A thumbnail image is a small preview image that represents a larger image or video file. On LinkedIn, thumbnails are used in posts to give viewers a visual preview of the content being shared. When you share things like images, infographics, videos or documents on LinkedIn, a thumbnail will automatically be generated. Understanding how thumbnails work on LinkedIn can help you optimize your content to drive more visibility and engagement.
How Thumbnails Are Generated on LinkedIn
When you upload an image, video or document to LinkedIn, their system will automatically generate a thumbnail preview. Here is how it works for different content types:
- Images – LinkedIn will crop your image to a square and use that as the thumbnail.
- Videos – LinkedIn will select a frame from the video to use as the thumbnail. This is usually taken from near the start of the video.
- Documents – LinkedIn will extract the first page of the document and use that as the thumbnail.
For images and documents, LinkedIn will look for the most visually appealing and information-rich areas to showcase in the thumbnail. The goal is to feature parts of the image or document that will entice viewers to click through and view the full content.
Customizing Your LinkedIn Post Thumbnails
When you are creating a LinkedIn post, you have some options to customize the auto-generated thumbnail:
- Upload a custom thumbnail – You can upload your own image to use as the thumbnail instead of relying on LinkedIn’s auto-generated version. This allows you to carefully craft a thumbnail that aligns with your branding and communicates your key message.
- Rearrange auto-generated thumbnails – For posts with multiple images or videos, you can reorder the thumbnails displayed. Put your most eye-catching visual first to improve clickthrough rates.
- Delete auto-generated thumbnails – If you don’t want a particular image or document preview to be shown, you can remove it from the selection of thumbnails.
Taking advantage of these customization options is important. The thumbnail is the very first thing viewers see before deciding whether to engage with your post. An appealing and strategic thumbnail can dramatically improve your post’s performance.
Thumbnail Size and Specs
On LinkedIn’s desktop website, post thumbnails appear with the following specs:
- Shape: Square
- Dimension: 90 x 90 pixels
On mobile devices, the thumbnail dimensions are a bit different:
- Shape: Horizontal rectangle
- Dimensions: Approx. 125 x 83 pixels
If you want to design a custom thumbnail, create one at these sizes to ensure it displays properly across devices. The thumbnail’s shape and orientation will shift slightly when displayed in the LinkedIn feed based on how LinkedIn crops it.
Keep in mind the small size. Your custom thumbnail needs to clearly convey your key visual message in a tiny 90 x 90 pixel or 125 x 83 pixel image. Prioritize visual simplicity and high contrast.
Thumbnail Design Best Practices
Follow these best practices when designing custom thumbnails for your LinkedIn posts:
- Showcase a compelling, recognizable visual – Choose an image that is eye-catching and draws attention at a small size. Brand logos, products, text graphics and simple data visualizations tend to work well.
- Use high contrast colors – With such a small image, you need strong contrast between foreground and background elements so details don’t get lost.
- Include minimal text – You have very limited space, so only include essential text. Your company name or post headline keywords are ideal. Avoid long bodies of text.
- Align with your brand – Use colors, fonts, logos and visual style that are on-brand so your thumbnails are instantly recognizable.
- Optimize Legibility – Preview your thumbnail at actual size to ensure text and design elements are legible. Zoom way in when designing to see how it looks at 90 x 90 pixels.
- Enhance with design – Consider adding design touches like borders, photographic style, geometric shapes or illustrations to make your thumbnail pop.
The Importance of Optimized Thumbnails
It’s worth investing time into crafting optimized thumbnails. Your thumbnail is one of the biggest factors that will determine whether someone engages with your LinkedIn post or keeps scrolling. Consider these thumbnail statistics:
- Posts with thumbnails see 2X more engagement than posts without.
- Posts with customized thumbnails get 10% more engagement than those with auto-generated ones.
- Viewers decide whether to click on a post in just 1.7 seconds by looking at the thumbnail and headline together.
Your thumbnail gives you a prime opportunity to catch viewers’ attention and direct them into your post. An eye-catching, optimized thumbnail signals that your content is high-quality and worth their time.
Examples of Effective LinkedIn Post Thumbnails
Here are some examples of LinkedIn posts with strategic thumbnail design:
Brand Logos
Many companies successfully use their brand logo as the thumbnail. It builds brand visibility and recognition for your content in the LinkedIn feed.
Data Visualizations
A thumbnail with a simple data visualization attracts viewers by conveying key insights at a glance before they even click through.
Text Graphics
Text graphics allow you to feature a compelling headline or message as the thumbnail to highlight what the content is about.
Product Imagery
For product-focused content, use an eye-catching image featuring your product as the thumbnail to spark interest.
Behind-the-Scenes
A thumbnail with a photo showing behind-the-scenes workings of your company or team helps convey authenticity.
Featured Employees
Putting an employee’s photo in the thumbnail makes content more relatable and humanized.
Conclusion
Optimizing your LinkedIn post thumbnails is a valuable tactic to drive engagement. Take advantage of the ability to upload custom thumbnails that align with your brand and resonate visually. Follow best practices when designing thumbnails, prioritizing compelling visuals, simplicity, and strong contrast. With strategic thumbnail design, you can significantly boost views, likes, comments, and clicks for your LinkedIn content.
