Every time I ship an iOS app I end up re-looking-up the icon sizes, so here's the complete 2026 reference in one place — plus the part nobody tells you up front.
App Store
- 1024×1024 px — the required master. With a modern Xcode project this is often the only size you need to provide (see the shortcut below).
iPhone
| Use | Points | @2x | @3x |
|---|---|---|---|
| Home Screen | 60pt | 120×120 | 180×180 |
| Spotlight | 40pt | 80×80 | 120×120 |
| Settings | 29pt | 58×58 | 87×87 |
| Notifications | 20pt | 40×40 | 60×60 |
iPad
| Use | Points | @2x |
|---|---|---|
| Home Screen | 76pt | 152×152 |
| iPad Pro Home | 83.5pt | 167×167 |
| Spotlight | 40pt | 80×80 |
| Settings | 29pt | 58×58 |
| Notifications | 20pt | 40×40 |
Rules: square PNG, no transparency/alpha, and no rounded corners (iOS masks them automatically).
The shortcut nobody mentions
Since Xcode 14 you can drop a single 1024×1024 PNG into a "Single Size" AppIcon.appiconset and Xcode generates every other size at build time. You rarely need the full legacy set anymore — but it's still there if you want pixel-perfect control per size.
iOS 18 / iOS 26 dark + tinted icons
Newer iOS also supports dark and tinted icon variants (and the "Liquid Glass" look in iOS 26). You add extra 1024×1024 variants in the asset catalog and iOS handles the rest.

Disclosure: I build IconBundlr, an AI app-icon maker that generates an icon from a text prompt and exports the whole AppIcon.appiconset. I basically turned the reference above into a tool — but the table's the table, so copy it wherever you need it.
