How to get Audience Network right
Design it right
Audience Network extends Meta ads into third-party apps and sites as native, banner, interstitial and rewarded formats. That range means it accepts several ratios: a full-screen 9:16 at 1080 x 1920 covers the interstitial and rewarded-video slots that tend to perform best, while 1.91:1 and 1:1 cover native and banner units. The practical takeaway is that a vertical master gives you the strongest Audience Network coverage, with a square or landscape file backing up the smaller units.
The common mistake
The thing to watch is that Audience Network serves outside Meta's own apps, so the surrounding context varies and quality control matters more - a creative that reads clearly on its own, without relying on Facebook's chrome, performs better. Both image and video run, up to the standard Meta limits. Many advertisers leave Audience Network on through automatic placements without ever supplying a fitting ratio; adding a 9:16 cut is the single change that makes this placement look intentional rather than padded.
Check your creative against Audience Network
Drop your files into the free creative validator - it reads each file's dimensions in your browser, tells you which placements it covers, and flags the aspect ratio your set is missing. For a single file, the aspect ratio checker gives a per-placement verdict.
