Image Size for LinkedIn Posts: Ultimate Guide for Perfect Results

When you share a post on LinkedIn, you want it to look sharp. For the best results, stick to a size of 1200 x 627 pixels for any shared links or standard landscape images.

If you prefer a square look, which works great on mobile feeds, an aspect ratio of 1:1 is your best bet. A dimension of 1200 x 1200 pixels will keep your images looking crisp and consistent no matter where people see them.

A Quick Guide to LinkedIn Image Sizes

Getting your image dimensions right is one of those small details that makes a huge difference. When your images are sized incorrectly, LinkedIn can crop them awkwardly, make them look blurry, or compress them into a pixelated mess. This can really hurt the professional look you're going for.

Nailing the right specs means your visuals will always be clear, sharp, and render perfectly on both desktop and mobile. It's a simple step that signals you care about quality and helps your brand look its best. To make it easy, I've pulled together all the essential numbers you need.

Core LinkedIn Image Dimensions

Here are the three most common image sizes you'll be working with day-to-day:

• Profile Picture: 400 x 400 pixels
• Feed Post (Landscape): 1200 x 627 pixels
• Cover Photo: 1584 x 396 pixels

This infographic gives you a good visual comparison of these three key image types, so you can see how their shapes and purposes differ.

As you can see, there's a big difference between the wide, panoramic format of a cover photo and the much more compact, square-ish profile picture and feed post images.

To make things even easier, here’s a quick reference table with the most common image sizes all in one place.

Getting Your Images Right for the LinkedIn Feed

When you post on LinkedIn, the size and shape of your image can make or break its performance. How much space your post takes up on someone's screen, especially on a phone, is a huge deal. That's why square and portrait images almost always beat out the traditional landscape format.

Think about it: the more screen real estate you command, the more likely you are to stop someone mid-scroll. Choosing the right format is your first step to grabbing that attention.

Square vs. Portrait Images

Your two best bets for a high-impact visual in the feed are the 1:1 (square) and 4:5 (portrait) aspect ratios.

• Square Images (1:1 Aspect Ratio): The go-to size here is 1080 x 1080 pixels. This format is a workhorse. It looks clean and professional on every device, from a wide desktop monitor to a small smartphone screen, with zero risk of weird cropping. It’s a reliable, safe choice for just about any visual you want to share.

• Portrait Images (4:5 Aspect Ratio): For a taller image, use 1080 x 1350 pixels. The advantage is obvious: it's bigger. On mobile, a portrait image fills more of the vertical screen space, making it much harder to just scroll past. That extra height gives your content a powerful presence.

Time and again, we see posts with square and portrait images outperform others on LinkedIn. Square gives you consistency, while portrait gives you a competitive edge on mobile where most users are scrolling.

Pro-Tip: LinkedIn technically accepts other image sizes for the feed, but if you want your visuals to look sharp and clear, stick to either 1080×1080 or 1080×1350 pixels. This prevents the platform from compressing or stretching your image in weird ways.

At the end of the day, picking the right image size for LinkedIn posts is less about following a rule and more about making a strategic choice. But remember, the perfect size is only half the battle. You still need compelling visuals as a foundation for creating engaging social media content that truly connects with people. My advice? Test both formats and see what your audience responds to best.

Nailing Your Images for Shared Links and Articles

When you drop a link into a LinkedIn post, the platform automatically pulls in a preview with a title, a short description, and an image. That little thumbnail is your first impression—and it’s often the deciding factor on whether someone clicks through. Getting that visual right is a non-negotiable for driving traffic.

The gold standard for these preview images is 1200 x 627 pixels. This isn't just a random number; it's the ideal 1.91:1 aspect ratio that LinkedIn loves. Sticking to these dimensions means your image will look sharp and professional, without any weird or awkward cropping that could chop off your headline or key parts of the graphic. It’s optimized to look great everywhere, from a wide desktop monitor to a vertical mobile screen.

Taking Charge with Open Graph Tags

So, how do you make sure LinkedIn picks the right image? You can’t just hope for the best. The secret is in your website’s code, specifically a piece of metadata called the Open Graph (og:image) tag.

By setting this tag in your webpage’s HTML, you're essentially giving LinkedIn direct instructions on which image to feature in the preview. It’s a simple piece of code that puts you completely in control.

