Master the Feed: The Ultimate Guide to LinkedIn Post Image Sizes

When you’re scrolling through LinkedIn, what makes you stop? Usually, it’s a striking visual paired with a compelling hook. But there is nothing quite as frustrating as crafting a brilliant graphic, uploading it to your professional profile, and watching LinkedIn awkwardly crop out your headline, your face, or your data points.

Using the correct dimensions isn’t just about aesthetics—it’s about respect for your audience’s experience and maximizing your reach. Here is your complete, go-to cheat sheet for nailing LinkedIn post image sizes every single time.

1. Standard Feed Post Image Sizes

LinkedIn supports a few different aspect ratios for standard image posts. Depending on the vibe of your content—whether it’s a data-heavy infographic or a sleek team photo—choose one of these optimal formats:

• Square (1:1 Ratio): 1080 x 1080 pixels
  • Why use it: This is the gold standard for the feed. It balances well on both desktop monitors and mobile screens, giving you equal height and width so your content never gets unexpectedly clipped.
• Landscape (1.91:1 Ratio): 1200 x 627 pixels
  • Why use it: Perfect for wide landscape photos, landscape illustrations, or automated link preview thumbnails when sharing articles and blogs.
• Vertical / Portrait (4:5 Ratio): 1080 x 1350 pixels (or up to 1200 x 1500 pixels)
  • Why use it: If you want to command maximum mobile screen real estate, vertical posts are your best friend. They push surrounding text further down on mobile feeds, forcing users to interact with your graphic.

2. Special Post Formats: Carousels and Documents

Document posts (often uploaded as PDFs that turn into swipeable carousels) are massive engagement drivers on LinkedIn.

• Carousel / Document Size (Square): 1080 x 1080 pixels (1:1 ratio)
• Carousel / Document Size (Portrait): 1080 x 1350 pixels (4:5 ratio)
• Pro-Tip for Documents: Always export your slide decks or PDFs with crisp text and keep vital text elements away from the very edges so they remain readable inside the viewer interface.

3. Quick Reference: Profile & Cover Assets

While post sizes get your content seen, your profile framing establishes your credibility. Make sure your overall page layout is pristine with these dimensions:

| Asset Type | Recommended Dimensions | Aspect Ratio |
| :— | :— | :— |
| Personal Profile Picture | 400 x 400 pixels | 1:1 (Square, cropped to a circle) |
| Personal Cover Photo | 1584 x 396 pixels | 4:1 (Landscape) |
| Company Page Logo | 300 x 300 pixels | 1:1 (Square) |
| Company Cover Photo | 1128 x 191 pixels | ~6:1 (Ultra-wide) |

Crucial Mobile Safe Zone Tip: Personal and company banners crop dynamically on mobile devices. Keep all important logos, taglines, and text elements centered safely within the middle portion of your banner to avoid awkward clipping on phones and tablets.

4. Technical Rules of Thumb

To ensure LinkedIn doesn’t auto-compress your crisp designs into a pixelated blur, keep these technical boundaries in mind:

• File Formats: Stick to PNG for graphics containing heavy text, UI elements, or logos to keep edges sharp. Use JPEG for photographs and complex images to keep file sizes manageable.
• File Size Limits: Keep standard post images under 5 MB.
• Resolution: Always design at higher resolutions (like 1080p or 1200p minimum width) so your images look sharp on high-definition retina displays.

By sticking to these precise dimensions, you take the guesswork out of publishing. Clean lines, correct formatting, and professional execution ensure your insights take center stage—right where they belong.
