Galaxy S8 vs Galaxy S8+ vs S7, S7 edge, LG G6, iPhone 7 Plus, Pixel XL: size comparison


The official reveal of the Galaxy S8 and S8+ is finally upon us! Samsung just now, during a special Unpacked event, made the long-awaited, much-hyped, next entries into its Galaxy lineup official, and we are happy to report that the S8 and S8+ sure are something!

Although the torrent of leaks that has been bashing us with fact after fact about the two devices in the past months has diminished the surprise somewhat, we have finally seen the duo in person and have had the opportunity to do a hands-on with both.

The most striking thing about the Galaxy S8 and S8+, at first glance at least, are their gorgeous Infinity Displays. Ditching the 9:16 screen aspect ratio, Samsung has gone for taller, narrower displays on both devices, and they sure are something to look at. With very little in the way of bezels on the top and bottom, the Galaxy S8 and S8+ manage to retain dimensions that are similar to those of their predecessors, the S7 models, all the while upping the diagonal of their displays a notch.

As we've said before, this is a new and positive trend in smartphone making that aims at utilizing the available space on our favorite pocket computers to the fullest. It's something that LG is also doing with the G6 and its 2:1 (or 18:9) 5.7-inch FullVision display, which is a bit shorter than Samsung's 9:18.5 panels, but still manages to fill up the front of the G6 quite nicely.

So, in light of this trend, and since smartphone sizes have always been an interesting topic, we have decided to pit the brand new Galaxy S8 and S8+ against the LG G6, and other current top flagships, and see how they compare in terms of size.

First up, a quick scuffle between the new Galaxies and their predecessors, the S7 and S7 edge:

The Galaxy S8 (148.9 x 68.1 x 8.0 mm), which has a display with a usable area of 5.7 inches (5.8″ without accounting for the rounded corners), is a bit taller than the 5.1-inch S7 (148.9 mm vs 142.4 mm), but it's almost the same width (68 mm vs 69.6 mm), all the while upping screen size to 5.7 inches. The curvature of the S8 no doubt helps fit more on it, but it's not the real reason for the difference in display real estate. That would be the aspect ratio of the new Infinity Display.

It's a similar scenario between the Galaxy S8+ (159.5 x 73.4 x 8.1 mm) and S7 edge – the new phone is taller than its predecessor (159.5 mm vs 150.9 mm), and just a tad wider (73.4 mm vs 72.6 mm), but the new phone ups the size of its display from 5.5 inches to 6.1 inches.

However, you should keep in mind that a 5.7-inch display with the new aspect ratio is something quite different from a 9:16 display with the same diagonal. For example, the display of the S8 is considerably taller than that of the S7, but it is almost identical in width. This means that, despite the new screen being technically larger, you are getting only a vertical bump in size, so to speak, while nothing changes in terms of width. Here is a diagram illustrating how the display of the Galaxy S8 (blue) compares directly to that of the Galaxy S7 (yellow):


Again, S8's display is curved, which too helps fit more in less, but its bend is a lot more subtle than that of the S7 edge, and more akin to what we saw on the Note 7. As you can clearly see, the 5.7-inch 9:18.5 display on the S8, although having a larger area than S7's 5.1-inch 9:16 display, is simply taller, and that's exactly the point. After all, the idea here is to have a phone that's very similar in size to what we're used to, all the while still offering a larger display area.

If you're still unsure as to whether changing the aspect ratio is a step in the right direction, just wait until you see how the Galaxy S8 and S8+ look next to some other current flagship devices. 

That said, let's now move on to a battle between the S8s and two of last year's top offerings – the iPhone 7 Plus and the Google Pixel XL.

It is redundant at this point to discuss the top and bottom bezels on the iPhones and the Pixels – everything has been said already. The iPhone 7 Plus is 9.2 mm taller than the S8, and it has a 5.5-inch screen. The Pixel XL too has a 5.5-inch display and similar dimensions to the iPhone 7 Plus, so it doesn't fare any better (or worse) than it against the sleek new Samsungs.

