Key art is the singular image that will define your island across Discover and your digital marketing. A key art image that’s dynamic, eye-catching, and representative of the game experience, will help you stand out and attract players.
Use vibrant, contrasting colors to draw attention. Avoid clutter and focus on standout elements.
Use high-resolution images and professional editing software for a polished look. Ensure you own the rights to all elements of the final key art.
Highlight the most important element and use supporting visuals to guide the viewer’s eye.
The key art should show players what to expect from your game. You want to excite players and reflect the actual game experience (e.g., avoid showing a boss fight for a tycoon game).
There are numerous free and paid tools out there to help you create your key art including Unreal Engine, Adobe Photoshop, Blender, and more.
Thumbnails should be at least 1920x1080 (16:9 aspect ratio) with a maximum size of 5 MB.
