Channel requirements
TikTok ad requirements
Curvi builds TikTok in feed ads to the rules below, then measures the output pixels against the size, background and fill rules before a file ships. This spec is compiled from public guidance and is pending verification against official documentation.
| Rule | Requirement |
|---|---|
| Exact size | 1080 by 1920 px |
| Background | No background rule published |
| Text on the image | Allowed |
| Formats | jpg, png |
| Safe zone | Keep the top 269 px, bottom 484 px, left 65 px and right 140 px clear of critical content |
What this means in practice
This format is more flexible than a marketplace main image, but sticking to the recommended size keeps the crop sharp and avoids compression artifacts.
Built to this spec from one photo
Curvi builds TikTok in feed ads from one photo of your product, measures the output pixels and attaches the report. A file that still fails a check after a retry is marked for review, and you are not charged for it.
