Key takeaways
- Threads videos can run up to 5 minutes (about 1GB max file size), but the platform is reported to rank on completion rate — 15 seconds to 1 minute is the recommended range for reach.
- Platforms change these limits without much notice — treat this as a checkpoint, not a permanent guarantee.
Threads video length limit: the technical limit
- Maximum video length: 5 minutes per upload
- Maximum file size: roughly 1GB
- One video per post — Threads carousels stay images-only
Why the maximum length usually underperforms
Because Threads is reported to weight completion rate heavily, a short clip watched all the way through commonly outperforms a much longer one most viewers drop out of early — the 5-minute ceiling exists for creators who need it, not as a target to hit by default.
