TikTok video size and aspect ratio guide for brands (2026)

When your team produces TikToks for several brands or locations, one locked export spec saves you from re-cutting clips that crop badly or fail to upload. This guide gives you that spec: TikTok's own figures for size, aspect ratio, length, file size, covers, and ads, plus the settings we recommend when you publish at volume.

TikTok specs checked against TikTok's Ads Help Center and developer docs in October 2026.

Key takeaways

• Aspect ratio: 9:16 vertical is TikTok's recommended ratio. Export at 1080 x 1920 pixels (1080 wide, 1920 tall) to fill the screen. That size is our recommendation, not a TikTok rule. TikTok also accepts 16:9 and 1:1 video, but neither fills a phone.
• Length: every TikTok creator can post three-minute videos, and some accounts can post five- or 10-minute videos. Uploads through TikTok's posting API max out at 10 minutes.
• File size: it depends on the route. TikTok's posting API takes files up to 4 GB. In-Feed and TopView ads cap at 500 MB.
• Covers: the TikTok app has its own cover tools. When a tool publishes through TikTok's API, the cover is a frame of the video, the first frame unless another is set.
• For teams: lock one export spec per brand, keep text inside TikTok's safe zone, and schedule every account from one calendar. Sked Social schedules and auto-publishes TikTok videos.

Why TikTok video size matters in 2026

TikTok is a full-screen, vertical feed. A 9:16 video fills the phone. Anything wider plays with empty space around it or gets cropped, and TikTok's caption and buttons sit over the bottom and right of every video.

For a team publishing for several brands, a wrong export isn't one bad post. It's every client's version re-cut, re-approved, and re-scheduled. Get the spec right once and every clip clears. If you also publish to Instagram, LinkedIn, and X, our social media image sizes guide puts every network on one page.

TikTok video dimensions and aspect ratio for 2026

TikTok's ad specs list 9:16 vertical as the recommended ratio. The standard full-HD size for 9:16 is 1080 x 1920 pixels, and it's the size we recommend for every TikTok, organic or paid. It fills the screen and clears every minimum TikTok publishes.

Key specs:

• Recommended export: 1080 x 1920 px (9:16). Width comes first: 1920 x 1080 is a landscape frame.
• Other ratios TikTok accepts: 16:9 landscape and 1:1 square (TikTok ad specifications). Neither fills a vertical screen. True landscape videos with no text in the margins get a Full screen button (TikTok Creator Academy).
• 4:5 and 3:4: not listed by TikTok. Reframe them to 9:16 before you post.
• Dimensions TikTok's posting API accepts: 360 to 4,096 px on each side (TikTok for Developers).
• Minimum for 9:16 ads: 540 x 960 px.
• Frame rate: 23 to 60 fps (TikTok's posting API).

Why it matters: videos that don't match 9:16 may be cropped or show empty bars, which wastes the screen. Watch every export on a phone before it's scheduled.

Example: a fashion retailer with stores in three cities shoots every product drop at 1080 x 1920. The same clip then works on each store's TikTok account with nothing cut off.

Best TikTok video lengths for engagement in 2026

There's no magic length. Here's what TikTok documents:

• Every creator: three-minute videos.
• Some accounts: five- or 10-minute videos.
• Through TikTok's posting API: up to 10 minutes. TikTok may trim a video to fit an account's own limit.
• Ads: In-Feed ads run up to 10 minutes, TopView ads run 5 to 60 seconds (9 to 15 recommended), and Spark Ads have no duration restriction.

Let the idea set the length. Earn the first two seconds with a clear hook, quick cuts, and on-screen text, and cut anything that doesn't hold attention.

Example: an agency cuts a 15-second before-and-after for a salon client. It's short enough to rewatch and long enough to show the result.

TikTok video format and file size requirements

The limits depend on how the video reaches TikTok.

