ShortsAIYouTube Shorts length, dimensions and aspect ratio
Maximum length: 3 minutes. Any vertical or square video up to 3 minutes uploaded on or after 15 October 2024 is a Short.
Aspect ratio: 9:16 vertical or 1:1 square. A 16:9 video is never a Short, whatever its length.
Recommended size: 1080 by 1920 pixels, MP4, H.264. Maximum playback resolution for Shorts is 1080p.
How long can a YouTube Short be?
Up to 3 minutes. YouTube raised the limit from 60 seconds on 15 October 2024: any video with a square or vertical aspect ratio and a length of 3 minutes or less uploaded on or after that date is categorised as a Short. Videos uploaded before that date kept the old 60-second rule. There is no separate minimum; a 5-second vertical video is still a Short.
What aspect ratio and dimensions do Shorts need?
Vertical 9:16 or square 1:1. The recommended export is 1080 by 1920 pixels for 9:16, or 1080 by 1080 for square. Shorts play at a maximum of 1080p, so a 4K vertical upload is downscaled and gains nothing except upload time. Anything wider than square, including 4:5, is classified as a regular video.
What gets a vertical video treated as long-form by mistake?
- Length over 3 minutes by even a second. Trim to 2:59 or shorter.
- A 16:9 or 4:5 frame, including a vertical video padded with landscape bars.
- Metadata is not the deciding factor: the #Shorts hashtag helps discovery but does not classify the video. Aspect ratio and length do.
Where is the safe zone for text and captions?
The Shorts player overlays the title, channel name, description and the like/comment/share column over the bottom and right of the frame. Keep captions and any on-screen text in the middle band, roughly the central 60 percent of the height, and away from the right edge. ShortsAI places burned-in subtitles in that band by default.
Can Shorts be monetised?
Yes, through the YouTube Partner Program with Shorts-specific thresholds that differ from long-form. Those thresholds change periodically; check YouTube's current Partner Program page rather than a third-party summary before planning around them.
How does this affect clips made with ShortsAI?
The clipper exports 9:16 at 1080 by 1920 with clips of 15 to 60 seconds, so every clip is inside the Shorts rules without settings changes. If you cut a longer clip by hand in the editor, keep it under 3 minutes.
Common questions
- Can a YouTube Short be 5 minutes?
- No. The limit is 3 minutes. A 5-minute vertical video uploads fine but is treated as a regular video, not a Short.
- What size is a YouTube Short?
- 1080 by 1920 pixels in 9:16, or 1080 by 1080 in 1:1. Maximum playback resolution is 1080p.
- Does a Short need the #Shorts hashtag?
- No. Aspect ratio and length decide classification; the hashtag only helps discovery.
