | Verified (Apple spec sheet) |
| Weight | 172 g (6.06 oz) | 172 g | Verified (Apple spec sheet) |
Display vs Chassis: What Changes and Why It Matters
The 5.5-inch measurement refers to the visible diagonal of the LCD panel, not the glass bezel. Because the display has rounded corners, actual viewable area is slightly smaller, and software may reserve a small portion for the interface. The chassis dimensions above include the glass frame, antennas, and rear camera bump, so the phone will feel slightly larger than the display alone suggests. The 0.28-inch depth is modest, but when paired with the larger body, pocket fit depends more on width and your pocket shape than on thickness alone.
Size in Context: Practical Comparisons
Placing specs beside familiar objects makes the scale clearer at a glance.
- Height roughly matches a standard credit card (3.37 by 2.12 in) when stood vertically on its short edge.
- Width is slightly wider than a U.S. dollar bill (6.14 by 2.61 in).
- Depth is comparable to a No. 2 pencil or a stack of about three U.S. quarter coins.
- Weight is similar to a can of soup or a large apple.
Design Evolution and User Experience
The iPhone 6 Plus helped popularize larger displays in Apple’s lineup, moving from the 4-inch designs of earlier models to a 5.5-inch panel optimized for browsing, reading, and media. The slightly larger body changes how the phone fits one-handed use, pocketability, and case selection. Rounded corners and a metal frame were central to the industrial design language introduced with this generation and carried forward into later models.
Handling, Cases, and Everyday Fit
Because the width is close to three inches, users with smaller hands may notice a less comfortable reach across the screen. Many opt for a case that reduces overall width for better pocket fit or choose models with a slim form factor. Cases that add bulk can noticeably increase width, so it’s worth measuring your pocket or bag space before committing to a heavy protector. The overall depth is slim, which helps the phone sit flush in many standard-depth pockets.
Comparison to Predecessor and Contemporaries
Compared with the iPhone 5s (4-inch display), the iPhone 6 Plus is notably taller and wider, making the jump in one-handed use more pronounced. Against key competitors at the time, the 5.5-inch display sat in the middle of the market—not the largest, but larger than many flagship options from the same year. For perspective on modern devices, today’s standard flagships are often wider and deeper, but the 2014-era chassis remains a useful reference point for understanding how larger iPhones have evolved.
