Safe zones (approximate on 1080 × 1920)
- Keep about the top 240 px, bottom 660 px and 120 px on each side clear.
- Leave extra room on the right, where the like, comment, share and profile buttons sit.
- These numbers are scaled up from TikTok's 720 × 1280 ad template as cited by third parties. They aren't published as an official TikTok standard.
