What is the aspect ratio for Facebook right column images and videos?

The aspect ratio for Facebook right column images and videos is indeed 1.91:1. This specific ratio is optimized for the Facebook platform, particularly for its advertising formats, ensuring that creatives display properly across the varied formats and devices used by audience members. This size accommodates both visual clarity and engagement, which are crucial in advertising.

When creating ads for the right column, adhering to this aspect ratio allows marketers to produce images and videos that fill the allocated space effectively without being cropped or distorted. Multimedia presented in this ratio is more likely to capture user attention, as it fits seamlessly within the platform's design.

While other aspect ratios like 9:16, 4:5, and 16:9 are valid for different types of posts or ads on Facebook and other platforms, they do not apply specifically to the right column format where 1.91:1 is necessary for optimal presentation and performance in that advertising slot.
