YouTube Shorts Dimensions: Size, Specs and Safe Zone

The right YouTube Shorts dimensions are 1080 × 1920 pixels at a 9:16 aspect ratio, exported as an H.264 MP4. That fills the whole phone screen. YouTube treats any upload that is square or vertical and 3 minutes or shorter as a Short, and its help page says Shorts have "a maximum resolution of 1080p".

Most guides stop at the pixel size. This one also covers what YouTube does with other shapes, the real thumbnail size for Shorts (it is not 1280 × 720), and where the buttons sit on top of your video. Every spec was checked against YouTube's own help pages on 24 September 2026. When the file is ready, our Shorts scheduling guide picks up from upload to publish.

#Quick answer

• Dimensions: 1080 × 1920 px. YouTube says Shorts play at a maximum of 1080p.
• Aspect ratio: 9:16 is best. Any square or vertical ratio counts as a Short. 16:9 never does.
• Length: up to 3 minutes.
• Format: MP4 with H.264 video and AAC audio.
• Bitrate: 8 Mbps at 24 to 30 fps, 12 Mbps at 48 to 60 fps (YouTube's own numbers for 1080p).
• Max file size: 256 GB, the limit for every YouTube upload. A normal Short is under 300 MB.
• Thumbnail: 9:16, ideally 2160 × 3840 px. Custom images only in YouTube Studio on a computer, verified accounts only.
• Safe zone (approximate): keep text and faces 200 px from the top, 420 px from the bottom and 160 px from the right edge.

#YouTube Shorts dimensions and specs at a glance

A note on 1080 × 1920. YouTube does not publish a "recommended" pixel size for Shorts. It publishes the shape (square or vertical) and a ceiling (1080p). 1080 × 1920 is the biggest 9:16 frame at 1080p, and every phone and editor exports it. That is why it is the right answer.

A note on 4K. The 1080p line sits in YouTube's guide to making Shorts, and YouTube re-encodes everything you upload anyway. You can upload a 2160 × 3840 file and it will be accepted. It will just take longer to upload and process, and viewers will not see four times the detail. Export at 1080 × 1920 unless you have a reason not to.

#Which shapes become a Short (and what happens to 16:9)

YouTube does not have a "Short" checkbox. It decides from two things: the shape and the length. Since 15 October 2024, "any videos uploaded on or after this date with a square or vertical aspect ratio up to three minutes in length will be categorized as Shorts" (YouTube Help).

So "is 1920 × 1080 good for YouTube Shorts?" has a short answer: no. A horizontal file is a regular video, whatever its length. To turn it into a Short you have to reframe it to vertical first. The ffmpeg command further down does that in one line.

Also avoid adding black bars inside the file to fake a vertical frame. YouTube says padding "interferes with YouTube's ability to change the player dynamically to your video size" (YouTube Help: Video resolution and aspect ratios). Crop or reframe instead.

For every length rule, including what happens with music after one minute, see YouTube Shorts length.

#The YouTube Shorts safe zone, in pixels

YouTube puts its interface on top of your Short. The search and menu icons sit at the top. The like, comment and share buttons sit on the right. Your channel name, the Subscribe button, the title and the sound sit at the bottom. Anything under them is hard to see.

These numbers are approximate, not official. YouTube does not publish pixel margins for organic Shorts. Its Shorts editor shows "visual guides" when you drag text near a button, and white lines when text is too close to the edge (YouTube Help: Enhance your Shorts). Those guides show on screen but have no numbers.

So we measured. On 24 September 2026 we loaded Shorts in YouTube's mobile player on a 412-px-wide phone screen, read the position of each overlay, and scaled it to a 1080 × 1920 frame. Then we added room for longer titles and for the extra buttons the YouTube app shows.

How to use it:

1. Put on-screen text, faces and logos inside the clear area.
2. Keep the right edge clear from the middle of the frame down. The YouTube app shows more buttons there (dislike, remix and the sound disc) than the mobile web player.
3. Keep calls to action out of the bottom 420 px. A two-line title or a product tag pushes the overlay higher.
4. Backgrounds can run edge to edge. Only the important parts need to sit inside the box.

The Shorts margins are smaller than TikTok's. TikTok's own template needs 660 px at the bottom (see our TikTok video size guide). If you post the same video to both, design for the TikTok safe zone and it will be safe on Shorts too.

#Shorts thumbnail size

This is where the top search results are most often wrong. Many say a Shorts thumbnail is 1280 × 720. That is the size for regular videos. For Shorts, YouTube recommends a vertical image.

There are two ways to set the cover of a Short:

• Pick a frame (phone). In the YouTube app, tap Edit on the thumbnail on the final upload screen, pick a frame, and add text if you like. You can change it later from Your videos (YouTube Help: Create YouTube Shorts).
• Upload your own image (computer). In YouTube Studio, open Content → Shorts, click the pencil on your Short, and under Thumbnail click Upload file. Your account must be verified at youtube.com/verify first.

