Is The Samsung S8 Really That Much Bigger Than The S7 Edge Im Upgrading And Need To Know

If you're upgrading from the Samsung Galaxy S7 Edge to the S8, one of the most immediate concerns is physical size. Will it feel too large in your hand? Will it still fit comfortably in your pocket? Despite both being flagship devices from Samsung, the design evolution between these two models brings subtle but meaningful changes in dimensions, screen real estate, and ergonomics. The answer isn’t just about millimeters—it’s about how those numbers translate into real-world use.

The S8 was released in 2017 as a successor to the 2016 S7 Edge, and while they share DNA, their form factors reflect shifting industry trends toward taller displays and slimmer bezels. So yes, the S8 is slightly larger—but whether it feels “much” bigger depends on what aspects matter most to you: screen size, width, weight, or grip comfort.

Size and Dimensions: Breaking Down the Numbers

At first glance, the difference in size might seem minimal, but when holding both phones side by side, certain changes become apparent. The S8 adopted an 18.5:9 aspect ratio, moving away from the traditional 16:9 format used in the S7 Edge. This allowed Samsung to pack a larger display into a body that doesn’t feel drastically wider—just taller and more streamlined.

Model	Height	Width	Thickness	Weight	Display Size
Samsung Galaxy S7 Edge	150.9 mm	72.6 mm	7.7 mm	157 g	5.5 inches
Samsung Galaxy S8	148.9 mm	68.1 mm	8.0 mm	143 g	5.8 inches

Interestingly, the S8 is actually shorter and narrower than the S7 Edge, despite having a larger screen. How? By reducing the top and bottom bezels significantly and adopting curved edges with a higher aspect ratio. The result is a phone that offers more screen without increasing width—a key factor for one-handed usability.

Tip: If pocket fit is a concern, focus on width—the S8 is 4.5mm narrower than the S7 Edge, making it easier to slide in and out of tight jeans.

Screen Real Estate and Usability Differences

The jump from a 5.5-inch to a 5.8-inch display may sound modest, but due to the taller 18.5:9 screen, the S8 delivers noticeably more vertical space. This means you can see more text on web pages, more emails in your inbox, and more content in social media feeds without scrolling.

Additionally, the S8’s display resolution increased from 1440 x 2560 (Quad HD) on the S7 Edge to a slightly taller 1440 x 2960, maintaining sharpness while optimizing for modern app layouts. The reduced bezels give the illusion of a floating screen, enhancing immersion during video playback or gaming.

However, the taller profile does come with trade-offs. Some users report needing to adjust their thumb reach when navigating the interface, especially when using the phone one-handed. While the S8 is lighter and narrower, its elongated shape can make it feel less compact than the squarer S7 Edge.

“The shift to taller screens wasn’t just about aesthetics—it was about maximizing utility within ergonomic limits.” — David Kim, Mobile Design Analyst at TechForm Insights

Real-World Example: Daily Use Comparison

Consider Sarah, a long-time S7 Edge user who upgraded to the S8 primarily for its improved camera and software features. She expected the phone to feel bulkier, but was surprised by how natural it felt in her hand. “It’s taller, sure,” she said, “but because it’s thinner and not as wide, it actually slips into my jacket pocket easier. I do have to shift my grip when reaching the top corners, but after a week, it became second nature.”

What stood out most to her was multitasking. With the S8’s taller screen, split-screen mode became genuinely useful—she could reply to messages while browsing maps without either app feeling cramped. On the S7 Edge, split view often meant sacrificing readability.

This example illustrates a broader trend: the perceived size of a smartphone isn’t just about raw dimensions. It’s influenced by screen-to-body ratio, curvature, weight distribution, and how apps utilize available space.

Step-by-Step: How to Evaluate the Size Difference Yourself

If you’re still unsure whether the S8 will suit your lifestyle, follow this practical evaluation process:

1. Measure Your Current Phone: Note how it fits in your hand and pocket. Does it protrude? Is it heavy?
2. Check S8 Dimensions: Compare the S7 Edge’s 72.6mm width to the S8’s 68.1mm. That’s over half a centimeter narrower.
3. Simulate the Height: Print out a life-size S8 outline (148.9mm x 68.1mm) and hold it next to your current device.
4. Test One-Handed Reach: Mark where your thumb naturally lands on the mockup. Can you comfortably tap the top corners?
5. Visit a Retail Store: Hold the S8 in person. Even if you buy online, hands-on testing removes guesswork.

Tip: Bring your phone case with you to compare thickness and edge grip. The S8 has a glass back and aluminum frame—slightly more slippery than the S7 Edge.

Frequently Asked Questions

Is the S8 harder to use one-handed than the S7 Edge?

For some users, yes—especially those with smaller hands. The taller screen means the top corners are further away. However, Samsung introduced Edge Panels and one-handed mode in the S8, which helps mitigate this. You can shrink the interface temporarily for easier access.

Does the S8 feel lighter even though it has a bigger screen?

Absolutely. At 143g, the S8 is 14 grams lighter than the S7 Edge (157g). Combined with its narrower frame, this makes it feel more balanced and less fatiguing during extended use, such as reading or watching videos.

Will my S7 Edge cases fit the S8?

No. Despite similarities, the S8 has different button placement, camera layout, and overall dimensions. Cases are not interchangeable. Additionally, the S8 lacks the IR blaster and heart rate sensor cutouts present on the S7 Edge.

Checklist Before Upgrading

• ✅ Confirm carrier compatibility (both support LTE, but check VoLTE and band support)
• ✅ Backup contacts, messages, and photos from S7 Edge
• ✅ Test S8 in-store for comfort and grip
• ✅ Plan for new accessories (case, screen protector, wireless charger)
• ✅ Transfer apps and settings via Smart Switch
• ✅ Understand that waterproof rating remains IP68 on both models

Conclusion: Is the Size Difference Significant?

The Samsung Galaxy S8 is not “much” bigger than the S7 Edge in any uncomfortable way. In fact, it’s narrower, lighter, and better optimized for modern usage patterns. The increase in screen size comes not from bloating the device, but from smarter design—thinner bezels, a taller display, and refined ergonomics.

If you valued the S7 Edge for its balance of screen and portability, the S8 improves upon that formula rather than compromising it. Yes, it takes a day or two to adjust to the taller form, but most users find the extra screen space worth the minor learning curve.
