Ad Specs
The dimensions, length, and file limits for TikTok In-Feed ads — plus the safe zones most people forget. TikTok changes specs from time to time, so use this as a working reference and confirm anything critical in Ads Manager.
| Field | Spec |
|---|---|
| Aspect ratio | 9:16 (vertical) |
| Resolution | 1080 × 1920 recommended (540 × 960 min) |
| Length | 5–60s; 9–15s recommended |
| File type | MP4, MOV, MPEG, AVI |
| File size | Up to 500MB |
| Bitrate | ≥ 516 kbps |
TikTok's UI eats the right ~10% (the like/comment/share rail) and the bottom ~20% (username and caption). Keep captions, logos, and your CTA in the central column so the interface never covers the point of the ad.
A 1080×1920 file that meets every requirement still fails if the opening doesn't stop the thumb. On TikTok, more than most platforms, the hook in the first 1–3 seconds decides everything (see best TikTok ad length). Native-feeling, sound-on, fast-opening creative beats polished ads that look like ads.

Score Your AdTikTok In-Feed ads are vertical 9:16, ideally 1080×1920, MP4 or MOV, under 500MB. Length can run 5–60 seconds but 9–15 seconds performs best. Keep text and logos inside the safe zone so the right-side icons and bottom caption don't cover them. TikTok updates specs periodically — confirm in Ads Manager.
9–15 seconds is the sweet spot for most In-Feed ads. TikTok allows up to 60 seconds, but attention drops fast — the hook in the first 1–3 seconds decides whether the rest is seen at all. Longer only works if every second earns the next.
Keep important text and branding out of the right ~10% (like, comment, share icons) and the bottom ~20% (username and caption). Center your key message so the interface never covers it. Ads that ignore the safe zone lose their call-to-action behind the UI.
