TikTok Ad Sizes at a Glance
Pick the wrong ratio and TikTok crops your creative. Three aspect ratios are supported across all formats.
9:16 vertical is the TikTok default
Vertical fills the full screen on mobile. Minimum resolution is 540×960 px. Target 720×1280 px or higher for sharp results.
1:1 square and 16:9 horizontal also supported
Square (1:1) needs at least 640×640 px. Horizontal (16:9) needs at least 960×540 px. Vertical still wins on engagement for most placements.
Why aspect ratio impacts engagement and safety zones
TikTok overlays buttons, captions, and profile handles on every video. Wrong ratio means your content hides behind those elements. Get it right and your message lands clean.
In-Feed Ads (Most Common)
In-Feed Ads appear in the For You feed. They autoplay like organic content and are the standard format for most advertisers.
Dimensions: 540×960 px minimum (9:16) recommended up to 720×1280 or higher
Start at 540×960 px. Aim for 720×1280 px or higher. 1:1 and 16:9 also work at their respective minimums.
Duration: 5-60 seconds (9-15 seconds recommended)
TikTok allows up to 60 seconds. Short wins. 9-15 seconds drives the strongest engagement on this format.

Critical Safe Zones & Best Practices
Per TikTok's Business Help Center, the platform overlays UI elements across the bottom and right of every video. Keep key visuals clear of those zones or they get buried.
Keep text and logos out of bottom 20% and right 10% of frame
The bottom 20% holds your caption, CTA button, and profile info. The right 10% holds engagement icons. Text or logos placed there disappear behind the UI.
Avoid watermarks and TikTok UI imitation
TikTok bans watermarks in ad creatives, including TikTok's own watermark. Ads that imitate TikTok's native UI elements are also rejected.
Higher resolution (720p+) and audio are essential for TikTok performance
Low-res video looks bad at full-screen. TikTok is a sound-on platform. Silent or muted ads lose attention fast.
