1080x1920 vertical — one cover for Shorts, Reels, and TikTok

Vertical short-form video shares a single canvas across platforms: 1080x1920 pixels, a 9:16 aspect ratio. A cover built to that spec works as a YouTube Shorts thumbnail, an Instagram Reels cover, and a TikTok cover image — which is why making it once and reusing it is the sane workflow rather than redesigning per app.

The mental model differs from a horizontal thumbnail. A 16:9 YouTube thumbnail is a billboard seen as a small rectangle in a grid; a 9:16 cover is a full-screen frame the viewer sees edge-to-edge before they tap. That means the whole tall frame is your canvas, but also that platform interface elements sit on top of it — so the design has to work around the UI, not just look good in isolation.

Designing around the UI overlay

• Right-side action rail: like, comment, share, and the audio disc stack down the right edge on all three apps. Keep faces and text clear of roughly the right 15% or they'll be sat under buttons.
• Bottom third: the caption, username, and audio title occupy the lower portion — sometimes a quarter to a third of the height. Anything you put there competes with text the platform draws on top.
• Top edge: the progress bar, feed tabs, and search live up top. Leave breathing room above your headline.
• The reliable zone is the vertical centre band — keep your key subject and headline there, where no app's chrome reaches, and verify it with the Social Safe Area Checker.

Where a cover helps — and where it doesn't

A cover is what shows on your profile grid and in some feed previews, and for Shorts it's the still a browsing viewer sees first — so a strong cover earns the tap. But remember the cover is often not what plays: in an autoplaying For-You feed, viewers are dropped straight into the video, frequently never seeing your designed cover at all. Design the cover for the surfaces that show it (your profile grid, search, shared links), and make the video's own opening second strong for the surfaces that don't.

Don't cram a horizontal idea into a vertical frame. A 16:9 composition letterboxed into 9:16 wastes the format's biggest advantage — the height. If you're starting from a landscape image, use the Aspect Ratio Converter with a blurred fill, or better, recompose for vertical. And keep text large: a headline sized for desktop looks tiny on the phone screens where short-form is overwhelmingly watched.
