TikTok Ad Preview —
9:16 Safe Zone & Character Limit Simulator

A TikTok ad description truncates around 100 characters, after which the platform appends an unclickable "... See more" and clamps the visible text to roughly four lines. Anything past that is hidden unless a viewer taps. Because TikTok is sound-on, fast-scrolling, and full-screen, your first line has to earn the watch — the simulator above shows the exact cutoff so your hook is never buried.

This is the single biggest mistake in TikTok creative: baking text or logos into the parts of the video that TikTok's interface covers. On a vertical 9:16 video, the UI blocks three regions — the top ~10% (the For You / Following tabs and status bar), the bottom ~20% (username, caption, call to action, and the music ticker), and the right ~15% (the profile photo plus the like, comment, bookmark, and share icons). Toggle the Safe Zone overlay to see these blind spots as translucent red bands, so you know precisely where hardcoded text would be hidden.

Keep captions, prices, disclaimers, and logos inside the clear central area — never in the top bar, bottom fifth, or right rail. If you must place text low, raise it well above the caption block. Design for the interface from the first frame rather than discovering the collision after the ad is live.

Upload a vertical thumbnail to the 9:16 canvas, type your description, and toggle the overlay — all in your browser, with nothing uploaded or stored. You will see your TikTok ad the way users do, with the safe zones mapped, before you ever push it to TikTok Ads Manager.
