TikTok Video Size at a Glance (2025)
Follow these official TikTok settings for the best results:
| Setting | Recommended |
|---|---|
| Resolution | 1080 × 1920 pixels |
| Aspect Ratio | 9:16 (vertical) |
| File Format | MP4 or MOV |
| Max Length | Up to 10 minutes |
| Frame Rate | 30 FPS or higher |
✅Pro Tip & Best Practices:
- Always shoot vertical (9:16) for maximum screen coverage

Why Optimizing Video Size Matters
TikTok prioritizes immersive full-screen videos. Using the wrong size can result in:

- Reduced engagement due to black bars or cut-off text
- An unprofessional appearance
Common Mistakes to Avoid:
- Uploading horizontal YouTube clips without resizing
- Using 720p videos (blurry on most screens)
- Ignoring compression—large files often fail on Android
