Dimensions for iPhone 6: specs and repair guide
TL;DR:
- The iPhone 6 measures 138.1 mm in height, 67.0 mm in width, and 6.9 mm in depth, weighing 129 grams. Its compact, curved aluminium design affects repair procedures, accessory compatibility, and internal component interchangeability. Precise dimensions are essential for sourcing correct parts, ensuring proper fit, and avoiding damage during repairs.
The iPhone 6 measures 138.1 mm in height, 67.0 mm in width, and 6.9 mm in depth, with an official weight of 129 grams. That translates to 5.44 x 2.64 x 0.27 inches for anyone working from imperial measurements. Apple built the device around a 4.7-inch Retina display and a single-piece aluminium chassis, and those choices define every dimension you will encounter when sourcing parts or fitting accessories. Whether you are planning a screen replacement, ordering a new battery, or checking case compatibility, knowing the exact iPhone 6 size specifications is the starting point.
What are the exact dimensions for iPhone 6?
The official dimensions of the iPhone 6 are 138.1 mm tall, 67.0 mm wide, and 6.9 mm deep. In inches, that is 5.44 x 2.64 x 0.27. These figures apply to all colour variants: Space Grey, Silver, and Gold. The weight of 129 grams (4.55 oz) is consistent regardless of colour, which matters when you are calculating shipping or comparing handheld feel across models.
| Specification | Metric | Imperial |
|---|---|---|
| Height | 138.1 mm | 5.44 in |
| Width | 67.0 mm | 2.64 in |
| Depth | 6.9 mm | 0.27 in |
| Weight | 129 g | 4.55 oz |
| Display size | 4.7 in | 4.7 in |
The 4.7-inch display sits within a body that carries a screen-to-body ratio of approximately 65.8%. By 2026 standards that ratio looks modest, but in 2014 it was competitive. The large bezels above and below the screen are what push the total height to 138.1 mm despite the relatively compact display. For repair work, those bezels also mean more frame real estate to manage during disassembly.
Key facts to keep in hand when ordering parts:
- Height: 138.1 mm (5.44 in)
- Width: 67.0 mm (2.64 in)
- Depth: 6.9 mm (0.27 in)
- Weight: 129 g (4.55 oz)
- Display: 4.7 inches, IPS LCD
How do iPhone 6 dimensions compare with other iPhone models?
The iPhone 6 and iPhone 6 Plus share the same design language but differ significantly in size. The iPhone 6 Plus measures 158.1 x 77.8 x 7.1 mm and weighs 172 grams, making it 20 mm taller, 10.8 mm wider, and 43 grams heavier than the standard model. That difference is large enough to affect one-handed use entirely, and it means no accessories or external parts cross over between the two.
| Model | Height | Width | Depth | Weight |
|---|---|---|---|---|
| iPhone 6 | 138.1 mm | 67.0 mm | 6.9 mm | 129 g |
| iPhone 6 Plus | 158.1 mm | 77.8 mm | 7.1 mm | 172 g |
| iPhone 6s | 138.3 mm | 67.1 mm | 7.1 mm | 143 g |
The iPhone 6s is where things get deceptive. Its external dimensions are almost identical to the iPhone 6, with just 0.2 mm added in height and width, and 0.2 mm extra depth. Holding both devices, you would struggle to tell them apart. However, iPhone 6 and 6s screens and batteries are not interchangeable due to internal connector layout differences and manufacturing tolerances. This catches out a lot of DIY repairers who assume that near-identical casing means compatible internals.
Small changes in phone size between the iPhone 6 and Plus models also have a knock-on effect for accessory choice. A case designed for the 6 will not fit the 6 Plus, and vice versa. If you are buying a replacement back cover or a protective frame, always confirm the model number before ordering.
What design features influence the iPhone 6’s size and shape?
Apple constructed the iPhone 6 around a 6000-series aluminium chassis with curved edges running along the full perimeter of the device. That single-piece construction is what allows the 6.9 mm depth, which was genuinely market-leading when the phone launched in 2014. The aluminium is machined to tight tolerances, and the curved profile is not cosmetic. It is structural, distributing stress across the frame rather than concentrating it at sharp corners.
The trade-off is that curved aluminium edges make the iPhone 6 more prone to dents and frame damage. A drop that would leave a flat-edged phone with a scuff can deform the iPhone 6 frame enough to prevent a replacement screen from seating correctly. This is not a minor inconvenience during repairs. A bent frame will cause the digitiser to register phantom touches or fail to respond at the edges, even with a brand-new screen fitted.
