The Ultimate Guide to LinkedIn Post Image Sizes: Stop the Scroll, Boost Your Reach

Picture this: You’ve spent hours crafting the ultimate thought-leadership post. You’ve refined your hook, polished your insights, and added a striking visual to pull readers in. You hit publish, feeling confident. But when you check the post on your phone, disaster strikes: your carefully designed graphic is awkwardly cropped, your headline text is cut off, and the image looks blurry or pixelated.

On a professional platform like LinkedIn, visual presentation matters. Poorly formatted images signal carelessness, while crisp, perfectly dimensioned visuals command authority and stop the scroll.

Whether you’re sharing a single feed image, building a multi-slide carousel, or upgrading your profile presence, here is everything you need to know about mastering LinkedIn post image sizes.

1. Single Image Feed Posts: Choosing Your Format

LinkedIn supports three main aspect ratios for standard feed images. Choosing the right one depends entirely on the type of content you are sharing and where your audience is viewing it.

Portrait / Vertical (1080 x 1350 pixels — 4:5 Aspect Ratio)

• The Engagement Winner: Portrait orientation takes up the most vertical real estate on mobile feeds, where more than 60% of LinkedIn users consume content.
• Best Used For: Tall infographics, step-by-step visual guides, breakdowns, and high-impact announcements.
• Pro Tip: Stick strictly to the 4:5 ratio (1080 x 1350 px). If you upload an overly tall image (like a 9:16 Instagram Story format), LinkedIn will automatically crop it from the bottom, potentially hiding critical details or text.

Square (1080 x 1080 or 1200 x 1200 pixels — 1:1 Aspect Ratio)

• The Safe All-Rounder: If you aren’t sure which layout to choose, square is your best default. It renders cleanly and predictably on both desktop monitors and mobile screens without unexpected cropping.
• Best Used For: Quote graphics, data visualizations, clean product shots, and single-topic insight cards.

Landscape / Horizontal (1200 x 627 pixels — 1.91:1 Aspect Ratio)

• The Traditional Choice: This is LinkedIn’s classic link-preview format and standard landscape view. While it works fine on wide desktop screens, it takes up minimal vertical space on mobile devices, making it easier for users to scroll right past it.
• Best Used For: Sharing external blog post links, wide-angle photography, or horizontal banner graphics where text isn’t the primary focus.

2. Carousels and Document Posts (PDFs)

LinkedIn document posts—often referred to as carousels—consistently rank among the highest-performing content types on the platform, frequently generating two to three times the engagement of standard text or single-image updates.

• Recommended Slide Dimensions:
  • Square: 1080 x 1080 pixels (1:1 ratio)
  • Portrait: 1080 x 1350 pixels (4:5 ratio)
• Format: Upload your carousel slides as a PDF document rather than individual images or native PowerPoint files to ensure text sharpness and formatting consistency.
• Specs: Keep your file size under 100 MB, and aim for 5 to 10 slides to maintain high completion rates.

3. Video Post Dimensions

Video content continues to expand its footprint on professional feeds. If you are uploading native videos, match your dimensions to your creative intent:

• Square: 1080 x 1080 pixels (1:1)
• Landscape: 1920 x 1080 pixels (16:9 HD standard)
• Portrait / Vertical: 1080 x 1920 pixels (9:16) for immersive, full-screen mobile viewing
• File Limits: Up to 5 GB and anywhere from 3 seconds to 10 minutes in length (MP4 format recommended).

4. Don’t Forget Your Profile and Banner Dimensions

Your content image is only half the battle; your overall profile or company page layout sets the baseline for your professional credibility.

• Personal Profile Picture: 400 x 400 pixels (1:1 square, cropped into a circle by LinkedIn)
• Personal Cover / Banner Photo: 1584 x 396 pixels (4:1 ratio)
  • Pro Tip: On mobile, LinkedIn aggressively crops the outer edges of your personal banner, and your circular profile picture overlaps the bottom-left corner. Keep your key branding and text elements centered safely.
• Company Page Cover Photo: 1128 x 191 pixels

Quick Technical Checklist for Flawless LinkedIn Visuals

1. File Formats: Use PNG for graphics, charts, and images containing text (to keep text crisp and prevent compression artifacts). Use JPEG or WebP for real-life photographs.
2. File Size Limits: Keep single feed images under 5 MB to ensure fast loading times across network conditions (though LinkedIn technically permits up to 10 MB in some formats).
3. Color Space: Design your graphics in RGB color mode rather than CMYK to ensure colors display accurately on digital screens.
4. Always Preview: Before pushing your post live to thousands of professionals, upload it as a draft or preview it on both a desktop monitor and a mobile phone. A quick five-second check can save you from an awkward crop or unreadable typography.
