Key Size Takeaways for the Samsung Galaxy S8
The Samsung Galaxy S8 measures 148.9 mm tall, 68.1 mm wide, and 8 mm thick, with a 5.8‑inch display whose viewable area is larger thanks to minimal bezels. It weighs 155 g. This profile makes the phone tall and slender: easy to grip one‑handed vertically but slightly long for smaller pockets. Below are verified dimensions, display coverage, and how the S8 compares to common flagships and everyday use cases.
Physical Dimensions and Weight
Height, Width, and Thickness
In millimeters and inches, the S8’s chassis is tall and narrow, with a relatively slim profile for its screen size.
| Measure | Metric | Imperial | Source Notes |
|---|---|---|---|
| Height | 148.9 mm | 5.86 in | Manufacturer spec |
| Width | 68.1 mm | 2.68 in | Manufacturer spec |
| Thickness | 8 mm | 0.31 in | Manufacturer spec |
| Weight | 155 g | 5.47 oz | Manufacturer spec |
Display Size and Viewable Area
The device uses a 5.8‑inch diagonal Super AMOLED screen. Minimal top and bottom bezels increase the viewable area relative to traditional 5.8‑inch phones, and the ~18.5:9 aspect ratio adds vertical space for apps and media without significantly widening the chassis.
How the S8 Compares to Common Flagships
Placing the S8 beside widely used devices shows whether it feels more compact or more expansive in daily handling.
| Device | Height (mm) | Width (mm) | Thickness (mm) | Weight (g) | Display (in) |
|---|---|---|---|---|---|
| Galaxy S8 | 148.9 | 68.1 | 8 | 155 | 5.8 |
| iPhone 13 | 146.7 | 71.5 | 7.7 | 174 | 6.1 |
| Pixel 6 | 158.8 | 74.8 | 8.9 | 207 | 6.4 |
| OnePlus 9 | 163.6 | 73.8 | 197 | 6.55 |
Ergonomics and One‑Handed Use
- Tall, narrow chassis: easier to reach the top edge when held vertically with one hand compared with blocky phones of similar screen size.
- Thickness around 8 mm: comfortable for most grip styles; slightly protruding camera bump is common for the era.
- Weight at 155 g: moderate; noticeably heavier than very light older flagships but similar to contemporary devices.
Fit in Pockets and Bags
With a height of nearly 149 mm, the S8 approaches the upper range for single‑handed pocketability in jeans or small handbags. It will fit in most standard pockets, though very tight clothing pockets may feel snug. A case adds a few millimeters in each direction and increases thickness and weight, so plan accordingly if you use protective accessories.
Summary of Real‑World Size Impact
The Samsung Galaxy S8 is defined by a tall 5.8‑inch display in a chassis that is slim and relatively narrow, making it manageable for one‑handed vertical use but slightly lengthy for small pockets. Its weight is balanced for the class. Knowing the exact dimensions helps you judge pocket comfort, grip fatigue, and compatibility with cases and screen protectors.
