An Instagram Reels cover is shown at 9:16 in the Reel and cropped square in your grid. One image has to survive both. Here is how to position it.
The Instagram Reels cover size is 1080×1920 — 9:16, the same as the Reel itself. The complication is that the same image is also cropped to a tile in your profile grid, and the two crops share far less area than people expect. A cover designed for one of them usually fails in the other.

Roughly the middle band
Anything at the very top or bottom of the cover — which is exactly where most people put their title text — is lost in the grid.
The cropper shows both crops at once from a single image, so you can position the subject and the text where they survive each.
The rule
Put the subject and the text in the central band. Vertically, aim for the middle half of the frame. If the cover has a title, that title belongs above or below centre — not at the very top, and never at the very bottom where the caption and interface also sit.
The interface bands matter for the full-frame view too: username, caption and the action rail cover the edges of a playing Reel — safe zones and Instagram Story size cover the same geometry.
Instagram lets you pick a frame from the video or upload an image. Upload one, almost always — a frame grabbed from the video is a frame of somebody mid-blink at whatever resolution the encode produced.
What makes a cover work in a grid of other covers:
A face or a single clear subject. Grids are scanned, not read.
Three or four words of text, large. At tile size, a sentence is texture.
Consistent treatment across your Reels. Recognition is what makes a profile look
Export the cover at 1080×1920 as a JPEG or PNG, then check the grid crop before publishing rather than after. Instagram recompresses, so an oversized file is downscaled by their encoder rather than yours — how to compress an image for Instagram.
If you are producing several sizes from one source, do it in one pass:
A Reels cover does two jobs that have nothing to do with each other, which is why it is easy to do one and forget the other.
In the Reels feed, the cover barely matters - the video autoplays and the first frame of motion is what holds someone. In the profile grid, the cover is everything: a visitor deciding whether to follow you is looking at nine tiles, and those tiles are the entire impression your account makes.
So the cover is not really a thumbnail. It is a component of your profile, and it should be designed as part of a set rather than one at a time. Accounts whose grids look deliberate are almost always using a consistent cover treatment - the same typeface, the same position, the same colour treatment - and it takes no more effort than doing it differently every time.
The test: open your own profile and squint. If the tiles read as a collection, the covers are working. If they read as a pile, no individual cover will fix it.
What size is an Instagram Reels cover?
1080×1920 at 9:16, the same as the Reel. It is also cropped to a tile in your profile grid, so the important content must sit near the centre.
Can I change a Reels cover after posting?
Instagram's editing options for a published Reel are limited and have changed over time. Treat the cover as something to get right before publishing.
Why does my Reels cover look cropped in my profile?
The grid shows a tile cropped from the centre of the 9:16 cover. Text at the top or bottom of the frame is cut.
Should I upload a cover or pick a frame?
Upload one. A frame from the video is rarely composed, and it is at whatever quality the encode produced.
Instagram carousel size is 1080x1350 per slide, and every slide must share the first one's ratio. Here is how to split one wide image so the seams disappear.
