What is an Instagram Post?
An Instagram Post is content published to your main profile grid. These can be:
- Static images — ideal for photography, product shots, or graphic announcements.
- Carousels — swipeable sequences of multiple images or videos, perfect for storytelling or showing product variations.
- Videos — up to 60 seconds in square, landscape, or portrait formats (longer videos now appear as standard posts since IGTV’s discontinuation).
Key qualities:
- Appears permanently on your profile grid (unless deleted).
- Primarily shown in followers’ home feeds.
- Best suited for evergreen content, polished branding, and important announcements.

What is an Instagram Reel?
Instagram Reels are short, vertical videos designed to entertain, inform, and be easily discovered — similar to TikTok clips. They offer:
- Full-screen vertical playback (9:16 ratio).
- Up to 90 seconds duration.
- Appear in the Reels tab, Explore feed, followers’ feeds, and optionally your profile grid.
- Creative editing options including AR effects, captions, audio overlays, transitions, and multi-clip assembly.
Reels are highly effective for reaching audiences beyond your existing followers and riding the wave of trending sounds or challenges.

| Length | Images or video up to 60 seconds | Video up to 90 seconds |

Algorithm Reach & Engagement Differences
Instagram’s algorithm treats Posts and Reels differently:
- Posts are weighted toward your current followers. Regular engagement (likes, comments, saves) can extend reach via hashtags and shares, but growth tends to be steady rather than explosive.
- Reels are prioritized for discovery. They’re pushed into Explore and Reels feeds for viewers who have never seen your content before, based on interest signals from their past activity.
If your aim is rapid audience growth, Reels often deliver. But for relationship-building and brand storytelling, Posts remain important.

Purpose and Typical Use Cases for Posts
Posts shine when:
- Branding is a priority — cohesive, curated visuals.
- Announcements need a permanent home.
- Evergreen content like tutorials, portfolios, and inspirational images are shared.
- Sequential stories benefit from carousel format.
They’re also easier to produce without heavy video editing resources.

Purpose and Typical Use Cases for Reels
Reels excel for:
- Trend participation via popular audio and challenges.
- Discovery campaigns to reach entirely new audiences.
- Behind-the-scenes insight into your team or process.
- Micro tutorials and quick hacks that hook attention fast.
If tapping into current culture is part of your strategy, Reels are your go-to format.