Instead of letting LinkedIn grab a random, often poorly-suited image from your page, you can hand-pick the perfect visual that aligns with your content. Mastering this is a key part of learning how to post an article on LinkedIn like a pro.

Mastering Your Profile and Company Page Images

Think of your LinkedIn profile and company page as your brand's digital front door. The images here are the first thing people see—your virtual handshake. They set the tone for potential clients, new hires, and professional connections, so getting them right is absolutely critical for building credibility.

These aren't just decorative elements; they're foundational pieces of your professional identity. Each one has a specific job to do, whether it's putting a face to a name or showing off your brand's personality in a single glance.

Key Branding Image Dimensions

Let's get straight to the numbers for the three most important branding images on LinkedIn.

• Personal Profile Picture: Aim for 400 x 400 pixels. This is your main identifier across the platform, so make it a crisp, professional headshot. No blurry vacation photos here!

• Company Page Logo: The minimum size is 300 x 300 pixels. This ensures your logo looks sharp everywhere, from search results to your followers' feeds.

• Cover Photos (Banners): The sizes differ depending on the page. For a personal profile, the banner should be 1584 x 396 pixels. For a company page, it's a bit smaller at 1128 x 191 pixels.

Here's a pro tip for cover photos: always account for where your profile picture will sit. On a desktop view, your photo covers the bottom-left portion of the banner. Be careful not to place any important text, logos, or design elements in that spot, or they’ll be completely hidden.

Keeping all your visuals consistent and high-quality is a huge part of brand management. To stay organized, it helps to have a solid digital asset management workflow. This ensures your team can always find the right on-brand images, perfectly sized. Using the correct image size for LinkedIn posts and profiles makes your brand look polished and professional, every single time.

Winning with LinkedIn Video and Carousel Posts

Static images get the job done, but if you really want to stop the scroll and tell a deeper story, video and carousels are where it's at. These dynamic formats need their own set of dimensions to look sharp and give users a great experience. Getting the technical specs right is the first step to making content that genuinely connects.

When you move beyond a single image, you can show off multiple products, break down a complex topic, or just create a more engaging, interactive post. Let’s dive into the specs you need to know.

LinkedIn Video Specifications

Video is a fantastic format on LinkedIn, but it comes with more technical rules than a simple image. To sidestep any weird cropping or playback problems, stick to these guidelines:

• File Size: Your video file should be between 75 KB and 200 MB.
• Duration: Keep your videos between 3 seconds and 10 minutes long.
• Aspect Ratio: LinkedIn is pretty flexible, supporting a range from 1:2.4 to 2.4:1. The most reliable formats are landscape (16:9) and square (1:1). For mobile-first content, vertical video (9:16) also works well. For a closer look, see our guide on vertical video dimensions.

Designing Effective Carousel Posts

Carousels are essentially mini-slideshows in a single post, making them perfect for tutorials, listicles, or telling a brand story. They get users to stop and swipe through your content, which is a big win.

The real secret to a great carousel is consistency. When you use the same image size for every single card, you create a smooth, seamless swiping experience. If your cards have different dimensions, LinkedIn often slaps on a distracting gray background to fill the gaps.

For the best results, design every card in your carousel to be 1080 x 1080 pixels. That's a perfect 1:1 square aspect ratio. This format looks clean and professional on both desktop and mobile, making your content easy to follow from the first slide to the last.

Getting Your LinkedIn Ad Images Just Right

When you're putting money behind an ad on LinkedIn, getting the visuals right is non-negotiable. It's about more than just looking good; it's about making your ad spend work harder. The platform has strict guidelines for ad images, and ignoring them can lead to some seriously awkward results.

Think weird cropping, blurry logos, and a click-through rate that tanks your entire campaign. To make sure every dollar counts, you need to know the specific requirements for each ad format. Let's dig into the details.

Single Image and Carousel Ad Sizes

Single Image Ads are the bread and butter of many LinkedIn campaigns. They're straightforward and effective, but you have to nail the dimensions. The sweet spot is 1200 x 627 pixels, which gives you that familiar 1.91:1 rectangular aspect ratio. This size looks sharp and professional across almost every placement in the LinkedIn network.

