Hard limits for Instagram Reels.
Who Is This For
Check character limits, media specs, and count restrictions for your target platform and format before posting to prevent publish failures. Make rules lookup a standard pre-publish step to increase operational accuracy.
Give your whole team a single reference for platform rules during multi-author content production to eliminate inconsistencies and rework. Use the checker to confirm all format requirements are met when publishing the same campaign across multiple platforms.
When publishing to Instagram, LinkedIn, TikTok, X, and other platforms simultaneously, quickly compare how each platform handles the same format type. Prevent partial publish failures and content truncation caused by overlooked platform differences.
About the Platform Content Rules Checker
Every social media platform enforces different hard limits on character count, media specifications, and publishing constraints. Using a rules checker before publishing helps reduce upload failures, content truncation, and spec mismatches across all your active channels.
What Is the Platform Content Rules Checker
The platform content rules checker is a reference tool organized by platform and post format, covering Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, and Reddit across major format types including feed posts, Reels, Stories, carousels, Shorts, and more. Each rule entry shows character limits, supported media types, media count limits, and publishing constraints, with source evidence links so you can verify rule accuracy directly against official documentation.
Why Pre-Publish Rule Checks Matter
Platform rules differ not just between platforms but across formats on the same platform: Instagram Feed supports up to 10 images per carousel while Reels supports only single video; LinkedIn articles and LinkedIn short posts have character limits that differ by more than tenfold. Relying on memory is error-prone, and looking up rules at the moment of publishing is a more reliable practice that prevents costly re-do cycles.
How to Use the Platform Content Rules Checker
Select your target platform such as Instagram, then choose the specific format such as Reels, and the tool displays all key rules for that combination. Multiple formats can be compared side by side to identify constraint differences within the same platform. For rules with source links, click through to verify directly against official documentation and confirm data accuracy.
Tips for Managing Multi-Platform Content Rules
Place the rules checker in a fixed position on your pre-publish checklist rather than only consulting it when problems occur. For new team members, the rules tool is an efficient resource for quickly understanding platform differences. When publishing the same content across multiple platforms, check rules individually for each platform — a single spec standard rarely applies across all channels.
Why format-level checks matter
Within the same platform, Post / Reels / Story often follow different constraints.
Catch hard-limit issues before submission.
Keep ops, design, and editors on one rules baseline.
Compare formats side by side before producing assets.
Every rule includes source links and verification date.
