mimicA safe zone is the part of a vertical video the app doesn’t cover. On TikTok, Reels and Shorts the danger areas are the same: the bottom third (username, caption, music, ad buttons), the right edge (like, comment, share) and a strip along the top.
Meta’s rule for Reels is the clearest published number: keep the top 14%, bottom 35% and 6% on each side free of text and logos (Meta Ads Guide, 2026). Follow that and you clear TikTok and Shorts too, for a normal-length caption.

What a safe zone is, and why videos break
Every short-form app draws its interface on top of your video. Your username, the post caption, the music line, the follow button, the like/comment/share column and, on ads, a call-to-action button and a “Sponsored” label. None of that is in your editor’s preview. So a caption that looked perfect on your timeline ships with a heart icon through the middle of a word.
The fix is simple: decide where text can live before you add any, and keep it there. That area is the safe zone. Anything outside it is fine for picture (your face, the product, background) but not for words, logos or prices someone has to read.
TikTok’s ad help pages put it plainly: key elements such as text and logos must sit inside the safe zone, and the in-feed zone is more restrictive than full-screen placements (TikTok Ads Help Center, 2026).
Safe zones by platform
The three apps publish their guidance differently. Meta gives percentages. TikTok gives template files that change with caption length and placement (TikTok Ads Help Center, 2026). YouTube’s help pages give format rules but no margins, so the Shorts row below is our working margin, not an official number.
| Platform | Keep clear | On 1080×1920 | Source |
|---|---|---|---|
| Instagram Reels | Top 14%, bottom 35%, 6% each side | ≈269 px top, 672 px bottom, 65 px sides | Meta Ads Guide |
| TikTok | Bottom third, right-hand button column, top bar. Exact zone depends on caption length and ad format | Download TikTok's safe-zone file for your format | TikTok Ads Help |
| YouTube Shorts | Bottom third (title, channel, subscribe, ad button), right-hand buttons | Use the Reels margins as a floor | Our recommendation |
Why the bottom is so large: that’s where everything stacks. On an ad, the call-to-action button sits above the caption, which sits above the music line. On a long caption, TikTok shows up to four lines before “See more” (TikTok Ads Help Center, 2026), so a wordy caption eats more of your frame.
Horizontal footage on Shorts: Google says 16:9 videos still run in Shorts ads but with blurred bars above and below (Google Ads Help, 2026). Shoot vertical.
One safe zone for all three apps
Most UGC gets posted to TikTok, Reels and Shorts from the same export, so it’s easier to design for the strictest overlap than to make three versions. On a 1080×1920 frame:
- Top: nothing readable above about 270 px (14%). That clears the Reels margin and TikTok’s Following/For You tabs.
- Bottom: nothing readable below about 1,250 px (65%). That’s Meta’s 35%, which also covers TikTok’s caption and ad button for a short caption.
- Right: keep text at least 150 px off the right edge, where the button column runs. Meta’s 6% (65 px) is the minimum on the left.
- Faces: the safe zone for text is also where your face usually is. Text goes above or below the face, never across it.
That leaves a band roughly 870 px wide and 980 px tall in the middle of the frame. It’s smaller than you think, which is why captions should be short: two to four words a line, one or two lines at a time.
Want to see it on your own frame? Drop a screenshot into the safe zone checker and the overlays for each app draw on top.
Where to put each kind of text
| Element | Where | Why |
|---|---|---|
| Hook title | Upper middle, 15–30% down | Seen first, clear of the top bar, above the face on a chest-up shot |
| Word-by-word captions | 55–65% down, centered | Below the chin, above the app's caption block |
| Callouts and keywords | Beside the face, inside the side margins | Adds emphasis without covering the speaker |
| Product name, price, offer | Middle band, never bottom | The bottom third is where ads put their own button |
| Logo | Top-left inside the margin, or leave it out | Bottom corners are always covered |
| Call to action | Spoken, plus text in the middle band | The app's own CTA button already owns the bottom |
Captions at the very bottom of the frame, a promo code in the bottom-right corner, logo bottom-left. On TikTok all three sit under the caption, the share button and the username.
Hook text at 20% height for the first two seconds, then captions at 60% height, two words at a time. The promo code appears center-frame for two seconds when it’s spoken.
How to check your video before posting
- Export at 9:16. 1080×1920 is the standard. Meta recommends 1440×2560 for Reels ads (Meta Ads Guide, 2026).
- Grab a frame from the busiest moment: the most text on screen at once.
- Overlay the zones. Use the platform’s template (TikTok offers downloadable files on its in-feed ads page (TikTok Ads Help Center, 2026)) or our safe zone checker.
- Preview on a phone. Post as private, or use TikTok’s ad preview, and look at it with your real caption. A long caption pushes the bottom zone up.
- Check the first three seconds hardest. That’s when people decide to stay, and on TikTok TopView ads, when the logo and skip button are on screen (TikTok Ads Help Center, 2026).
Mimic does this for you: every caption, title and callout it places stays inside the apps’ safe zones and off the speaker’s face, even when the reference video you’re copying put text somewhere it shouldn’t.
Common safe-zone mistakes
- Designing in a 16:9 editor and cropping later. Text placed for a wide frame ends up off the sides.
- Trusting the editor preview. No editor shows the app’s buttons unless you add the overlay.
- Captions too big. Huge three-line captions spill out of the band. Fewer words per line, not bigger letters.
- Forgetting the ad version. A post that’s safe organically can break when a brand runs it as a Spark Ad or partnership ad, because the CTA button appears. Ask whether your UGC will be run as an ad; see usage rights and whitelisting.
- White or transparent backgrounds. TikTok bans plain white in the first three seconds of TopView ads (TikTok Ads Help Center, 2026), and the app’s white text disappears on it anyway.
Questions
What is the TikTok safe zone?
The part of a 9:16 video that the app's buttons, username, caption and music line don't cover. On a 1080×1920 frame, keep text and logos out of the bottom third, off the right edge where the like, comment and share buttons sit, and below the top bar. TikTok publishes downloadable safe-zone files for ads in its help center.
What is the Instagram Reels safe zone?
Meta's ads guide says to leave at least 14% of the top, 35% of the bottom and 6% of each side free of text, logos and key creative. On a 1080×1920 Reel that is about 269 px at the top, 672 px at the bottom and 65 px on each side.
Is there one safe zone that works on TikTok, Reels and Shorts?
Close enough. If you keep text inside the band from roughly 15% to 65% of the height, and away from the right 15% of the width, it clears all three apps' overlays for a normal-length caption. Always preview the actual upload, because overlays change with caption length, ads vs organic, and app updates.
Where should captions go on a TikTok?
Just above the lower third: around 55 to 65% of the way down the frame. That's low enough to stay off the speaker's face and high enough to clear the post caption and buttons.
Do safe zones matter for organic posts or only ads?
Both. The like, comment and share buttons, your username and caption cover organic posts too. Ads add a call-to-action button and a 'Sponsored' label, which push the bottom zone further up.
What resolution should a TikTok, Reel or Short be?
Shoot and export 9:16. 1080×1920 is the standard; Meta recommends 1440×2560 for Reels ads, and TikTok's minimum for non-Spark ads is 540×960.
