Optimize Shared Posts for Both Platforms
Even though the same post appears on both, Facebook and Instagram have unique content preferences.
Tips:
- Image ratios: Instagram loves square (1:1) or vertical (4:5) formats, while Facebook supports more horizontal formats (16:9).
- Caption length: Instagram captions get truncated after ~125 characters in previews—grab attention early.
- Hashtags: Instagram supports up to 30 hashtags, while Facebook hashtags have limited reach.
- Tagging: Not all @mentions translate between platforms.
| Element | ||
|---|---|---|
| Optimal Image Size | 1200×630 px | 1080×1080 px (square) |
| Max Caption Length | 63,206 characters | 2,200 characters (125 before cut‑off) |
| Hashtag Usage | Low to moderate | High, up to 30 hashtags |
| Best Formats | Links, photos, videos | Photos, videos, carousels, Reels |
