App icon Spec Reference table

Transferred from: http://www.cocoachina.com/appstore/top/2012/1105/5031.html

Like I can't remember iOS app icon pixel size developers a few, I often need to query different devices on the application size, in order to facilitate their own, convenient for everyone, I made the following chart for your reference.

What is the pixel size of the

IPhone, Ipodtouch, and general-purpose app icons?

iphone and Ipodtouch apps need to apply all the icon pixels in general, and you might wonder why iphone apps need an ipad app icon because an iphone app can also run on ipad.

Instead, ipad apps don't run on iphone, so the ipad app has its own icon pixels.

Required icon:

AppStore icon: 1024x1024pixels

iphone Home screen icon: 57x57, 114x114 (retina) pixels

ipad Home Screen icons: 72x72, 144x144 (retina) pixels

Optional icons:

IPhone, Ipadsettings, iphonespotlightsearchresults:29x 29, 58x58 (retina) pixels

What icons are needed for ipad apps.

Because apps that only apply to ipad can't run on the iphone, you don't need that many icons.

Required icon:

AppStore icon: 1024x1024pixels

ipad Home screen icon: 72x72, 144x144 (retina) pixels

Optional icon:

ipadsettings:29x29and58x58 (retina) pixels
