YouTube Shorts launched in 2021 as YouTube's answer to TikTok and Instagram Reels. It's now one of the highest-traffic short video feeds in the world, with over 70 billion daily views. For creators already making TikToks or Reels, Shorts is a free distribution channel that requires almost no extra work.
YouTube Shorts requirements (2026)
- Aspect ratio: 9:16 vertical (mandatory for the Shorts feed)
- Resolution: 1080×1920 pixels (1080p vertical)
- Duration: up to 3 minutes (extended from 60 seconds in 2024)
- Format: MP4 H.264 recommended
- File size: no practical limit (256GB technically)
If you upload a horizontal or square video with #Shorts in the title, YouTube may still place it in the Shorts feed, but it will have black bars and perform significantly worse.
Cross-posting: Shorts, Reels, and TikTok
The 9:16 format at 1080×1920 is identical across YouTube Shorts, Instagram Reels, and TikTok. If you're creating content for one, you can cross-post to all three with minimal effort. The key rules:
- Remove TikTok watermark before posting to YouTube or Instagram. Both platforms detect and deprioritize TikTok-watermarked content.
- Remove Instagram watermark before posting to YouTube or TikTok.
- YouTube Shorts allows up to 3 minutes, TikTok up to 10 minutes, Reels up to 15 minutes, so the same clip works everywhere.
The Shorts algorithm
YouTube Shorts uses a different algorithm than regular YouTube videos. The key metrics are: swipe-away rate (how quickly people skip your Short), completion rate (what percentage watch to the end), and rewatch rate. A 30-second Short watched fully outperforms a 3-minute Short watched halfway. Start with your best moment, not a slow intro.
Shorts vs regular YouTube videos
Shorts and regular videos are distributed through completely separate systems. A Short will not appear in regular YouTube search or recommendations as a regular video. But Shorts can drive subscribers who then watch your regular videos. Many creators use Shorts as a top-of-funnel to grow their channel.
What are the best video settings for YouTube Shorts?
- ✓Hook viewers in the first second. YouTube measures how long people watch before swiping.
- ✓Record at 1080×1920 (vertical). Horizontal footage with black bars performs worse in the Shorts feed.
- ✓Keep Shorts under 60 seconds for maximum algorithmic reach. Longer Shorts get less distribution.
- ✓Remove TikTok or Instagram watermarks before cross-posting. YouTube deprioritizes watermarked content.
- ✓Upload between 6-9 PM local time for maximum initial views in the first 24 hours.
Why compress video before sending on YouTube Shorts?
YouTube Shorts enforces a strict file size limit. If your video exceeds it, YouTube Shorts will either reject the upload, reduce quality automatically, or convert it to a document file that recipients must download manually.
By compressing with CompressYourVideo.combefore uploading, you control the quality. Our tool calculates the optimal bitrate for your specific video length, so you get the sharpest possible result within the platform's limit.
