All Seenspire feeds are designed to be fully responsive: the content will adapt automatically to your screen size and orientation. 

Seenspire supports all common aspect ratios: 16:9, 9:16, 4:3 and 1:1.

For Social content that is shown using our Grid layout, we have an extra option where you can select the 21:9 aspect ratio, to create an extra zone for content.