Here's where it gets interesting though. It's time to pit the brand new LG G6, which has a slightly shorter 9:18 (or 1:2) display, against the S8 brothers:

The G6 is one sleek smartphone that packs a 5.7-inch display in a body that's the same size as that of the 5.3-inch LG G5. Again, that's thanks to its FullVision 1:2 display.

When placed next to the Galaxy S8, the G6 is the same height (148.9 mm), but a tad wider (at 71.9 mm vs 68.1 mm), due to its screen being flat and its side bezels being a bit bigger as a result. Still, the G6 is in and of itself a glimpse into the future of smartphones – a future where devices are mostly screen on the front and almost no bezels, all the while remaining close to the dimensions of their predecessors.

In the coming year, we'll see more and more phone makers adopt similar screen aspect ratios to those of the LG G6 and the Samsung Galaxy S8/S8+. While no other manufacturers have made any concrete announcements yet, numerous rumors suggest that Apple may be next in line to adopt a similar approach to designing one of the upcoming iPhone models, and if that happens, it would only be a matter of time before the entire industry gets on board with the idea.

And, as a bonus, here's a bunch more size comparisons between the Galaxy S8/S8+ and other current smartphones:

It's less than 7 mm lol doubt your eyes or even you hands will feel the difference plus you have to wait for the real thing for final judgment.

I hated going up in size from the GS4 to the GS7. This is another big jump. I'll be very interested to see how big the next iPhone is because a smaller phone is just so much easier to use one handed and also to keep in the pocket. The only thing that kills me about the iPhone is that pathetically low screen resolution. I see Apple keeping the same screen on the 7S or whatever it will be called and waiting until 2018 to go AMOLED and a higher resolution for their "regular" sized model.

Huh? The S4 was 5" display. The S5 and S6 both have a 5.1" display. The S7 retains the 5.1" display. How is going from 5.1 to 5.7 going to be a huge jump? You are talking .6MM. Please grab a ruler and see how much space a MM takes up. The S7 edge is 5.5" and the Note 7 was 5.7". When I hold the S7 edge, it does feel smaller, but it does because the curve is much sharper on the S7 vs the Note 7. My wife has tiny hands, but she too said it felt much smaller so I showed her why. I placed the devices on top of each other and showed here where the difference is. From the photos of the sides, the S8's are both goign to feel a lot like the Note 7. Because even though the Note 5 and 7 have the same size display, the Note 7 felt smaller because of the curve. You have to stop trying to tell your brain with your mouth that 5.7" is some gigantic size vs 5.1 because it isnt. The device is simply goign to be taller. I think if you hold the S6 edge or S7 edge and then when the S8 comes out, you will see they won't feel very different,

So Techie, What do you think the N8 screen will be? same as S8+ with smaller battery and s-Pen? or 6.5"?

64. TechieXP1969

Posts: 14967; Member since: Sep 25, 2013

I will go with the rumors. 6.3 or 6.4". Will be maybe 2MM wider vs the S8+ due to the S-Pen silo. Battery? 3500MaH sounds like a good safe number. But since the phone is taller, there is room for more battery. I will go as high as 3800MaH.

The screens are measured in inches ("). Therefore 0.6" is 1.54cm, not 0.6mm. The screen difference is quite significant but is slightly mitigated in ergonomics when the screen is curved. The difference is still very noticeable.

S4 to S7 was an inconsequential jump. You're fooling yourself if you think that was a big change.

Who ever said it would be? But if you look at the photo, you can see the S8 is the same size as the S7 edge, but has a larger display by .2MM. Its obvious a 6" display can't fit in the same size phone as a 5.7" device. All one has to do is do the math. The problem with a 6"+ display is, it would have to be made taller to fit an aspect ratio vs being wide. The S8 is the same size as the S7 edge and still has a larger display. The S8+ is gonna be a monster to hold, but for anyone who can deal with Apple's iPhone Plus models and its terrible screen to body ratio, no one should complain about the larger S8+. The S8+ appears to be the same height and width as the iPhone 7 Plus. But the screen to body ration on the S8+ is far better.

