The Ultimate Guide to LinkedIn Post Image Sizes: Stop Getting Cropped Out

You spend hours crafting the perfect LinkedIn post. The hook is sharp, the insights are profound, and the call to action is airtight. You attach a striking graphic, hit “Post,” and check back later—only to find your masterpiece awkwardly cropped, blurry, or missing its focal point entirely.

Nothing kills professional momentum faster than a poorly formatted visual. Because LinkedIn is increasingly a mobile-first platform, understanding the exact pixel dimensions and aspect ratios for your images isn’t just a nice-to-have design detail—it’s a direct lever for driving engagement.

The Core LinkedIn Post Image Sizes at a Glance

Before diving into the specifics, here is the quick-reference cheat sheet for standard LinkedIn feed posts:

| Post Format | Recommended Dimensions (Pixels) | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square | $1080 times 1080$ | $1:1$ | The safe, universal default for infographics, quote cards, and cross-platform sharing. |
| Portrait / Vertical | $1080 times 1350$ | $4:5$ | Maximizing mobile screen real estate to capture attention and stop the scroll. |
| Landscape / Link Preview | $1200 times 627$ | $1.91:1$ | Traditional wide posts and automatic Open Graph link previews. |

Deep Dive: Choosing the Right Format for Your Goals

1. The Square Post ($1080 times 1080$ px) — The Reliable All-Rounder

If you are pressed for time or repurposing content from other platforms like Instagram, the square format is your best friend.

• Why it works: It renders predictably and cleanly across both desktop monitors and mobile screens without unexpected cropping.
• When to use it: Perfect for single-image announcements, high-level data charts, and multi-slide carousel documents (PDFs).

2. The Portrait Post ($1080 times 1350$ px) — The Engagement Powerhouse

With over half of all social media traffic happening on mobile devices, portrait orientation is a secret weapon for modern creators.

• Why it works: A $4:5$ aspect ratio stretches vertically down a smartphone screen, pushing competing posts out of view and forcing the reader to engage with your content longer.
• When to use it: Deep-dive infographics, step-by-step visual guides, and text-heavy summaries where readability is paramount.
• Pro Tip: While LinkedIn allows taller images (up to a $9:16$ ratio), it auto-crops them in the feed to $4:5$. Designing directly to $1080 times 1350$ ensures you retain total control over your composition.

3. The Landscape Post ($1200 times 627$ px) — The Link Preview Standard

Landscape images are wider than they are tall, mimicking traditional desktop displays.

• Why it works: It matches LinkedIn’s native link-sharing container. If you share an external article or blog post, this is the format LinkedIn pulls for the preview card.
• When to use it: Sharing outside URLs, media coverage, or corporate press releases. If you are uploading a standalone graphic just to text a point, landscape is usually outperformed by square or portrait formats because it leaves too much empty space on mobile screens.

Essential Technical Specs to Keep in Mind

Getting the dimensions right is half the battle; the rest comes down to meeting LinkedIn’s technical parameters to avoid auto-compression errors:

• File Size Limit: Keep your images under 5 MB. Anything larger risks failing to upload or causing stuttering load times.
• File Formats: Stick to JPEG/JPG for photographic images and complex color gradients (smaller file size) or PNG for clean graphics, text-heavy cards, or screenshots. WebP is also supported.
• Resolution: Always design at a high resolution (at least 1200 pixels wide for landscape or matching the exact dimension targets above) to ensure crisp rendering on high-density Retina displays.

Beyond the Feed: Profile and Banner Dimensions

Your post images grab attention, but your personal or company profile acts as your landing page. Make sure these foundational assets are properly sized to maintain authority:

• Personal Profile Picture: $400 times 400$ pixels minimum ($1:1$ ratio; keep your face centered since LinkedIn crops this into a circle).
• Personal Background Banner: $1584 times 396$ pixels ($4:1$ ratio). Watch out: Your profile picture overlaps the bottom-left corner on desktop, so keep important text and logos shifted toward the right side.
• Company Page Logo: $300 times 300$ pixels.
• Company Banner: $1128 times 191$ pixels.

Summary Checklist for Your Next Post

Before you hit publish on your next piece of content, run it through this quick checklist:

1. Match the layout to the medium: Use $1080 times 1350$ for mobile-heavy reach or $1080 times 1080$ for safe consistency.
2. Double-check text margins: Keep crucial text and elements away from the absolute outer edges so they don’t get clipped.
3. Verify the file format: Export as a clean PNG for graphics or JPG for photos, keeping the total size well under 5 MB.

By treating image dimensions as an intentional part of your strategy, you’ll ensure your content always looks sharp, professional, and built to convert.
