The master app icon is 1024 × 1024 px (1:1). iOS requires this exact size for App Store submission. Android Play Store requires 512 × 512 px.
App icons are the first impression of your app on iOS and Android home screens. Apple and Google both require specific master sizes that they downscale for every surface — here are the 2026 requirements.
| Asset | Dimensions | Ratio | Format | Max size |
|---|---|---|---|---|
| iOS App Store | 1024 × 1024 | 1:1 | PNG (no alpha) | 1 MB |
| iPhone Home Screen | 180 × 180 | 1:1 | PNG | 500 KB |
| iPad Home Screen | 167 × 167 | 1:1 | PNG | 500 KB |
| Google Play Store | 512 × 512 | 1:1 | PNG (32-bit) | 1 MB |
| Android Adaptive Icon | 432 × 432 | 1:1 | PNG | 500 KB |
| Google Play Feature Graphic | 1024 × 500 | 2.05:1 | JPG / PNG | 1 MB |
Pro tip: Design at 1024 × 1024 with no transparency and no rounded corners. iOS and Android both apply their own rounded-corner mask automatically — if you round them yourself, the icon gets double-rounded.

Designing an App Icon That Scales
App icons are shown at wildly different sizes — from 1024 × 1024 in the App Store to 60 × 60 in Notification Center. Design at 1024 × 1024 with a single bold shape, high contrast, and no fine detail. If the icon isn't recognizable at 60 × 60, simplify it further.
Common mistakes to avoid
- Adding rounded corners yourself — iOS and Android double-round them.
- Using transparency on iOS icons — Apple rejects them at submission.
- Fine detail that disappears at 60 × 60.
Frequently asked questions
What size is an app icon in 2026?
Master app icons are 1024 × 1024 px (1:1). iOS App Store requires this exact size; Android Play Store requires 512 × 512 px.
Should my app icon have rounded corners?
No. Design a square icon with no rounded corners. iOS and Android both apply their own rounded-corner mask.
Does an iOS app icon need transparency?
No. iOS rejects app icons with any alpha channel. Export as flat PNG without transparency.
What is an Android adaptive icon?
An adaptive icon is a 432 × 432 px foreground layer that Android composites over a background layer. This lets Android crop the icon into different shapes on different devices.
What size is the Google Play feature graphic?
1024 × 500 px (2.05:1). This is the banner at the top of your Play Store listing.
JPG or PNG for app icons?
PNG. Both iOS and Android require PNG format for app icons.
