The Ultimate Guide to LinkedIn Post Image Sizes in 2026

When scrolling through LinkedIn, what makes you stop? For most professionals, it isn’t a wall of dense text—it’s a striking, crystal-clear visual. Images capture attention, break up the monotony of the feed, and significantly boost engagement rates.

However, there is nothing quite as frustrating as crafting a brilliant graphic, uploading it to LinkedIn, and watching the platform aggressively crop your masterpiece, cut off your headline, or turn a sharp photo into a blurry pixelated mess.

To ensure your visual content always looks professional, intentional, and high-impact, you need to use the right dimensions. Here is your complete guide to LinkedIn post image sizes for 2026.

Why LinkedIn Image Sizes Matter

LinkedIn’s algorithm favors posts that drive meaningful interactions—comments, shares, and dwell time. Visuals play a massive role in increasing dwell time because people pause to look at them.

If your image is formatted incorrectly:

• Awkward Cropping: Key text or faces might be cut off in the feed preview.
• Loss of Quality: Stretching a small image causes pixelation, which diminishes your brand credibility.
• Lower Engagement: A poorly formatted visual looks amateurish and encourages users to scroll right past.

Standard LinkedIn Post Image Sizes

Depending on the type of post you are sharing, the optimal dimensions vary. Here are the precise specifications you need to hit:

1. Standard Feed Image / Photo Post (Single Image)

Whether you are sharing a photo from a recent conference, a branded graphic, or an infographic, single-image posts are the backbone of LinkedIn visuals.

• Recommended Aspect Ratio: 1:1 (Square) or 4:5 (Vertical)
• Optimal Dimensions (Square): 1080 x 1080 pixels
• Optimal Dimensions (Vertical): 1080 x 1350 pixels
• Pro Tip: Vertical images (4:5) take up more vertical real estate on mobile screens, giving you a higher chance of stopping the user’s scroll.

2. Link Preview Images (Open Graph Images)

When you share a blog post, a news article, or an external website link, LinkedIn automatically generates a preview card using the page’s Open Graph image tag.

• Recommended Aspect Ratio: 1.91:1
• Optimal Dimensions: 1200 x 627 pixels
• Pro Tip: Always double-check how your link previews render before hitting publish. If the image looks zoomed in or cut off, update the featured image on your website.

3. Carousel Posts (Document Uploads)

Carousels (created by uploading a multi-page PDF document as a post) are currently one of the highest-performing content formats on LinkedIn for education and storytelling.

• Recommended Aspect Ratio: 1:1 (Square) or 4:5 (Vertical)
• Optimal Dimensions (Square): 1080 x 1080 pixels
• Optimal Dimensions (Vertical): 1080 x 1350 pixels
• Pro Tip: Keep your text legible with a font size of at least 24pt, and ensure important elements have plenty of padding away from the edges so they aren’t obscured by LinkedIn’s UI elements.

Profile and Company Page Dimensions (Bonus Guide)

Your post images are only part of the equation. To maintain a cohesive personal brand or corporate identity, make sure your profile assets are also correctly sized:

• Personal Profile Picture: 400 x 400 pixels (minimum), though higher resolutions like 800 x 800 work well as long as it stays under the file size limit.
• Personal Background Banner: 1584 x 396 pixels.
• Company Page Logo: 300 x 300 pixels.
• Company Page Cover/Hero Image: 1128 x 191 pixels.

Best Practices for Stunning LinkedIn Visuals

Knowing the numbers is only half the battle. Follow these best practices to maximize the impact of your images:

1. Mind the Safe Zones: Keep crucial text and logos centered. Avoid placing important details right on the outer edges where mobile screens or platform UI might clip them.
2. Watch Your File Formats: Stick to PNG for graphics with sharp lines and text, and JPEG for photographs. LinkedIn also supports GIF animations, but use them sparingly so they don’t become distracting.
3. Keep Text Accessible: Do not overload your images with text. LinkedIn is a professional network, but users consume content quickly, especially on mobile devices. Let your caption do the heavy lifting while the image hooks their attention.
4. Optimize for Mobile First: Over 70% of LinkedIn traffic originates from mobile devices. Always preview your post on a phone before calling it final to ensure text remains crisp and readable on smaller screens.

By sticking to these dimensions and design principles, you’ll ensure your content always puts its best foot forward, driving higher engagement and strengthening your professional presence on LinkedIn.
