What is a safe zone in video?
By the KeyMo team · Updated
A safe zone is the part of a video frame where text and key visuals will not be cropped or covered by the app's interface. In vertical video it is the middle of the 9:16 picture, away from the profile strip, buttons and caption text that Reels, TikTok and Shorts draw over the edges.
Safe zone meaning in video editing
Meta's own help page defines the safe zone as the area where text overlays and logos will not be cropped out or covered by the user interface. That is the whole idea. A phone feed puts like buttons, a profile icon, a caption and a progress bar on top of your video, and whatever sits under them is hidden or hard to read.
What the platforms say
Official numbers are thin, and most of them are written for paid ads, not normal posts. This is what we could read on each platform's own pages.
| Platform | What its page says | Pixels on 1080x1920 |
|---|---|---|
| Meta (Reels ads) | About 14% of the top, 35% of the bottom and 6% of each side free of text, logos and key elements | Top 269, bottom 672, each side 65 |
| Meta (Reels ads with a disclaimer) | Keep the bottom 40% free | Bottom 768 |
| TikTok (in-feed ads) | The safe zone depends on the video size, the caption length and any extra formats; longer captions shrink it; downloadable guide files are offered | No figure given |
| YouTube Shorts | No safe-zone figure on the help pages we checked | No figure given |
Two things to take from this. First, the bottom is the big loser: more than a third of the height on Reels ads. Second, there is no single universal number, so a margin that works on one app can still be tight on another. Meta also warns that on screens taller than 9:16 an ad may be zoomed to fill the screen, which crops the edges further, or shown at 9:16 on a black background.
Where the idea came from
Television had safe areas long before phones did. The European Broadcasting Union's R 95 recommendation defines an action safe area and a graphics safe area for 16:9 TV, at 3.5% and 5% in from the top, bottom and sides. It covers 16:9 television production, not 9:16 social video, so do not reuse its numbers for a vertical clip.
Worked example: placing a caption block
Take a Reels clip at 1080x1920 and use Meta's ad percentages as a cautious guide. The text band runs from about y = 269 to y = 1248 and from x = 65 to x = 1015. A three-line caption set around the middle of that band, near y = 800 to 1000, clears every strip. The same caption at y = 1500 sits right where the caption and buttons live.
- Pick the platform you post to first.
- Keep captions, names and logos inside the middle band.
- Export, then watch the clip inside the real app on a phone.
- Move the text and check again if anything is covered.
Common mistakes
- Trusting an editor's built-in guide without checking it in the app. Guides go out of date when apps change their layout.
- Putting a lower-third name bar at the bottom. The caption and buttons land on it.
- Designing a face-and-caption layout on a 16:9 canvas and cropping later.
- Using the ad numbers as a hard limit for organic posts. They are written for ads.
Safe zone and KeyMo
KeyMo exports vertical 9:16 clips at 1080x1920 with captions in one of 12 styles. Because apps draw different things over the edges, open an exported clip in the app you are posting to before you publish. To measure your own frame, there is a safe zone checker, and the platform pages are in TikTok safe zone and Instagram Reels safe zone.
