Icon Sizes for iPhone, iPad, and iPod Apps

When making apps for all generations of Apple iPhone, iPad, and iPod devices, application developers must use a specific set of images meeting Apple’s stringent Custom Icon and Image Creation Guidelines. As a bare minimum, one needs an application icon and a launch image. However, Apple recommends that apps supply quite a few extra images, such as an icon used by the system when displaying Spotlight search results and Settings. Apps that can handle certain file types (such as documents, audio, or video formats) will require icons to represent their supported file formats. Most apps will also require a fair share of images to draw their navigation bars, tab bars and toolbars.

As a rule of thumb, Apple imposes stringent requirements on how to design these icons so that each app running on the iPhone, iPad, or iPod platform conforms to general specifications and visual guidelines. Specifications ensure that your app looks in line with what’s offered by Apple and other developers.

Making Use of Retina Displays

Apple’s innovative pixel-packed Retina display packs more pixels into a small area than was imaginable just a few years ago. These high-resolution displays allow showing the highest definition graphics to create crisp images with the feel of dimensionality and depth. As such, Retina displays will naturally require higher resolution icons to be employed in navigation bars, toolbars, and tab bars. Texture-reach, detailed, and more realistic images with multiple small elements and engravings will produce the most pleasing effect of three-dimensionality and depth. To display great graphics on Retina displays, developers need their icons in resolutions of 60×60 pixels.

Icons for Navigation Bars, Toolbars, and Tab Bars

While, generally, apps can use artwork in any reasonable size or resolution, there are several common sizes your icons must include in order for the system to draw them properly in navigation bars, toolbars, and tab bars.

For iPhone and iPod touch toolbar and navigation bars, Apple requires the image resolutions of 20 x 20 pixels (standard resolution) and 40 x 40 pixels (high definition, for Retina displays). Toolbar and navigation bars in iPad apps employ 20 x 20 pixel versions exclusively.

Tab bar icons are specified in two resolutions. 30 x 30 pixel versions are used in tab bars displayed in iPad, iPhone and iPod touch apps in standard resolution. In addition, iPhone and iPod touch apps employing the Retina display will benefit from having super-sized images in sizes of 60 x 60 pixels.
