The Ultimate Guide to LinkedIn Post Image Sizes: Stop Your Visuals from Getting Cropped

We have all been there. You spend hours crafting the perfect LinkedIn update, design a slick accompanying graphic, hit “Post,” and… disaster. Your beautifully centered text is awkwardly sliced off, your logo is swallowed by a button, or your stunning photo is stretched into a blurry pixelated mess.

On a professional platform where first impressions dictate whether a reader stops scrolling or keeps moving, visual presentation matters. Because LinkedIn automatically compresses and crops images depending on whether your audience is viewing from a desktop or a smartphone, knowing the exact dimensions required for your content is a non-negotiable superpower for creators, marketers, and professionals alike.

This comprehensive guide breaks down everything you need to know about LinkedIn post image sizes, including standard feed dimensions, layout strategies, and file format tips to ensure your content always looks crisp and professional.

1. Single Image Post Sizes: The Feed Powerhouses

When you publish a standalone image post, LinkedIn gives you a few layout options. Choosing the right one depends entirely on how you want to capture screen real estate.

A. The Square Format (1:1 Ratio) — 1080 x 1080 pixels

• The Vibe: Clean, balanced, and versatile.
• Best Used For: Infographics, quote cards, product shots, and general branding.
• Why it works: Square is the ultimate “safe” format. It renders predictably across both desktop feeds and mobile screens without unexpected cropping shocks. If you are cross-posting content from Instagram, square images port over seamlessly.

B. The Portrait / Vertical Format (4:5 Ratio) — 1080 x 1350 pixels (or 1200 x 1500 pixels)

• The Vibe: Bold, modern, and mobile-optimized.
• Best Used For: Deep storytelling, detailed step-by-step breakdowns, and high-converting visual thought leadership.
• Why it works: Over half of all LinkedIn traffic originates on mobile devices. Because vertical images take up maximum vertical height on a smartphone screen, they command attention and keep eyes locked on your post longer. It is the favorite format among top LinkedIn creators for driving engagement.
• Pro Tip: Avoid pushing your aspect ratio past 4:5 (like a 9:16 story format); LinkedIn will automatically crop super-tall images down in the feed.

C. The Landscape Format (1.91:1 Ratio) — 1200 x 627 pixels

• The Vibe: Traditional, cinematic, and professional.
• Best Used For: Landscape photography, broad data visualizations, or when your accompanying text does most of the heavy lifting.
• Why it works: This is LinkedIn’s legacy image size. While it looks great on wide desktop monitors, it takes up minimal vertical space on mobile phones. Use this primarily when sharing link previews or wide-angle graphics where cropping would ruin the composition.

2. Multi-Image & Carousel (Document) Sizes

If you are publishing more than one image or uploading a document slide deck, the rules change slightly.

• Multi-Image Posts (2–9 photos): For a grid or photo gallery, stick to a 1080 x 1080 pixel square format. LinkedIn arranges multi-image posts dynamically, and square layouts prevent weird cropping anomalies across the grid.
• Carousels / Document Posts (PDFs): Document carousels are engagement goldmines on LinkedIn. Design your slides using either a 1080 x 1080 (Square) or 1080 x 1350 (Portrait) aspect ratio. Save your final design as a high-resolution PDF before uploading it as a document.

3. Profile & Banner Sizes: Setting the Stage

Your post images grab attention in the feed, but your profile and company page act as your digital storefront. Make sure they aren’t letting you down:

• Personal Profile Picture: 400 x 400 pixels (minimum) up to 800 x 800 pixels (recommended). Keep your face centered, occupying roughly 60% of the frame, as LinkedIn crops your square upload into a circular badge.
• Personal Background Banner: 1584 x 396 pixels (4:1 ratio). Crucial Warning: Mobile devices crop the outer edges of personal banners. Keep all vital text, logos, and focal points inside a centered 1200 x 300 pixel safe zone.
• Company Page Logo: 300 x 300 pixels (PNG format recommended for clean transparent or solid vector scaling).
• Company Cover Photo: 1128 x 191 pixels (roughly 6:1 ratio).

4. Technical Constraints: Formats and File Sizes

Getting the pixel dimensions right is only half the battle. To prevent LinkedIn’s automated compression engine from turning your graphic into a blurry mess, keep these technical guardrails in mind:

• Max File Size: Keep feed images under 5 MB (and profile assets under 8 MB).
• File Formats:
  • Use JPG / JPEG for standard photographs and complex color gradients (smaller file size).
  • Use PNG for graphics featuring sharp text, typography, logos, or solid color blocks to preserve clean edges.
  • WebP files are fully supported for feed posts and offer efficient compression.

Summary Cheat Sheet

| Asset Type | Recommended Dimensions | Aspect Ratio |
| :— | :— | :— |
| Square Post | 1080 x 1080 px | 1:1 |
| Vertical / Portrait Post | 1080 x 1350 px | 4:5 |
| Landscape Post / Link Preview | 1200 x 627 px | 1.91:1 |
| Profile Picture | 400 x 400 px (min) to 800 x 800 px | 1:1 |

By tailoring your image sizes to match how LinkedIn’s layout engine treats desktop and mobile feeds, you instantly elevate your personal brand or business page. Swap out those blurry, auto-cropped graphics for optimized assets, and watch your visual content work harder for your brand.
