App Icon Size for Apple Watch Ultra 2
watchOS 10 · App Store Connect
The complete, up-to-date icon size requirements for Apple Watch Ultra 2 in 2026. Every pixel dimension for App Store Connect — plus format requirements and common mistakes.
Apple Watch Ultra 2's 49mm case requires the largest watchOS icon set, with the 1024px master icon being critical for App Store Connect submission. The 100px and 88px sizes appear prominently in the Watch app on iPhone, while 58px, 55px, and 44px sizes display on the watch face itself. The Ultra 2's expansive screen real estate means your icon details remain visible even at smaller sizes. Unlike iPhone icons, watchOS icons must be PNG format without alpha transparency. The larger target sizes (100px, 88px) are particularly important as they're the primary discovery points for users browsing watch apps on their iPhone.

Common Mistakes for Apple Watch Ultra 2 Icons
Common mistakes include submitting icons with alpha channels (watchOS requires solid backgrounds), using overly complex designs that become illegible at 29px and 40px sizes, and failing to optimize the 1024px master icon which App Store Connect uses for processing all smaller variants. Many developers also neglect the 100px size despite it being highly visible in the iPhone Watch app's browse interface. Another frequent error is designing primarily for smaller Apple Watch models, resulting in icons that don't leverage the Ultra 2's superior screen clarity and larger display targets.
