What are YouTube Shorts?
YouTube Shorts are vertical short-form videos up to 60 seconds long, displayed in a dedicated Shorts shelf on YouTube's homepage, mobile app, and channel pages. The format is 1080 × 1920 px vertical, the same as TikTok and Reels — which makes Shorts the natural cross-post for short-form video content. While Shorts plays automatically in the Shorts feed (so an in-feed thumbnail matters less), the cover image still drives clicks from search, from the YouTube homepage carousel, and from a channel's Shorts grid.
For US creators, YouTube Shorts is now a serious traffic source — over 70 billion daily Shorts views globally, with the algorithm capable of putting brand-new accounts in front of millions. Unlike the main YouTube feed, Shorts rewards volume and consistency. A creator posting 1 Short per day will almost always outperform one posting 1 Short per week, even if quality is comparable. That makes batch production critical — and batched production is where AI-assisted cover design saves hours per week.
How to create YouTube Shorts Covers with publy.ch
With publy.ch you produce Shorts covers as part of a batch workflow:
- Open the Shorts cover template — 1080 × 1920 vertical with the YouTube Shorts safe zone overlay.
- Drop in a video still — auto-cropped and color-corrected for thumbnail use.
- Generate the hook headline — the AI proposes 3–5 word headlines that read clearly at Shorts shelf size.
- Apply the brand kit — brand color accent, logo, brand font for the headline.
- Export at 1080×1920 — upload as a custom cover when publishing the Short via YouTube Studio.
You can batch 5–10 Shorts covers in a single session, which makes daily Shorts realistic for a one-person channel.
Best Practices for YouTube Shorts Covers
- Keep critical text in the top 65% of the frame. The bottom 35% is covered by title and channel info on the Shorts shelf.
- Match the cover to the first 3 seconds. Mismatched covers crash retention, which torpedoes reach.
- High contrast for mobile thumbnail size. Shorts shelf displays covers small — low-contrast designs disappear.
- One short headline. 3–5 words. The video does the rest.
- Brand a consistent visual identity for your Shorts grid. Same font, same color, same layout style — a Shorts grid is your channel's second storefront.
- Use a curiosity hook. "Wait for the end," "POV: you just…", "I had no idea" — TikTok-native hooks translate directly.
- Face on every cover that includes you. Even a small face is more clickable than no face.
- Don't recycle covers from TikTok 1:1. YouTube viewers expect slightly more polished design. Reuse the still, redo the cover.
Formats and Dimensions
- Cover size: 1080 × 1920 px (9:16 vertical)
- Shorts shelf display: roughly 240 × 426 px effective on mobile
- Safe zone for text: top 65% of frame
- File formats: JPG, PNG
- Maximum file size: 2 MB
- Headline font size: 80–140 px equivalent
Common Mistakes to Avoid
- Letting YouTube auto-pick a still. The auto-pick is usually a mid-motion blur.
- Text in the bottom third. It gets covered by title and CTA overlays on the Shorts shelf.
- Recycling YouTube thumbnails at 16:9. Shorts shelf needs vertical. Repurposing a landscape thumbnail leaves you with letterboxed black bars.
- No brand element. Without a visual signature, viewers don't remember which channel posted the Short.
- Vague hooks. "Daily vlog #47" earns no clicks. "I worked 16 hours and got nothing done" earns clicks.
