The New iPad - Time for App Developers to Upgrade Their Graphics
With the announcement of Apple's new iPad with the higher resolution Retinal display, it means that iOS developers will have to update the graphics for any apps that run on the new device.
Apple's new iOS Human Interface Guidelines require a minimum of 10 icon sizes (more if your app needs document icons)! Its time for all app developers to re-size and redraw.
In descending pixel order, the app icons for iPhone and iPad apps are:
1024 x 1024 - Hi-Res app icon for the App Store
512 x 512 - Standard app icon for the App Store
144 x 144 - App icon for New iPad
114 x 114 - App icon for Hi-Res iPhone and iPod Touch
100 x 100 - Hi-Res iPad Spotlight search results
72 x 72 - Standard app icon for the iPad
58 x 58 - Settings and Spotlight search results for Hi-Res iPhone and iPod Touch, and Settings for the new iPad
57 x 57 - App icon for standard iPhone and iPod Touch
50 x 50 - Standard iPad Spotlight search results
29 x 29 - Settings and Spotlight search results for standard iPhone and iPod Touch, and Settings for the iPad
There are now six sizes for the launch images as well:
2048 x 1496 - Landscape for the Hi-Res iPad
1536 x 2008 - Portrait for the Hi-Res iPad
1024 x 748 - Landscape for the standard iPad
768 x 1004 - Portrait for the standard iPad
640 x 960 - Hi-Res iPhone and iPod Touch
320 x 480 - Standard iPhone and iPod Touch
For the optimum appearance, all the existing graphics used by an app will also need to be upgraded as well.
Photoshop will be very busy.
