App Icon Size for macOS Sonoma
macOS 14 · Mac App Store / Direct
The complete, up-to-date icon size requirements for macOS Sonoma in 2026. Every pixel dimension for Mac App Store / Direct — plus format requirements and common mistakes.
macOS Sonoma requires app icons in seven specific sizes: 16x16, 32x32, 64x64, 128x128, 256x256, 512x512, and 1024x1024 pixels. The 1024x1024 master icon serves as the foundation for all other sizes and appears prominently in the Mac App Store. Icons must be packaged in ICNS format for distribution, though individual PNG files are used during development. macOS automatically scales icons contextually, displaying larger sizes in Finder, Dock, and App Store while using smaller versions for menu bars and system dialogs. High-resolution displays demand pixel-perfect clarity at every scale.

Common Mistakes for macOS Sonoma Icons
Common mistakes include designing only the 1024x1024 size without optimizing smaller variants, causing illegible details at 16x16 and 32x32 pixels. Many developers forget to remove transparency or shadows since macOS applies its own visual effects. Another frequent error is using JPEG compression or incorrect color profiles instead of PNG with sRGB colorspace. Developers often skip testing how icons appear in dark mode or fail to ensure sufficient contrast at 64x64 and 128x128 sizes where icons frequently display in system interfaces.
