Which aspect ratios are accepted for image assets in app campaigns?

Analysis of Correct Answer(s)

For Google Ads App campaigns, providing a variety of asset dimensions is crucial for maximizing reach and ad performance. Google's system uses these assets to create ads automatically for different placements and formats. The three accepted aspect ratios for image assets are:

• 1:1 (Square): A versatile format that fits well in native ad slots, carousels, and in-feed placements.
• 1.91:1 (Landscape): A standard landscape format, commonly used for banner ads and in-feed content on the Google Display Network and YouTube.
• 4:5 (Portrait): A vertical format optimized for mobile-first, full-screen experiences, such as ads in feeds on YouTube and Discover.

Submitting all three ensures your ads are eligible to compete for inventory across all available properties, including Google Search, Play, YouTube, and the Display Network.

Analysis of Incorrect Options

The other choices are incorrect because they either omit a required aspect ratio or include an unsupported one.

• Options that only list two of the three correct ratios (e.g., 1:1 and 1.91:1 only) are incomplete. Omitting the 4:5 ratio would limit your ad's eligibility for key vertical mobile placements.
• Options that include 1.75:1 are incorrect. While other campaign types might use different ratios, this is not a standard accepted aspect ratio for App campaign image assets.
