LinkedIn Post Image Size: Complete Guide

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

When you are scrolling through LinkedIn, what catches your eye first? Usually, it is not the wall of text—it is the visual. Whether it is a striking infographic, a team photo, or a carousel of insights, high-quality images can make or break your reach on the platform.

However, nothing kills a professional vibe faster than a stretched-out graphic, a cropped-off headshot, or a blurry, pixelated banner. LinkedIn’s image algorithms are notoriously picky, and uploading the wrong dimensions often results in awkward auto-cropping.

This complete guide covers everything you need to know about LinkedIn post image sizes, best practices, and insider tips to ensure your content always looks pristine.

Why LinkedIn Image Sizes Matter

LinkedIn’s feed is designed to reward clean, native content. If your image dimensions match what the platform expects:

• Your visuals stay intact: You avoid the dreaded automatic cropping that cuts off headlines, logos, or faces.
• Engagement increases: Crisp, well-formatted images signal professionalism and encourage users to click, comment, and share.
• Algorithm favorability: Clean rendering keeps users on your post longer, signaling to LinkedIn’s algorithm that your content is worth promoting.

Standard LinkedIn Post Image Sizes (At a Glance)

Depending on what kind of update you are publishing, you will want to target specific pixel dimensions and aspect ratios.

| Post Type | Ideal Dimensions (Pixels) | Aspect Ratio | Best Format |
| :— | :— | :— | :— |
| Standard Feed Post (Single Image) | 1200 x 627 px | 1.91:1 | PNG, JPEG |
| Vertical Feed Post (Tall) | 1080 x 1350 px | 4:5 | PNG, JPEG |
| Square Post | 1080 x 1080 px | 1:1 | PNG, JPEG |
| Link Preview Image | 1200 x 627 px | 1.91:1 | PNG, JPEG |
| Document/Carousel Post (per slide) | 1080 x 1080 px or 1080 x 1350 px | 1:1 or 4:5 | PDF |

Deep Dive: Choosing the Right Format for Your Post

1. The Standard Landscape Post (1200 x 627 px)

This is the classic rectangle format that automatically appears when you share a link with a preview image.

• When to use: Sharing blog posts, news articles, or website updates.
• Tip: If you are uploading an image manually rather than relying on a link preview, aim for this 1.91:1 ratio to ensure it fits the standard desktop feed width seamlessly.

2. The Square Post (1080 x 1080 px)

Symmetrical and balanced, the square format is a safe bet that looks great on both desktop and mobile feeds.

• When to use: Product announcements, quotes, event reminders, or simple infographics.
• Tip: Because mobile screens take up most of the vertical space, a square post commands more real estate in the mobile feed than a landscape post.

3. The Vertical Post (1080 x 1350 px) — The Growth Hack

If you want to maximize screen real estate, the 4:5 vertical ratio is your best friend.

• When to use: Deep-dive infographics, photography, or high-value visual takeaways.
• Tip: Mobile users make up the vast majority of LinkedIn traffic. A vertical image stretches down the screen, forcing users to pause their scroll and spend more time looking at your content.

4. Document / Carousel Posts (PDF Format)

LinkedIn carousels (created by uploading a multi-page PDF document) remain one of the highest-performing content formats for thought leadership.

• Ideal Dimensions: 1080 x 1080 px (Square) or 1080 x 1350 px (Vertical).
• Tip: Keep your typography large and readable (at least 24pt–30pt font), and make sure the file is saved cleanly as a high-resolution PDF before uploading.

Profile and Company Page Banner Sizes

It is not just about individual posts—your overall profile ecosystem matters too. Make sure your branding is consistent with these dimensions:

• Personal Profile Picture: 400 x 400 px (minimum)
• Personal Background Banner: 1584 x 396 px
• Company Page Logo: 300 x 300 px
• Company Page Banner (Hero Image): 1128 x 191 px

Pro Tips for Flawless LinkedIn Visuals

💡 Quick Rule of Thumb: Always design your graphics with mobile users in mind. Over 60% of LinkedIn traffic comes from smartphones, where vertical space is premium.

1. Keep Important Elements Centered: Avoid placing crucial text or faces right near the extreme edges of your canvas, just in case a mobile screen crops a few pixels.
2. Mind the File Size: LinkedIn accepts images up to 5MB (and sometimes larger for documents), but keeping your files optimized (ideally under 1-2MB) ensures faster loading times for your audience.
3. Stick to PNG or JPEG: Use PNG for sharp text and graphics with flat colors, and JPEG for rich photographs or complex imagery.
4. Check Contrast: Professional networks are often browsed in both light and dark mode. Ensure your text colors have high contrast against the background so they remain legible anywhere.

By utilizing the right dimensions for your LinkedIn images, you ensure your personal brand or business always looks polished, professional, and ready to engage.
