Instagram Reels Safe Zone Checker (Free — Overlay Your Own Frame)

A Reel plays full-screen, but Instagram lays its own controls on top of your footage — and those controls don’t move out of the way for your content. The top of the frame carries the Reels label and the status bar. The right edge holds the vertical action rail: like, comment, share, save, and the spinning audio disc, stacked through the lower-middle of the screen. The bottom strip is the busiest zone of all, packing your username, the follow button, the caption, and the audio credit into the lower fifth — and below that, the phone’s own navigation bar and home indicator.

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

The reliable real estate on a Reel is the centre of the frame, biased slightly upward. Keep faces, products, and any text you need read inside that band, clear of the right rail and the bottom third. If your hook is text, it works best in the upper-middle — high enough to clear the caption block, low enough to clear the top bar.

Remember the overlays mark where the interface lives, not a hard crop. Your footage isn’t trimmed; it’s covered. A decorative background can run 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 quarter as borrowed space: fine for atmosphere, risky for anything a viewer has to actually see.

The percentage under each Reels overlay is a measure of one thing: how much of the 9:16 frame that rectangle covers. It is plain geometry from the zone’s width and height — the tool never inspects your footage, so it will not tell you whether the spinning audio disc at the bottom is sitting over your subject’s face or over empty sky. That judgement is yours, and we think showing you an honest interface map beats inventing a “subject blocked” score a browser can’t actually compute.

Reels has a couple of traps the raw numbers won’t flag on their own: the audio attribution disc spins in the lower-left exactly where creators love to drop a caption, and the Follow button can render inline at the top of the action rail, widening that right-hand column beyond the bare icons. Toggle each zone in the legend while you reposition, and lean on the per-zone notes — the rail and caption measurements are transcribed from documented Reels layouts, which Instagram still nudges between app versions and devices, so keep a little margin.
