On LinkedIn, it's essential to capture your audience’s attention with compelling text, but visuals play an equally important role.
In today’s feed, an image is not just a supporting element—it acts as a powerful activator, similar to a captivating headline.
Knowing the ideal size for your LinkedIn images is key to optimizing your content.
By ensuring your visuals fit perfectly, you can make the most of the screen space and create the desired impact.
TL;DR: To make your LinkedIn profile and posts stand out, it’s key to use the right image sizes. Here’s the ideal sizing for the best results:
Profile Photo: 400 x 400 px
Profile Banner: 1584 x 396 px
Single Image Post: 1200 x 627 px
Square Post: 1080 x 1080 px
Carousel Post: 1920 x 1080 px
Link Thumbnail: 1200 x 628 px
Article Featured Image: 1200 x 644 px
Article Banner Image: 600 x 322 px
Vertical Video Size: 1080 x 1920 px
Getting the right image size on LinkedIn is crucial, no matter what type of content you're posting.
The size of your image directly impacts how much screen space it occupies.
Bigger images tend to grab more attention, as they dominate the user's feed.
This plays into both UI (User Interface) and UX (User Experience): a properly sized image seamlessly fits into LinkedIn's layout, creating a visually appealing experience for the audience.
On the other hand, an image that's too small or poorly optimized can get lost in the feed, causing your post to be easily overlooked.
Let’s break down why visuals are so important and what can happen if your images aren't properly sized for LinkedIn.
The Role of Visuals on LinkedIn
Every time we open LinkedIn, we’re greeted with a mix of formats—videos, carousels, personal photos, and even visuals within articles.
These formats are everywhere because they work: visuals create an instant hook, grabbing attention faster than text ever could.
People naturally connect more quickly with something they can scan in less than a second, rather than committing to reading a post.
That’s why, while your text should always be engaging, it’s equally crucial to pair it with a powerful, well-sized image that complements your message and represents your brand in the best possible light.
In essence, a striking visual isn’t just an add-on; it’s a tool to ensure your post stands out and drives engagement.
Consequences of Incorrect Image Sizes
Unfortunately, even today, many LinkedIn users overlook the importance of properly sizing their images.
This leads to posts with visuals that aren’t optimized for their format.
When images are the wrong size, text can become too small, the visuals fail to grab attention, and the overall post looks unappealing.
This lack of polish results in reduced visibility, as people are less likely to engage with something that doesn’t look visually compelling.
Even worse, poorly sized images can hurt your brand’s credibility.
A sloppy or unprofessional visual can make it harder for your audience to take your message seriously, ultimately impacting your reach and influence on the platform.
Ideal LinkedIn Post Photo Sizes
Now let’s get to the important part—what are the ideal image sizes for posting on LinkedIn?
The answer depends on what type of content you’re sharing.
General Guidelines for LinkedIn Images
The size of your images will vary depending on the format of your post.
To make things easier, it’s a good idea to either keep a cheat sheet of LinkedIn’s image dimensions handy or label your design files with the specific post type they’re meant for.
If you’re not familiar with LinkedIn’s image size requirements, here’s a general guideline to follow:
A single image post may need different dimensions than a carousel, video thumbnail, or banner.
Image Sizes for LinkedIn Posts
Now, let’s get to the nitty-gritty of what you really need to know: the proper image sizes for LinkedIn posts.
It’s important to note that the right size depends on the type of content you’re posting.
For a regular single image post, the ideal size is 1200 x 627 px. This size works great for horizontal images, ensuring they look sharp and fit properly in the feed.
If you prefer to share a square image, the best size is 1080 x 1080 px. This is perfect for a balanced look and works across devices.
For carousel posts, the recommended size is 1920 x 1080 pixels. This size is optimized to occupy a good amount of space on both mobile and desktop, making it easy for users to scan and engage with each slide.
Finally, for portrait images, the ideal size is 1200 x 1200 px. This vertical format works well for posts where you want to highlight specific details or create a more dynamic visual effect.
But there are also many other formats to consider for different types of content:
4Article Featured Image: 1200 x 644 pixels
Article Banner Image: 600 x 322 pixels
Blog Post Link Images: 1200 x 627 pixels
Carousel Posts: 1080 x 1080 pixels or 1920 x 1080 pixels
Preferred Format for Carousel: PDF
Video Vertical Size: 1080 x 1920
Video File Size: 75KB to 200MB
Maximum Video Length: 10 minutes
By following these recommended sizes, your images will look crisp, professional, and visually engaging, whether viewed on mobile or desktop.
Sizes for LinkedIn Link Thumbnails
When sharing links on LinkedIn, the image preview plays a significant role in grabbing attention.
The ideal size for link thumbnails is 1200 x 628 pixels.
This size ensures that your image displays correctly and looks sharp across different devices and screen sizes.
Additionally, the image should be relevant to the content you're sharing.
Choose an image that aligns with the link’s content to make it more engaging.
LinkedIn Profile Photo and Banner Sizes
Another crucial element that is often overlooked is the profile photo and banner next to your profile.
These images need to be optimized because they create the first impression—not only based on your content, but also on who you are, what you offer, and the overall impact you make.
A well-done profile photo and banner with a clear call to action can boost your engagement and help attract more clients if that’s your goal.
On the other hand, if they are not optimized, you’re missing out on a key opportunity to stand out.
Profile Photo
First and foremost, your profile photo is essential.
This is one of the first images people will see, so it’s important to make a good impression.
You should be smiling in the photo, and it must look professional.
However, avoid pictures where you're on vacation or with friends—it's important to find the balance between being approachable and professional.
The ideal photo size is 400 × 400 px, and the preferred formats are JPEG or PNG.
If your photo is too large, there are techniques to compress it without losing quality.
Keep in mind that LinkedIn has size limitations for images, so it's important to make sure your photo doesn’t end up being too heavy to upload.
LinkedIn Banner
When it comes to your LinkedIn banner, it’s crucial to make sure it’s both visually appealing and professional.
The ideal dimensions for your banner image are 1584 x 396 pixels. This size ensures it displays properly on all devices without distortion.
Here are some tips for creating a professional-looking banner:
Keep it simple: A clean, minimalistic design works best. Avoid cluttered images or too much text.
Branding: If you have a personal brand or company logo, include it in your banner to make your profile stand out.
Consistency: Ensure your banner complements your profile photo and reflects your professional identity.
Quality: Use high-quality images, but make sure the file size is optimized for LinkedIn’s upload limits.
