Defining Instagram Posts vs Reels
Instagram Posts refer to static images, carousels (multiple images or videos in a single post), and short videos published directly to the feed.
Reels, on the other hand, are short, dynamic vertical videos (up to 90 seconds) that appear in a dedicated Reels tab and are prominently featured in the Explore section.
Key format differences:
- Posts
- Appear on followers’ feeds and in your profile grid.
- Can include images, carousels, or videos.
- Duration: Videos can be up to 10 minutes via IGTV, though feed videos are typically shorter.
- Reels
- Designed for quick entertainment, education, or inspiration.
- Duration: 15–90 seconds.
- Optimized for Explore and Reels discovery pages.

Algorithm Differences: Feed vs Explore vs Reels Tab
Instagram's algorithms respond differently to each format based on user behaviour.
- Feed Algorithm (Posts):
- Prioritizes content from accounts users engage with frequently.
- Factors in relationships, relevance, and recency.
- Explore Algorithm (Posts):
- Surfaces content from accounts outside a user’s following list.
- Prefers highly engaging content within specific interests.
- Reels Algorithm:
- Focuses on watch time, replays, and engagement speed.
- Pushes more frequently to non-followers.
- Rewards the use of trending audio, hashtags, and creative edits.
