What size is the iOS App Store icon?

1024×1024 pixels, with no transparency and no alpha channel. It is the icon shown on your store listing and the source every smaller size should be generated from.

How many app icon sizes does iOS require?

A universal app needs well over a dozen renderings, covering home screen, Settings, Spotlight and notifications at both 2x and 3x, plus iPad variants and the 1024px store icon.

Why does my app icon have black corners on device?

Your source has transparency. iOS applies its own rounded mask over an opaque square, so any transparent area composites to black. Export a full-bleed opaque square with square corners.

Supply a fully opaque square. iOS applies the rounded-rectangle mask itself, so transparent corners become black wedges and pre-rounded corners double up.

The complete table of iOS icon sizes — home screen, Settings, Spotlight, notifications and the 1024px App Store listing — with the point size, scale factor and resulting pixel dimension for each.

Switch to the Android tab for launcher densities from mdpi to xxxhdpi plus the Play Store icon.

Why there are so many

Each context renders the icon at a different point size, and each device renders at 2x or 3x. Multiply those together and a universal app needs well over a dozen renderings. Xcode will happily build with slots missing and then fail validation at upload, which is why a checklist beats memory.

No transparency, no pre-rounded corners

iOS applies the rounded-rectangle mask itself. Supplying an icon with transparent corners produces black wedges once the system mask is applied, and pre-rounding your own corners produces a visible double-rounded edge. Always deliver a full-bleed opaque square.

The 1024px icon is the one people judge

It is the only icon a potential user sees before installing, sitting at the top of your store listing next to the name. It is also the only one that is never masked down to thumbnail size, so it rewards detail that would be wasted elsewhere — while still needing to survive the 40px rendering once installed.

How to use the ios app icon sizes

Pick the idiom you are shipping — iPhone, iPad, App Store, or Android.
Work down the list and confirm you have an asset for every required size.
Export each size from the 1024px source rather than upscaling a smaller file.
Check the smallest sizes visually — Settings and notification icons are where detail disappears.
Export the checklist and tick it off before you submit, since Xcode builds fine with slots missing.
