Here's Why The Displays In New Phones Are So Weird And Wide

Most of the major smartphones of spring have been announced, and we noticed something curious. The LG G6 and Samsung Galaxy S8 are both rocking big displays with an aspect ratio larger than the 16:9 you're used to on your phones, television and desktop displays. These phones have some of the widest aspect ratios ever seen on a mobile device. Is this the future of our smartphones or just another fad (like modular handsets)?

We'll guide you through the ins and outs of aspect ratios and explain why the 18:9 display is one to watch out for in the future.

What aspect ratio is, and why you should care

Aspect ratio is the relationship between the height and width of a rectangular display. Your laptop has one, your tablet has one, and your smartphone has one -- it's a measurement of how tall or wide a screen is.

You'll usually see it expressed as a ratio, like the 4:3 ratio on older TVs, or the widescreen 16:9 ratio on new ones. It's also sometimes written as a decimal with the larger figure divided by the smaller (4:3 is 1.33 and 16:9 is 1.78). It doesn't tell you how big a screen is, just the proportional relationship between the height and the width, so on a 16:9 screen there will always be 16 pixels in one direction for every 9 pixels in the other.

Of course this makes a pretty big difference to your user experience, as you'll know if you've ever tried to watch a widescreen movie on an ancient TV and seen the screen get swallowed up by huge black bars at the top and bottom.

For just about any gadget, from a television to a smartphone, its aspect ratio is driven by what's being shown on it: for most hardware that's video content, which is why widescreen displays have become the standard.

But for many tablets and laptops, apps and web browsing also need to be considered. In portrait mode you're talking about a display that's taller than ever, and in landscape mode you're going even wider than widescreen.

LG and Samsung have fired the starting gun and it's going to be an interesting year for anyone who likes to keep an eye on smartphones or aspect ratios (or both). If some kind of substantial shift does happen - if the 18:9 display in the G6 or the 18.5:9 display in the Galaxy S8 become defacto, than OS makers and app developers are going to have to make adjustments.

A brief history of smartphone aspect ratio

The launch of the first iPhone is a good a starting point as any when it comes to charting smartphone history, and that particular device arrived with a screen resolution of just 480 x 320 pixels -- that's an aspect ratio of 3:2, which you'd be hard pushed to find on a phone today, but which is now showing up on 2-in-1s like the Samsung Chromebook Pro and the Surface Pro 4 from Microsoft.

Even as Apple upped the resolution of the iPhone, the aspect ratio stayed the same, until the iPhone 5 in 2012, which featured a 1,136 x 640 pixel, 16:9 screen for all your widescreen movie and gaming needs. Both the latest models have more pixels but that same 16:9 aspect ratio.

Outside of Apple, the trajectory is less easy to track, but it follows a similar pattern. You might not be surprised to hear that Samsung went 16:9 the same year Apple did, with the Galaxy S III (back in the days when they used Roman numerals). Meanwhile the Nexus line switched to widescreen in 2011 with the Samsung-made Galaxy Nexus, after the first two models opted for an older 1.66:1 standard.

There have been too many phones launched since 2007 to mention them all individually, but the broad trend has been towards widescreen, 16:9 aspect ratios since the turn of the decade, first at 1,920 x 1,080 pixels (Full HD) and then at 2,560 x 1,440 pixels (Quad HD).

At least part of the reason for that has been video: while TV and cinema have used widescreen formats for decades, it was only really at the turn of the 2010s that we started watching this kind of content on our phones (YouTube went widescreen in 2009), and so 16:9 makes sense to keep those letterboxing effects to a minimum.

The next logical step would be to follow TV sets into the realm of 4K -- and the same 16:9 aspect ratio -- but that's not necessarily a given. Cinema and television formats could be on the verge of another serious shift, and that in turn might mean that 18:9 is going to be the future of our smartphones.

The LG G6 and super-tall phones

LG kicked off 2017 with the launch of its unusually tall, 18:9 aspect ratio LG G6, running at a resolution of 2,880 x 1,440 pixels, and the Samsung Galaxy S8 was announced this week offering a slightly larger 18:5 2960 x 1440 display. Besides bezels almost completely disappearing, what's going on?

Part of the thinking, as LG has openly explained, is to do with the proposed Univisium 2:1 format put forward by Italian cinematographer Vittorio Storaro. It's not been broadly accepted as yet, but it's designed to find a happy compromise between the competing widescreen aspect ratios of television (typically 16:9) and movie theatres (typically a wider 2.20:1). It was first suggested in 1998, but Univisium is now starting to gather momentum -- new shows on Amazon Video and Netflix have already been shot using this aspect ratio (or very close to it).

