Mastering LinkedIn Post Dimensions: The Ultimate Visual Guide for 2026

When scrolling through LinkedIn, what makes you stop? Is it a dense wall of text, or is it a striking, professionally formatted visual that immediately catches your eye?

In a professional network crowded with thoughts, updates, and articles, visuals are your greatest weapon for stopping the scroll. However, posting an image that is awkwardly cropped, blurry, or stretched instantly undermines your credibility. LinkedIn’s algorithms—and its discerning professional audience—favor clean, high-resolution, perfectly sized content.

Whether you are a B2B marketer, a job seeker building your personal brand, or a company page admin, this comprehensive guide covers everything you need to know about LinkedIn post dimensions to make your content look pristine.

Why LinkedIn Image Dimensions Matter

Before diving into the numbers, let’s look at why getting your image ratios right is critical:

1. First Impressions: Your content is a reflection of your brand. Cropped-out heads or blurry text boxes look amateurish.
2. Engagement Boost: Posts with images consistently outperform text-only posts in comments, shares, and overall reach.
3. Algorithm Preference: LinkedIn’s feed renders specific formats better. When your images fit the native containers seamlessly, users stay engaged longer, signaling quality to the algorithm.

LinkedIn Image Sizes Cheat Sheet (2026)

1. Standard Shared Image (Single Image Post)

When you share a photo or graphic directly into the feed, you want it to look sharp on both desktop and mobile.

• Recommended Size: 1200 x 628 pixels (Landscape) or 1080 x 1350 pixels (Vertical/Portrait)
• Aspect Ratio: 1.91:1 (Landscape) or 4:5 (Vertical)
• Pro Tip: While horizontal images have been the traditional standard, vertical images (4:5) take up more valuable vertical screen space on mobile devices, leading to significantly higher engagement rates.

2. Document Posts (Carousels / PDFs)

Document uploads (often referred to as carousels or swipe-throughs) are one of the most effective organic reach strategies on LinkedIn. When uploaded as a PDF, users can swipe through multiple pages.

• Recommended Size: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Portrait)
• Aspect Ratio: 1:1 or 4:5
• Pro Tip: Keep text large, readable, and well-padded within the margins so it doesn’t get cut off by LinkedIn’s native UI overlays (like the swipe arrows or profile headers).

3. Link Preview Images

When you paste a URL into a LinkedIn post, the platform automatically generates a link preview card with an image scraped from the website’s Open Graph tags.

• Recommended Size: 1200 x 628 pixels
• Aspect Ratio: 1.91:1
• Pro Tip: Always double-check how your link preview renders before hitting publish. If the image looks cropped or low-res, upload a custom image directly or ensure your website’s metadata is optimized.

4. Company Page & Personal Profile Banners

Your profile or company page banner is your digital storefront.

• Personal Profile Background: 1584 x 396 pixels (Aspect Ratio: 4:1)
• Company Page Banner: 1128 x 191 pixels (Aspect Ratio: ~6:1)
• Profile Picture (Personal/Company Logo): 400 x 400 pixels minimum (Aspect Ratio: 1:1, displayed as a circle).
• Pro Tip: On personal profiles, remember that your circular profile picture overlaps the bottom-left corner of your background banner. Keep critical text and logos on the right side of your personal banner!

Best Practices for LinkedIn Visuals

• File Formats: Stick to PNG for graphics with text and crisp lines, and JPEG or WebP for photographs. LinkedIn supports GIFs, but use them sparingly and only when they add genuine value.
• Keep Text Minimal: While carousels rely on text, single-image posts should let the graphic do the heavy lifting. Avoid dense paragraphs inside images, as they are unreadable on mobile screens.
• Prioritize Mobile: Over 60% of LinkedIn traffic comes from mobile devices. Always preview your designs on a phone screen before publishing.
• Maintain Brand Consistency: Use consistent color palettes, fonts, and logo placements so followers instantly recognize your content in their feed.
