For a LinkedIn article header to look sharp, you need to get the size right. The standard is 1920 x 1080 pixels. It's a simple rule that stops your main image from looking blurry or awkwardly cropped.

For images you place inside the article itself, keep their width between 700 and 800 pixels. Anything larger is unnecessary and can slow down page loading; anything smaller might look pixelated.

The Definitive LinkedIn Image Size Cheat Sheet

Getting your visuals right on LinkedIn means knowing the specific dimensions for each type of placement. This isn't just about making things look good—it's about making sure your message isn't cut off or distorted.

Here is a quick reference table with the most up-to-date specifications for 2026. Keep this handy so you never have to guess again.

LinkedIn Image Size Specifications (2026)

Image Placement	Recommended Dimensions (Pixels)	Aspect Ratio	Max File Size

Profile Banner	1584 x 396	4:1	8 MB
Company Logo	300 x 300	1:1	4 MB
Company Cover Photo	1128 x 191	5.91:1	4 MB
Post Image (Square)	1200 x 1200	1:1	5 MB
Post Image (Portrait)	1080 x 1350	4:5	5 MB
Link Preview Image	1200 x 627	1.91:1	5 MB
Article Header Image	1920 x 1080	16:9	10 MB

These numbers are your foundation for a professional visual presence on the platform. Sticking to them ensures your profile and content are presented exactly as you intended.

Quick Reference for Key Image Sizes

Sometimes a visual guide is the fastest way to understand the differences between placements. This graphic breaks down the most common sizes you'll be working with.

Notice how different the aspect ratios are. A 16:9 header, a 1:1 feed post, and a 1.91:1 link preview all require their own custom-sized graphic. Reusing the same image without resizing is a common mistake that immediately makes a brand look unprofessional.

Using the right image sizes is a small detail that signals you care about the quality of your work. It's a non-negotiable part of a solid content strategy.

And if you’re trying to build a more organized approach to publishing, great visuals are only half the battle.

Pairing optimized images with a consistent schedule is how you start to see real results.

Designing the Perfect LinkedIn Article Header Image

The best size for a LinkedIn article header image is 1920 x 1080 pixels. This gives you the standard 16:9 aspect ratio that displays perfectly on desktop.

When you use the right dimensions, LinkedIn won’t stretch or squash your image. It’s a small detail, but getting it right makes your work look far more professional and polished.

How LinkedIn Crops Your Header Image

Even though you upload a 1920 x 1080 image, it won’t always appear that way. The full 16:9 version is usually only visible at the top of the article itself.

In other places, like the main LinkedIn feed or your profile's activity section, the image gets cropped. LinkedIn cuts off the top and bottom, creating a wider, more panoramic preview.

Key Takeaway: Don't put anything important near the top or bottom edges of your image. Text, logos, or faces in these areas will get cut off in previews.

Using a Visual Safe Zone

The safest approach is to keep all your important visual information in the center. Think of your 1920 x 1080 canvas as having a "safe zone" running through the middle.

• Center your logo: Place any branding squarely in the horizontal middle of the image.
• Keep text centered: Article titles or text overlays belong in this central band, too.
• Check the mobile view: Cropping on phones can be even more aggressive, so the center is the only part you can count on being seen.

By keeping your key elements centered, you can be sure they’ll show up, whether someone sees the full header or just a cropped preview in their feed. This kind of consistency is a huge part of building a recognizable brand. You can discover more strategies for this in our detailed guide on building a personal brand on LinkedIn.

Images Inside Your LinkedIn Article

Your article's header gets the first click, but the images inside keep people reading. They break up walls of text and make complex points easier to grasp.

The goal is to make sure your images fit cleanly within the article's main column. The best practice is to size any in-article image to a maximum width of 700 to 800 pixels. This keeps them sharp without forcing readers to scroll sideways or wait for a slow-loading page.

In-Article Image Aspect Ratios

Unlike the rigid 16:9 header image, you have a lot more freedom with the aspect ratios for images inside the article body. Most standard ratios look great.

• Standard Photos (4:3 or 3:2): These are perfect for most screenshots, photos, or simple graphics. They illustrate your point without taking over the entire screen.
• Tall Graphics (Infographics): If you have a detailed chart or a long infographic, you can use a taller image. LinkedIn handles it well, letting readers scroll through the graphic within your article.

This flexibility lets you get creative with your layout. For example, if you want to group several images into a single, swipeable format, that's a great way to stand out in the feed. A LinkedIn carousel builder can help you design that kind of engaging, multi-slide content.

Pro Tip: Always compress your images before you upload them. A tool like TinyPNG can slash your file size without any obvious drop in quality, which means your article will load faster for everyone.

Alt-Text for Accessibility and SEO

Never skip the alt-text on your images. It’s essential for a couple of reasons.

First, it makes your article accessible to people who use screen readers. Second, it tells search engines what your image is about, which helps with your article's SEO. Just write a simple, clear description of what the image shows.

Nailing the 1200x627 Link Preview Image

When someone shares a link to your content on LinkedIn, the platform creates a clickable preview for you. That preview is your first, and often only, chance to get someone’s attention in a crowded feed. To control that first impression, you need an optimized 1200 x 627 pixel link preview image.