• Formats: MP4 (recommended), MOV, or WebM through TikTok's posting API. In-Feed ads also take MPEG, 3GP, and AVI.
• Codec: H.264 recommended. The API also accepts H.265, VP8, and VP9.
• Maximum file size: 4 GB through TikTok's posting API. 500 MB for In-Feed and TopView ads.
• Recommended resolution: 1080p (1080 x 1920).
• Length: up to 10 minutes through the API (see lengths above).
• Audio: embedded in the video file when you auto-publish.

Scheduling tools can set their own, lower limits. Sked Social's help center lists the file specs its TikTok auto-publishing accepts.

Example: a restaurant group exports a week of TikToks for six venues at one spec, MP4 at 1080 x 1920, so every file uploads first time.

Optimizing video clarity, resolution, and engagement

Sharp, well-framed video holds attention. Here's how to get it:

1. Shoot or export at 1080 x 1920 (vertical)
2. Use good lighting and clear audio
3. Keep key content centered to avoid cropping
4. Add captions and on-screen text for accessibility and sound-off viewing
5. Use trending sounds where they fit the brand
6. Export H.264 MP4 at 23 to 60 fps, and don't upscale low-resolution footage

4K or 1080p? TikTok's posting API accepts up to 4,096 px per side, so a 4K file uploads. TikTok doesn't publish its playback resolution, so a 1080 x 1920 master is the practical choice. Files stay smaller, and it clears every TikTok minimum.

Example: a real estate agency adds the suburb and price as on-screen text to each property tour, centered and clear of the caption area.

TikTok cover, thumbnail, and carousel specs

TikTok doesn't publish a pixel size for covers. What you can do with a cover depends on whether you post in the app or through a tool that uses TikTok's API.

Covers in the TikTok app

The TikTok app has its own cover tools when you post there. When a tool publishes for you, the API rules below apply.

Covers through TikTok's API

When a video is published through TikTok's Content Posting API, the cover is a frame from the video itself. The publishing tool can choose the frame. If none is set, TikTok uses the first frame (TikTok for Developers). So a 1080 x 1920 video has a 1080 x 1920 cover.

If you auto-publish, make that frame do the work: a clear subject and readable, centered title text.

Photo carousels

• Through TikTok's API: JPEG or WebP, up to 1080p and 20 MB per image, and up to 35 photos per post. The publishing tool chooses which photo is the cover (TikTok for Developers).
• Ratio: use one ratio across every slide. 9:16 at 1080 x 1920 fills the screen.

The best TikTok ad video sizes for 2026

TikTok publishes its own specs for each ad format, and they differ more than most guides admit. Here they are from TikTok's ad specifications (updated June 2026).

TikTok ad video size & format requirements

In-Feed ads (non-Spark):

• Aspect ratio and minimum size: 9:16 (recommended) at 540 x 960 px or more; 16:9 at 960 x 540 or more; 1:1 at 640 x 640 or more
• File formats: .mp4, .mov, .mpeg, .3gp, or .avi
• Length: up to 10 minutes
• File size: 500 MB or less
• Bitrate: 516 kbps or more

TopView ads: 9:16 at 540 x 960 or more; .mp4, .mov, .mpeg, or .3gp; 5 to 60 seconds (9 to 15 recommended); 500 MB or less; bitrate 2,500 kbps or more (TikTok TopView specs).

Spark Ads: these boost organic posts. Video is .mp4 or .mov, with no duration restriction.

Ad profile photo: 98 x 98 px (1:1), .jpg, .jpeg, or .png, under 50 KB, with the key element in the central 66 x 66 px.

A 1080 x 1920 export clears every minimum above.

Why size matters for TikTok ads

TikTok sets minimum sizes and file limits for each ad format, and creative outside them may not upload. Text outside the safe zone can be covered by the caption and buttons. The safe zone changes with the video's shape, the caption length, and any add-on formats, so TikTok publishes downloadable safe-zone files on its ad specs page.

