Short
Also known as: YouTube Short, Vertical short
Quick definition
A Short is a YouTube short-form vertical video, capped at 60 seconds, optimized for the dedicated Shorts feed. Shorts are YouTube's answer to TikTok and Instagram Reels — same vertical format, same algorithmic discovery model, but inside the YouTube ecosystem.

What is a YouTube Short?
A YouTube Short is a vertical 9:16 video up to 60 seconds long, uploaded as a Short via either the YouTube mobile app's Short creation flow or via the API with a #Shorts hashtag in the title or description. Shorts appear in a dedicated mobile feed (separate from the regular YouTube home feed) and on a Shorts shelf within channel pages. The format was launched globally in 2021 and has grown to multi-billion daily views.
Unlike traditional YouTube uploads which lean on subscriptions and search, Shorts are heavily algorithmic — viewers swipe through an infinite feed of recommended Shorts based on watch behaviour, much like TikTok's For You Page.
Shorts vs long-form YouTube
Two different mental models. Long-form YouTube uploads are searchable, evergreen, suited to tutorials and deep content; they drive subscriptions and watch-time monetization. Shorts are ephemeral discovery, suited to hooks and quick value; they drive subscribers indirectly when viewers click through to your channel from a viral Short. Most successful YouTube creators in 2026 publish both — Shorts for top-of-funnel discovery, long-form for deeper engagement and monetization. Shorts now contribute to channel monetization through a separate Shorts revenue pool.
Cross-posting Shorts, Reels, and TikTok
The core asset (a vertical 9:16 video, 15-60 seconds) cross-posts cleanly across all three platforms. Differences: TikTok prioritizes trending audio more aggressively; YouTube Shorts requires #Shorts hashtag for discovery; Instagram Reels rewards longer durations (up to 90 seconds) more than YouTube does. Per-platform tuning is mostly caption + hashtag adjustments, not media re-edits. Most creators publish the same MP4 to all three with varied captions.
Common pitfalls
- ×Forgetting #Shorts in the title or description — videos under 60 seconds without the tag may not be classified as Shorts
- ×Uploading horizontal video as a Short — it gets letterboxed and underperforms
- ×Going beyond 60 seconds — YouTube auto-rejects or downgrades to regular video
- ×Using copyrighted audio without YouTube's licensed library — risks demonetization or takedown
Tips
- ✓Cross-post the same video as Short, Reel, and TikTok — same media, three audiences, minimal extra effort
- ✓Title under 100 characters with #Shorts at the end — clean and discoverable
- ✓Use YouTube Shorts' built-in remix and audio library — algorithmic boost for licensed content
- ✓Publish 3-5 Shorts per week to feed the algorithm without burning out — consistency matters
Frequently asked questions
How long can a YouTube Short be?+
Up to 60 seconds. Videos longer than 60 seconds are classified as regular YouTube uploads and lose access to the Shorts feed.
Do Shorts count toward channel monetization?+
Yes. YouTube created a separate Shorts revenue pool in 2023 — eligible channels earn from Shorts views via shared ad revenue. Earnings per view are lower than long-form but at scale Shorts contribute meaningfully.
Can I upload Shorts via the YouTube API?+
Yes. Shorts use the standard YouTube Data API video upload endpoint with no special flag — YouTube auto-detects vertical 9:16 video under 60 seconds and classifies as a Short. The #Shorts hashtag in title or description is recommended for discoverability.
Are Shorts discoverable in YouTube search?+
Yes but the primary discovery surface is the Shorts feed itself. Shorts also surface in regular search results and the channel page Shorts shelf. Long-form videos still rank better for deep search queries.
