The Ultimate Guide to LinkedIn Post Image Sizes (2026 Edition)

In the professional world of LinkedIn, first impressions matter more than ever. Whether you are building your personal brand, promoting your company, or launching a targeted marketing campaign, visuals are the secret weapon to stopping the relentless scroll.

However, nothing kills professional credibility faster than a blurry, awkwardly cropped, or pixelated header image.

If you have ever uploaded an image to LinkedIn only to watch it get awkwardly chopped off at the edges, you know the frustration. To help your content stand out for all the right reasons, here is the ultimate, up-to-date guide to LinkedIn post image sizes and dimensions.

Why LinkedIn Image Sizes Matter

LinkedIn’s algorithm favors engagement, and posts with eye-catching images consistently outperform text-only updates. But image optimization goes beyond just looking pretty:

• Professional Polish: Correct dimensions ensure your visuals look sharp, intentional, and high-quality on both desktop monitors and mobile screens.
• No Awkward Cropping: Using the right aspect ratio prevents important text, logos, or faces from getting cut off.
• Maximized Screen Real Estate: Taller images take up more vertical space in the mobile feed, capturing more of your audience’s attention.

Deep Dive: Choosing the Right Format for Your Content

1. The Standard Link / Photo Post (Landscape)

• Dimensions: 1200 x 627 pixels
• Best for: Sharing blog post previews, external links, or wide landscape photography.
• Pro Tip: When sharing a link, LinkedIn will automatically pull the open-graph image from your website. Ensure your website images match this 1.91:1 ratio so they don’t appear warped in the feed.

2. The Feed Stopper (Vertical & Square)

• Dimensions: 1080 x 1350 px (Vertical) or 1080 x 1080 px (Square)
• Best for: Infographics, quotes, portfolio work, and promotional graphics.
• Pro Tip: Go vertical. While square images (1:1) are safe and clean, vertical images (4:5) take up significantly more physical space on mobile devices as users scroll through their feeds. More screen time equals higher engagement rates.

3. Document / Carousel Posts

• Dimensions: 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait) saved as a PDF.
• Best for: Educational slide decks, step-by-step guides, and thought-leadership breakdowns.
• Pro Tip: Keep text large, readable, and well-padded away from the edges. LinkedIn adds navigational arrows and UI overlays at the bottom of document posts, so keep critical information clear of the lower 15% of your slides.

Best Practices for Flawless LinkedIn Visuals

1. Mind the Mobile View: Over 60% of LinkedIn traffic happens on mobile devices. Always preview your graphics on a smartphone to ensure the text is legible at a smaller scale.
2. Stick to Approved File Formats: Upload your graphics as PNG or JPEG files. For animations or short loops, keep GIFs under 5 MB.
3. Keep Branding Consistent: Use a consistent color palette, typography hierarchy, and logo placement across your visual assets to make your brand instantly recognizable in a crowded feed.
4. Don’t Overcrowd Text: Let your imagery breathe. If your graphic is a wall of tiny text, busy professionals will simply scroll past it. Save the deep analysis for the post caption.

Wrap-Up

Mastering LinkedIn image dimensions doesn’t just make your profile look clean—it signals that you value quality and attention to detail. The next time you sit down to schedule your content, reference these dimensions, design with mobile users in mind, and watch your engagement climb!
