Instagram Video Size Specifications for 2026

A solid grasp of Instagram video size specifications is fundamental to producing content that appears polished and gains algorithmic traction. Instagram Reels dimensions call for 9:16 vertical orientation at 1080x1920 pixels, which is also the standard Instagram story size. Feed posts offer three layout choices: square (1:1) at 1080x1080, portrait (4:5) at 1080x1350, and landscape (1.91:1) at 1080x566. Each ratio fills a distinct creative role. Reels and Stories consume the entire mobile viewport, driving maximum viewer attention. Portrait feed clips take up more vertical scroll space than square entries, while landscape is tailored for widescreen and cinematic content. Our Instagram video resizer bundles all of these formats as instant-access presets, eliminating the need to manually calculate pixel values. Keeping current with the correct Instagram video size guarantees your content renders precisely as designed, free from unintended cropping or quality degradation by the platform.

Step-by-Step Guide to Resizing Videos for Instagram

Operating our Instagram video resizer is intuitive and requires only a handful of steps. Begin by dragging your video file into the upload zone, or click to navigate your file system. The tool handles MP4, WebM, MOV, and AVI files up to 500MB in size. After your clip loads, you will see a playback preview together with metadata about its current resolution, weight, and running time. Then choose your target Instagram format from the four available presets: Reels/Stories (9:16), Feed Square (1:1), Feed Portrait (4:5), or Feed Landscape (1.91:1). If the ratio conversion requires cropping, use the crop position tool to specify which region of the frame to preserve. A live preview illustrates the exact composition of the final output. Press the Resize for Instagram button, and the tool transforms your video locally using your browser's GPU acceleration. Within moments, your adapted video is available for download and direct upload to Instagram.

How Instagram Video Dimensions Drive Higher Engagement

The Instagram video dimensions you select have a measurable effect on content performance. Clips that align with the native aspect ratio for their designated placement earn preferential treatment from the algorithm because they deliver a superior viewing experience. When you resize video for Instagram using the proper dimensions, your material fills the mobile viewport completely, removing jarring black bars and awkwardly cropped subjects. Instagram Reels dimensions of 9:16 carry particular weight because Reels span the full display, and any format mismatch sacrifices valuable visual territory. Portrait feed clips at 4:5 command 20% more vertical real estate than square posts, which correlates with longer dwell times and elevated engagement rates. Research indicates that correctly sized Instagram video content attracts meaningfully more likes, comments, and shares than clips that display cropped or improperly formatted. Applying our free Instagram resizer to nail the right dimensions before uploading is among the most effective, low-effort optimizations for boosting your content's reach.

Instagram Reels Dimensions and Optimization Tips

Instagram Reels now serve as the platform's primary vehicle for content discovery, which makes nailing the Instagram Reels dimensions essential. The target specification is 1080 pixels across by 1920 pixels tall, producing a 9:16 vertical aspect ratio that spans the full smartphone viewport. This is identical to the Instagram story size, so material sized for one format transfers seamlessly to the other. When you run your content through our Instagram video resizer for Reels preparation, the tool locks in these exact pixel values automatically. For creators working with landscape or other non-portrait source footage, the precision crop feature lets you govern exactly which segment of the original frame survives the conversion. Position critical visual elements and overlay text inside the center-safe region, since Instagram UI components like the heart icon, comment button, and share control occupy the screen edges. Reels support durations from 15 to 90 seconds with a ceiling of 4GB per file. Our tool manages the dimensional formatting so you can devote your energy to crafting engaging content that connects with your target audience.

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

Instagram feed content supports three separate aspect ratios, each designed for distinct creative applications. Square clips at 1:1 (1080x1080) represent the heritage Instagram format and perform consistently across a broad range of content categories, from product demonstrations to lifestyle clips. Portrait clips at 4:5 (1080x1350) have gained substantial popularity because they claim additional vertical territory in the feed, which inherently captures greater attention and sustains viewer engagement for longer periods. Landscape clips at 1.91:1 (1080x566) are purpose-built for cinematic sequences, travel documentaries, or any footage where an expansive field of view strengthens the narrative. Our Instagram video resizer streamlines format switching with minimal effort. Upload your clip once, select a preset, fine-tune the crop alignment, and export. If you want to experiment with which aspect ratio resonates most with your followers, you can rapidly resize the same video into multiple Instagram video sizes. The crop position selector ensures your subject stays centered and properly composed regardless of the output dimension you select, providing creative versatility without any technical friction.

In-Browser Privacy: How Our Instagram Video Resizer Safeguards Your Content

Data privacy is an escalating priority for content creators, and our Instagram video resizer tackles this concern head-on with a fully client-side architecture. In contrast to cloud-hosted tools that demand you upload footage to remote infrastructure, our resizer executes every operation locally on your machine. Your video file is decoded by the browser, transformed using Canvas and MediaRecorder APIs, and the final output is assembled without a single byte of data leaving your device. This eliminates any possibility of unreleased content being cached on third-party servers, captured during network transit, or viewed by unauthorized individuals. For brands handling sensitive pre-launch campaign videos, influencers developing exclusive material, or anyone who prioritizes digital security, this design delivers authentic peace of mind. The free Instagram resizer operates completely offline after the initial page load, meaning you could disable your internet connection before processing for absolute certainty. No tracking cookies monitor your activity, no analytics platform logs which videos you process, and no login credentials are required to unlock any capability.

Expert Tips for Maximizing Results with Our Free Instagram Resizer

To extract peak performance from our Instagram video resizer, begin with the sharpest source material available. Footage captured at 1080p or above yields the crispest output when adapted to any Instagram video dimensions. If your source clip already has a vertical orientation and you need Instagram Reels dimensions, the conversion may involve only minimal cropping. For landscape-to-portrait transformations, give careful consideration to the crop position setting. Always review the preview before initiating processing to confirm your subject is well-framed. When preparing Instagram feed video in portrait (4:5) ratio, center-crop delivers strong results for most content, though scenes featuring people may benefit from top-crop to keep faces visible. For widescreen landscape feed entries, verify that essential visual elements are not truncated at the margins. Consider generating multiple versions of high-value videos at different Instagram video sizes so you can distribute identical content across Reels, Stories, and feed with each placement receiving its optimal format. As a final note, our free Instagram resizer exports in WebM format, which Instagram accepts natively. You can resize and publish without requiring any intermediate conversion steps.
