LinkedIn Post Image Size: Every Dimension You Need in 2026

LinkedIn crops, compresses, and rescales images aggressively. Post the wrong size and your carefully designed visual turns into a blurry, awkwardly cropped mess in the feed. The fix is straightforward: use the exact dimensions LinkedIn expects.

Here is every LinkedIn post image size you need, followed by detailed guidance for each format.

Single Image Posts

Single image posts are the bread and butter of LinkedIn content. You have three aspect ratio options, and which one you pick depends on your goal.

Landscape (1200 × 628 px)

The classic LinkedIn image format. A 1.91:1 ratio that fills the feed width on both desktop and mobile. Best for:

• Blog post promotions with a featured image
• Data visualizations and charts
• Quote graphics with a wide layout
• Event announcements

Landscape images display consistently across devices, which makes them the safest default choice.

Square (1200 × 1200 px)

Square images take up more vertical space in the feed, which means more screen real estate and higher stopping power. The 1:1 ratio works well for:

• Infographics
• Product screenshots
• Team photos
• Single-stat callouts

On mobile, square images dominate the viewport. If your goal is to stop the scroll, square beats landscape.

Portrait (1080 × 1350 px)

Portrait images at 4:5 claim the most feed real estate of any single-image format. LinkedIn displays them tall on mobile, pushing other content below the fold. Use portrait for:

• Step-by-step visuals
• Tall infographics
• Before/after comparisons

One caveat: LinkedIn may crop portrait images in the feed on desktop, showing a "click to expand" overlay. Test your specific image to confirm the crop does not cut off key information.

Why 1200 px Wide?

LinkedIn recommends a minimum width of 552 px but displays images at up to 1200 px on high-DPI screens. Uploading at 1200 px wide ensures sharpness on retina displays without unnecessary file bloat. Go below 1200 px and your image looks soft on modern laptops and phones.

Carousel Posts (1080 × 1080 px)

LinkedIn carousels — officially called "document posts" — are one of the highest-engagement formats on the platform. Upload a PDF and LinkedIn converts each page into a swipeable slide.

Optimal specs:

• Dimensions: 1080 × 1080 px per slide (1:1 ratio)
• File format: PDF (or upload multiple images)
• Max slides: 300 pages (though 8–12 is the sweet spot for engagement)
• Max file size: 100 MB for PDFs

Design each slide at 1080 × 1080 px in your design tool, export as a single PDF, and upload. Text should be at least 24 px to remain legible on mobile screens.

Square carousels outperform landscape carousels because they occupy more vertical feed space on mobile, where most LinkedIn browsing happens.

Article Cover Images (1200 × 644 px)

When you publish a LinkedIn article (the long-form publishing feature, not a regular post), the cover image displays at the top. LinkedIn recommends 1200 × 644 px at a 1.86:1 ratio.

Keep critical content — text, logos, faces — centered and away from the edges. LinkedIn crops article covers differently depending on where they appear: in the article itself, in the feed preview, and in search results.

Document and PDF Posts (1080 × 1080 px)

Document posts and carousels share the same format. Upload a PDF or a PowerPoint file and LinkedIn renders each page as a slide. The key difference is intent: document posts often contain reports, whitepapers, or multi-page guides rather than swipeable visual carousels.

Specs are identical to carousels:

• 1080 × 1080 px per page for square format
• 1080 × 1920 px if you prefer portrait slides (9:16)
• PDF, PPT, PPTX, or DOC formats accepted
• 100 MB maximum file size

If your document contains detailed text, consider portrait (1080 × 1920 px) slides. The taller format gives you more vertical space for paragraphs and data tables, and the content still renders well on mobile.

Video Thumbnails (1200 × 628 px)

When you upload native video to LinkedIn, you can set a custom thumbnail. The thumbnail displays in the feed before the viewer hits play.

• Recommended size: 1200 × 628 px
• Aspect ratio: 1.91:1 (matching landscape image posts)
• Format: JPG or PNG

A strong thumbnail dramatically increases play rates. Use a frame with a clear focal point, readable text overlay, and high contrast. Avoid cluttered screenshots — they look like noise at thumbnail scale.

Desktop vs. Mobile Feed Display

LinkedIn renders the same image differently on desktop and mobile. Understanding the differences prevents unpleasant surprises.

The takeaway: Design for mobile first. Over 60% of LinkedIn sessions happen on phones. If your text is readable on a 375 px wide screen, it works everywhere. If it only looks good on a 1440 px monitor, you have lost the majority of your audience.

File Format and Compression

LinkedIn recompresses every image you upload. You cannot prevent this, but you can minimize the quality loss:

• Upload PNG for graphics with text, logos, or flat colors. LinkedIn's JPEG compression smears sharp edges and text. PNG preserves them better through the recompression pipeline.
• Upload JPG for photographs. Photos compress efficiently as JPEG with minimal visible loss.
• Stay under 10 MB. LinkedIn accepts up to 10 MB per image, but files over 5 MB trigger more aggressive compression. Aim for 1–3 MB for the best quality-to-compression ratio.

If your LinkedIn images are coming out blurry, the file is likely too large and triggering heavy recompression, or too small and being upscaled. For the right balance, compress your images before uploading — keeping files in the 1–3 MB range gives LinkedIn less reason to degrade quality.

Frequently Asked Questions

What is the best LinkedIn post image size?

1200 × 1200 px (square) for maximum feed visibility, or 1200 × 628 px (landscape) for the safest cross-device compatibility. Square takes up more screen space on mobile, while landscape displays consistently on both desktop and mobile without cropping.

Does LinkedIn crop images?

Yes. LinkedIn crops images that do not match its expected aspect ratios. Portrait images taller than 4:5 get cropped in the feed with a "click to expand" prompt on desktop. Always place critical content — faces, text, logos — in the center of the image to survive cropping.

What size should a LinkedIn carousel be?

1080 × 1080 px per slide. Export all slides as a single PDF. Keep text at 24 px or larger for mobile legibility. LinkedIn supports up to 300 slides, but engagement peaks at 8–12 slides.

What format should I use for LinkedIn images — JPG or PNG?

Use PNG for graphics with text, logos, or flat colors. Use JPG for photographs. LinkedIn recompresses everything, and PNG handles that recompression better for sharp-edged graphics. Check our guide on social media image sizes for format recommendations across all platforms.

Why do my LinkedIn images look blurry?

Three common causes: uploading images below 1200 px wide (LinkedIn upscales them poorly), uploading files over 5 MB (triggering aggressive recompression), or using JPG for text-heavy graphics (compression smears text edges). Resize to the correct dimensions and compress to 1–3 MB before uploading.

What is the LinkedIn article cover image size?

1200 × 644 px at a 1.86:1 aspect ratio. Keep important elements centered — LinkedIn crops the cover differently in the feed preview, article page, and search results.

Are LinkedIn image sizes different for company pages?

No. Company page posts use the same image dimensions as personal posts. The feed rendering is identical. The only difference is the LinkedIn banner size, which varies between personal profiles and company pages.
