Instagram isn't a one-size-fits-all platform for video. Each format—from the main feed to the quick flash of a Story—has its own set of rules. Knowing these specifications helps your videos look their best and fit naturally into how people use the app.

Feed videos are the classic posts that appear in the main, scrollable feed. These are permanent fixtures on your profile unless you delete them. While Instagram started with a square-only format, it now supports a few different shapes.

Your video can be square (1:1), horizontal (1.91:1), or vertical (4:5). The 4:5 vertical format is often best because it takes up the most screen space in the feed without getting cut off. Videos can be anywhere from 3 seconds to 60 minutes long. For the best quality, aim for a resolution of at least 1080 pixels wide.

Stories and Reels are both designed for full-screen, vertical viewing on a phone. They are immersive and designed to be consumed quickly.

Instagram Stories are temporary posts that disappear after 24 hours unless saved to your highlights. Each individual story clip can be up to 60 seconds long. They are meant to be casual, behind-the-scenes glimpses.

Instagram Reels are short, entertaining videos, often set to music or trending audio. They're Instagram's answer to TikTok. Reels can be up to 90 seconds long and are a key way for accounts to be discovered by new audiences.

For both Stories and Reels, the technical specs are the same.

Choosing the right format depends on your goal. A polished, longer video might belong in the feed, while a quick, fun clip is perfect for Reels. Here’s a quick breakdown of the key specs.

A note on IGTV: Instagram has mostly phased out the standalone IGTV brand. Longer videos that would have been IGTV content are now simply part of the main feed as regular Instagram Video posts, which is why the feed can accommodate videos up to 60 minutes long.

By tailoring your video to fit these formats, you ensure it looks professional and is easy for your audience to watch.
