Of Device Screen Sizes and Aspect Ratios

It doesn't pay to be certain about anything these days

Just a random thought for a Saturday afternoon: While I’ve had some pretty strong opinions about what I perceive to be the optimal size and aspect ratios of the screens on smart phones and tablets, this fall’s bumper crop of new devices has me rethinking things. And I don’t mean I’ve arrived at new optimal sizes and aspect ratios. I mean there’s no one answer.

For example, for the past few years it’s been pretty easy to complain that the iPhone’s screen size was too small compared to the ever-increasing screens on competing Android devices … because it was. (My comment that the iPhone 4S was “perfect for women and children” was infamously—and incorrectly—turned on its head to appear misogynistic when in fact it was just about the size of the device.)

Apple responded to this obvious complaint in a wonderfully non-standard way. Instead of creating a bigger screen with the same aspect ratio as its predecessor, it provided the iPhone 5 with a screen that was stretched out only vertically. That is, while the pixel count horizontally remained at 640, Apple increased the vertical pixel count from 960 to 1136.

Apple’s decision to increase the size of the iPhone 5 screen only in the vertical was explained by Apple vice president Phil Schiller during the iPhone 5 launch event. So while the firm moved from a 3.5-inch screen to a 4-inch screen, it obtained a natural 16:9 aspect ratio that it conspicuously does not use on its other mobile products, including the more recently released iPad mini. Why?

“It is really easier to make a new product that is bigger, everyone does that,” Schiller said, noting that the ‘design center’ for a phone is your thumb. “A phone should be easy to use with … a thumb. It should be easy to send messages, type emails, surf the web, and that’s how we designed iPhone 5.”

In other words, had Apple simply moved to a larger 4-inch screen and increased the size of the screen in both the horizontal and vertical, as other phone makers have done, many users wouldn’t be able to use the device with one hand.

Now, as a bigger guy with big hands, I don’t mind the bigger phones, but I can see the point. And certainly many people aren’t too interested in a Lumia 920 or the even huger Samsung Galaxy Note because of the screen sizes. But conversely, others are attracted to these devices for exactly this reason. One size doesn’t fit all.

On the tablet front, I’ve long argued that a 7-inch device makes a lot more sense than a 10-inch device when that device is primarily a content consumption device and not a creation device, like a tablet PC or hybrid laptop. I made this argument when the first iPad came out and, since then, I’ve really enjoyed smaller devices like the Kindle Fire, Kindle Fire HD, and Google Nexus 7.

But screen size wasn’t the only physical difference between the iPad (pre-mini) and these other devices: The competing 7-inch tablets all offered widescreen aspect ratios and not the boxy 4:3 aspect ratio Apple’s used on the iPad. I was curious whether Apple would go the iPhone 5 route with the iPad mini (using a 16:9 aspect ratio) or whether it would retain the classic 4:3 screen type of its predecessors.

As you probably know, it chose the latter route. And its explanation of this decision, which is initially a bit odd given that the iPad mini, like the iPhone 5, is designed for one-handed use, goes as follows. Apple wanted the new iPad to be a no-brainer for developers so that all existing iPad apps would just run. (On the iPhone 5, existing apps all run too, but they leave black bars on the sides of the wider new screen. And don’t get all hatey on me, this is exactly how Windows Phone 8 does it on HD displays too.) “The iPad mini is the most usable of all these [small tablet] devices,” Mr. Schiller explained a month later at the iPad mini launch event. “All of the software created for iPad works on iPad mini … unchanged.”

What’s interesting about these two devices is how different they are from the rest of the market. Other smart phone makers tend to produce much bigger screens, period, screens that are bigger in both directions than the iPhone 5. (Certainly, no company makes a tall, thin screen like that on Apple’s device.) And tablet makers have generally eschewed the 4:3 aspect ratio of the iPad/iPad mini and have gone with widescreen designs.

I’m not sure which I like better.

My current smart phone, the HTC Windows Phone 8X has a 16:9 widescreen (1280 x 720) display. This screen is 4.3 inches, so it’s a bit bigger than the iPhone 5 screen. And while I love this device, I have the same issue typing on its virtual keyboard that I do on all iPhones: They keys are a bit small (probably tall and thin really) compared to the phones I previously used. So I find myself making more typing mistakes than I had previously.

The thing is, the virtual keyboard on this device isn’t that much smaller than it was on the Focus S or Lumia 900. But it is smaller. (The iPhone keyboard hasn’t changed. It’s just small.)

Meanwhile, I’ve been using a Kindle Fire HD since it came out and really enjoy the device, though as I noted in my review, the bezels around the screen—which is tall and wide—are oddly huge. The Fire HD is great for reading books and for watching video content, and I’d never really considered any particular shortcomings in the device.

Until I got an iPad mini. This device has a wider screen, and much smaller bezels, and is lighter and thinner. Yes, video content is letterboxed. But who notices that? Web content looks great, and the reading experience is great too. The screen, though lower-resolution, looks great to me. (I suspect a future retina version of the mini will change my mind. I can wait.)

These new devices have thrown my worldviews out of whack.

I really can’t decide between 16:9 and 4:3 smart phones and tablets anymore. Each has its pros and cons. And while the devices you choose won’t typically hinge on this particular spec, maybe that’s the point: It shouldn’t.