Very nice article, a lot of people are now trying to decide on their upcoming phones. I have and S7 Edge, and I can't see myself using a phone which will be 10mm taller than the S7 Edge (iPhone Plus owners have no other choice if they want to stay Apple, but we do). So the S8 or G6 remain the only options for people who want pocketable devices, but then the G6, while looking perfect to me and much better than S8/S8+, has much worse battery life compared to the S7 Edge, from what I read until now (especially compared to the Exynos which has superb, 2-day battery life with some tweaks), the Snapdragon 820/821 with its 4-core design is just not very efficient. And the S8 will probably have a smaller, 3000 mAh battery and combined with the larger screen will probably cancel any advantage of the 10nm Snapdragon 835 and provide the same battery life as the S7 (which was not very bad. Hopefully I'm wrong about the S8 battery life). Another issue is that Package Disabler, one of the great ways to increase battery life to up to 2 days on the S7/Edge, is Samsung-only (uses Knox), and the G6 cannot take advantage of this. One major problem with the S8/S8+ is that curved screens cannot be protected, current screen protectors are rubbish (I'm using my S7 Edge unprotected because of that, and the screen already has a few tiny scratches). I truly hope Samsung will release some official screen protectors to offset LG's claims of screen reliability, it would be great. I think that the S8 will sell better than S8 Plus this year. Design is a bit ugly, but functional and the innards will be top notch.

There are cases for it that would work. Those body armor cases.. or whatever they are called.. the thick polymer plastic that sticks to the phone... would work well.

The Note 7 has the SD820. It last 2 days on a single charge even with no settings changes out the box. The S7 edge only has a slightly larger battery vs the Note 7. My wife says the S7 edge is using more power than her Note 7 did and from my usage of the S7 it did for me too. But I use it for and it still lasted me 2 work days, if I didn't web browse too much.

I can agree with you on the battery, my N7 was incredible on battery and now with the s7edge it chews battery quicker. Not sure why, hoping the Nougat update with N7 battery features help

The claim that the edge of Samsung's phone can't be protect is simply a lie and is false. There are 9H curved screen protectors that I used on my S6 and Note 7 and I have dropped my phone and cracked the extra glass, but not the actual phone itself. That claim is false and will never be true even if millions of people repeat it, This is the type of screen protector you must get:http://images.mobilefun.com/graphics/450pixelp/60110.jpg Using with a case you will never break the original glass, unless you drop it out a window. https://www.youtube.com/watch?v=UzIRNg8HxRs In this video this guy dropped his S7 edge with a 9H tempered glass full protection and he didnt break the original glass. I just debunked your entire claim! As long as you get a tempered glass that covers 100% of the curved display, you will NEVER break the original glass and unless you are purposely out to just damage your phone. This guy dropped his phone from near 5' and the glass didn't break, only the screen protector.

Do you know how big a millimeter is? You're talking 5/8th's of an Inch. That is not much bigger at all. I only suggest going to a local carrier and looking at them. https://flic.kr/p/TpvuGS Look at them side by side. The S8 is not that much bigger. Crying over spilled milled. The S8 is smaller than the iPhone Plus models. The S8+ is 1MM taller vs the iPhone Plus models. You really trying your best to make a big deal about nothing. You havent even held the phones.

Correct me if I'm wrong, but didn't the leaks state that the regular sized S8 had a display of 5.8 inches? not 5.7 inches?

Galaxy S7 - 142.4 x 69.6 x 7.9 mm - 5.1" Flat Galaxy S7 edge - 150.9 x 72.6 x 7.7 mm - 5.5" Curved Galaxy Note 7 - 153.5 x 73.9 x 7.9 mm (6.04 x 2.91 x 0.31 in) - Curved (less pronounced) Galaxy S8 - 140.1 x 72.2 x 7.3 mm - 5.8" Curved Galaxy S8+ 152.4 x 78.5 x 7.9 mm - 6.3" Curved Based on the CAD, the S8+ will be slightly shorter than the Note 7, and slighly taller than the S7 edge. It will be wider than any previous S/Note model, but equally as thin as the S7/Note 7. The S8 is shorter than the S6/S7. Not as wide as the S7 edge and thinner than the S7's.

Hope these sizes are not 100% accurate. Wish the S8+ is same size as the s7 edge please samsung dont make it longer.

But... If the S8 Plus is too large for you, you could just go with the S8...
