Every LinkedIn Post Format Explained: Which to Use When

Text-only posts are the foundation of LinkedIn content. They are the fastest to create, the easiest to consume, and consistently perform well for engagement. Text posts work best for stories, opinions, frameworks, and career lessons. They are the simplest format to test new ideas because there is no production overhead. Keep text posts between 150–300 words (sweet spot for dwell time without losing attention). Use generous white space — one to two sentences per paragraph — for mobile readability.

Image posts combine a text caption with a visual. The image expands the post's visual footprint in the feed, attracting more initial attention. Best uses: infographics, charts, screenshots, quotes overlaid on branded backgrounds, or photos from events/workplaces. The image should add information that the text alone does not convey — do not add a stock photo that is merely decorative. The text caption should be able to stand alone; the image should enhance, not carry, the message.

Carousel posts (document posts) are multi-slide PDFs that users swipe through. They consistently receive the highest engagement rates on LinkedIn because each swipe is a dwell-time signal to the algorithm. Best uses: step-by-step guides, frameworks, lists, before/after comparisons, and educational content. Create carousels at 1080x1350 pixels. Limit to 8–12 slides. Put a hook on slide 1, one idea per subsequent slide, and a call-to-action on the final slide. Use large, readable fonts (minimum 24pt).

Video posts work best for demonstrations, walkthroughs, behind-the-scenes content, and personal addresses to your audience. LinkedIn's algorithm currently gives video posts initial reach boosts but video requires higher production quality to maintain audience attention. Keep videos under 90 seconds for LinkedIn feeds. Add captions (85% of LinkedIn videos are watched without sound). Square (1:1) or portrait (4:5) format maximises screen real estate on mobile. Talking-head videos with clean audio and good lighting perform best.

Polls and other formats: polls drive high interaction but low-quality engagement — good for visibility, limited for thought leadership. Use polls to surface audience opinions on genuinely interesting questions, not for trivial choices. LinkedIn newsletters allow long-form content delivered to subscribers' inboxes — good for deep-dive analysis and building a subscriber base. LinkedIn articles (blog-format) work for evergreen, search-optimised content but receive less feed distribution than native posts. Events and LinkedIn Live suit real-time engagement for webinars and AMAs.
