TikTok Safe Zone Checker (Free — Overlay Your Own Frame)

A TikTok video plays full-screen, but TikTok lays its own controls on top of your footage — and those controls don’t move for your content. The top of the frame carries the Following and For You tabs, the search icon, and the device’s status bar or notch. The right edge holds the vertical action rail: your profile avatar with the follow button, then like, comment, bookmark, share, and the spinning audio disc, stacked from roughly mid-frame downward. The bottom strip packs your @username, caption text, hashtags, and the scrolling music label — and that region can grow even taller when a caption expands or runs to multiple lines.

Anything you place under those areas is still in your video file, but viewers won’t reliably see it. The most common mistake is burning a key caption or a call-to-action into the lower portion of the frame, exactly where TikTok’s own caption block lands. Overlay your frame here and the collision becomes obvious before you publish instead of after.

The reliable real estate on a TikTok video is the centre of the frame, biased slightly upward. Keep faces, products, and any text that needs to be read inside that band — clear of the right rail and the bottom portion. If your hook is text, the upper-middle works best: high enough to avoid the caption block, low enough to clear the top tabs and status bar.

Remember that the overlays mark where the interface lives, not a hard crop. Your footage isn’t trimmed; it’s covered. A decorative background can bleed edge to edge quite happily — it’s the meaningful elements that need to stay in the open. When in doubt, treat the right quarter and the bottom fifth as borrowed space: fine for atmosphere, risky for anything a viewer actually needs to see or act on.

Each TikTok zone’s percentage is just its rectangle area over the full 9:16 frame — nothing more. The tool measures the interface, not your clip, so it can’t tell you whether the For You tabs are landing on dead space or whether the caption block is swallowing your punchline. We report the geometry plainly rather than inventing a "subject blocked" verdict that no in-browser tool could honestly produce.

The one number worth watching closely on TikTok is the caption block: it is drawn at its resting height, but a long or expanded caption grows it taller (the per-zone note flags the ~250–324 px range), so give the lower-middle of the frame extra clearance even if the overlay looks like it leaves room. Toggle the rail and caption zones in the legend as you reposition, and remember the layout is transcribed from documented TikTok measurements that shift between app versions and devices — plan with a margin, not to the pixel.