That's video covered, but it also makes more sense for multitasking with apps on bigger screens. With an 18:9 aspect ration you can have one app on top of another in portrait mode or use them side-by-side in landscape mode. There's also more to see on webpages and in those ubiquitous endless-scrolling apps where the content never stops, like Twitter and Tumblr.

Right now it's just too early to say whether 18:9 will take off, but if LG and Samsung commit themselves to the standard then it's got a great chance of getting a foothold in the market. Getting the entertainment industries to switch over may well be a longer process, but existing video formats still look fine on a 18:9 screen.

As noted in our LG G6 review that extra height (or width, depending on how you're holding it) is something you quickly get used to. LG has been pretty clever with how it's used the extra space, one example being the way your most recent shots stack up at the side of the shutter window in the camera app.

With two of the most popular smartphone makers leaning into this super aspect ratio this year there's a good chance 18:9 could be the new trend in smartphone displays -- particularly those found on Android devices. But Apple and Google still have to announce their new phones in the fall. Which means these super wide phones might still just be a super fad.



    Why can a cinema ratio be 2.20:1 yet an LG phone has to be 18:9, instead of 2:1?

    Maybe, they could call it 2.00:1 to try and make it look more impressive, rather than trying to disguise the fact.

      They aren't trying to disguise a fact, they are trying to help uniformed people comprehend it better. 16:9 is so ubiquitous that seeing 18:9 makes more sense to people when comparing the two than 2:1 might.

    I feel I'm alone in this but I try my best to avoid media consumption directly on my phone so I'm glad phone manufacturers are looking at other aspect ratios if they offer more utility for other features. (I also dislike the constantly increasing screen size for the same reason).

    A phone is mostly a tool for me, something to make my life easier and simpler, but not a device for *direct* media consumption. (I'll note that I have no issue with using a phone as a media host/pass-through, I listen to music through headphones and cast video from phone to T.V.)

    There have been too many phones launched since 2007 to mention them all individually, but the broad trend has been towards widescreen, 16:9 aspect ratios since the turn of the decade, first at 1,920 x 1,080 pixels (Full HD) and then at 2,560 x 1,440 pixels (Quad HD).

    Maybe you meant 1280x768 at the turn of the decade. Full HD: 1920x1080 didn't arrive until December 2012 and wasn't widespread until 2013. I thought the Sony Xperia Z was the first Full HD phone and it was Feb 2003. Although according to Wikipedia HTC Butterfly was the first released in December 2012, though it was Japan only.

    As for whether 18:9 (2:1) will be the new trend, maybe in high end. The low/mid range is unlikely to move that way anytime soon and that's where the bulk of sales are. The problem at the low/mid range becomes cost. 18:9 is ok at the high end when you're eliminating bezels and making crazy expensive devices. It's less effective when you're shaving dollars from the manufacturing costs.

    I suppose it'd be possible they've use a lower res variant with the 18:9 aspect ratio, something like 1280x640, maybe even 1920x960 but it would likely end up with a weird looking phone that still has large bezels and a tall, skinny screen.

      Full HD: 1920x1080 didn't arrive until December 2012

      What? I bought my first 'big' TV in 2008, and got a 720p because it was on sale. They were liquidating stock because the 1080p TVs were coming in. I specifically remember people bugging me over the fact I'd bought a 720p when 1080p was the new thing. I'm pretty sure my Xbox 360 was capable of 1080p content in 2009 / 2010 as well.

        This is an article about phones screens not TVs or movie projectors. It's even in the quote I used.

    Goddamnit! A series 2 Stranger Things spoiler in the middle of the article.

    Im all for more screen , however if it has the effect of making the devices narrower to make them more usable , im not a fan .
    i measured my G5 against the G6 the other day , and G6 display is approximately 3mm narrower !
    For a lot of people thats probably fine , but if your a clumsy git with largeish Fingers it makes keyboarding even more difficult , and if you put it in landscape the ceiling is now even shallower so depending on how good your eyes are and the size of your characters and keyboard, you may not even be able to see the typing box .
    This is a deal breaker for me , i definitely wont be looking at the G6 , and i suspect the S8 either ,
    i cant find any actual display dimensions for the S8 + so i`ll have to wait and see in store .
    Its not a good trend for me , and phones like the mate 9 ......... and even the iphone 7+ which i may never have considered as im not really an ios fan may now be on the table (Insert stunned mullet look ) .

      Sorry for the late response but i agree with you totally. What's the point of having a large screen if it's going to put up black bars on the side thus reducing your image size. We hated the black bars needed on 3 to 4 ratio TVs in the olden days and so we all rushed out and bought wide screen TVs. By doing this (18 to 9 ratio) it means that my smaller galaxy note 5 screen will show a larger picture than the skinny note 8. That's just plain stupid and i hope this fad fades away quickly.
