We’ve just spent a week investigating the device resolutions in use around the world between May-July 2015 for our device list in Fluid UI. We thought it would be handy to share this research on our blog for everyone to see.

The following graphics and tables detail all of the current common resolutions for devices, their point/density pixel resolution and various other details along with the market share for those devices. We hope it will be useful to use as a baseline for working on cross platform/device projects and will help to make sure your work is as accessible, usable and beautiful as possible.

North America is a little more predictable, but not by much, with three resolutions having a market share of above 15% and two others above 5%. The prevalence of iOS device resolutions is also far more noticeable in the North American market.

The impact of iPhone 6 +

Apple are famous for putting a lot of effort into keeping their phones as simple as possible to design for. But with the iPhone 6 and 6+ they have finally given in to market pressures to launch a larger device, resulting in the first real fragmentation of screen sizes on the platform.

Full resolution assets for the iPhone 6+ are created at 1242x2208 and scaled down to 1080x1920 by the phone itself when displaying. For more information, see here.

Android

Android screen density distribution is of course a bit more varied. The following table details the various Android models which hold relatively large market share along with their screen resolutions.

Windows Phones and Tablets

windows phones and tablets display

Late to the party and with a fairly small overall footprint, windows screens are mostly limited to the Microsoft/Nokia released devices, which come in two broad resolutions - 480x800 (5:3) and 480x854 (16:9). Tablet resolutions vary a good bit more and these often blur the lines between laptops running the same windows operating system.

Windows Phones

Model PPI Ratio Viewport Market Share
Nokia Lumia 520 233 PPI 5:3 480 x 800 23.2%
Nokia Lumia 630 221 PPI 16:9 480 x 854 9.7%
Nokia Lumia 625 199 PPI 5:3 480 x 800 7.1%
Nokia Lumia 530 245 PPI 16:9 480 x 854 5.1%


Windows tablets
Windows tablet resolutions are more varied, with the following all having some penetration:

1024 x 768 1280 x 800 1280 x 1024 1366 x 768 1920 x 1080 2560 x 1440


Overall

There is less fragmentation in the environment than originally anticipated and many of the device resolutions, while constantly increasing in terms of total pixels, are maintaining the same aspect ratios of their predecessors. Combined with a DP/Point based approach to designing, it should remain possible to deliver content, particularly on web without additional complications.

Below is our output graph of device resolutions along with their DP / point equivalent which we will be updating Fluid UI with. We look forward to seeing you there.

Bonus content: The wearables

We don’t have much to add here and the sales and growth of this market is still to be deeply understood, but we include them as we’ve done the research for our Fluid UI device list as we have libraries for them.
