Aspect ratio

The width-to-height ratio of a video frame.

Three aspect ratios dominate: 16:9 (horizontal long-form), 9:16 (vertical short-form), and 1:1 (square, mostly legacy).

Each platform favors a specific ratio. Cross-posting requires reformatting, not just re-uploading.

Choosing the wrong aspect ratio for a platform meaningfully depresses both CTR and retention.

Why it matters

Treat aspect ratio as a platform-specific decision, not a global default.
