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.

    To ensure you app is ad policy compliant, the minimum resizing of your app's window shouldn't be smaller than the ad container.

  • Use a 16:9 aspect ratio—this is the optimal ratio for most screens. Overwolf recommends a default screen size of 1300x840px to allow for optimal ad layouts.

In-Game Overlay Behavior​

  • Keep sticky overlay elements non-intrusive and avoid covering key game HUD areas.
  • Allow users to adjust overlay positioning and allow for resizing.
  • Avoid opening the in-game screen in full size on the main or on a second screen. Users often cover or close full-screen apps on a second monitor.
  • Ensure hotkeys and interactions work seamlessly across different screen setups.
