Complete Guide to App Icon Sizes for All Platforms

Creating app icons for multiple platforms can be overwhelming. Each platform has specific requirements for icon dimensions, and missing even one size can cause your app to display incorrectly. This comprehensive guide covers all the icon sizes you need for iOS, Android, macOS, Windows, web, and more.

Why App Icon Sizes Matter

App icons are displayed in many different contexts across devices - from tiny 16x16 pixel favicons in browser tabs to large 1024x1024 pixel images in app stores. Each context requires a specific size to ensure your icon looks crisp and professional.

Using incorrectly sized icons can result in blurry images, distorted proportions, or rejected app submissions. Platform guidelines are strict about icon dimensions, and meeting these requirements is essential for app store approval.

The good news is that with a high-quality source image (we recommend starting with 1024x1024 pixels), you can automatically generate all the sizes you need using our free app icon generator.

iOS (iPhone & iPad) Icon Sizes

Important Notes for iOS (iPhone & iPad)

  • Always start with a 1024x1024 pixel source image for best quality

Android (Google Play) Icon Sizes

Android uses density-independent pixels (dp) with multiple density buckets for different screen densities.

Icon Design Best Practices

Start Large

Always design at 1024x1024 pixels or larger. This ensures you have enough detail to scale down without losing quality.

Keep It Simple

Complex details get lost at smaller sizes. Use bold shapes and limited colors for better recognition.

Test at All Sizes

Preview your icon at 16x16, 32x32, and 1024x1024 to ensure it looks good across all contexts.

Follow Platform Guidelines

Each platform has specific design guidelines. iOS prefers flat design while macOS allows more depth and shadows.

Generate All Icon Sizes Automatically

Skip the manual resizing. Upload one image and get all the sizes you need for any platform.
