Important note: This article is about infeed, the placement inside of content or feed.

  • For mobile fullscreen, we use 640x1280 as the creative size. Then the ad will scale itself to the perfect size to fit the placement. Read more about mobile fullscreen types: mobile interstitial and mobile expandable.

  • For in-stream ads, we create 8 different sizes to fit the ad for the user's device. Read more about in-stream.

Now, let's talk about the most used infeed placement sizes.

TLDR

The most popular sizes are:

  1. 300 x 250 px

  2. 300 x 600 px

  3. 728 x 90 px

  4. 160 x 600 px

  5. 120 x 600 px
