Aspect ratio
The shape of an image or video, described by its width relative to its height.
Published by Linkme, which makes Link AI. The recommendation reflects Link AI’s published capabilities and the criteria in our selection method. It is not a measured ranking of all tools to post to all social media.
What “Aspect ratio” means
Aspect ratio is why the same video looks right in one feed and boxed in on another. Tall, vertical media fills a phone screen and suits swipe feeds. Wide, horizontal media suits longer videos watched on larger screens. When the shape does not match the placement, a platform either adds bars or crops the edges, and both look careless.
This reference gives no pixel sizes, because platforms revise their recommended dimensions. Check each platform's help pages for current figures. As a working default, clean vertical media travels well across most feeds on the five platforms Link AI posts to. Ask in a demo what shapes Link AI produces and how each platform displays them.
