TikTok Ads Creative Specs 2026: In-Feed Video and Safe Zones
TikTok in-feed ad dimensions, formats, file limits, duration and safe-zone guidance based on current TikTok Ads Manager documentation.
TikTok supports more than one in-feed ratio, but vertical video is the recommended starting point. Build for the native feed first, then use the safe-zone file and live preview to protect the hook and CTA.
TikTok Ads Creative Specs 2026 cheat sheet
| Format | Recommended | Minimum / limit | Notes |
|---|---|---|---|
| Non-Spark vertical | 9:16 | ≥ 540×960 px | TikTok's recommended in-feed orientation; keep important elements clear of UI overlays. |
| Non-Spark horizontal | 16:9 | ≥ 960×540 px | Use only when the concept genuinely benefits from landscape framing. |
| Non-Spark square | 1:1 | ≥ 640×640 px | A supported fallback, but it does not fill the screen like vertical creative. |
| File and delivery | .mp4 or .mov | ≤ 500 MB; ≥ 516 kbps bitrate | Non-Spark video can run up to 10 minutes; check the objective and placement before publishing. |
| Spark Ads | Native organic video | .mp4 or .mov | Captions are pulled from the organic video caption and the account profile is used for identity. |
How to prepare the creative
- Put the visual hook in the opening seconds and keep the product or proof readable on a small screen.
- Download the region-specific safe-zone file from TikTok before finalizing text placement.
- Use TikTok's preview and add UTM parameters so creative performance can be compared with other channels.
