A video can look sharp in your camera roll and still feel poorly framed on Instagram. The usual culprit is not the footage. It is the canvas. This Instagram video dimensions guide helps you choose the right frame before you trim, add text, or export, so your content uses more of the screen without cutting off the important part.
For most creators, the fastest decision is simple: use vertical 9:16 for Reels and Stories, then create a separate crop only when a feed post needs it. That approach gives you a strong starting point without forcing every clip into a one-size-fits-all export.
Instagram Video Dimensions at a Glance
Instagram supports several video shapes, but the formats below cover the work most creators, freelancers, and small businesses actually publish.
| Instagram format | Recommended dimensions | Aspect ratio | Best use | | --- | --- | --- | --- | | Reels | 1080 x 1920 pixels | 9:16 | Short-form vertical video, tutorials, product clips, creator content | | Stories | 1080 x 1920 pixels | 9:16 | Time-sensitive updates, links, polls, behind-the-scenes clips | | Portrait feed video | 1080 x 1350 pixels | 4:5 | Feed posts that need more screen space than a square | | Square feed video | 1080 x 1080 pixels | 1:1 | Simple product posts, graphics, reposted clips | | Landscape feed video | 1080 x 608 pixels | About 1.91:1 | Wide scenes, presentations, desktop footage | | Live video | 1080 x 1920 pixels | 9:16 | Vertical live sessions and interviews |
Pixels tell Instagram how much image information you are supplying. The aspect ratio tells it the shape of the frame. Both matter. A high-resolution horizontal video does not become a strong Reel just because it has plenty of pixels. If the ratio is wrong, Instagram must crop it, add empty space, or present it less prominently.
Use 9:16 for Reels and Stories
Reels and Stories are built for a full-screen phone experience. Export them at 1080 x 1920 pixels, which is a 9:16 vertical frame. This is the safest choice when your goal is reach, quick viewing, or a clear mobile-first presentation.
The main trade-off is composition. A clip shot wide or horizontally may lose key details when forced into a vertical crop. Before exporting, make sure faces, products, captions, and demonstrations sit near the center of the frame. If your subject is at the far left or right, a 9:16 crop can turn a useful shot into a confusing one.
Leave breathing room at the top and bottom as well. Instagram places interface elements over Reels and Stories, including account details, captions, buttons, and reply areas. There is no single safe-zone measurement that works perfectly for every placement because the interface can change, but the practical rule holds: keep essential text and logos away from the outer edges. Put the main message in the middle portion of the screen, then preview it on a phone before publishing.
Plan text before you edit
Captions burned into a video should be readable without fighting Instagram's controls. Use a large, high-contrast type treatment and avoid placing key words at the very bottom. If you are creating a tutorial, split a long instruction into short on-screen steps instead of squeezing a paragraph into one frame.
For a talking-head Reel, frame the speaker from the chest or waist up and leave enough open space for a headline. For a product demo, show the product large enough to understand at a glance. Full-screen vertical is valuable because it removes distractions, but it also makes weak framing more obvious.
Choose 4:5 When the Feed Is the Priority
A portrait feed video at 1080 x 1350 pixels uses a 4:5 ratio. It is shorter than a Reel but taller than a square post, giving you more visible space in the feed. This is often a good option for product clips, customer highlights, before-and-after posts, or a short video that needs to sit naturally beside static feed content.
Choose 4:5 when the feed post itself is the destination. It can give the video a more deliberate, editorial feel, particularly when the opening frame must work as a clean thumbnail. It is also useful when your original footage was shot vertically but does not have enough headroom for a full 9:16 layout.
Do not assume one crop will work everywhere. A 4:5 feed post repurposed as a Reel may show blank space or require reframing. Conversely, a 9:16 Reel placed in the feed may crop awkwardly in the preview. Make separate versions when the first second, headline placement, or product framing matters to the post's performance.
Square video at 1080 x 1080 remains useful, especially for simple announcements and graphic-led posts. However, it takes up less vertical room in the feed than 4:5. Landscape video can work for wide demonstrations, screen recordings, scenic footage, and presentations, but it generally feels smaller on a phone. Use it because the content needs width, not because it is the easiest export from your camera.
Start With the Original Footage, Not the Crop
The best export begins with the source clip. If you know a video is for Reels, shoot vertically whenever possible. Hold the phone upright, keep the subject centered, and avoid fast movements near the edges. You will spend less time rescuing the composition later.
When you only have horizontal footage, decide what must remain visible before you crop. A close-up interview may convert well to vertical because the speaker can stay centered. A wide group shot may not. In that case, consider using a 4:5 or landscape feed video instead of creating a Reel that cuts people out.
Screen recordings need a different decision. A vertical crop can make desktop menus and small text hard to read. If the screen is the main subject, crop tightly around the action, enlarge the relevant area, or use a landscape feed format. If you also need a Reel, make a separate vertical version with short zoomed-in sections rather than shrinking the entire screen into a tall frame.
A Practical Export Workflow
Start with one destination. Pick Reels, Stories, or feed video before you edit the clip. Then choose the matching canvas size and place the focal point where it will still be visible after Instagram adds its interface.
Next, trim the opening. The first second should establish what viewers are looking at: a finished result, a clear action, a useful claim, or a recognizable person. Then add captions or a short headline only where they improve comprehension. More text is not automatically more useful.
Preview before exporting. Watch once with sound and once without it. Check that the subject stays inside the frame, text remains readable, and any quick cuts do not feel abrupt. If the video is shaky, dark, noisy, or slightly off-color, make measured adjustments. A cleaner result can help, but aggressive processing can introduce an artificial look or make compression more noticeable.
For a browser-based short-video workflow, MikeSullyTools' AI Video Studio can help you trim, tune, preview, and export a social-ready version without opening a heavyweight editor. Start with the format you need, use a simple preset if it fits, adjust only what the preview shows needs attention, and export after checking the full frame.
Keep File Choices Simple
MP4 is the practical export choice for most Instagram videos. Use a common video codec such as H.264, and keep your resolution aligned with the final format rather than exporting an oversized file just because your editor allows it. Instagram will process uploaded video, so a huge file does not guarantee a better-looking post.
Frame rate depends on your source. If the footage was recorded at 30 frames per second, exporting at 30 is usually sensible. If it was shot at 60 frames per second for smooth motion or slow motion, preserve that only when the edit benefits from it. Changing frame rates without a reason can create motion that looks less natural.
Audio deserves a quick check, too. Make sure speech is clear, music does not overpower the voice, and the opening does not begin in silence unless that pause is intentional. Dimensions get the video displayed correctly; pacing and sound give people a reason to keep watching.
The right Instagram size is the one that protects the story in your clip. Pick the destination first, frame the important details for that screen, preview the result, and export a version that looks intentional rather than merely resized.