Best practices for TikTok ad creatives in 2026

1. Hook viewers in the first two seconds with bold visuals and clear messaging.
2. Keep text and key visuals inside the safe zone. Use TikTok's safe-zone files as a guide layer in your editor.
3. Use high-contrast colors and large fonts for readability.
4. Add captions. Many people watch with sound off.
5. Test several lengths, for example 6, 15, and 30 seconds, to see what works for each audience.

Producing TikToks for a brand or for clients

Specs are the easy part. Keeping them consistent across five client accounts, or 40 locations, is where teams slip. These habits hold up:

• One spec sheet per brand. 1080 x 1920, 9:16, H.264 MP4, plus the brand's rules for where logos and text sit inside the safe zone. Share it with every editor and freelancer.
• File names that route themselves. Client, campaign, ratio, and date in the file name stop the wrong export reaching the wrong account.
• A cover frame designed on purpose. If your tool auto-publishes through TikTok's API, the cover is a frame of the video. Build a clean title frame into the edit for brands that want a consistent profile grid.
• Sign-off on the phone view. Approve the export as it will appear, with TikTok's caption area in mind, not the edit timeline.
• Head office masters, local text. For multi-location brands, head office supplies the 9:16 master and the safe-zone template. Local teams swap only the location details.
• Batch, then schedule. Export a week of clips at one spec, then schedule them in one sitting instead of posting from each brand's phone.

Expert tips & industry best practices for 2026

• Check every video on a phone before it's scheduled.
• Batch-create and schedule content to keep a steady posting rhythm.
• Review analytics weekly to see which formats and lengths hold viewers.
• Use captions and accessibility features to reach a wider audience.
• Cross-post with care. A 9:16 master also suits Instagram Reels. YouTube treats square or vertical uploads up to three minutes as Shorts (YouTube Help). Check LinkedIn video sizes and X video sizes before reusing a vertical clip there.

Top challenges & solutions

Challenge: Videos look blurry or get cropped
Fix: Export at 1080 x 1920 (9:16), width first, don't upscale, and keep key content centered. Check on a phone before scheduling.

Challenge: Text hidden by TikTok's caption and buttons
Fix: Keep text, faces, and logos inside the safe zone. TikTok's ad specs page has downloadable safe-zone files.

Challenge: Low engagement on longer videos
Fix: Hook viewers in the first two seconds, keep the edit moving, and use analytics to find the length that works for each brand.

Challenge: The wrong export reaching the wrong client account
Fix: One spec sheet per brand, clear file names, and one calendar for every account.

TikTok video size FAQ for 2026

What is the best TikTok video size for 2026?
1080 x 1920 pixels at 9:16. TikTok lists 9:16 as its recommended vertical ratio, and 1080 x 1920 is the standard full-HD size for it. It fills the screen and clears every minimum TikTok publishes.

What aspect ratio is TikTok?
9:16 vertical. TikTok also accepts 16:9 landscape and 1:1 square video, but neither fills a phone screen. TikTok doesn't list 4:5 or 3:4, so reframe those to 9:16 before posting.

What file formats does TikTok support?
MP4 and MOV work across every route. TikTok's posting API also takes WebM, and In-Feed ads also take MPEG, 3GP, and AVI. If in doubt, export H.264 MP4.

What's the maximum file size for TikTok videos?
It depends on the route. TikTok's posting API takes files up to 4 GB, and In-Feed and TopView ads cap at 500 MB. Scheduling tools can set lower limits, so check yours.

How long should my TikTok videos be?
As long as the idea needs, within TikTok's limits. Every creator can post three-minute videos, and some accounts can post five- or 10-minute videos. Uploads through TikTok's posting API max out at 10 minutes, and TopView ads run 5 to 60 seconds.

What size is a TikTok cover or thumbnail?
TikTok publishes no separate cover size. The TikTok app has its own cover tools. Through TikTok's API, the cover is a frame of the video, the first frame unless another is set, so it matches the video's 1080 x 1920 size.

How do I optimize my TikTok videos for clarity?
Shoot or export at 1080 x 1920, use good lighting, center key content, and check on a phone before posting.
