Safe zones for Instagram Reels texting stories
A Reel is covered at the bottom and the right by the app's own interface. Know the margins, check the cover crop and keep the key bubble in the clear middle.

Check the last bubble. Is it cut off?
Which one? Mine or yours?
The important one.
It is under the caption.
What sits on top of your picture
In a Reel, the username, caption and buttons overlap the bottom and the right side. A 1080 by 1920 frame is the usual size, so on the 1920 side keep important words out of roughly the bottom 20 to 25 percent, the top 10 percent and the right edge. The exact layout varies by phone and changes with app updates, as of November 2026.
Do the arithmetic on a 1920 pixel frame
Ten percent of 1920 is 192 pixels at the top; 25 percent is 480 pixels at the bottom. That leaves a middle band of about 1250 pixels. Fit the whole chat inside it. In the sample, the final bubble is the one that matters, and a chat that grows downward pushes it exactly into the caption area, so cap the number of visible bubbles or let older ones scroll up.
The cover frame and the grid
A Reel's cover can be cropped differently in the profile grid than in the feed. Choose a frame with the chat centred and the face of the story, such as the title bar and the first message, near the middle. A cover that hides the interesting text at the edges looks empty in the grid.
Test with a real overlay
Upload the video as a private draft or share it with yourself, then look at it with the caption written. Scroll to the end and pause. If any bubble is touched by the caption or the buttons, trim a bubble or move the story up before you publish.
Tips
- Keep key words out of the bottom quarter and off the right edge.
- Treat the middle 1250 pixels of a 1920 pixel frame as your canvas.
- Limit visible bubbles so the last one never reaches the caption.
- Pick a cover frame with the chat centred, not at the edges.
- Check the draft with the real caption text already written.
Questions
Are these margins exact?
No. They are typical safe margins. Phones differ and the app changes, so test your own export before posting.
Can ChatsRat show the overlay on its preview?
The live preview shows your chat, not another app's buttons. Apply the margins yourself and check a draft on a phone.
What aspect ratio should I export?
9:16 for a Reel. Video export, including all four shapes, 9:16, 16:9, 1:1 and 4:5, needs the Creator plan.
Does the same layout work on other platforms?
Roughly, since most vertical apps cover the bottom and right. Each platform has its own details, so check separately.
Use it for simulated, labelled content. ChatsRat makes mock-ups and fictional conversations for creators, designers and teachers. Do not use it to pass off a made-up conversation as a real one, to impersonate a real person, or as proof of anything. See the Acceptable Use policy.
About the watermark. Exports on the Free plan carry a visible ChatsRat watermark, and every export carries an invisible mark that the verify page can read. Plans list what changes on paid plans.
