If you have ever uploaded a video on TikTok and noticed black bars, blurry quality, or cropped text, the problem is usually not your editing skills — it is the video size. TikTok is a vertical-first platform, and videos that don’t follow the correct dimensions often perform poorly.
Using the right TikTok video size helps your content look professional, fill the entire screen, and get better engagement. When your video fits perfectly, viewers are more likely to watch till the end, like, comment, and share.
In this complete guide, you will learn everything about TikTok video size, aspect ratio, resolution, file format, resizing methods, and the best tools to create perfectly optimized videos.
This guide covers:
- Official TikTok video size
- Best resolution for high-quality videos
- Correct aspect ratio for TikTok
- How to resize videos on PC and mobile
- Best editing tools for resizing
- Tips to improve video performance
Let’s start with the official size requirements.
TikTok Video Size at a Glance
To get the best results on TikTok, you should follow the recommended settings below.
| Setting | Recommended Value |
|---|---|
| Resolution | 1080 × 1920 pixels |
| Aspect Ratio | 9:16 (Vertical) |
| File Format | MP4 or MOV |
| Frame Rate | 30 FPS or higher |
| Max Length | Up to 10 minutes |
| Orientation | Vertical |
These settings ensure your video fills the screen without cropping or losing quality.
Why 1080 × 1920 is Best
This resolution matches most smartphone screens and gives sharp quality without increasing file size too much.
Why 9:16 Aspect Ratio Matters
TikTok is designed for vertical viewing. If you upload horizontal videos, TikTok will add black bars or crop the video.

Correct video size helps with:
