YouTube Shorts Dimensions — 1080x1920, Safe Zone & Length Limit

The Shorts Safe Zone

Every guide will hand you a confident pixel count for the Shorts safe zone. None of them can source it. Google does not publish safe-zone margins for Shorts — it ships downloadable transparent PNG templates alongside its video ad specs and tells you to keep your logo, product, and supers inside the red area. The numbers you have read elsewhere are people measuring those PNGs, and they disagree with each other.

So here is the useful answer instead. Meta does publish percentages for its 9:16 frame — 14% off the top, 35% off the bottom, and 6% off each side — and they are the strictest published margins in short-form video. Applied to a 1080x1920 canvas they leave 950x979px, and they comfortably clear the Shorts interface. Design inside that box and one export is safe everywhere.

• Full-bleed video, centred text: the footage should still fill all 1080x1920. Only the readable elements need to respect the box.
• Titles are longer than you think: a Short’s title wraps to two lines on a narrow phone, pushing the description and channel row further up the frame. Budget for the worst case, not your test device.
• Burned-in captions are the classic mistake: subtitles placed “near the bottom” in your editor land squarely behind YouTube’s own title and description.
• Grab Google’s template: if you want the literal red safe area, download the vertical PNG from Google’s video ad specs and drop it on a layer above your timeline. That is the only authoritative version of it.

Shorts vs. TikTok vs. Instagram Reels

One 1080x1920 export covers all three. What differs is the interface drawn on top, how long the video may run, and — revealingly — how much each platform is willing to tell you.

The practical takeaway is the safe-zone row. Only Meta commits to numbers, its numbers are the strictest, and they clear the Shorts and TikTok interfaces with room left over. Build to the Reels safe zone and post the same file to TikTok and Shorts without reopening your editor.

How to Turn a Landscape Video Into a Short

You have exactly two honest options: crop to 9:16 and lose the sides, or pad to 9:16 and fill the gap. Both produce a vertical file, so both are eligible. Only one of them looks good on a phone.

ffmpeg -i input.mp4 -vf "crop=ih*9/16:ih,scale=1080:1920:flags=lanczos" \
  -c:a copy short.mp4

ffmpeg -i input.mp4 -filter_complex \
  "[0:v]scale=1080:1920:force_original_aspect_ratio=increase,crop=1080:1920,boxblur=40:1[bg]; \
   [0:v]scale=1080:-2[fg];[bg][fg]overlay=(W-w)/2:(H-h)/2" \
  -c:a copy short.mp4

You Cannot Upload a Shorts Thumbnail

If you came here looking for the Shorts thumbnail size, there isn’t one. YouTube does not let you upload a custom thumbnail for a Short the way you can for a long-form video. You choose a frame from the Short itself, and that frame becomes what appears in search, on hashtag and audio pages, and on your channel grid.

• The choice is permanent: once selected, the thumbnail cannot be changed after upload. There is no second attempt.
• Shoot the thumbnail: because the cover must be a frame, plan one. Hold a clean, well-lit beat somewhere in the Short with your subject centred and no motion blur.
• The channel grid crops it: your Short’s frame is displayed as a tall tile on your channel, not a full 9:16 frame. Keep the subject away from the very top and bottom of the frame you pick.
• 1280x720 is not the answer: that is the long-form YouTube thumbnail size — 16:9, uploadable, replaceable. None of that applies to a Short.
