The iPhone 7 and iPhone 8 share nearly identical dimensions, with only subtle differences in weight and build materials.
Physical Dimensions: Comparing iPhone 7 and iPhone 8
The question “Are iPhone 7 And 8 The Same Size?” often arises because Apple maintained a very similar design language between these two models. Both phones have a familiar look, featuring a 4.7-inch Retina HD display and a home button with Touch ID. However, the devil is in the details.
The iPhone 7 measures exactly 138.3 mm in height, 67.1 mm in width, and has a thickness of 7.1 mm. The iPhone 8 matches these height and width measurements almost perfectly but is slightly thicker at 7.3 mm due to its glass back design, which replaced the aluminum back found on the iPhone 7.
This slight increase in thickness contributes to a marginally heavier device. The iPhone 7 weighs about 138 grams, while the iPhone 8 tips the scales at around 148 grams. This difference is subtle but noticeable when holding both phones side by side.
Material Differences Affecting Size Perception
While both phones have nearly identical dimensions, their materials give different tactile experiences. The iPhone 7 uses an aluminum body that feels lightweight and matte to the touch. In contrast, the iPhone 8 sports a glass back that not only adds weight but also gives it a glossier, more premium feel.
This glass back was introduced to enable wireless charging capabilities on the iPhone 8, which was absent on the iPhone 7. So while you might not see much difference in size on paper, the overall feel and grip can differ due to these material changes.
Display Size and Screen Design: Identical or Not?
Both devices feature a Retina HD display measuring exactly 4.7 inches diagonally with a resolution of 1334 x 750 pixels at 326 pixels per inch (ppi). The screen-to-body ratio remains almost unchanged between models since Apple retained the same bezels and front design.
In terms of screen technology, though, there are minor improvements on the iPhone 8 such as True Tone display support which adjusts color temperature based on ambient lighting for a more natural viewing experience. But this doesn’t affect physical size – just visual quality.
So yes, if you’re wondering “Are iPhone 7 And 8 The Same Size?” from a display perspective, they absolutely are indistinguishable in size.
Button Placement and Port Compatibility
Apple kept all physical button placements consistent between these two models: volume buttons on the left edge, mute switch above them, power button on the right edge, and Lightning port at the bottom center flanked by stereo speakers.
This consistency means accessories like cases or docks designed for one model generally fit the other without issue—though slight variations in thickness may cause some tight fits or loose cases depending on brand precision.
Detailed Dimension Comparison Table
| Specification | iPhone 7 | iPhone 8 |
|---|---|---|
| Height (mm) | 138.3 | 138.4 |
| Width (mm) | 67.1 | 67.3 |
| Thickness (mm) | 7.1 | 7.3 |
| Weight (grams) | 138 | 148 |
| Material Body | Aluminum (7000 series) | Glass front & back with aluminum frame |
| Screen Size (inches) | 4.7 Retina HD Display | 4.7 Retina HD Display with True Tone |
| Wireless Charging Support | No | Yes (Qi standard) |
The Impact of Weight and Thickness Differences in Daily Use
The extra weight of about ten grams on the iPhone 8 might seem trivial but can be felt during extended use or when carrying it around all day in your pocket or bag.
Similarly, that extra two-tenths of a millimeter thickness doesn’t sound like much but can influence how snugly your phone fits into slim cases or holders designed specifically for one model.
For users upgrading from an older device or switching between these two models regularly, these differences could affect comfort levels slightly—especially if you prefer ultra-thin phone profiles.
Casing and Protection Considerations Between Models
Since “Are iPhone 7 And 8 The Same Size?” is often asked by people looking to buy accessories like cases or screen protectors, it’s important to note that while many cases fit both phones interchangeably due to near-identical sizing, some precision-fit cases might not accommodate the thicker glass back of the iPhone 8 perfectly.
Screen protectors remain fully compatible since front dimensions did not change at all.
If you want guaranteed perfect fitment without any risk of looseness or pressure points on buttons or camera cutouts, buying model-specific accessories is advisable despite their close similarity.
Cameras: Does Size Affect Functionality?
While camera hardware size isn’t directly tied to overall phone dimensions here, it’s worth noting that both phones feature single-lens rear cameras with similar specs: a 12MP sensor with optical image stabilization.
The physical camera bump dimension remains consistent across both models despite minor changes in internal hardware performance enhancements on the iPhone 8’s image signal processor.
So no size difference impacts camera usability or accessory compatibility like lens protectors or mounts designed for these models.
The Battery Capacity Factor Relative to Phone Size
Another subtle outcome of slight dimensional changes lies under the hood—battery capacity.
The iPhone 7 packs a battery rated at approximately 1960 mAh while the iPhone 8’s battery capacity slightly reduces to around 1821 mAh despite its thicker body due to space taken up by wireless charging components inside its glass back design.
This reduction didn’t translate into worse battery life thanks to efficiency improvements from Apple’s A11 Bionic chip powering the iPhone 8 compared to A10 Fusion chip inside the iPhone 7.
Still, this detail highlights how small shifts in internal layout tied to physical dimensions can influence component choices Apple makes between generations—even when external sizes look nearly identical.
Aesthetic Differences That Influence Perceived Size
People often confuse aesthetic changes for size differences when comparing these two models side by side:
- Color options: The glossy glass finish of the iPhone 8 reflects light differently than matte aluminum of the iPhone7.
- Back design: The seamless glass back looks visually thinner yet actually adds thickness.
- Weight distribution: Heavier glass shifts balance subtly compared to lighter aluminum chassis.
- Fingerprint magnet: The glass surface attracts fingerprints more readily than aluminum affecting grip feel rather than actual size but influencing user perception nonetheless.
These factors combine so users might say “the phone feels bigger” even though measured dimensions show minimal change—proving perception isn’t always reality when it comes to device sizing nuances.
