YouTube Shorts Dimensions
The standard YouTube Shorts size is 1080 × 1920 pixels at a 9:16 aspect ratio. This is the same canvas as Instagram Reels and TikTok, so vertical video produced once can be cross-posted across all three without resizing. Square (1:1) videos technically qualify as Shorts but lose 30% of the screen to black bars and rarely surface in the Shorts shelf.
What Makes a Video a Short
YouTube uses three criteria to classify a video as a Short:
- Aspect ratio: 9:16 vertical (or square 1:1)
- Duration: 60 seconds or less (3 minutes rolling out)
- Tag:
#Shortsin the title or description
Miss any one of these and the video gets treated as a regular upload, which means it shows up in the regular feed and search instead of the high-volume Shorts shelf. The Shorts shelf is where almost all algorithmic discovery happens.
Safe Zones
The Shorts player overlays UI on top of every video. These areas hide your content:
- Top ~210 px: channel name, search icon, more options menu
- Bottom ~270 px: video title, channel avatar, like / dislike / comment / share / remix buttons
- Right edge ~120 px: action button column when active
Keep all important content — text, faces, key visuals — inside the center 1080 × 1440 area. About 240 px clear top and 240 px clear bottom. This is similar to TikTok but slightly looser than Instagram Reels.
File Format & Codec
- Format: MP4 (recommended) or MOV
- Video codec: H.264 (or H.265 for higher efficiency)
- Audio codec: AAC, 48 kHz, 384 kbps stereo recommended
- Frame rate: 24, 30, or 60 fps (60 fps gets clearer motion for fast cuts)
- Bitrate (1080p): 8–12 Mbps for SDR, 12–15 Mbps for HDR
- Max file size: 256 GB or 12 hours (Shorts will be far smaller)
Cover Thumbnail
YouTube Shorts use 1080 × 1920 px for the cover thumbnail (same as the video). Note that the thumbnail does not appear in the Shorts feed because the video plays automatically. Where the thumbnail does show:
- Channel page Shorts tab
- Search results
- External shares (Twitter, embeds)
Place key visuals and text in the center 1080 × 1080 area so the thumbnail also works as a square crop on your channel page.
Tips for YouTube Shorts Performance
- Always export at exactly 1080 × 1920 — anything else loses Shorts shelf eligibility
- Add
#Shortsto title or description (still required despite YouTube's automatic detection) - Hook in the first 1–2 seconds — the Shorts shelf has zero patience
- Keep critical text in the center 1080 × 1440 safe zone
- Use 60 fps for any Short with motion or fast cuts (looks much smoother)
- Add captions or burn-in subtitles — many viewers watch muted
- Stay under 60 seconds unless you're approved for 3-minute Shorts
- Need to crop landscape footage? Use our resizer to convert to 9:16 cleanly.
Frequently Asked Questions
What is the YouTube Shorts size?
The YouTube Shorts size is 1080 × 1920 pixels at a 9:16 aspect ratio — vertical, full-screen on a phone. This is the same canvas used by Instagram Reels and TikTok, so vertical video can be re-uploaded across all three with no resizing.
What is the YouTube Shorts aspect ratio?
YouTube Shorts use a 9:16 vertical aspect ratio. Square (1:1) videos technically work but display with black bars top and bottom and lose discovery in the Shorts shelf. Always export at 9:16.
How long can a YouTube Short be?
YouTube Shorts can be up to 60 seconds long, with 3-minute Shorts now rolling out to all creators. Anything longer is treated as a standard video upload, which means it shows in the regular feed instead of the Shorts shelf.
How does YouTube decide if a video is a Short?
YouTube classifies a video as a Short if all three are true: aspect ratio is 9:16 (or square), duration is 60 seconds or less (or up to 3 min for eligible creators), and the title or description includes "#Shorts". Missing any one and YouTube treats it as a normal upload.
What is the maximum file size for a YouTube Short?
YouTube Shorts inherit the standard YouTube limit of 256 GB or 12 hours per file. In practice, a 60-second 1080p Short rarely exceeds 200 MB. Use H.264 video codec at 8–12 Mbps bitrate for clean motion.
Where is the safe zone on a YouTube Short?
Avoid the top ~210 px (channel name, more options menu) and the bottom ~270 px (title, like / dislike / comment / share buttons, channel avatar). Keep all important content in the center 1080 × 1440 area.
Can I upload a horizontal video as a YouTube Short?
Technically yes, but YouTube will pillarbox it with black bars and the Short will not be eligible for the Shorts shelf, killing reach. Always shoot vertical or convert horizontal footage to 1080 × 1920 before uploading.
What thumbnail size do I need for a YouTube Short?
YouTube Shorts use 1080 × 1920 px (9:16) for the cover thumbnail — same as the video itself. Note that Shorts thumbnails do not show in the Shorts feed (the video plays directly), but they do show on your channel page and search results.
