With over a billion active users and an ever-growing library of dynamic content, Instagram has become a powerhouse platform for brands, influencers, and marketers alike. However, to unlock the full potential of video content on Instagram, it’s crucial to understand the platform’s video format requirements. From resolution to aspect ratio and file size, adhering to Instagram’s technical specifications ensures your content not only looks professional but also performs at its best. This guide will serve as your ultimate cheat sheet to simplify Instagram video formatting.
Understanding Instagram’s Video Ecosystem
Instagram currently supports several types of video content, each with its own specifications:
- Feed videos – visible on your profile and followers’ feeds
- Stories – short videos lasting 24 hours unless saved
- Reels – entertaining, short-form videos
- IGTV – for long-form content (less emphasized since late 2021)
- Live – streamed in real-time, generally not as format-restricted
Each format supports different video specifications. Knowing these differences can help avoid poor-quality uploads, awkward cropping, or unexpected failures during upload.
Video Resolution Guidelines
Resolution refers to the number of pixels in each dimension of your video. High-resolution videos look sharper and more professional. Instagram supports HD video at 1080p resolution. However, depending on the video type, minor differences exist.
- Feed and Reels: Optimal resolution is 1080 × 1350 pixels (portrait), though square videos at 1080 × 1080 are also acceptable.
- Stories: Full-screen vertical format with a resolution of 1080 × 1920 pixels.
- IGTV: Also supports 1080 × 1920 pixels, suitable for full-screen vertical view.
- Live: Broadcast live in 720 × 1280 or higher; auto-adjusted based on connection speed.
Tip: Always export your videos in 1080p for optimal playback, as lower resolutions may appear blurry or pixelated once compressed by Instagram.
Aspect Ratio Explained
Aspect ratio defines the proportional relationship between your video’s width and height. Choosing the right ratio not only maximizes screen space but also affects readability and engagement. Here are the recommended aspect ratios for each format:
- Feed Videos:
- Square – 1:1
- Portrait – 4:5
- Landscape – 1.91:1
- Stories and Reels: 9:16 (vertical)
- Live: Fixed at 9:16
Instagram prioritizes vertical content, especially for Reels and Stories, as it fills the screen on mobile devices, which is how most users engage with the platform.

File Size and Duration
Uploading videos beyond Instagram’s technical limits can result in failed uploads or reduced video quality due to compression. To make your uploads smoother, here’s a breakdown of file size and duration restrictions:
- Feed Videos: Max file size is 4GB. Duration must be 3 to 60 seconds.
- Stories: Each segment is limited to 15 seconds, but you can stitch together multiple stories for longer content.
- Reels: Duration can be up to 90 seconds.
- IGTV:
- Minimum duration: 1 minute
- Maximum: 15 minutes (mobile uploads) or 60 minutes (via web)
- Live Videos: Previously limited to 1 hour, now can last up to 4 hours.
When preparing your video for upload, keeping your file size under 1GB is ideal. Large files require more time to upload and are more likely to be compressed, potentially reducing quality.
Best Video Format and Codec
Instagram recommends using specific video formats to ensure maximum compatibility and quality. The following settings are considered optimal:
- Container: MP4 (.mp4)
- Codec: H.264
- Audio: AAC at 44.1 kHz
- Bitrate: Variable, but typically around 3,500 kbps is ideal
Note: Avoid MOV or AVI files unless absolutely necessary, as they may reduce compatibility or increase upload times.
Keeping Compression in Mind
Instagram automatically compresses videos to meet its optimization protocols. While this helps conserve bandwidth on mobile, it can sometimes deteriorate quality. Follow these guidelines to minimize compression:
- Always export in 1080p resolution.
- Stick to recommended aspect ratios to prevent cropping.
- Use a high bitrate when exporting (above 3,000 kbps).
- Avoid re-uploading videos that have already been compressed.

Tips for Consistent Video Quality
Maximizing video quality is not just about adhering to technical specifications. It’s also about how you produce and manage your content before posting. Follow these best practices for polished, consistent videos:
- Record natively at 1080p or higher – Avoid using cameras or devices that provide low-res output.
- Edit within specialized software – Tools like Adobe Premiere Pro, Final Cut Pro, or even mobile apps like InShot come with presets for Instagram formats.
- Include automated captions – Especially useful for Stories and Reels to maximize engagement with viewers who watch without sound.
- Design with mobile in mind – Use larger text, centralize important elements, and consider screen-safe areas.
