What Are LinkedIn Post Limits?
LinkedIn post limits refer to defined boundaries on publishing frequency, text length, and media specifications within certain timeframes. Common categories include:
- Daily/Monthly Posting Caps – Maximum posts allowed in a given time period before restrictions.
- Character Limits – Upper bounds for posts, articles, comments, and headlines.
- File Size & Duration – Restrictions for images, videos, and documents.
These limits encourage creators to focus on quality over quantity—improving both user experience and content discoverability.

Media Upload Guidelines: Images, Video, and Carousel Files
Images
To boost engagement, use crisp, properly formatted visuals. The maximum upload size is 5 MB, and dimensions should match LinkedIn’s recommended 1200×627 px for feed posts.
Video
Native video uploads must be under 10 minutes and 5 GB. For longer content, edit or compress before posting. Aim for strong opening seconds to capture attention.
Carousel Documents
Carousel-style PDF posts are limited to 100 MB or 300 pages. Each slide should deliver one key insight for best retention.

Comment and Hashtag Restrictions
Comments allow up to approximately 1,250 characters—enough to add meaningful thoughts without overwhelming readers. For hashtags, the per-post limit is 30, but using 3–5 targeted hashtags can increase discoverability and avoid spam penalties.

Why LinkedIn Sets These Posting Rules
LinkedIn implements posting caps and file limits to:
- Prevent Spam – Discourages automated bulk posting or irrelevant content.
- Enhance User Experience – Keeps the feed readable and professional.
- Maintain Platform Efficiency – Large files or excessive posts strain resources.
- Preserve Community Standards – Upholds quality and authenticity.

How to Optimize Within LinkedIn’s Post Limits
You can achieve high engagement by:
- Front-Loading Value – Deliver your hook in the first 140 characters to avoid truncation.
- Multi-Format Publishing – Combine text, image, video, and carousel posts throughout the week.
- Formatting for Readability – Use bullets, short paragraphs, and selective emojis.
- Offline Drafting – Write and edit outside LinkedIn to track character counts accurately.

Scheduling Best Practices to Avoid Overposting
To stay compliant and consistent:
- Weekly Planning – Schedule 1–2 strong posts daily at most.
- Varying Content Types – Rotate formats to keep followers engaged.
- Audience Timing – Post when your target network is active (morning or midday often works).
- Use Scheduling Tools – Choose tools that respect LinkedIn’s limits.

Frequent Pitfalls That Can Trigger Restrictions
Steer clear of:
- Hashtag Overuse – Maxing out 30 hashtags regularly dilutes relevance.
- Duplicate Content – Reposting identical text in short intervals.
- Ignoring Media Guidelines – Attempting uploads beyond file size or duration limits.
- Posting Too Frequently – Overposting leads to temporary suspensions.
- Excess External Linking – May lower post visibility in the feed.
