Short-form social video sizes
Create a practical vertical delivery copy.
A 9:16 vertical frame is the common starting point for Shorts, Reels, and TikTok. Preserve the master and make a smaller WebM preview separately.
Steps
- Keep essential content near the center.
- Resize a short representative clip first.
- Check text legibility on a phone.
How to verify the result
Example: make a smaller browser preview from a short creator clip.
Check: Browser codec support varies and the safe fallback may omit audio when necessary.
