The Ultimate Guide to LinkedIn Post Image Sizes: Master Your Visual Branding in 2026

First impressions matter—especially in a professional feed crowded with updates, articles, and thought-leadership pieces. When scrolling through LinkedIn, a crisp, perfectly proportioned image can mean the difference between a user stopping in their tracks or casually swiping past your post.

Yet, nothing dilutes professional credibility quite like a pixelated, awkwardly cropped, or awkwardly stretched graphic. Because LinkedIn dynamically renders images across desktops, tablets, and smartphones, knowing the exact dimensions and aspect ratios required is essential for a polished, high-performing presence.

Whether you’re managing a personal profile, a company page, or running targeted ad campaigns, here is your definitive guide to LinkedIn post image sizes for 2026.

Why LinkedIn Image Sizes Matter

Before diving into the numbers, it helps to understand why precision counts. LinkedIn’s layout is optimized for specific dimensions to ensure fast loading times and a clean visual hierarchy.

• Preventing Awkward Crops: If your image dimensions fall outside the platform’s preferred aspect ratios, LinkedIn will automatically crop them, often cutting off vital text, logos, or faces.
• Maximizing Engagement: Visual posts consistently outperform text-only updates. High-resolution images that display in full fidelity encourage more clicks, comments, and shares.
• Reinforcing Brand Authority: Clean, professionally formatted graphics signal attention to detail—a critical trait in any B2B or professional networking environment.

Standard LinkedIn Post Image Sizes

Depending on the format of your post, the ideal dimensions vary. Here are the core specifications you need to bookmark:

1. Standard Feed Image (Single Image Post)

When you share a single photo or graphic directly to your feed, it appears as a rectangular card.

• Recommended Dimensions: 1200 x 628 pixels (or 1200 x 1200 pixels for a square layout)
• Aspect Ratio: 1.91:1 (landscape) or 1:1 (square)
• Best For: Infographics, event announcements, quote cards, and photography.

2. Square Image Posts

Square images have surged in popularity because they take up more vertical real estate on mobile feeds than landscape images, giving your content a higher chance of capturing attention.

• Recommended Dimensions: 1200 x 1200 pixels
• Aspect Ratio: 1:1
• Best For: Product spotlights, close-up shots, and bold, minimalist typography.

3. Vertical (Portrait) Posts

If you want to maximize screen space on mobile devices, portrait images are your best bet. They push surrounding text further down, forcing the user to engage with your graphic.

• Recommended Dimensions: 1080 x 1350 pixels (or 1080 x 1920 pixels for stories-style formats, though traditional feeds prefer 4:5)
• Aspect Ratio: 4:5
• Best For: Step-by-step guides, tall infographics, and portrait photography.

4. Link Preview Images

When you paste a URL into a LinkedIn post, LinkedIn automatically pulls an Open Graph image from that webpage.

• Recommended Dimensions: 1200 x 627 pixels
• Aspect Ratio: 1.91:1
• Best For: Blog posts, whitepapers, podcast episodes, and external landing pages.
• Pro Tip: Always double-check how your link preview renders using LinkedIn’s Post Inspector before hitting publish to ensure your custom thumbnail isn’t cut off.

Document Posts (Carousels)

LinkedIn Document posts—often referred to as carousels or PDFs—are one of the most effective organic reach tactics on the platform. Users can swipe through multiple pages natively in their feed.

• Recommended Dimensions: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Portrait)
• File Format: PDF
• Best For: Deep-dive breakdowns, step-by-step frameworks, slide decks, and data-heavy summaries.
• Pro Tip: Design your PDFs in tools like Canva or Figma, ensuring a high resolution so text remains crisp when users zoom in.

Profile and Background Images

Don’t forget your digital storefront! Your profile and banner images frame every single post you make.

• Profile Picture: 400 x 400 pixels (minimum) up to 7680 x 4320 pixels. Keep your face centered, as LinkedIn crops profile pictures into a circle.
• Personal Background Banner: 1584 x 396 pixels (4:1 aspect ratio). Keep important branding or text on the right side on desktop, as your circular profile picture overlays the bottom-left corner.
• Company Page Banner: 1128 x 191 pixels.

Best Practices for High-Performing LinkedIn Visuals

1. Keep Text Minimal: While text-heavy graphics can work in document carousels, single-image posts should rely on powerful visuals with concise, punchy headlines. If text is too small, it becomes illegible on mobile devices.
2. Prioritize Contrast: Use high-contrast color palettes that pop against LinkedIn’s stark white and grey interface (and look equally sharp in Dark Mode).
3. Save in the Right Format: Export your designs as PNG for graphics containing sharp text and logos, and JPEG for photographs to maintain optimal file sizes without sacrificing quality.
4. Mind the Safe Zones: Avoid placing essential information, logos, or text right along the extreme edges of your image, as minor UI overlays or automated rounding can clip them.

By adhering to these dimensions and best practices, you’ll ensure your visual content always looks intentional, professional, and optimized for maximum engagement.
