Samsung Galaxy S8 Plus size at a glance
The Samsung Galaxy S8 Plus measures 159.5 x 73.4 x 8.1 mm and weighs 173 g. It features a 6.2-inch display with 2960 x 1440 resolution and a relatively slim 8.1 mm profile. These figures make it taller and slightly heavier than many phones released after 2020, while its display-to-body ratio was class-leading at the time. Below you will find verified dimensions, how it fits in the hand, comparisons with newer devices, and practical guidance for cases, one-hand use, and pocketability.

What the dimensions mean in your hand
One-hand reach and grip comfort
With a 159.5 mm height, the S8 Plus is close to the practical limit for one-handed use on most adult hands. Many users find it manageable with a slight finger curl or hand posture adjustment, but it can be challenging for those with smaller hands. The 73.4 mm width fits comfortably across most palm widths, while the 8.1 mm thickness provides a slim, modern profile with minimal gap when holding the device.
Display-to-body ratio and bezel design
At launch, the S8 Plus emphasized an edge-to-edge 18.5:9 display with minimal bezels, giving a 6.2-inch panel a premium, immersive look. This high screen-to-body ratio was among the best in class for its time and makes the phone feel larger than its footprint suggests. Tall content such as articles and videos benefits from the elongated aspect ratio, though some users may notice slight cropping on apps not optimized for the 18.5:9 format.
Portability and pocketability
Fitting in pockets and bags
Thanks to its slim 8.1 mm depth, the S8 Plus can fit into many standard pockets where thicker phones would bulge noticeably. However, the tall 159.5 mm height means it often extends above the pocket opening on jeans or smaller trousers. A lightweight silicone case can reduce thickness slightly while improving grip; slimmer hybrid cases preserve most pocketability without adding bulk.
How it compares to newer phones
Size trends since 2017
Compared with phones released after 2020, the S8 Plus is noticeably taller and lighter. Many current flagships add height for larger cameras and batteries while sometimes keeping a narrow width to aid one-hand use. As a result, newer phones can feel narrower in the hand but may be longer when laid flat. The S8 Plus remains competitive for users who prefer a display above 6 inches without the extremes of today’s large slabs.
| Model | Height (mm) | Width (mm) | Depth (mm) | Weight (g) |
|---|---|---|---|---|
| Samsung Galaxy S8 Plus (2017) | 159.5 | 73.4 | 8.1 | 173 |
| Typical current flagship (example) | 162–165 | 74–78 | 8.5–9.2 | 200–210 |
Practical recommendations
Cases, screen protectors, and everyday use
- Choose slim cases (0.5–1.5 mm) to retain pocketability while adding grip and scratch protection.
- Tempered glass screen protectors are widely available and preserve touch responsiveness.
- If one-hand use is essential, consider reaching for a larger device only occasionally or use palm-swipe gestures to compensate for height.
- For pockets, slim silicone or nylon cases reduce bulk and lower the risk of snagging.
Common questions about the S8 Plus size
Will it fit in my pocket?
Yes, it will fit in most standard pants pockets, but the tall height may extend above the pocket opening on tighter fabrics. A slim case can help by reducing overall thickness slightly and improving grip.
Is it too big for one-hand use?
It is near the upper threshold for one-handed reach. Users with average or larger hands can typically reach the top, while those with smaller hands may prefer two-handed use or accessibility gestures.
How does it compare to modern flagships?
Modern flagships often increase height and weight while sometimes narrowing the chassis. The S8 Plus therefore feels shorter and lighter than many current devices, but its 6.2-inch display still provides a large, immersive experience by today’s standards.