The slim profile also creates challenges with screen protectors. Flat tempered glass protectors often do not fully adhere to the iPhone 6 screen because the glass curves slightly at the edges. A protector that looks perfectly fitted in the centre will lift at the corners within days. For this reason, flexible TPU film protectors or edge-to-edge tempered glass cut specifically for the iPhone 6 are the more reliable choice.
Pro Tip: When fitting a screen protector to an iPhone 6, clean the edges with isopropyl alcohol and use a UV-cure adhesive protector if you want a permanent bond. Standard dry-fit tempered glass will lift at the corners due to the curved aluminium frame.
How do iPhone 6 dimensions affect DIY repairs?
The compact internal layout of the iPhone 6 is a direct consequence of its slim 6.9 mm depth. Every component sits in a tightly packed arrangement, and there is very little clearance between the battery, logic board, and display assembly. This is what makes iPhone 6 repairs more demanding than the dimensions suggest.
Follow this sequence when approaching a DIY repair:
- Confirm your model number first. Check Settings > General > About or look for the model identifier on the SIM tray. Ordering parts for an iPhone 6s by mistake is a common and costly error.
- Use the correct pentalobe screwdriver. The two screws flanking the Lightning port are 0.8 mm pentalobe. A standard Phillips will strip them immediately.
- Release the display at the bottom edge only. The iPhone 6 screen lifts from the bottom and hinges upward from the top. Opening from the wrong edge risks tearing the display cables.
- Disconnect the battery before touching any other connector. The battery connector sits close to the display connectors, and accidental contact can short the logic board.
- Handle the home button cable with extreme care. The home button cable is fragile and directly linked to Touch ID. Damage here causes permanent Touch ID failure that cannot be resolved by software.
The fifth point deserves emphasis. Touch ID on the iPhone 6 is paired to the logic board at the factory. If the home button cable tears, or if you fit a third-party home button, Touch ID will stop working permanently. The fingerprint sensor itself cannot be replaced independently. This is not a limitation of the part quality. It is a hardware-level security pairing that Apple built into the device.
Pro Tip: Before ordering any replacement screen, battery, or charging port for an iPhone 6, cross-reference the part number against your specific model. The A1549, A1586, and A1589 variants of the iPhone 6 share the same external dimensions but may have minor internal differences depending on the regional market.

What should you know about accessory compatibility?
Accessory manufacturers design cases and covers around the published iPhone 6 measurements of 138.1 x 67.0 x 6.9 mm, but the curved edges mean that fit varies more than the numbers suggest. A case that fits perfectly on a flat-backed phone can feel loose or misaligned on the iPhone 6 because the curvature affects how the device sits within the case walls.
Points to check before buying any iPhone 6 accessory:
- Confirm the case is labelled specifically for iPhone 6, not iPhone 6s. The 0.2 mm size difference is enough to cause a loose fit or prevent the volume buttons from aligning.
- Check button cutout positions. The sleep/wake button moved from the top of the device (iPhone 5s) to the right side on the iPhone 6. Cases designed for earlier models will not have the correct cutout placement.
- Dock and holster fit depends on depth. At 6.9 mm, the iPhone 6 is thinner than most of its contemporaries. A holster designed for a thicker phone will not hold the device securely.
- Screen protector type matters. As noted above, flat tempered glass lifts at the edges. Look for protectors marketed as “full coverage” or “edge-to-edge” with a curved edge cut.
Keeping up with accessory trends for 2025 shows that MagSafe-style magnetic cases are now being retrofitted for older iPhone models, including the iPhone 6. These require precise internal magnet placement relative to the device dimensions, so always verify compatibility before purchasing.

Why dimensions matter more than most repair guides admit
I have handled a lot of iPhone 6 units over the years, and the dimension question comes up in two situations: before a repair, when someone is ordering parts, and after a repair, when something does not fit quite right. The second situation is almost always caused by skipping the first step properly.
The near-identical external size of the iPhone 6 and 6s is genuinely misleading. I have seen experienced technicians order 6s screens for a 6 repair because the measurements looked close enough. They are not interchangeable, and the wasted time and money is entirely avoidable if you verify the model number before placing an order.
What I find underappreciated is the frame damage issue. The curved aluminium on the iPhone 6 looks elegant, but a device that has been dropped even once may have a subtly bent frame that you cannot see with the naked eye. When that happens, a new screen will not seat flush, and the repair looks botched even though the part is fine. I always check frame straightness with a flat surface before ordering a replacement display. It takes ten seconds and saves a lot of frustration.
The 6.9 mm depth also means there is almost no margin for error when routing cables during reassembly. If a cable is not seated exactly as it was from the factory, the back cover will not close flush. That slight bulge at the edge is a sign of a misrouted cable, not a wrong-sized part. Knowing the device’s depth helps you understand why precision matters at every step.
