App Icon Size for Windows App (MSIX)
Windows 11 · Microsoft Store
The complete, up-to-date icon size requirements for Windows App (MSIX) in 2026. Every pixel dimension for Microsoft Store — plus format requirements and common mistakes.
Windows App (MSIX) icons require multiple sizes to ensure optimal display across Windows 11's various UI contexts, from taskbars to Start menu tiles. The 256x256 pixel size serves as the master icon, providing the highest detail for large displays and scaling down to smaller variants. Windows Store apps uniquely need both square and plate (wide tile) variants to support different tile layouts in the Start menu. The ICO format bundles all sizes efficiently, while PNG offers individual size control. Proper sizing ensures crisp rendering across high-DPI displays and different system zoom levels, critical for professional app presentation.

Common Mistakes for Windows App (MSIX) Icons
Three common mistakes plague Windows App (MSIX) icon preparation: First, developers often skip creating true 16x16 and 24x24 pixel versions, relying on automatic scaling that produces blurry results in system tray and file explorer contexts. Second, many forget to create wide tile (plate) variants, missing opportunities for prominent Start menu placement. Third, developers frequently use non-square aspect ratios or add padding to icons, causing misalignment in Windows 11's rounded square icon containers. These oversights result in unprofessional appearance and reduced discoverability in the Microsoft Store interface.
