LinkedIn Article Header Image Size Guide for 2026
Publishing an article on LinkedIn is a powerful way to build professional credibility and reach. The header image is the first thing readers see in their feed — getting the size right makes the difference between a professional, eye-catching post and one that looks cropped or blurry.
LinkedIn Article Header Image Size
The recommended LinkedIn article header image size is 1200 × 644 pixels, which is a ~1.86:1 aspect ratio. LinkedIn accepts images up to 8 MB. The image appears as a wide banner at the top of your article and as a thumbnail in the feed and on your profile. Keep your key content centered to avoid cropping in different display contexts.
LinkedIn Newsletter Cover Image Size
LinkedIn Newsletter cover images use the same recommended dimensions as articles:1200 × 644 pixels. This image is prominently displayed when subscribers receive the newsletter notification. A high-quality, relevant cover image significantly improves open rates.
Supported File Formats
LinkedIn article header images support JPG, PNG, and GIF. For static header images, JPG is recommended because of smaller file sizes. If your header image requires transparency (e.g., a logo on a transparent background), use PNG. Avoid GIF unless you specifically want an animated header.
How to Prepare Your LinkedIn Article Image
Start with a high-resolution source image and resize it to 1200 × 644 pixels using the free Image Resizer. If your source image has a different aspect ratio, use the Image Cropper to crop it to the correct ratio before resizing. Compress the final image to under 500 KB using the Image Compressor for fast loading.
Design Tips for LinkedIn Article Headers
A strong LinkedIn article header image increases click-through rates. Here are design principles that work well:
- Use bold, readable text overlaid on the image if you include a title
- Keep important elements away from the edges to avoid cropping in thumbnails
- Use high-contrast colors that stand out in a busy LinkedIn feed
- Stick to a consistent visual style across your articles for brand recognition
- Avoid stock photos that look generic — real photos or custom graphics perform better
LinkedIn Feed Preview vs. Article View
When your article appears in the LinkedIn feed as a share or notification, the header image is cropped and displayed as a thumbnail. LinkedIn typically shows a ~1.91:1 ratio thumbnail for links, which is slightly different from the article header ratio. To ensure your image looks good in both views, place your main subject and text in the center third of the image.
LinkedIn Profile Featured Images
If you feature an article in the Featured section of your LinkedIn profile, the image thumbnail is displayed at approximately 300 × 200 pixels. Keep this in mind when designing header images — your core message should be visible even in this smaller format.
A well-crafted LinkedIn article header image is a professional signal that sets the tone for the quality of your content. Use the right dimensions and compress properly for the best reading experience.