One final bit of confusion. Sitting in the press room at BUILD, I ran into PC World’s Melissa Perenson, who was carrying a genre-busting Samsung Galaxy Note II. This device is somewhat ludicrous on the surface with its 5.5-inch (and 16:9, 1,280 x 720) display. But looking at this beast—which is actually really thin and light as well—it occurred to me that phone calls were not my most frequent activity on a smart phone anyway. And email, calendar, web browsing, and other tasks are much more enjoyable—especially to my aging eyes—on such a device.

Sigh.

It is absolutely impossible to find a Windows 8/RT tablet with an aspect ratio other than 16:9, despite the fact that portrait mode Windows at that aspect ratio is comically awkward.

I mean, Apple put some thought into it. In landscape, 16:9 is too short, and it's awkward to hold. In portrait, it's too narrow. As you say, who gives a crap about letterboxing? The only reason to use 16:9 I'd consider valid is it works better with physical keyboards. But hey, it's cheaper, so every other tablet manufacturer went with it.

Apple has 90% market share with 4:3. Not one Windows or Android tablet manufacturer thinks maybe it's worth giving it a try? Crazy.

not ALL of the Win8 devices are 16:9. The HP Elite Pad 900 is 1280x800.

I love the 16:9 aspect ratio for reading. As a med student, it lets me see a whole lot more text without having to scroll so much. In fact, on my desktop setup, I have a 3 monitor configuration, with the primary monitor being a portrait 16:9 screen.

A couple of thoughts.

1) My eyes and their field of view is much closer to a 16:9 ratio.

2) Whether 4:3 or 16:9 is a better layout is largely driven by the organization and layout of the OS.

3) Perhaps the only thing where 4:3 outperforms 16:9 is in the vertical orientation and the balance of the device. **Refer to point #2

Any particular reason you have ignored the original Windows Phone aspect ratio of 15:9, which Nokia devices seem to be carrying forward @ 1280x768? Lumia 920 is an obvious one. I really don't like 16:9 for anything, portrait or landscape, except my TV.

I've long suspected that manufacturers' love of wide aspect ratio screens is also about money, because they're not really practical. The point is, you can cut more x-inch diagonal 16:9 or 16:10 panels from the same sheet of glass than you can 4:3 panels, because the physical area is smaller.

For the manufacturers the benefit is clear: They can still advertise that their device has the same diagonal as before, although the panel is actually smaller.

For the user, not so much: As you said, who cares about letterboxing and in any case, watching movies isn't the only thing you do on any of these devices. For all other activities, wide-aspect screens are a step backwards. My old 4:3 Lenovo was radically more useful than my current 16:9, and I find it incomprehensible that a business computer would use that aspect ratio.

Maybe you should reconsider your love for the 8X. You get smaller keyboard keys on the 8X's narrower screen than you did on your Lumia 900 even though both phones have 4.3 inch screens. The Lumia 920 will give you slightly larger keyboard keys than the Lumia 900 on its 4.5 inch display.

You claim that Windows Phone adds black bars on its HD displays. Since the Lumia 920 is the same 15:9 aspect ratio as previous Windows Phones there are no black bars. Strike two again the 8X.

Bezels are great to help hold the device. Not having seen or held an iPad Mini, I'll withhold judgement on it and its lack of a bezel & the ability to hold it one-handed. I've no trouble holding the Nexus 7 and reading stuff on it, and the bezel on the long side isn't huge like the Fire HD or nearly non-existent like the iPad Mini.

The iPhone 5 (and iPod Touch v5 (which I have)) isn't quite useable with one hand as Apple likes to claim. Maybe my hand & fingers are too large & long? Maybe I'm "Holding it wrong." (tm Apple). And I find the keyboard on it annoying as it's far too small to use efficiently. I keep feeling I need to file my fingers down to use it.

"And I find the keyboard on it annoying as it's far too small to use efficiently. I keep feeling I need to file my fingers down to use it."

;-)) I have always found Apple's obsession with one-hand operation strange. After switching to a 4.3" Galaxy S2 from an old iPhone 3GS I have never once had any problems with operation. But I DO have problems now when I look at my friends' iPhones with their teeny-tiny screens. The screen area just seems so small and cramped.

When will hardware ans software makers wake up and provide a device with a 1.60 aspect ratio that shows subtitles UNDER the video!

1920X1200 is what I'm waiting for.....

The only time I use my surface in portrait mode is when I am playing pinball. Works great.

For reading, most content comes in multi-column format so I don't see it as an issue. If Kindle would add a two column layout, it would be perfect. Like a real book.

portrait mode is great. I even have my desktop in portrait mode. I have a 3 monitor setup with the primary display being a vertical portrait monitor. It let's me see much more text while reading so I don't have to scroll back and forth so much. and 16:9 makes it so that there's even less scrolling.

as for a phone, that's the only time 16:9 may be too narrow.

but for a tablet or PC, 16:9 is the way to go. A lot more usable real estate. You guys don't remember the days of the analog TV and the 4:3 VGA monitors? let's leave that stuff in the past.

Kind of wish that windows phone had more variety of sizes, wouldn't mind adding a 4" screen phone and a 5.5" super phone. Would they dare a 7" phone-like device (that comes with a great speaker/mic) that was Win phone 8 and not RT?

Ah, So that's why all your articles have typos. ;)