This specific size locks in a 1.91:1 aspect ratio, which has become the standard for link previews across most social platforms. If you don't have an image ready for this, LinkedIn might grab your header image or another random graphic from the page. This almost always leads to weird cropping and a sloppy look. For anyone trying to get more clicks, this is a detail you can't afford to get wrong.

How to Control Your Link Preview Image

You can tell LinkedIn exactly which image to use with Open Graph (OG) meta tags in your website’s HTML. Specifically, the og:image tag, placed in the <head> section of your page, points social platforms to the right image.

All you have to do is set this tag to the URL of your perfectly sized 1200 x 627 pixel image. This ensures a sharp, clean, and correctly framed preview every single time someone shares your link.

The Bottom Line: If you don't set an og:image, you're letting LinkedIn decide how your brand looks. That’s a gamble that can make your work seem low-quality before anyone even clicks.

Using this specific landscape og:image can genuinely improve your content's reach. The latest guides confirm these dimensions make visuals display correctly on both desktop and mobile, with no distortion. We’ve also seen for years that posts with optimized images get much higher engagement than those with bad crops or no image at all.

Quick Tips for a Better og:image

To make a preview image that actually works, just follow these simple rules:

• Show the Title: Put the article headline on the image in a big, easy-to-read font.
• Add Your Brand: Place your logo or website name on the image, but don't let it overpower the design.
• Use a Strong Visual: Pick a background image that’s relevant and grabs attention.
• Keep It Simple: Don't cram the image with too much text or other distracting elements.

Think of a good og:image as a small ad for your content. It draws people in, encourages clicks, and makes you look more professional.

Why 1080x1080 Square Images Still Dominate the Feed

Square images don't go inside your article, but they are one of the best ways to promote it. Think of a separate 1080 x 1080 pixel post as a dedicated ad for the piece you just wrote. This approach treats promotion as its own important step.

The 1:1 aspect ratio is designed to stop the scroll. Square images simply take up more screen space on a phone than landscape photos do, which makes them much harder to ignore as someone is browsing their feed.

This format is perfect for making graphics that you can share to hint at your article's value. You could pull out a strong quote, a key statistic, or just a branded graphic that points to your main idea. These act like small, effective billboards for your longer content.

The Mobile-First Advantage

The reason the square format is so popular comes down to mobile. Ever wonder why you see so many 1080 x 1080 pixel images from LinkedIn's top creators? The 2026 specs show that this 1:1 ratio gives you the most vertical space, boosting visibility by 25% over landscape images on a phone—which is where 60% of LinkedIn’s 1 billion users are.

This is one place where Maito’s editor helps, as it shows you exactly how your square image will look next to your post text and removes the guesswork. You can explore the latest LinkedIn size specifications to see why it’s become a professional standard.

More screen space means your image is harder to miss. It’s a simple way to get attention in a feed that moves incredibly fast.

How to Use Square Images Effectively

The strategy is direct. You create a compelling 1080 x 1080 visual and share it as a normal LinkedIn post. In the post text, you write a hook and add the link to your full article.

The winning combination: A scroll-stopping square image, a hook in the caption, and a clear link to your article. This approach is much more effective than just sharing a link by itself.

Getting the Technical Details Right

Getting the pixel dimensions right is only half the battle. If you ignore the technical specs of your image file, LinkedIn can still ruin its quality.

File Type, File Size, and Resolution

Your first choice is the file type. Use JPG for photos. It keeps file sizes small while maintaining good quality for complex images. For anything with sharp lines, crisp text, or a transparent background—like logos or diagrams—use PNG.

Next, watch your file size. LinkedIn has strict limits, like keeping shared post images under 5MB. If you upload a file that’s too large, the platform will compress it aggressively, and your image will end up looking blurry and pixelated. Always compress your images before you upload them.

Finally, you need to account for high-resolution screens. If you save an image at the exact recommended dimensions, it can look a little soft on modern "Retina" displays.

Here’s a simple trick to keep your images looking sharp on any device:

• Design your image at 2x the recommended pixel dimensions.
• Export it at the final, required size (1x).

This technique gives the final image more pixel data to work with, making it look much crisper.

While we're focused on screens here, a deeper dive into dots per inch (DPI) is useful for a full picture of image quality, especially if you ever need print-ready assets. You can learn more by understanding image resolution for print.

Common Questions About LinkedIn Image Sizes

Getting LinkedIn images right can still lead to a few common questions. Here are some quick answers to the problems that pop up most often.

What Happens If My Article Header Image Is the Wrong Size?

If your header image isn't the recommended 1920 x 1080 pixels, LinkedIn will crop it to fit. This almost always looks awkward and unprofessional.

A wider image gets the sides chopped off, and a taller one loses the top and bottom. Either way, you risk cutting off key parts of your message or branding.

Can I Use Animated GIFs in a LinkedIn Article?

No, you can't put animated GIFs inside a LinkedIn Article. The platform only supports static images like JPG and PNG.

A better approach is to create a standard LinkedIn post with your engaging GIF, then link back to your full article from that post's text.

How Do I Control the Thumbnail When Sharing My Article?

You control the share thumbnail with your website's Open Graph tags, specifically the og:image tag. If this tag is missing, LinkedIn just guesses, often grabbing a poorly cropped header or another random image from the page.

To make sure LinkedIn shows the right preview, you need to point the og:image tag to a 1200 x 627 pixel image URL in your article's HTML <head> section.

If you really want to master your image settings, it's worth reading a comprehensive image resolution guide.
