LinkedIn Post Size Guide: Best Dimensions for Engagement

On LinkedIn, how you present your content can be just as important as what you’re saying. Whether it’s a post, an image, or a video, the size and format you choose play a big role in how your audience interacts with it. Clean visuals, properly sized graphics, and mobile-friendly layouts are key to grabbing attention as people scroll.

Getting the dimensions right helps your content look polished, load correctly, and drive more clicks, shares, or reactions. It’s a simple detail that often gets overlooked, but it can make a big difference in how your message performs.

If you’re sharing content on LinkedIn and want it to stand out, understanding the ideal post sizes is a great place to start.

What Is The Ideal LinkedIn Post Size?

Optimizing the size of your LinkedIn posts enhances their impact and visibility. Text-based posts typically perform well when limited to 150–200 words, as concise messaging captures attention in busy feeds. Posts exceeding 1,300 characters, LinkedIn's limit before truncation, may lose engagement if key points aren't emphasized early.

Image dimensions matter too. Use a recommended size of 1200 x 627 pixels for horizontal visuals or 1080 x 1080 pixels for square formats. This ensures your images display correctly across devices without distortion.

For video posts, aim for lengths between 30 seconds and 3 minutes. Videos under 90 seconds generally outperform longer ones, delivering your message efficiently. Ensure video resolution is at least 1080 x 1920 pixels to maintain quality.

When using documents, such as PDFs, maintain concise layouts with 5-10 slides. Avoid cluttered designs and use clear fonts for easy readability. Adhering to these size guidelines increases reach and interaction with your LinkedIn audience.

Text Post Length Guidelines

LinkedIn allows text posts up to 3000 characters, offering ample room to share detailed insights or professional updates. To enhance engagement, balancing this length with concise, high-impact content is essential.

Character Limits For LinkedIn Posts

On LinkedIn, text posts can reach a maximum of 3000 characters, while comments have a limit of 1250 characters. This flexibility lets you craft messages from brief updates to more detailed narratives.

Optimal Length For Engagement

While extended text posts are possible, audience engagement typically favors concise content. Posts between 150–200 words often perform well, combining clarity and brevity to maintain reader interest.

Image And Video Post Dimensions

Visual content plays a key role in achieving higher engagement on LinkedIn posts. Following recommended dimensions ensures your images and videos appear clear and professional across devices.

Recommended Image Sizing

Square images should measure 1080 x 1080 pixels, ensuring balanced visual appeal. Use 1200 x 627 pixels for landscape images to fit LinkedIn's feed seamlessly. Portrait images, at 627 x 1200 pixels, deliver optimal vertical display. Feature 1200 x 644 pixels for article headers, while carousel ads benefit from 1080 x 1080 pixels.

Best Practices For Video Dimensions

Maintain a resolution between 256 x 144 pixels and 4096 x 2304 pixels, adjusting to fit your content's needs. For better performance, keep your video aspect ratio at 16:9, as it offers the smoothest playback experience. Short videos under 90 seconds typically attract more attention and ensure higher retention rates.

LinkedIn Carousel And Document Post Sizes

LinkedIn carousel and document posts are effective tools for presenting detailed, visually engaging content. Using the correct dimensions and formats ensures your posts display and professionally.

Understanding Carousel Post Specifications

Carousel posts allow you to showcase multiple images or slides, each with its own message. Use image dimensions of 1080 x 1080 pixels (square) or 1200 x 627 pixels (landscape) to maintain visual consistency across slides. Stick to these sizes to avoid cropping or distortion when users swipe through your content.

Document Upload Size Considerations

LinkedIn supports document uploads of up to 300 pages and 100 MB. Accepted formats include PDF, PPT, PPTX, DOC, and DOCX. Ensure your content remains professional and readable by using concise layouts, clear fonts, and a logical structure. This guarantees effective delivery of your message to your audience.

Tips For Maximizing Engagement With LinkedIn Posts

Creating engaging LinkedIn posts isn’t just about what you say. It also depends on how you present it, when you share it, and how your audience connects with the message. Here are some simple and effective ways to increase interaction and visibility:

• Write With Clarity and Purpose
  Keep your content relevant, professional, and easy to understand. A clear structure and concise wording help your message come across effectively. Tools like Typoro can help you write, format, and schedule posts that are polished and ready to perform well.

• Use Eye-Catching Visuals
  Posts with visuals attract more attention. Add high-quality images, short videos, or infographics to make your content more engaging. Square images (1080 x 1080 pixels) and short videos under 90 seconds tend to get the best results.

• Add a Clear Call to Action
  Boost engagement by encouraging your audience to interact. Ask questions, invite opinions, or link to related content to prompt responses and create conversation.

• Post at the Right Time
  Timing matters. Share content when your audience is most active, such as during work hours or lunch breaks, to increase visibility and interaction.

• Engage With Your Audience
  Be active in the comments. Replying to questions or reactions shows you're present and builds stronger connections with your network.

Putting care into your content, visuals, and timing helps your posts perform better. By staying consistent and thoughtful with your approach, you can turn LinkedIn into a valuable space for conversation and growth.
