Media Limits & Requirements
Let’s be real, every social platform plays by its own rules. From file sizes to video lengths to hashtag limits, keeping track of what’s allowed (and what’s not) for each platform can feel like a full-time job in itself.
That’s where Rella steps in!
We’ve put together this quick-reference guide to help you understand the current media requirements for each platform so you can create content confidently without second-guessing the specs.
Even better? When you're auto-posting with Rella, we’ll automatically flag anything that doesn’t meet the platform’s requirements before your content goes live. So if something’s too long, too large, or just not quite right, you’ll get a heads-up and have the chance to fix it before publishing.
Let’s break it all down:
