Free Facebook Reels Safe Zone Checker

Quick answer: On a 1080×1920 canvas, keep key text and graphics at least 200px from the top, 340px from the bottom, 40px from the left and 130px from the right for Facebook Reels. These are measured estimates, last reviewed 2026-09-28, and can shift if the app updates its layout.

Facebook Reels run on the same 9:16, full-screen player as Instagram Reels — unsurprising, since Meta shares the underlying video stack between both apps — which means the interface chrome sits in almost the same places and a layout built for one usually survives a repost to the other with only small adjustments. The margins below come from measuring the live Facebook app directly, since Meta does not publish exact pixel values for either app.

What the Facebook Reels interface covers

Facebook draws a profile header and follow button across the top of the screen, the account name, caption text and audio label across the bottom, and a column of like, comment, share and more-options buttons down the right edge — the same basic arrangement as Instagram Reels, just with Facebook's own icon set. Keep logos, subtitles, calls to action and faces inside the dashed safe area shown in the visualizer above.

Shared layout, separate audience

Because Facebook and Instagram Reels use the same player, a video designed for one platform's safe zone will almost always clear the other's too, which is why the two use nearly identical margins here. The real difference is audience and discovery: Facebook's Reels feed skews toward an older, more established-follower audience than Instagram's, so hooks and captions that lean on trending audio references may land differently even when the framing is identical.

The 4:5 profile grid crop

Like Instagram, a Facebook Reel shown on a profile or page grid is cropped to 4:5 from the vertical center of the 9:16 frame, removing roughly 285 pixels from the top and bottom of a 1920-pixel-tall video. Turn on the 4:5 grid crop toggle above to check a cover frame or hook text before you commit to it.

Captions, hooks and hashtags

Facebook Reels captions collapse to two lines before a "more" link appears, so treat your first line as the hook the way you would on Instagram. Facebook's own guidance favors a lighter touch on hashtags than TikTok — two or three well-chosen tags outperform a long block of them in Facebook's own Reels ranking signals.

Burned-in subtitles

Facebook's automatic captions render in roughly the same band as Instagram's, about 1,400 to 1,720 pixels from the top of the frame. If you burn in your own subtitles, keep them above that band or accept that native captions, when a viewer turns them on, will sit on top of yours.

Cross-posting from Instagram

Because the two platforms share a player, the most common workflow is exporting once for Instagram Reels and reposting the identical file to Facebook. That works cleanly for the safe zone itself, but double-check the caption — a caption written for Instagram's audience and hashtag conventions doesn't always read naturally to a Facebook feed, so many creators rewrite the first line even when the video file is untouched. It's also worth checking whether the post is going to a personal profile, a Page, or a Group, since Facebook renders the same Reel slightly differently — a Page's name badge, for instance, can run a touch wider than a personal profile's — so a cover frame that clears the safe zone by only a few pixels is worth re-checking in each context rather than assumed safe everywhere at once.

A quick pre-export checklist

Before you publish to Facebook Reels, confirm the hook line is legible inside the dashed safe area exactly as it would be for Instagram, since the two share the same margins. Check the cover frame against the 4:5 grid crop the way you would for an Instagram post. If you're reposting a file that was already exported for Instagram, re-check the caption's first line reads well for a Facebook audience rather than assuming it will transfer as-is. And if this is also going to TikTok or Shorts, run the three-way comparison view to confirm the framing still clears their wider or narrower margins before calling it final.

Frequently asked questions

What are the Facebook Reels safe zone dimensions?

On a 1080×1920 canvas, keep key text and graphics at least 200px from the top, 340px from the bottom, 40px from the left and 130px from the right for Facebook Reels. These are measured estimates, last reviewed 2026-09-28, and can shift if the app updates its layout.

How long can a Facebook Reels caption be?

Up to 2,200 characters, but only the first 2 lines show before the "more" button truncates it.

What's the maximum length for a Facebook Reels video?

90 seconds, with a maximum file size around 4,000 MB.

Does FrameGuard upload my video or image?

No. Every file is read and drawn to a canvas inside your browser. Nothing is uploaded to a server, so your unreleased content stays private.

Are these safe zone numbers official?

No platform publishes exact pixel values for its interface. These are measured estimates, checked directly against the live apps, and each page shows the date they were last reviewed.

Is FrameGuard free?

Yes. The visualizer, caption studio, comparison view and PNG export are free with no account or sign-up.
