Key size specifications at a glance
The iPhone 8 Plus is a larger-screened variant of Apple’s 2017 iPhone 8 lineup. Below are the verified dimensional and weight specifications commonly referenced for device fit, case selection, and comparisons.
| Metric | iPhone 8 Plus | Notes / Reference |
|---|---|---|
| Height | 158.4 mm (6.24 in) | Vertical edge to edge |
| Width | 78.1 mm (3.07 in) | Horizontal edge to edge |
| Depth | 7.3 mm (0.29 in) | Thickness when not including camera protrusion |
| Weight | 202 g (7.12 oz) | Device only; varies slightly with cases and accessories |
| Screen size | 5.5-inch (diagonal) | Measured corner to corner of viewable area |
Manufacturers may round values; consider measuring your specific device or unit if exact tolerances are critical for fitment or compliance purposes.
Physical profile and how it compares
With a 5.5-inch display in a relatively compact chassis for its class, the iPhone 8 Plus is designed to balance screen area and one-handed reach. Its height of 158.4 mm places it between smaller phones and larger phablets, while the 78.1 mm width may still require two-handed use for many users. At 7.3 mm thick and 202 g, it remains noticeably slim and lightweight compared to many later devices with larger batteries and glass stacks. These measurements inform case compatibility, pocketability, and accessory decisions.
Fit, compatibility, and everyday considerations
Case and screen protector selection
Because dimensions determine fit, always reference manufacturer specifications when choosing accessories. Common cutout requirements include:
- Precise height and width within a few millimeters for tight cases.
- Camera cutout depth to avoid interference with raised lenses.
- Port and button placement for unobstructed access.
Small deviations can affect camera alignment, wireless charging alignment, and overall grip comfort.
Pocketability and handling
The 78.1 mm width is near the upper range of single-hand comfort for many adults, and the 158.4 mm height can make one-handed use challenging. A slim profile helps, but grip styles, hand size, and use scenarios should guide case and handling choices. If portability is a priority, consider how the device fits in common storage locations.
Contextualizing the measurements
Understanding iPhone 8 Plus measurements is most useful when tied to real-world use. Compare these numbers with devices you currently use to anticipate changes in feel and behavior. Cases, screen protectors, and even swollen batteries can alter the effective dimensions over time, so re-measure or reassess fit when replacing major components.
Frequently asked questions about size
- Is the iPhone 8 Plus taller than the iPhone 8? No; both share the same height at 158.4 mm.
- Does the iPhone 8 Plus fit in standard jeans pockets? Many users find it fits, but tightness varies by pocket style and personal comfort.
- Are iPhone 8 Plus and iPhone X cases interchangeable? Generally not, due to differences in camera layout, sensors, and component placement.
- How does the weight compare to modern iPhones? The iPhone 8 Plus is typically lighter than current iPhone models with larger batteries and glass builds.
When to verify measurements
If you are using the device for compliance, repair, or custom enclosure work, verify against the specific unit and current manufacturer documentation. Environmental factors such as case thickness, screen protector bezel width, and battery health can shift practical dimensions slightly from the nominal values above.
