LinkedIn Post Image Size Guide: Dimensions & Specs

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

Ever spent time crafting the perfect text for a LinkedIn post, only to upload an image that gets awkwardly cropped, blurry, or cut off at the edges? First impressions matter, especially on a professional network where visual quality signals credibility.

Whether you are building your personal brand, sharing company updates, or running a campaign, getting your dimensions right is the secret to making your content pop in the feed. This guide covers everything you need to know about LinkedIn image sizes, aspect ratios, and best practices.

Why LinkedIn Image Sizes Matter

LinkedIn is a professional space, and visuals act as a hook. High-resolution, correctly proportioned images:

• Grab attention: Feed algorithms favor clean, high-performing visual assets that don’t look distorted.
• Look professional: Blurry or awkwardly cropped photos can unintentionally make a brand look unpolished.
• Maximize screen real estate: Using the optimal dimensions ensures your entire message and focal point remain visible without requiring the user to click to expand.

Quick Reference: Standard LinkedIn Post Image Sizes

Here are the optimal dimensions for the most common types of LinkedIn image posts:

| Post Type | Ideal Dimensions (Pixels) | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Standard Post / Photo | $1200 times 627$ px | $1.91:1$ | Link previews, blog shares, landscape photos |
| Square Post | $1080 times 1080$ px | $1:1$ | Infographics, standard product shots, quotes |
| Vertical / Portrait Post | $1080 times 1350$ px | $4:5$ | Deep-dive graphics, tall portraits, mobile-first design |
| Carousel / Document | $1080 times 1080$ px or $1080 times 1350$ px | $1:1$ or $4:5$ | Multi-page PDF slides, step-by-step guides |

Breaking Down the Formats

1. Landscape / Standard Link Images ($1200 times 627$ px)

This is the traditional rectangle format commonly seen when sharing website links or standard landscape photography.

• Tip: If you are sharing a link, LinkedIn automatically pulls the open-graph image from your website. Ensure your website’s preview image matches this $1.91:1$ ratio so it doesn’t get awkwardly cropped.

2. Square Images ($1080 times 1080$ px)

Square images are versatile and look great on both desktop and mobile feeds. Because they take up more vertical space than landscape images, they naturally draw a bit more attention as users scroll.

• Tip: Perfect for minimalist graphics, quote cards, or headshots.

3. Vertical Images ($1080 times 1350$ px)

If you want to maximize mobile screen time, vertical formats are your best friend. Since the majority of LinkedIn browsing happens on mobile devices, a $4:5$ ratio takes up the most vertical feed space allowed for standard single images, pushing competing content further down the screen.

4. Carousels & Documents ($1080 times 1080$ px or $1080 times 1350$ px)

Instead of uploading a single photo, LinkedIn allows you to upload multi-page PDF documents that users can swipe through like a carousel.

• Tip: Design your slides in a tool like Canva using a square ($1080 times 1080$) or portrait ($1080 times 1350$) layout. Keep text large and readable, as users will be swiping through quickly.

Don’t Forget Profile & Banner Sizes!

While feed images are crucial for daily posting, your profile or company page layout sets the stage:

• Personal Profile Picture: $400 times 400$ px (minimum)
• Personal Background Banner: $1584 times 396$ px
• Company Page Logo: $300 times 300$ px
• Company Banner / Cover Image: $1128 times 191$ px

Pro-Tips for Flawless LinkedIn Visuals

1. Design for Mobile First: Over 60% of LinkedIn traffic comes from mobile devices. If text or important details are crammed into the extreme corners of an image, they might get covered by UI elements or user interface buttons.
2. Watch the File Size: LinkedIn supports JPEG, PNG, and GIF formats. Keep your file sizes reasonable (ideally under 5MB) to ensure fast loading times without sacrificing clarity.
3. Keep Text Minimal: Images overloaded with text can be hard to read, especially on smaller screens. Let your post caption do the heavy lifting, and use the image to complement or illustrate your core idea.

By sticking to these dimensions, your content will look sharp, professional, and ready to engage your network!
