LinkedIn Post Image Size Guide: Dimensions & Specs

The Ultimate Guide to LinkedIn Post Image Sizes in 2026

When you scroll through your LinkedIn feed, what catches your eye first? Usually, it is not the text—it is the visual. Whether it is a striking infographic, a carousel, or a candid photo of a team milestone, high-quality images drive engagement, comments, and shares.

However, there is nothing more frustrating than spending hours crafting a post, uploading an image, and discovering that LinkedIn has brutally cropped out your headline or turned your crisp graphic into a blurry pixelated mess.

To ensure your content always looks professional, here is the complete, up-to-date guide to LinkedIn post image sizes and dimensions.

Why LinkedIn Image Sizes Matter

LinkedIn’s algorithm favors dwell time—how long users stop to read or look at your post. If an image is cropped awkwardly or takes forever to load because it is too large, users will simply scroll past.

Using the exact recommended dimensions ensures:

• Zero Awkward Cropping: Your key messaging and focal points stay safely within the visible frame.
• Maximum Clarity: Your graphics remain sharp across both desktop and mobile devices.
• A Professional Polish: Clean formatting signals credibility and attention to detail.

Deep Dive: Choosing the Right Format for Your Goal

1. The Square Post (1080 x 1080 px)

The square format is the workhorse of social media. Because it takes up a healthy amount of vertical space on both desktop and mobile feeds without forcing the user to tap “see more,” it is ideal for quotes, promotional announcements, and bold statements.

2. The Vertical Post (1080 x 1350 px)

If your primary audience browses LinkedIn on their phones (which the vast majority do), vertical images are your secret weapon. A 4:5 aspect ratio dominates the mobile screen, forcing users to pause their scroll. Use this size for infographics, step-by-step guides, or portraits where composition matters.

3. Standard Landscape (1200 x 627 px)

This is the traditional size optimized for link shares. When you paste a URL into LinkedIn, it usually pulls an open-graph image at roughly this dimension. If you are uploading a standalone landscape photograph (like a conference stage or office space), stick close to this ratio so the edges don’t get cut off.

4. Document / Carousel Posts (PDF Uploads)

Carousels continue to be one of the highest-performing content formats on LinkedIn for organic reach. To create a carousel, you design your slides in a tool like Canva and export them as a PDF, which you then upload as a document.

• Pro Tip: Design your pages at 1080 x 1350 px (Vertical). This gives your readers a larger, more immersive viewing experience when they click through the slides.

Best Practices for LinkedIn Visuals

• Watch the Safe Zones: Keep crucial text and logos away from the absolute edges of your design. LinkedIn sometimes adds interface overlays or icons near the corners.
• Mind File Formats: Stick to PNG for graphics with text and sharp lines, and JPEG for photographs to keep file sizes manageable.
• Keep Text Readable: LinkedIn is often read in “Dark Mode” by many users. Ensure your color contrast is high enough that text is legible against both white and dark backgrounds.
• Don’t Overcrowd: A cluttered graphic lowers conversion and read rates. Let your visuals breathe with plenty of white space.

By matching your dimensions to how people actually consume content—especially on mobile—you will instantly elevate your brand presence and keep your audience engaged from the first second.