Carousel Ads are a different beast. They let you tell a story with multiple swipeable images, but the key to a good carousel is consistency. Every single image card needs to be a perfect square to create a smooth, seamless experience for the user.

• Recommended Resolution: 1080 x 1080 pixels for each individual card.
• Aspect Ratio: A perfect 1:1 ratio is a must for all cards.
• File Size: Make sure each image is under 10 MB.

Keeping every card a uniform square is crucial. It stops the user's swiping experience from feeling disjointed and makes your entire message look more polished and intentional.

Sponsored Messaging and Text Ad Dimensions

Beyond the main feed, other ad placements have their own unique image needs. If you're using Sponsored Messaging (what used to be called InMail), you can include a banner creative right inside the message.

• Sponsored Messaging Banner: The only size that works here is 300 x 250 pixels.

Then you have Text Ads, those compact ads that show up on the desktop view, usually in the right-hand column or at the top of the page. The image is small, but it's your best shot at grabbing someone's attention.

• Text Ad Image: A simple 100 x 100 pixel square is all you need.

By mastering these different ad specs, you ensure your campaigns are optimized for every corner of LinkedIn, which ultimately boosts performance and protects your brand's professional image.

Common Image Pitfalls and How to Sidestep Them

Getting the dimensions right is half the battle, but there are a few other common trip-ups that can make an otherwise perfect post look amateurish. We’ve all seen it: fuzzy text, weirdly cropped photos, and images that just don't pop.

The good news is that these issues are surprisingly easy to fix. A little know-how goes a long way.

One of the biggest culprits behind blurry images? The file format. People often default to JPEG for everything, but that can be a mistake, especially for graphics. JPEGs are great for shrinking photo file sizes, but they achieve this by ditching some of the image data—what's known as "lossy" compression. That's fine for a photograph, but for crisp text and logos, it's a recipe for fuzzy edges.

Choosing the Right File Format

Think of it like this: you wouldn't use a hammer to turn a screw. You need the right tool for the job.

• Use PNG for graphics with text: If your image has any text, a logo, or sharp lines, always save it as a PNG. PNG is a "lossless" format, which means it keeps all the original data, so your graphics stay sharp and clear. No weird artifacts, no blurry text.
• Use JPEG for photographs: When you're just sharing a photo, like a new headshot or an event picture, a high-quality JPEG is the way to go. You'll get a smaller file size, which helps your page load faster, without any noticeable drop in quality.

Another classic mistake is forgetting about mobile viewers. That beautiful graphic you designed on your giant desktop monitor can easily become a squint-inducing mess on a phone screen.

Always design with a "mobile-first" approach. This means using large, clear fonts and high-contrast colors that are easy to read on a small screen. Before you hit "post," do a quick check on your own phone. It’s the best way to catch readability problems before your entire audience does.

Got Questions About LinkedIn Image Sizes? We've Got Answers.

Even when you have all the correct dimensions, a few practical questions always seem to pop up. Let's tackle some of the most common ones that people run into when getting their LinkedIn images just right.

Think of this as your quick-reference guide to solve those nagging little issues that can make or break the look of your profile and posts.

What’s the Best File Format to Use for LinkedIn Images?

This really depends on the type of image you're uploading.

For anything with sharp lines, text, or logos, go with PNG. It keeps your graphics perfectly crisp and clear without any of that annoying blurriness. But for photos—like your headshot or pictures from an event—a high-quality JPEG is usually the better bet. It gives you a smaller file size, which helps things load faster, without sacrificing much visual quality.

Why Does My Image Look Different on Mobile vs. Desktop?

Ah, the classic cover photo problem. This happens because LinkedIn has to crop your banner to fit different screens. The wide, panoramic view you see on a desktop monitor gets squeezed down and cropped significantly on a narrow mobile phone.

The trick is to keep all your essential stuff, like your logo or any important text, right in the middle of the image. This central "safe zone" ensures the most critical parts of your banner won't get cut off, no matter what device someone is using.

Should I Go Back and Update Old Posts with the New Image Sizes?

Nope, you can leave your old content as is. LinkedIn's image specs don't change all that often, and older posts are generally fine.

Just focus your energy on using the current, recommended dimensions for all new content you create. That's the best way to make sure everything you publish from now on looks sharp and professional.
