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

Whether you are building your personal brand, promoting a B2B business, or sharing company culture, visuals are non-negotiable on LinkedIn. Posts with images generate significantly higher engagement, more comments, and wider reach than text-only updates.

However, there is nothing worse than spending hours crafting a brilliant graphic, only to upload it and watch LinkedIn violently crop out your headline, squeeze your charts, or leave annoying gray borders around your masterpiece.

To ensure your visuals always look sharp, professional, and purpose-built, here is the ultimate guide to LinkedIn post image sizes for every format.

Deep Dive: Choosing the Right Format for Your Goal

1. The Vertical Post ($1080 times 1350$ px) — The Scroll Stopper

If your primary goal is maximum visibility in the mobile feed, vertical images are your best friend.

• Why it works: Because the LinkedIn mobile app is vertical, a $4:5$ aspect ratio takes up significantly more physical screen estate than a standard landscape photo.
• Use it for: Infographics, data visualizations, and text-heavy summaries that demand user attention.

2. The Square Post ($1080 times 1080$ px) — The Versatile All-Rounder

When you aren’t sure whether your audience is viewing your content on a massive desktop monitor or a smartphone, the $1:1$ square format is the safest bet.

• Why it works: It renders cleanly and predictably across all devices without awkward auto-cropping.
• Use it for: Team photos, event highlights, customer testimonials, and inspirational quote cards.

3. Landscape & Link Previews ($1200 times 627$ px) — The Professional Standard

This horizontal ratio mirrors standard Open Graph (OG) image dimensions, making it ideal for sharing blog posts, external articles, or website landing pages.

• Pro-Tip: When sharing a link, LinkedIn automatically pulls the preview image from your website’s meta tags. Always ensure your blog post header images match or exceed $1200 times 627$ pixels so they don’t render as a tiny, pixelated thumbnail.

4. Document / Carousel Posts ($1080 times 1350$ px) — The Engagement Engine

LinkedIn carousels (uploaded as multi-page PDF documents) remain one of the highest-performing content formats on the platform.

• Design Rule: Keep your PDF slides formatted to a clean $1080 times 1350$ resolution. Ensure your typography is large and legible (at least 24pt to 32pt font sizes) so users can easily swipe through on mobile devices without pinching and zooming.

Technical Specifications & Best Practices

• Accepted File Formats: Stick to PNG or JPEG for standard images. Avoid GIFs for static posts, as LinkedIn converts them into looping video files, which can degrade quality.
• File Size Limits: LinkedIn allows images up to 5MB. If your editing software exports a file larger than that, run it through a compression tool like TinyPNG before uploading.
• Color Profile: Design your graphics in sRGB color space to ensure the colors look vibrant and accurate across both Apple Retina displays and standard PC monitors.
• The “Safe Zone” Rule: Always leave a small padding margin around the outer edges of your graphic. Keep critical text, logos, and focal points centered so they never risk getting clipped by UI elements like profile avatars or caption overlays.

Wrapping Up

Mastering LinkedIn image sizes isn’t just about avoiding ugly crops—it’s about respecting your audience’s visual experience. When your graphics look crisp, deliberate, and professional, you instantly signal authority, credibility, and polish before a user even reads your first sentence.
