- Duration: Up to 3 minutes

Why Reels Beat Regular Posts
Instagram's algorithm heavily favors Reels over regular posts and Stories:
- Explore page exposure: Reels can reach users who don't follow you
- Dedicated Reels tab: Your content appears in a TikTok-style feed
- Higher engagement: Reels typically get 2-3x the reach of static posts
- Cross-platform potential: Same content can go to TikTok and YouTube Shorts

Optimal Reel Lengths
| Length | Best For | Notes |
|---|---|---|
| 7-15 seconds | Trending sounds, memes | High completion rate, good for loops |
| 15-30 seconds | Quick tips, showcases | Sweet spot for most content |
| 30-60 seconds | Mini tutorials, stories | Good for valuable content |
| 1-3 minutes | In-depth content | Use only if content demands it |
Shorter isn't always better, but completion rate matters. Keep it as long as it needs to be - no longer.
Crop to 9:16 — Built In
JustTrimVideo can crop your horizontal video to vertical 9:16 — no external editor needed. Load your clip and choose Crop to 9:16, Fit with bars (letterbox), or Keep original. Already shooting vertical? The tool detects it automatically and keeps your trim lossless.
