What size should apple-touch-icon.png be for iPad and iPhone?

Question

Are Apple touch icons bigger than 60x60 supported, and if so, what dimensions should I use for the iPad and iPhone?

Answer 1

The relevant documentation on Apple's site, Specifying a Webpage Icon for Web Clip.

There is no need to put anything in the head of your document. If no icons are specified using a link element, the website root directory is searched for icons with the apple-touch-icon or apple-touch-icon-precomposed prefix.

For example, if the appropriate icon size for the device is 57 x 57, the system searches for filenames in the following order:

• apple-touch-icon-57x57-precomposed.png
• apple-touch-icon-57x57.png
• apple-touch-icon-precomposed.png
• apple-touch-icon.png
