First impressions are vital in a professional setting, especially when we're talking about LinkedIn, the most influential professional network platform on the planet.

Professionals, business leaders, salespeople and directors, small businesses, and large brands alike need to post content that engages, encourages conversations, and drives conversions. This means creating high-quality posts, showcasing brand assets, and engaging with your network. 

This means making sure you get the basics right, starting with the sizes of images, videos, and other visual content assets. 

In this article, we provide a complete LinkedIn post size guide, so you have all the details you need to stand out on the platform.

Why does LinkedIn post size matter?

LinkedIn is a B2B (business-to-business) professional networking platform, but it’s still a social media website. You need to remember that when designing your LinkedIn marketing strategy.

That means visuals play a significant role. Although users are on LinkedIn for a different reason from Instagram or TikTok, people still scan, scroll, and consume information in the same way. 

Businesses rely on LinkedIn to establish their brand, showcase expertise, and engage with their target audience, also known as Ideal Customer Profiles (ICPs). Businesses and professionals on LinkedIn do this by sharing updates, images, articles, videos, and insights, all of which rely on strong visuals to make an impact. 

Alongside the vast global audience, every minute on LinkedIn (as of November 2025):

• 93: People add a new role to their profile
• ~9.5K: Job applications are submitted
• 1.9M+: Feed updates are viewed
• 17K+: Connections are made
• ~155: Hours of learning content is consumed

As a professional platform, LinkedIn is the market-leader, and this is why you need to post engage visual (and written) content as often as you can. 

Whether you’re a freelancer or part of a global organisation, LinkedIn post size matters. Here are a few more reasons why. 

• Optimised reach: When your content is correctly formatted to LinkedIn’s guidelines, it appears on the feed exactly how it should look. This reduces the chance of key components being cropped out or overlooked. It also means you’ll look professional, and that makes a big difference on LinkedIn.
  
  For example, a header image with the wrong dimensions might cut off an important message or a chunk of your logo.
  
  
• Visual appeal: Simply put, posts that look good are more likely to catch the attention of viewers. Formatting is a big part of this. Creating a professional, polished piece of content gives your post greater visual appeal, improving its chances of gaining traction.
  
  
• Improved engagement: As a networking platform, LinkedIn is a useful platform to generate B2B engagement. Users support one another through likes, comments, and, more importantly, shares. Posts that are carefully designed with the correct dimensions are more likely to garner engagement.
  
  LinkedIn’s algorithm promotes content that drives higher engagement. So, getting the LinkedIn post size right should be a priority.
  
  
• Branding consistency: Using the correct post sizes helps with branding by making sure key elements, like logos, colours, and text, are always visible. This is crucial for maintaining consistency, which builds familiarity and trust with your network over the long term.
  
  
• Better mobile experience: Almost 60% of LinkedIn traffic comes from mobile users. Uploading content in line with the guidelines ensures your posts are optimised for mobile and desktop users. Getting it right the first time helps you avoid time-consuming edits, cropping, and resizing.

Investing in social media management software with built-in image editing is a smart investment. It makes post-optimisation easier and provides access to a range of useful features, including scheduling tools, collaboration tools, and data analytics.

Other than its built-in image editor that enables you to resize and tailor your images, Sendible integrates with one of the most popular image and video editing platforms on the market, Canva.

This means you can create, edit, optimise, schedule, and monitor LinkedIn posts from one place. Plus, you can use its interactive calendar to manage social media content for all major platforms.

The complete LinkedIn post size guide for 2026

Visual content on LinkedIn covers everything from an image posted with an article (linked or uploaded), to carousels, videos, adverts, and documents. 

Everyone also has space for a personal profile header image, a bio image, and company pages have space for logos and header images.

Every single one of these needs to be formatted in a different size. Nor can you simply re-post images from other social platforms because they have different size requirements, so it’s important you get the ones you’re using for LinkedIn right. 

In this guide, we provide the key specifications of each LinkedIn post type, helping you maximise visual appeal while maintaining a professional look.

Top tips for perfecting your LinkedIn visuals

Below are some top tips and best practices, based on the most up-to-date information possible within this ultimate guide:

• Design for the right LinkedIn post size to prevent cropping, stretching, or poor-quality images appearing across desktop and mobile.
• Choose dimensions based on intent: Use 4:5 for mobile-first reach, 1:1 for versatile feed posts, and 1.91:1 for links and sponsored content.
• Keep text within a “safe zone” (centre-aligned and away from edges) to avoid losing essential messaging when LinkedIn auto-crops previews.
• Optimise visual clarity by exporting images at a minimum of 1200px width and uploading high-resolution MP4s for videos.
• Reduce clutter: Use clean compositions, strong contrast, and minimal on-image text so the visual stands out in fast-scrolling feeds.
• Be consistent with branding using the same colours, fonts, logo placement, and style across all post sizes to reinforce recognition. Make sure it’s the same branding as on your website and other social networks.
• Prioritise mobile users (who make up nearly 60% of LinkedIn traffic) by testing every visual in mobile preview before uploading.
• Use templates for efficiency. Create preset Canva or editing tool templates for each LinkedIn post size so your team stays consistent.
• Add captions and subtitles to videos to boost accessibility and improve watch-time, especially for silent autoplay in the feed.
• Test and refine: Monitor which sizes and formats drive higher engagement, then optimise future visuals based on performance trends.