One trap: if you give a vertical video a 16:9 custom thumbnail, YouTube replaces it with "an auto-generated 4:5 thumbnail on the home, explore, and subscription pages" (YouTube Help). Make Shorts thumbnails 9:16 and keep the text in the centre, because feeds crop the edges.

#Export settings cheat sheet

Use these settings for every Short. They follow YouTube's own encoding page and stay far below every limit.

What that means for file size: a full 3-minute Short at 8 Mbps is about 185 MB. At 12 Mbps it is about 275 MB. A 30-second Short is under 50 MB. File size matters again if you post through a third-party YouTube scheduler, because some tools set their own upload caps.

Per app:

YouTube also asks you to keep the original frame rate. Do not turn 24 fps footage into 60 fps. It will look jerky, not smoother.

#Common errors and fixes

#Fix it with ffmpeg

If you have ffmpeg installed, one command turns any clip into a file YouTube will treat as a Short. This version fills the whole screen. It crops the sides of a landscape clip, so keep your subject in the centre:

 1ffmpeg -i input.mov -t 179 \
 2  -vf "scale=1080:1920:force_original_aspect_ratio=increase,crop=1080:1920,setsar=1" \
 3  -r 30 -c:v libx264 -profile:v high -preset slow -crf 20 -pix_fmt yuv420p \
 4  -c:a aac -ar 48000 -b:a 192k -movflags +faststart \
 5  short.mp4

This version keeps the whole picture and fills the rest of the 9:16 frame with black:

 1ffmpeg -i input.mov -t 179 \
 2  -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2,setsar=1" \
 3  -r 30 -c:v libx264 -profile:v high -preset slow -crf 20 -pix_fmt yuv420p \
 4  -c:a aac -ar 48000 -b:a 192k -movflags +faststart \
 5  short.mp4

What the settings do: -t 179 stops the file one second under the 3-minute limit. -crf 20 keeps quality high at a sensible size. -r 30 fixes the frame rate, which cures most sync problems (use -r 60 if you shot at 60). -movflags +faststart puts the index at the front of the file, which YouTube's encoding page asks for.

Use the second version only when cropping would cut off something important. YouTube prefers files without bars, so the first version is the better default.

#YouTube Shorts vs TikTok vs Instagram Reels specs

The same 1080 × 1920 file works on all three, so you can export once and post three times. The limits around it differ, and so do the best posting hours: compare the best hours for YouTube Shorts with the TikTok posting-time data.

Sources: YouTube Help pages linked above; TikTok figures from our TikTok video size guide; Instagram from Reel size and aspect ratios and Record a reel on the Instagram Help Center. For how the two biggest platforms differ beyond specs, read YouTube Shorts vs TikTok.

#Scheduling your Shorts

Getting the size right is one step. Posting on a steady schedule is the next. Our guide to scheduling YouTube Shorts covers YouTube Studio's own scheduler and the other options.

Schedule & Chill is a free scheduler that posts to YouTube, LinkedIn, Bluesky and Mastodon. The free plan includes 2 accounts, 500 posts a month and uploads up to 400 MB. A full 3-minute Short exported with the settings above is about 185 to 275 MB, so it fits. For YouTube you set the title, description, privacy, category and the "made for kids" answer. We upload your file as it is, so YouTube uses the same shape-and-length rule as a Studio upload: a vertical file of 3 minutes or less becomes a Short. We do not set custom thumbnails, so add a 9:16 one in YouTube Studio after it posts.

#Frequently Asked Questions

What are the dimensions of a YouTube Short? 1080 × 1920 pixels at a 9:16 aspect ratio. YouTube says Shorts have a maximum resolution of 1080p, so that is the largest size that fills the screen. Export it as an MP4 with H.264 video and AAC audio.

Are YouTube Shorts 9:16? Yes, 9:16 is the shape that fills the phone screen. YouTube also counts square and other vertical shapes, such as 4:5 and 3:4, as Shorts if they are 3 minutes or shorter. Those play with empty space above and below.

Is 1920 × 1080 good for YouTube Shorts? No. 1920 × 1080 is horizontal (16:9), and YouTube treats horizontal uploads as regular videos, whatever their length. Turn the frame upright to 1080 × 1920, or crop it with the ffmpeg command above.

Is 3:4 OK for YouTube Shorts? It works. A 3:4 video of 3 minutes or less is vertical, so YouTube treats it as a Short. It fills about 75% of the screen height and leaves empty space above and below. Reframe to 9:16 if you want the full screen.

What size is a YouTube Shorts thumbnail? 9:16, ideally 2160 × 3840 pixels, and at least 640 pixels tall, as a JPG or PNG. Custom Shorts thumbnails can only be uploaded in YouTube Studio on a computer, from a verified account. On a phone you can pick a frame from the video instead.

Can I upload a 4K YouTube Short? YouTube will accept the file, but its help page says Shorts have a maximum resolution of 1080p. A 4K file takes longer to upload and process for no visible gain on a phone. Export at 1080 × 1920.
