Instagram Video Size Requirements in 2026

Understanding Instagram video size requirements is essential for creating content that looks professional and performs well in the algorithm. Instagram Reels dimensions are 9:16 vertical at 1080x1920 pixels, which is also the standard Instagram story size. For feed posts, you have three options: square (1:1) at 1080x1080, portrait (4:5) at 1080x1350, and landscape (1.91:1) at 1080x566. Each format serves a different purpose. Reels and Stories occupy the full screen on mobile devices, maximizing viewer engagement. Portrait feed videos take up more real estate in the scroll than square posts, while landscape is best for cinematic or wide-angle content. Our Instagram video resizer includes all of these formats as one-click presets, so you never have to calculate pixel dimensions manually. Staying on top of the correct Instagram video size ensures your content is displayed exactly as intended, with no unexpected cropping or quality reduction by the platform.

How to Resize Videos for Instagram Step by Step

Using our Instagram video resizer is straightforward and takes just a few steps. First, drag and drop your video file onto the upload area, or click to browse your files. The tool accepts MP4, WebM, MOV, and AVI formats up to 500MB. Once your video loads, you will see a preview along with details about its current resolution, file size, and duration. Next, select your desired Instagram format from the four presets: Reels/Stories (9:16), Feed Square (1:1), Feed Portrait (4:5), or Feed Landscape (1.91:1). If the aspect ratio change requires cropping, use the crop position selector to choose which part of the frame to keep. A live preview shows you exactly how the final video will appear. Click the Resize for Instagram button, and the tool processes your video locally using your browser's hardware acceleration. Within moments, your resized video is ready to download and upload directly to Instagram.

Why Instagram Video Dimensions Matter for Engagement

The Instagram video dimensions you choose directly impact how your content performs. Videos that match the native aspect ratio for their placement receive favorable treatment from the algorithm because they provide a better viewing experience. When you resize video for Instagram with the correct dimensions, your content fills the screen properly on mobile devices, eliminating distracting black bars or cropped subjects. Instagram Reels dimensions of 9:16 are particularly important because Reels occupy the entire screen, and any deviation means lost visual real estate. Portrait feed videos at 4:5 take up 20% more vertical space than square posts, which translates to longer scroll-stop times and higher engagement rates. Studies show that properly sized Instagram video content receives significantly more likes, comments, and shares compared to videos that appear cropped or poorly formatted. Using our free Instagram resizer to match the right dimensions before uploading is one of the simplest ways to improve your content's performance.

Instagram Reels Dimensions and Best Practices

Instagram Reels have become the platform's primary discovery format, making it critical to get the Instagram Reels dimensions right. The recommended size is 1080 pixels wide by 1920 pixels tall, creating a 9:16 vertical aspect ratio that fills the entire smartphone screen. This is the same dimension used for Instagram story size, so content resized for one format works perfectly for the other. When you use our Instagram video resizer to prepare Reels content, the tool automatically applies these exact pixel dimensions. For creators who shoot in landscape or other non-vertical formats, the smart crop positioning feature lets you control exactly which portion of the original frame is preserved. Keep important visual elements and text within the center-safe zone, as Instagram overlays such as the like button, comments, and share icons appear along the edges. Reels can be between 15 and 90 seconds long with a maximum file size of 4GB. Our tool handles the dimension aspect while you focus on creating compelling content that resonates with your audience.

Resize Video for Instagram Feed: Square, Portrait, and Landscape

Instagram feed videos offer three distinct aspect ratios, each suited to different types of content. Square videos at 1:1 (1080x1080) are the classic Instagram format and work reliably for most content types, from product showcases to personal clips. Portrait videos at 4:5 (1080x1350) are increasingly popular because they occupy more vertical space in the feed, which naturally draws more attention and keeps viewers engaged longer. Landscape videos at 1.91:1 (1080x566) are ideal for cinematic footage, travel content, or any video where a wide field of view adds to the storytelling. Our Instagram video resizer makes switching between these formats effortless. Upload your video once, select a format, adjust the crop position, and download. If you want to test which aspect ratio performs best for your audience, you can quickly resize the same video into multiple Instagram video sizes. The crop position selector ensures that your subject remains in frame regardless of which dimension you choose, giving you creative flexibility without any technical complexity.

Browser-Based Privacy: How Our Instagram Video Resizer Protects Your Content

Privacy is a growing concern for content creators, and our Instagram video resizer addresses this directly with a fully browser-based architecture. Unlike cloud-based tools that require you to upload your videos to remote servers, our resizer processes everything locally on your device. Your video file is read by your browser, resized using Canvas and MediaRecorder APIs, and the output is generated without any data ever leaving your machine. This means there is zero risk of your unreleased content being stored on third-party servers, intercepted during transfer, or accessed by unauthorized parties. For brands working with confidential product launch videos, influencers preparing exclusive content, or anyone who values digital privacy, this approach offers genuine peace of mind. The free Instagram resizer works entirely offline once the page has loaded, so you could even disconnect from the internet before processing if you want absolute certainty. No cookies track your usage, no analytics record which videos you resize, and no account is required to access any feature.

Tips for Getting the Best Results with Our Free Instagram Resizer

To get the best output from our Instagram video resizer, start with the highest quality source footage available. Videos shot in 1080p or higher will produce the sharpest results when resized to any Instagram video dimensions. If your source video is already in a vertical orientation and you need Instagram Reels dimensions, the resizing process may only need minimal cropping. For landscape-to-vertical conversions, pay special attention to the crop position setting. Preview the result before processing to make sure your subject is well-framed. When preparing Instagram feed video in portrait (4:5) format, center-crop works well for most content, but face-tracking scenes might benefit from top-crop to keep heads in frame. For cinematic landscape feed posts, ensure key visual elements are not cut off at the edges. Consider creating multiple versions of important videos at different Instagram video sizes so you can post the same content across Reels, Stories, and feed with optimal formatting for each. Finally, remember that our free Instagram resizer outputs WebM format, which Instagram accepts directly. You can resize and upload without any additional conversion steps.
