Images, and game asset sizes

We have some general sizes for desktop and mobile, but keep in mind that the final dimensions depend on the pixels provided by the designer for each image and can be adjusted directly within the platform. Because of this, we cannot provide exact sizes—it depends on your files. You can get a general idea from your Customer Success (CS) team based on the files you already have. If images appear low quality, it is usually because they don’t have the correct resolution.

Here are some standard measurements that can be used:

• Desktop background: 2496 × 1404 px

Keep in mind that the image will scale up or down depending on the device (computer, tablet, or phone). We recommend using a larger size so it looks its best. However, avoid placing specific figures or elements directly on the background. Instead, add them as separate images on top, which can then be sized correctly—otherwise, they won’t align one-to-one with the other campaign elements.

• Mobile background: 1098 × 494 px

Images can always be adjusted to match the exact size a designer has created, which is why we cannot give a precise number for every case.

FYI: For drop, shooter, or reel games, we recommend using images of the same size to ensure the best visual appearance in the game.
