In an email sent out to iOS developers today, Apple has announced a new rule that requires all apps to be submitted for approval with high resolution 1024 x 1024 icons and artwork. That’s a higher resolution than the display built into the iPad 2 — for an icon.
Apple’s email reads:
Starting in July, newly submitted iOS apps require high-resolution icons and cover art. Large icons and Newsstand cover art must have a minimum resolution of 1024 x 1024 pixels. To change your app icons or cover art, go to the Manage Your Applications module on iTunes Connect. For more information, see the Custom Icon and Image Creation Guidelines in the iOS Developer Library.
Of course, these icons are designed for Apple’s latest iPad, which features a 2048 x 1536 Retina display. Until now, 1024 x 1024 icons have only been “recommended” for the tablet, but Apple is now enforcing this size to ensure all icons are as beautiful as they can be..
