Make a square tweet video

Square is the ratio that survives everywhere. Instagram, Facebook and LinkedIn all show 1:1 in full in the feed, while a 9:16 vertical gets cropped or letterboxed depending on the surface. If one file has to work in several places, this is it.

The card keeps the author's name, handle and timestamp so your export credits them. The post itself still belongs to whoever wrote it, so check you have the right to reuse it before you publish.

1080 by 1080 also encodes quickly and stays small, because it is roughly half the pixels of a 1080 by 1920 vertical. That matters when the render is happening on a phone.

Questions

Is square or vertical better for video?
Vertical wins on Reels, TikTok and Shorts. Square is safer for ordinary feed posts and for one file used in several places.
What size is a square video?
1080 by 1080 pixels. Every major platform accepts it and shows it uncropped in the feed.
Why is the padding larger on this page?
Feed thumbnails crop your square again, so extra margin keeps the tweet text away from where that crop lands.
