When developing an app specifically for the iPhone 6 Plus, what resolution should the app be designed for? Should it be 1242×2208 or 1080x1920? Will an app designed for 1080x1920 fill the entire iPhone 6 Plus screen? Are there guidelines from Apple on this issue? I haven't found any. Thanks.

Apple's guideline for all devices is to stop hard coding screen sizes and use Autolayout. If yo are targeting the iPhone 6/6+ you can assume iOS8 and Xcode 6 which makes Autolayout much easier.

It you really want to work to a specific screen resolution, you should use 1242×2208 which is downscaled to 1080x1920 in hardware.

  • Thanks. If I want full fidelity on the iPhone 6 Plus, and do not intend for the app to be run on any other type of device, should I design for 1080x1920 to avoid the downscaling? – Marc Zehngut Sep 24 '14 at 16:39
  • Depends on the app and technology you are using. For UIKit and standard apps use AutoLayout. For games and 2D/3D you might wan to design for the exact dimension. In general, I would be wary of focusing on a single specific screen size. Make you app flexible. – Rog Sep 25 '14 at 08:00
  • ...and you can't avoid the downsampling on the iPhone 6+ it happens to all apps. Apps 'think' they're running at 1242×2208 but the HW down samples. So you should design for 1242×2208. http://www.paintcodeapp.com/news/iphone-6-screens-demystified – Rog Sep 25 '14 at 08:02
