The maximum length for videos uploaded to the reel on Postreel is 3 minutes. This means you can share videos up to 3 minutes long to engage your audience with longer-form content. Whether it's a tutorial, a vlog, a music video, or any other creative expression, you have the flexibility to showcase your ideas and stories within this time frame. Remember to make the most of those 3 minutes to captivate your viewers and make a lasting impression.
