You work for an agency and you need to upload image assets to your customer’s app campaign. What aspect ratios should you use?

Google Ads app campaigns support a variety of image asset aspect ratios to ensure optimal display across different placements. The recommended aspect ratios are 1:1 (square), 1.91:1 (landscape), and 4:5 (portrait). These ratios cover the most common display formats on mobile devices and across Google's network, maximizing visibility and engagement for your app campaign. Using these specific ratios helps your ads adapt seamlessly to various ad slots, from in-app placements to Google Search and Display Network. Other options include incorrect or incomplete sets of supported aspect ratios, which would limit your ad's reach and effectiveness.
