TikTok Video Size and Dimensions: The Complete Guide
Updated July 2026 · KeepClip
Uploading a TikTok that ends up with black bars, cropped edges, or soft, blurry quality almost always comes down to one thing: the wrong dimensions. TikTok is built for a specific shape and size, and matching it is the difference between a crisp, full-screen video and an awkward one.
Here are the exact numbers that matter, and why they matter.

Step by step
- 1
Shoot vertical (9:16)
Hold your phone upright. TikTok is a full-screen vertical app — 9:16 fills the whole screen.
- 2
Aim for 1080×1920
Export at 1080 by 1920 pixels for full-HD sharpness that fills modern phone screens.
- 3
Keep it under the size limit
If your file is too big to upload, compress it first rather than letting TikTok crush the quality.

The numbers that matter
- Aspect ratio: 9:16 (vertical / portrait). This is the single most important one.
- Resolution: 1080 × 1920 pixels is ideal (full HD). 720 × 1280 is the acceptable minimum.
- Length: TikTok supports anything from a few seconds up to 10 minutes, though short clips (under 60 seconds) tend to perform best.
- File size: keep uploads reasonable — very large files get re-compressed harder, which softens quality.
- Frame rate: 30fps is standard; 60fps looks smoother for fast motion.
Why 9:16 matters so much
TikTok fills the entire phone screen, which is a tall, narrow rectangle — the 9:16 ratio. If you upload a square (1:1) or landscape (16:9) video, TikTok pads it with black bars or crops it to fit, and either way it looks amateurish and wastes screen space that could be showing your content.
Filming with your phone held upright automatically gives you 9:16. If you are editing on a computer, set your project or export canvas to 1080 × 1920.
Why your uploads look blurry
Two things soften TikTok uploads. First, uploading below 1080 × 1920 means the app upscales your video to fill the screen, which looks soft. Second, a very large file gets aggressively re-compressed by TikTok on upload.
The fix for the second problem is to compress the video to a sensible size yourself before uploading — you keep control of the quality instead of leaving it to TikTok. Our free video compressor does this in your browser.
Saving TikToks in full quality
When you save a TikTok from inside the app it comes with a watermark and is often lower quality. To keep a clean, full-quality copy of a video — your own, or one you have permission to use — use a downloader that fetches the original source file without the watermark, so what you save matches what was uploaded.
Frequently asked questions
What is the best TikTok video size?+
1080 × 1920 pixels at a 9:16 vertical aspect ratio. That is full HD and fills the whole screen.
What aspect ratio does TikTok use?+
9:16 (vertical / portrait). Square or landscape videos get black bars or cropping.
How long can a TikTok be?+
From a few seconds up to 10 minutes, though shorter clips under a minute usually get more engagement.
Why is my uploaded TikTok blurry?+
Usually because it was below 1080p (so TikTok upscales it) or the file was so large that TikTok re-compressed it hard. Export at 1080×1920 and compress to a sensible size first.
How do I save a TikTok without the watermark?+
Use a downloader that fetches the clean source file — our TikTok downloader saves videos in HD without the watermark.
