Application icon size in iOS

Question

What should be the application icon resolution in Xcode ?

I couldn't find the sizes for 2x and 3x.

Answer 1

For iPhone, the standard resolution of app icon is 60*60px. And the corresponding 2x and 3x versions of it are 120*120px and 180*180px respectively.

For iPad, the standard resolution of app icon is 76*76px. And the 2x version is 152*152px. There is no 3x app icon on iPad.

Answer 2

I suggest you the app icon template which creates all of the versions for you. You can see it on this link. It is the easiest way to generate those.

@3x or @2x can be upscaled from @1x But to answer your question what are those.

Normal device - 1 pixel = 1 point@1x (Older iPhone and iPad devices)

Retina device - 4 pixels(2 x 2) = 1 point@2x (iPhone 5+)

Retina iPhone6 and iPad - 9 pixels (3 x 3) = 1 point@3x (iPhone6+)

iPhone app icon standard resolution is 60*60px.

iPad app icon standard resolution is 76*76px.

You need all 3 of those versions because there are three kind of apple devices.
