Instagram Reels safe zone for subtitles
Measured from a real phone, not scaled from a web player — with the exact limits of that measurement.
What can overlap a subtitle
Reels draws two things over the video on the right and bottom-left: a vertical action rail (like, comment, share, bookmark) down the right edge, and a profile/audio row (avatar, username, follow button, and the audio line) lower on the left. A wide subtitle near the bottom edge tends to reach the profile/audio row first; a subtitle pushed toward either side can catch the action rail.
What the tool loads for Reels
In Reference · Organic mode, the active Reels reference is a first-party capture: a physical Galaxy S20 Ultra, Instagram app 477.0.0.55.81, Korean UI, captured 2026-09-23. Of 15 screenshots reviewed, 9 qualified as plain single-video playback (no collection or hashtag header, no paused-state controls, no carousel badge) and became the base measurement. Confidence is recorded as medium-high.
Two regions are loaded — and both are clipped to only the part that actually sits over the video, not the full icon column:
- Action rail — the like-through-bookmark icon column, from where the like icon starts down to the bottom of the video frame. The audio-disc thumbnail below that point falls outside the video and isn't included.
- Profile / audio row — the avatar, username, and follow button, again cut off exactly where the video frame ends.
Two things that look like they'd overlap, don't, in this capture: the caption text itself and the comment-input bar both render below the actual video frame, in the letterboxed margin — so they're recorded as measurements but not loaded as collision regions.
Recorded regions
| Region | x | y | Width | Height |
|---|---|---|---|---|
| Right action rail (part over the video) | 936 | 908 | 144 | 1012 |
| Profile, follow and audio row (part over the video) | 0 | 1795 | 1080 | 125 |

Values exactly as recorded, with no safety margin added and no averaging across sources. Only these regions are checked. Real UI changes with device, app version and caption length.
Using it
Switch Data to Reference · Organic, place your Subtitle, and check the Reels column. A caption sitting fully above the profile/audio row and clear of the right-edge action rail should read Safe against this reference.
Limitations
- Single device, single session — Android only, one app version, one locale. iOS, other phones, and other app versions weren't captured.
- Caption was collapsed to one line in every sample; the expanded "more" state wasn't captured, so we don't yet know whether it pushes further into the video.
- Carousel posts (numbered badge + dot indicator) were seen in only 2 of 15 screenshots — too few to include, so they're tracked separately and not loaded here.
