The short version: Your Instagram Reels cover should be 1080 x 1920 pixels, a 9:16 ratio, saved as a JPG or PNG under 30MB. But the size on the spec sheet is not the size people see, because your profile grid crops that cover down hard, and if you center your logo or face the way most tutorials tell you to, it gets sliced off. I learned this the expensive way with a client's launch reel, and I will walk you through exactly how to build a cover that survives every crop Instagram throws at it.
The exact pixel size to use
Instagram Reels play at 1080 x 1920 pixels, which is a 9:16 vertical ratio. Your cover image, whether it is a frame from the video or a custom upload, should match that. Not close. That exact ratio.
If you upload a cover that is a different shape, Instagram stretches or crops it to fit, and you lose control over what gets cut. I have seen brand logos end up half off-screen because someone uploaded a square 1080 x 1080 image thinking "it's Instagram, everything's square." Reels are not square. They never were.
File size wise, keep it under 30MB and stick to JPG or PNG. Anything heavier and Instagram will compress it for you, and compression on text-heavy covers turns clean type into mush.
The bit most guides skip: your grid crops the cover, hard
Here is the uncomfortable truth. That perfect 1080 x 1920 cover you just built does not show up full size anywhere except when someone opens the reel itself. On your profile grid, where most people decide whether to tap on your content, Instagram crops it down to roughly a 3:4 rectangle. That means it slices off a meaningful chunk from the top and bottom of your image before anyone sees it in the grid.
I found this out with a jewellery client who had her logo perfectly centered vertically in every reel cover, exactly the way three different "how to design Reels covers" articles told her to. On the individual reel view it looked flawless. On her profile grid, the top third of her logo was gone. Cropped clean off. We only caught it because a follower screenshotted it and asked if it was intentional. It was not.
The fix is simple once you know it exists: treat the middle 55 to 60 percent of your 1920-pixel-tall cover as the only zone guaranteed to survive both the full reel view and the grid crop. Anything you need people to see, your face, your logo, your headline text, goes in that middle band. The top and bottom edges are for background, not content.
Step by step: building a cover that holds up
- Start with a 1080 x 1920 pixel canvas in Canva, Photoshop, or your editor of choice.
- Drop your background image or video frame to fill the full canvas, no letterboxing.
- Map out three horizontal thirds. The top third (roughly the first 500 to 550 pixels) and the bottom third (the last 500 to 550 pixels) are the danger zones. Grid crop and Instagram's own overlay icons live there.
- Place your face, product, or logo in the middle band, between roughly pixel 550 and pixel 1370.
- If you're adding caption text or a headline, keep it inside that same middle band and use a font size no smaller than about 60px so it is still legible when the grid shrinks it further.
- Export as a PNG for text-heavy covers (cleaner edges) or JPG for photo-heavy ones (smaller file size).
- Upload it through "select cover" when posting, rather than letting Instagram auto-grab a random frame from your video, which almost always lands mid-blink or mid-word.
Custom cover versus a frame grab
You have two options when you post a reel: let Instagram pull a frame automatically, or upload your own custom cover from your camera roll. Almost every business account should be doing the second one, every single time, and most still are not.
Auto-grabbed frames are a gamble. Instagram tends to grab something from the first second or two of the clip, which for most of us is a half-formed expression, a shaky first frame, or blank space before the actual content starts. A custom cover means you control the crop, the branding, and the message before anyone even presses play.
If you're running multiple reels a week and want them to look like they belong to the same brand rather than five different accounts, this is where keeping your Reels branding consistent with a logo earns its place. Same logo position, same colour band, same font for text overlays, every single time. It sounds fussy. It is the difference between a profile grid that looks intentional and one that looks like a scrapbook.
Safe zones for text, stickers, and Instagram's own UI
Even once your cover is uploaded, Instagram overlays its own elements on top when someone is watching the reel: the caption text, your username, the like and comment icons down the right side, the audio credit, the follow button. None of that touches the grid thumbnail, but it absolutely covers parts of the full-screen play view.
The right-hand edge, roughly the last 200 pixels of width, is where the like, comment, share, and save icons sit. If you have not looked closely at what each of those does versus just glances past them, it is worth understanding what the Instagram Reels icons mean before you plan text placement around them, because two of them shift position depending on whether the reel has music attached.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Bottom line for text overlays on your cover or in-video captions: keep anything essential inside the central 70 percent of the frame, both horizontally and vertically. Corners and edges are reserved for Instagram's chrome, not your message.
Where this fits into the wider content plan
A cover that survives the crop only matters if people get shown the reel in the first place. Getting found matters just as much as looking sharp once someone lands on your profile, which is why pairing a strong cover with proper tagging, using something like a free hashtag generator to get relevant tags in seconds rather than guessing, tends to move the needle more than either move on its own.
And if you're cross-posting the same reel to Facebook, remember the two platforms do not treat length the same way. Before you assume a reel that works on Instagram will behave identically on Facebook, it is worth checking whether there's a time limit for Facebook Reels and what that means for how you cut and cover your video for each platform separately.
What I'd tell you if you only remember one thing
Build every cover at 1080 x 1920. Keep your logo, face, and text inside the middle 55 to 60 percent of that frame. Upload a custom cover rather than trusting the auto-grab. And check your actual profile grid after posting, not just the reel preview screen, because that grid crop is where the real damage happens and almost nobody checks it until a follower points it out first.

Frequently asked questions
What is the exact pixel size for an Instagram Reels cover?
1080 pixels wide by 1920 pixels tall, a 9:16 vertical ratio, saved as a JPG or PNG under 30MB. Matching this exactly stops Instagram from stretching or auto-cropping your image in unpredictable ways.
Why does my Reels cover look cropped on my profile grid?
Instagram displays profile grid thumbnails in roughly a 3:4 rectangle, not the full 9:16 shape of the actual reel, so it slices off a portion from the top and bottom of your cover. Keep your logo, face, or key text in the middle 55 to 60 percent of the frame so it survives both views.
Should I use a custom cover or let Instagram pick one automatically?
Always upload a custom cover. Instagram's auto-grabbed frame usually comes from the first second or two of your video, which tends to be a half-formed expression or a shaky opening frame rather than anything you would choose deliberately.
Can I use the same cover size for Reels and regular Instagram posts?
No. Standard feed posts are typically 1080 x 1080 (square) or 1080 x 1350 (portrait), while Reels covers need the full 1080 x 1920 vertical ratio. Uploading a square image as a Reels cover gets it cropped or letterboxed rather than displayed as intended.
