The usable area is not a neat rectangle
The row of buttons on the side only covers the lower half. Above it, you can use the full width — and that upper strip is usually the best spot for your opening line.

Your creative
Your video or image is opened and measured inside your own browser. It is never sent to us, so we cannot analyse it, store it, or use it for anything else.
Drop a video or image
MP4, WebM, MOV, JPG, PNG or WebP. Vertical 9:16 works best.
Ad type
Ads with a product card leave less room at the bottom.
Caption lines
Longer captions cover more of the bottom.
The safe area follows TikTok's published in-feed spec. The app's layout shifts between versions, so preview once in Ads Manager before a big launch.
TikTok publishes a full interface reference for the product-card placement only, so that one shows the real interface. For plain in-feed you get the measured boundary on its own — we would rather show nothing than draw an interface from guesswork.
01 · What gets covered
Three things this makes obvious
None of them show up in your editing software, because your editor shows the full frame.
A longer caption covers more
On ads with a product card, every extra line of caption pushes the covered area further up the frame. Captions are usually written after the video is finished, which is how text ends up hidden.
Covered does not mean rejected
A hook sitting under the caption still plays and still passes review. It just does not get read. You see it later as people dropping off early, not as an error.
02 · Use cases
When people use it
Each of these goes wrong quietly — the ad runs, and you only notice in the numbers.
Checking a creator video before it runs
Creators shoot for a full screen. Subtitles burned along the bottom are the thing the caption area covers most often.
Placing price, offer and logo
Offers tend to go bottom-centre out of habit. On an ad with a product card, that is the first thing to disappear.
Reviewing a batch from your editor
Run each export through once, then send the overlay PNG to your editor so they can work to the real boundary next time.
03 · How to use
Three steps
No account, nothing to install, and your file never leaves your device.
Add your file
A video or a still image. It opens straight in the frame.
Pick your ad type
In-feed or with a product card, then set how long your caption is.
Move anything covered
Adjust it in your editor, or download the overlay PNG and use it as a guide layer.
04 · FAQ
Common questions
About the measurements, the ad types, and what this tool leaves to Ads Manager.
Why is the safe area not a rectangle?
Because the buttons down the side — profile, like, comment, share, sound — only take up the lower part. Above them you can use the full width between the side margins, which is worth knowing when you place your opening line.
Which ad type should I pick?
If your ad shows a tappable product card above the caption, pick With product card. If it is a plain in-feed video ad without that card, pick In-feed. The two leave different amounts of room.
Does a longer caption really matter?
Yes. On ads with a product card, each extra caption line covers a bit more of the bottom. Going from one line to four hides roughly another tenth of the frame, so it is worth checking again once the caption is final.
Does the overlay end up in my file?
No. Your file is not changed and not uploaded — the overlay only sits on top for preview. If you want it in your editing timeline, use Download overlay PNG and you get a transparent layer at your file's size.
Where do the measurements come from?
They follow TikTok's published in-feed safe zone, including the separate figures for ads with a product card at one to four caption lines. App layouts change between versions, so preview in Ads Manager as well before a big launch.
Why does it not tell me if my length or file size is allowed?
Those limits change by ad type, market and how you buy, so we show you the number rather than pass a judgement we cannot stand behind. Shape and size are checked, because those come from the same spec as the safe zone.

Once the framing is right, the question becomes whether the creative still works
Checking the safe zone is a one-off — you do it before the ad goes out and never again. What keeps costing money is a creative that slowly stops performing after it is live, usually noticed only once the budget is gone. Tec-Pulse watches every GMV Max creative for you and flags the ones that have started to slide, with the likely reason.
