TikTok Video Size: Dimensions, Format, and Specs That Actually Matter

The recommended TikTok video size is 1080 x 1920 pixels at a 9:16 aspect ratio. This vertical format fills the full mobile screen and is the standard for all organic videos, stories, and ads. Upload in MP4 format at 1080p, and you're already ahead of most creators.

TikTok Video Size — Quick Reference Table

TikTok Video Dimensions and Aspect Ratio

TikTok supports three aspect ratios vertical, landscape, and square but only vertical 9:16 fills the full mobile screen.

Vertical 9:16 — The Standard

At 1080 x 1920 px, a vertical video fills the entire screen. There are no black bars, no wasted space, and no awkward cropping. This matches the native portrait resolution of most smartphones, so if you're filming directly on a phone, you're already in the right format.

In practice, this is the only ratio worth defaulting to. It's also identical to Instagram Reels dimensions, which makes cross-posting straightforward.

Creators increasingly active across digital platforms and online culture have made vertical-first formatting the default expectation, not the exception.

Landscape 16:9 — Supported but Suboptimal

TikTok accepts 1920 x 1080 px landscape videos, but they display smaller in the feed with letterboxing (black bars top and bottom).

That lost screen real estate tends to hurt watch time. Landscape works if you're repurposing content from YouTube or a presentation, but it's not a first choice for native TikTok content.

Square 1:1 — Also Supported, Also Suboptimal

Square videos at 1080 x 1080 px display with pillarboxing black bars on the left and right. Same issue: less immersive, less engaging. Occasional use case for repurposed Instagram feed content, but not ideal.

Resolution and Frame Rate

TikTok re-encodes every upload, so what you export matters more than what you shoot here's what to set before you hit upload.

Resolution

TikTok compresses every uploaded video, regardless of source quality. Because of this, 4K uploads get downscaled to 1080p anyway.

Exporting at 1080p gives you direct control over the quality before TikTok's compression pipeline touches the file rather than letting the platform decide how to reduce a 4K file.

What's often overlooked is that higher bitrate matters more than higher resolution here. A well-encoded 1080p file at 6–8 Mbps will hold up better after compression than a poorly encoded 4K file.

Frame Rate

30 fps is the baseline for most TikTok content. It's smooth, widely compatible, and doesn't inflate file sizes unnecessarily.

For fast-moving content sports, dance, transitions 60 fps reduces motion blur and keeps things visually sharp. TikTok supports a range of 23–60 fps across the board.

File Format and File Size

MP4 is the go-to format, but file size limits vary significantly depending on whether you're uploading from a phone or desktop.

Supported Formats

MP4 is the preferred format. It's compatible across all devices and upload methods, and TikTok handles it cleanly. MOV (common on iPhones) also works fine.

For codec, H.264 video paired with AAC audio gives the most reliable playback and the least compression degradation.

File Size — Platform Differences Matter

This is where it gets specific. The limits differ based on how you're uploading:

• Desktop or web upload: Up to 1 GB, with under 500 MB recommended for reliable processing
• iOS: Up to 280 MB
• Android: Up to 72 MB

If your file exceeds the mobile upload limit, TikTok will either compress it heavily or fail the upload entirely. For longer or higher-quality videos, upload from a desktop browser not the mobile app.

TikTok Video Length

Recording limits and upload limits are not the same and the right length for your video depends more on content type than platform rules.

In-App Recording vs. Uploading a Finished File

These two have different ceilings. In-app recording is capped at 10 minutes. If you're uploading a finished video file from your camera or editing software, TikTok supports up to 60 minutes a limit the platform has been expanding progressively, as reported by TechCrunch, though availability can vary by region.

What Length Actually Performs

TikTok's feed is built for short-form. That said, the right length depends on what you're making, and patterns vary significantly across different content types and creator niches.

According to engagement data from Statista, videos over 54 seconds saw the highest engagement rates though shorter clips under 10 seconds also performed strongly, suggesting the quality of the hook matters as much as the length itself.

These aren't rules they're patterns observed across content types. Longer videos can work, but only if the content earns the watch time.

TikTok Safe Zones — Don't Ignore These

Safe zones define which parts of the screen TikTok's own UI overlaps. If your text, logo, or key visual sits in these areas, it gets covered.

• Top 10% of screen: Reserved for notifications, live badges, and status indicators
• Bottom 15% of screen: Covered by captions, the like/comment/share button column, and the username/caption overlay

Keep all essential content text, faces, product shots centered between these zones. This is one of the most common reasons videos look cluttered or have important details cut off, and it's rarely explained clearly anywhere.

How TikTok Compresses Your Video

TikTok re-encodes every uploaded video. You don't get to skip this step. What you can control is what you give it to work with.

Uploading a high-quality source file — at 1080p, H.264, with a bitrate of 6–8 Mbps — gives TikTok's encoder more to preserve. Uploading a pre-compressed file essentially compounds the quality loss.

A few practical points:

• Export at the highest quality your editing software allows, within the 1080p ceiling
• Don't apply heavy compression before uploading — let TikTok handle the final pass
• Blurry output after upload is almost always the result of a low-bitrate source file, not a TikTok bug

Teams that produce regular branded content commonly report that bitrate, not resolution, is the variable that makes the biggest visual difference after compression.

TikTok Ad Video Size Specifications

Ad specs follow the same core format as organic video, with a few additions.

General Ad Requirements

Ad Format Breakdown

In-Feed Ads: Standard specs apply. Up to 60 seconds, but 15 seconds or under is where most engagement happens for skippable formats.

TopView Ads: Same resolution and format. Auto-plays with sound when the app opens. Can run up to 60 seconds.

Spark Ads: These boost existing organic posts, so the video specs are whatever the original post used — standard TikTok video specs apply.

Carousel Ads: Up to 10 images per carousel, each at 1080 x 1920 px. Mixed video and image carousels are not supported.

Videos that don't meet the 9:16, 1080 x 1920 px standard for ads may be rejected, cropped, or display with black bars any of which will hurt click-through rates.

Additional TikTok Content Specs

Beyond standard videos, TikTok Stories and profile images follow their own size requirements.

TikTok Stories

Same as standard video: 1080 x 1920 px at 9:16.

TikTok Profile Image

200 x 200 px at a 1:1 square ratio. Keep the subject centered the image displays as a circle in most contexts.

Conclusion

The core TikTok video size is 1080 x 1920 px, 9:16, in MP4 format with H.264/AAC encoding at 1080p.

Two things most people miss: safe zones (top 10% and bottom 15% are covered by UI) and compression behavior (bitrate matters more than resolution). Get both right and your videos will hold up well post-upload.

Frequently Asked Questions

What is the recommended TikTok video size?

1080 x 1920 pixels at a 9:16 aspect ratio. This fills the full mobile screen and is the standard for all TikTok video types, including organic posts, stories, and ads.

Why does my TikTok look blurry after uploading?

Usually a low bitrate on the source file. TikTok re-encodes every upload if the original file is already compressed, quality loss compounds. Export at 1080p with a bitrate of 6–8 Mbps before uploading.

What is the maximum TikTok video length?

You can upload videos up to 60 minutes via desktop or web. In-app recording is capped at 10 minutes. Most content performs best under 60 seconds.

Can I upload a 4K video to TikTok?

Yes, but TikTok compresses it to 1080p regardless. Exporting at 1080p directly gives you better control over the output quality than relying on TikTok to downscale 4K.

What video size should I use for TikTok ads?

The same as organic video: 1080 x 1920 px, 9:16. Keep files under 500 MB and duration under 60 seconds. For skippable in-feed ads, 15 seconds or less tends to perform best.
