Audience Network places Meta ads inside third-party apps and mobile sites rather than on Facebook or Instagram. Meta documents a 9:16 ratio with a minimum of 398×208 pixels and a 30MB ceiling, and states that the same specs apply across all three formats: native, banner and interstitial.
- •Design for a slot you do not control — host apps render native ads in their own styling.
- •Supply well above the 398×208 minimum; it is a floor, not a target.
- •The same creative covers native, banner and interstitial — Meta applies one spec to all three.
What you need to know
Audience Network is the placement most advertisers forget they are buying. It extends a Meta campaign into third-party apps and mobile websites, which means the creative is rendered by someone else's app in a slot you do not control — the reason Meta's guidance here is looser than for Feed or Stories.
The three formats differ in how they appear rather than in what they accept. Native ads are styled by the host app to blend with its own content; banner ads sit in a fixed strip at the top or bottom of the screen; interstitials take over the full screen between actions. Meta states the technical specs are the same across all three.
Meta's own documentation is internally inconsistent here, and it is worth knowing: the guide gives a 9:16 ratio alongside a 398×208 minimum, which is a landscape shape rather than a vertical one. The safe reading is that 398×208 is a floor inherited from the banner format while 9:16 describes the full-screen interstitial. Supply a 9:16 asset comfortably above the minimum and both are satisfied.
