What is the recommended aspect ratio for TikTok ads?

The recommended aspect ratio for TikTok ads is 9:16 (vertical). This aspect ratio is specifically optimized for mobile viewing, which is crucial for a platform like TikTok, where content is primarily viewed on smartphones. Using vertical video ensures that the ad occupies the full screen, providing an immersive experience that captures the attention of viewers more effectively.

Aligning with the platform's design encourages engagement as users are accustomed to scrolling through vertically oriented content. This aspect ratio also leverages the unique features of TikTok’s interface, allowing for better interaction and visibility compared to horizontal or square formats, which do not utilize the screen space as effectively in a mobile-first environment. Consequently, using 9:16 enhances the likelihood of the ad being viewed and engaged with, which is a key objective in any media buying strategy on TikTok.
