It feels like a lifetime ago. Back in 2014, if you walked into an Apple Store, the biggest phone you could get was a 4-inch iPhone 5s. Then the iPhone 6 happened. It was a massive pivot. People were genuinely stressed about whether the size of an iPhone 6 would actually fit in a normal pocket or if they’d need to start wearing cargo pants again.
The iPhone 6 wasn't just another update; it was a total admission by Apple that Samsung was right about big screens. Steve Jobs famously hated large phones, once saying no one would buy them. He was wrong. The market shifted, and the iPhone 6 became the vessel for that change. It brought us the 4.7-inch display, a spec that Apple clung to for nearly a decade through various SE models.
Honestly, it’s the most influential chassis Apple ever designed.
The cold, hard numbers on iPhone 6 size
Let’s talk dimensions because that's why you're here. The iPhone 6 measures exactly 5.44 inches (138.1 mm) in height and 2.64 inches (67.0 mm) in width. It’s incredibly thin—just 0.27 inches (6.9 mm). If you hold one today, it feels like a wafer. It’s light, too, weighing in at 4.55 ounces (129 grams). Compare that to a modern iPhone 15 Pro, which feels like a lead brick by comparison, and you realize how much "hand feel" we've sacrificed for battery life and cameras.
The screen itself is a 4.7-inch (diagonal) LED-backlit widescreen. This gave us a resolution of 1334-by-750 pixels. By 2026 standards, that sounds pathetic. We have watches with better density now. But in 2014? It was the "Retina HD" revolution. It had a 1400:1 contrast ratio and was the first time we saw those dual-domain pixels for wider viewing angles.
It’s easy to forget how rounded it was. After years of the flat, industrial edges of the iPhone 4 and 5, the iPhone 6 went all-in on curves. The glass flowed into the aluminum. It felt like a smooth pebble. This design choice actually made the size of an iPhone 6 feel smaller than it actually was.
Why the 4.7-inch screen was the "Sweet Spot"
For a long time, the tech world was split. You had the "mini" enthusiasts and the "phablet" lovers. Apple tried to hit the middle. The 4.7-inch screen was designed to be usable with one hand. They even added "Reachability"—that weird feature where you double-tap the home button to slide the top of the screen down.
Remember that? It was a literal software band-aid for the fact that screens were getting too big for human thumbs.

The Bendgate controversy: When thinness went too far
You can't discuss the iPhone 6 physical footprint without mentioning the structural drama. Because the phone was so thin and used 6000-series aluminum, it had a weak point near the volume buttons.
Lewis Hilsenteger from Unbox Therapy basically broke the internet when he bent one with his bare hands.
It wasn't just a meme. It was a physics problem. The size of an iPhone 6 combined with its slim profile meant that if you sat down with the phone in a tight pair of jeans, the chassis could actually warp. Apple eventually quieted the noise by claiming only nine customers complained, but they secretly reinforced the frame in later production batches and switched to 7000-series aluminum for the 6s.
Real-world comparisons to modern devices
If you’re trying to visualize how big this phone is compared to what’s in your pocket right now, think about the iPhone SE (2022). They are virtually identical in footprint.
- iPhone 13/14/15/16 Pro: These feel gargantuan next to a 6. They are thicker, heavier, and much wider.
- iPhone 13 Mini: Surprisingly, the Mini is actually smaller than the iPhone 6 in total height and width, despite having a larger 5.4-inch screen. That’s the power of losing the "forehead and chin" bezels.
The iPhone 6 had huge chunks of unused space at the top and bottom. The home button alone took up a massive amount of real estate. When we look at the size of an iPhone 6 today, we see a lot of wasted potential.
Ergonomics and the death of the one-handed phone
Using an iPhone 6 in 2026 is a trip. It’s so light it almost feels fake. Most people today are used to phones that weigh 180 to 220 grams. Dropping down to 129 grams feels like holding a piece of cardboard.
But there was a downside to that size. The battery was tiny. Because Apple obsessed over making the iPhone 6 thin (6.9mm), they could only fit an 1,810 mAh battery inside. For context, modern phones usually pack 3,500 to 5,000 mAh. The iPhone 6 was notorious for dying by 4:00 PM.
The move to the 4.7-inch size also forced Apple to move the power button. On the iPhone 5s, it was on top. On the 6, it moved to the right side. This change was permanent. If the button had stayed on top, you wouldn't have been able to reach it without shifting your entire grip.
How to use these dimensions for accessories or DIY
If you've found an old iPhone 6 in a drawer and want to repurpose it—maybe as a dedicated music player or a dashcam—you need to be careful with cases.
While the iPhone 6 and 6s look identical, the 6s is actually 0.2mm thicker. Most "hard" cases for a 6 won't fit a 6s perfectly. However, the iPhone 7 and 8 have almost the same dimensions, but the camera bump is significantly larger and moved slightly. You cannot reliably swap cases between an iPhone 6 and an iPhone 7.
The legacy of the 4.7-inch form factor
We really can't overstate how much this specific size defined a generation of users. It was the bridge between the "phone as a tool" era and the "phone as a media consumption device" era.

When people search for the size of an iPhone 6, they're often looking for a sense of nostalgia or trying to find a device that doesn't hurt their hands. There’s a segment of the population that still hates the "Max" and "Ultra" trend. They miss when a phone was a 4.7-inch slab that disappeared in a pocket.
It’s worth noting that the iPhone 6 Plus launched alongside it, introducing the 5.5-inch size. That was the "big" one. But the standard 6 was the one that sold in the hundreds of millions. It was the "just right" size for the average person in 2014, and it set the template for the next four years of Apple design.
Practical steps for iPhone 6 owners today
If you are dealing with an iPhone 6 right now, keep these physical realities in mind:
- Check for frame warping: Lay the phone face down on a flat glass table. If it wobbles, the frame is bent. This can eventually cause the screen to "pop" out or lead to "Touch Disease," where the touch controller chips desolder from the logic board.
- Battery Swaps: Because the phone is so thin, the battery is very close to the screen assembly. If the battery begins to swell (due to age), it will immediately start pushing against the LCD, causing white spots or discoloration. If you see this, stop using it immediately.
- Modern Utility: Even though it’s physically small and pocketable, the iPhone 6 is capped at iOS 12. Most modern apps won't run. It’s best used as an offline GPS, a basic iPod, or a distraction-free writing tool.
The size of an iPhone 6 remains a benchmark in industrial design. It was the moment Apple stopped trying to dictate how we held our phones and started listening to the demand for more screen real estate. It wasn't perfect—it was fragile and the battery was weak—but it defined the modern smartphone silhouette we still use today.
