About ads on the Display Network

The Display Network plays host to a huge variety of ad formats and sizes. Some sizes and formats perform better than others, and it's best to experiment with multiple ad types and messages. Bear in mind that your ads are eligible to appear on mobile devices by default, so this article covers information about mobile Display ads too.

Image ads on the Display Network

Image ads on mobile devices are similar to normal image ads that you'd see on a desktop computer, but they can link to your mobile website or to your app. To have your image ads run on mobile devices, just make sure that your campaign is opted in to the Display Network. Every image size that is accepted for ads on running desktop computers is also accepted for ads on mobile devices. However, to run ads on mobile apps and websites that are designed for mobile devices, your image ad size should be 320 x 50. Image ads can show as banner ads or interstitials in mobile apps – you can find the recommended sizes for each, below.

Interstitial image ads

These are full-screen ads that tend to have higher click-through rates than banner ads, but may have a higher CPC. These appear as someone moves between screens or pages in an app.

  • Sizes for mobile phones: 300 x 250, 320 x 480 and 480 x 320.
  • Sizes for tablets: 1024 x 768 and 768 x 1024.

Banner image ads

Banner ads appear as a small strip or “banner” across the top of an app page or screen. They’re the most commonly used ad format for mobile. You can upload double-sized images (for example, a 640 x 100 image for a 320 x 50 ad slot) for high-resolution display devices. We’ll auto-adjust the image based on the device’s pixel density.

  • Sizes for mobile phones and tablets: 320 x 50, 468 x 60, 728 x 90 and 300 x 250.


By default, your ads will show both as banners and interstitials. If you only want to run interstitials, go to the Display Network tab in AdWords and click + Exclusion under “Campaign exclusions”. Select “GMob mobile app non-interstitial” to exclude banner ads from your mobile app campaign.
