The feed on LinkedIn can be frustratingly selective, often leaving out posts that seem relevant to you. This is largely due to the algorithm's focus on engagement, which it measures against image sizes. When an image is the right size, it shows up more clearly and engages viewers for longer.
What Image Size Should You Use?
In 2026, LinkedIn favors images sized 1200 × 1200 pixels, which is especially important for standard posts. This is different from the 1080 pixels that are commonly used on other platforms. If you use an image in the wrong size, it could be cropped or pixelated, or simply not appear in the feed, leading to missed opportunities to connect with relevant content.
For promotional images, the ideal size is 1200 × 627 pixels, and 400 × 400 pixels for profile pictures. This matches the maximum width that LinkedIn allows in the feed, preventing distortion or cropping.
If your image doesn’t fit the recommended size, the feed might automatically adjust it, which could cut off vital details and make it less appealing.
Can the Wrong Image Size Hurt Ethical Social Selling Signals?
Ethical social selling is contingent on trust. Using the wrong sized image can damage this by looking unprofessional or hiding important information. If the image is blurry or cut off, it might make viewers doubt the credibility of the message, which could lead to them "suppressing" the post.
You can tell if an image is poorly sized by looking for things like a black bar on the sides, cut-off text, or a blurry background. Such flaws can drive down engagement and make the algorithm think the post isn't worth showing. You can check if an image is sized correctly by zooming in on the post in a desktop preview; if the dimensions are off, re-uploading a properly sized version can help restore visibility and signal that you are ethically selling.
Should I prioritize quality or quantity for LinkedIn networking?
LinkedIn networking benefits from a balance between quality and quantity. Posting too much with low-resolution images can clutter the feed, making each post less impactful. Alternatively, a few high-quality posts with sharp visuals can lead to longer engagement and more meaningful interactions. Buffer’s 2026 guide advises keeping file sizes within reasonable limits to maintain image quality without sacrificing speed. Sticking to the right dimensions and file sizes can also streamline your process and keep your visuals consistent.
In conclusion, the way to keep your LinkedIn posts visible is to use the right size images, particularly the 1200 × 1200 pixels square for standard posts. This not only improves algorithmic visibility but also supports your case for ethical social selling.
