App Screen Sizes

App screen sizes​

Windows​

Overwolf apps should act like native desktop applications and not like a website. Make sure you implement our best practices for using windows before implementing your own app to avoid basic mistakes. Focusing on a good desktop experience improves your app’s behavior and user experience.

Overwolf apps function as desktop applications and should prioritize clear and useful information within a compact layout that isn’t always full-screen. Moreover, app developers should design with ad integration in mind in order to save time and effort redesigning the app later on.

Overwolf App Screen Size and UX Recommendations​

Consider Popular Resolutions and design your app for the most popular screen resolutions:

  • 1920x1080 (1080p, FHD)—the majority of users use this resolution.
  • 2560x1440 (1440p, QHD)—the second most popular choice, though less common.
  • 1366x768 (HD) and 3840x2160 (4K UHD)—used by a smaller portion of users.
  • 3440x1440 (UltraWide QHD) and other resolutions (e.g., 1920x1200, 1600x900, 2560x1600)—used by a very small percentage (~1%) of users.

Set an Optimal Default Window Size​

Avoid launching apps on full screen unless this was set by the user. Things to consider:

  • Design for smaller screens—ensure the default window size is compatible with smaller, popular screen sizes (e.g., 15” and 13” screens and 1280x720 or 1440x900.
  • Allow resizing—users should be able to dynamically resize the app to their preferred dimensions.
  • Use a 16:9 aspect ratio—this is the optimal ratio for most screens. A good default screen size example is 1300x730 px.

In-Game Overlay Behavior​

  • Keep sticky overlay elements non-intrusive and avoid covering key game HUD areas.
  • Allow users to adjust overlay positioning and, if possible, size per their preferences
    • but avoid opening the in-game screen in full size.
    • and on secondary monitors, as users often cover or close full-screen apps on a second monitor.
  • Ensure hotkeys and interactions work seamlessly across different screen setups.
