What Are the Best LinkedIn Ad Sizes for Mobile and Desktop?

Introduction: Why Ad Sizes Matter on LinkedIn

In the realm of professional networking, LinkedIn stands out as a powerhouse for B2B marketing and career-oriented advertising. As digital advertising becomes increasingly refined, understanding the impact of ad sizes on LinkedIn—both on mobile and desktop platforms—is crucial for marketers aiming to target professionals effectively. This article explores the essential ad sizes for LinkedIn and discusses why these dimensions are vital for maximizing your advertising success.

LinkedIn Ad Formats and Optimal Sizes

Sponsored Content: The Backbone of LinkedIn Advertising

LinkedIn Ad Sizes - Mobile

Sponsored Content on LinkedIn appears directly in the user feed, mimicking organic posts but with a broader reach. It's crucial these ads are visually appealing and appropriately sized to ensure they capture the attention of professionals scrolling through their feed.

- Mobile and Desktop Dimensions:
 - Single Image Ads: 1200 x 627 pixels
 - Carousel Ads: Each card within the carousel should be 1080 x 1080 pixels

Ensuring these ads are the right size helps maintain clarity and engagement, preventing image distortion or unwanted cropping across different devices.

LinkedIn Ad Sizes - Desktop

Text and Dynamic Ads: Precision in Minimalism

Text and Dynamic Ads on LinkedIn offer a more straightforward approach to advertising, where the focus is more on the message than on the visual content.

- Recommended Sizes:
 - Text Ads: Minimum of 100 x 100 pixels for the accompanying image
 - Dynamic Ads: Typically use a user’s profile photo, which is automatically formatted by LinkedIn

These ad types are less about visual impact and more about targeting and personalization, yet proper sizing ensures that they integrate seamlessly into the professional environment of LinkedIn.

Video Ads: Engaging the Professional Audience

Video ads on LinkedIn are an effective way to engage users more deeply, offering dynamic content right in the feed.

- Optimal Video Sizes:
 - Aspect Ratio: 16:9 for horizontal videos, though square (1:1) and vertical (9:16) formats are also supported
 - Resolution: At least 720p to ensure high-quality playback on both mobile and desktop platforms

Adhering to these specifications ensures that your video content delivers the intended impact without technical hitches that could detract from the user experience.

The Significance of Proper Ad Sizing on LinkedIn

Enhanced Professional Perception

LinkedIn is a platform where professionalism is paramount. Ads that are well-sized and formatted not only fit better within the user interface but also convey a sense of professionalism and attention to detail that resonates with the target audience.

Optimized User Experience

Properly sized ads enhance the user experience by providing clear, engaging content that doesn’t require zooming or scrolling to view in full. This ease of interaction leads to higher engagement rates, as professionals are more likely to interact with content that respects their time and platform usability norms.

Improved Ad Performance

Correct ad sizing directly correlates with improved performance metrics such as click-through rates, engagement, and conversions. Ads that are optimized for both mobile and desktop viewing ensure maximum visibility and impact, aligning with LinkedIn’s algorithm preferences for well-formatted content.

Conclusion: Mastering LinkedIn Ad Sizes for Better ROI

For marketers and advertisers, mastering LinkedIn ad sizes is not just about following guidelines—it's about leveraging every aspect of the ad’s visual and textual elements to connect effectively with a professional audience. By understanding and implementing the correct ad sizes for LinkedIn, brands can significantly enhance their digital advertising efforts, driving both engagement and ROI.


Ad sizes on LinkedIn are a critical component of successful digital marketing campaigns on the platform. As you aim to optimize your presence in the professional world, consider utilizing tools like, which can help ensure your ads are always up to standard, boosting your strategy’s effectiveness and efficiency.

It saved me hours

When I discovered this tool I pretty much saw it as magic. It saved me hours, gave me lots of new graphics to use, and was easy to get started with. The only thing I'd change is having the option to get specific sizes for use in advertising where I need 4-5 variations. The sizes at the time that were offered are just horizontal, square, vertical, but I need to be exact with my measurements.

The quality of the AI blew me away

I have been doing creative design for the past 8 years and I can tell you that this app is different. The quality of the AI blew me away, as I never use these features because from my experience they are always just BAD. The technology doesnt work yet and the results are... not good :) In case of adcreative the AI tool is saving me so much time and I use these designs to deliver advertisements for my clients who are promoting 6 and 7 figure businesses. That means these designs work and can run a business, can't tell that about any other app. Enterprise Enterprise Program, a bespoke solution tailored for businesses seeking to boost
