The Ultimate Guide to LinkedIn Image Sizes: Dominate the Feed in 2026

First impressions on LinkedIn happen in milliseconds. Long before a potential client, employer, or partner reads your carefully crafted headline or multi-paragraph post, their eyes catch your visuals. A crisp profile picture, a striking background banner, and a well-proportioned post graphic instantly signal professionalism and competence. Conversely, a pixelated headshot or an awkwardly cropped image tells the algorithm—and your audience—that details don’t matter.

Because over 60% of LinkedIn traffic originates from mobile devices, understanding how your images render across different screen sizes is no longer optional. This comprehensive cheat sheet covers every dimension you need to keep your personal brand and company page looking razor-sharp.

1. Personal Profile Visuals

Your personal profile is your digital handshake. These core graphics set the tone for your online presence.

• Profile Photo: 400 × 400 pixels (minimum)
  • Aspect Ratio: 1:1 (Square, cropped into a circle)
  • Max File Size: 8 MB
  • Pro Tip: Keep your face centered and leave some breathing room around your shoulders. Avoid clutter, fine text, or busy patterns because they vanish entirely when scaled down to a tiny mobile thumbnail.
• Background Banner: 1584 × 396 pixels
  • Aspect Ratio: 4:1
  • Max File Size: 8 MB
  • Pro Tip: Your profile picture overlaps the bottom-left corner of the banner on desktop. Keep your branding, text, and key visual elements anchored toward the center or right side to prevent them from being obscured.

2. Feed Post Image Sizes

When sharing single-image updates, your choice of dimensions dictates how much screen real estate you command in the feed. Since “stopping the scroll” is the ultimate objective, picking the right format is critical.

| Post Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square | 1080 × 1080 px | 1:1 | Infographics, quotes, versatile branding |
| Portrait | 1080 × 1350 px | 4:5 | High-engagement mobile content, tall charts |
| Landscape | 1200 × 627 px | 1.91:1 | Link shares, broad announcements |

• The Portrait Advantage: If maximum engagement is your goal, 1080 × 1350 pixels (4:5) is your best friend. Because it takes up the maximum vertical space allowed on mobile feeds, viewers spend more time looking at your post.
• The Square Safe Bet: 1080 × 1080 pixels is clean, predictable, and renders flawlessly on both desktop and mobile without unexpected cropping.
• The Link Preview Trap: If you share an external article or blog link, LinkedIn automatically pulls the preview image. Design your destination web pages with 1200 × 627 pixel Open Graph (og:image) tags so your link posts don’t look distorted or letterboxed.

3. Carousels & Document Posts

LinkedIn documents (uploaded as PDFs that users can click through like a slide deck) consistently drive some of the highest engagement rates on the platform.

• Slide Dimensions: 1080 × 1080 pixels (Square, 1:1) or 1080 × 1350 pixels (Portrait, 4:5)
• Max File Size: 100 MB (up to 300 pages, though 5–10 slides is the sweet spot for engagement)
• Pro Tip: Always upload your carousels as PDFs rather than PowerPoint files to prevent layout shifts and formatting bugs. Square and portrait formats fill mobile screens vastly better than old-school widescreen landscape slides.

4. Company Page Assets

Building a corporate or brand presence requires adhering to a slightly different set of dimensions:

• Company Logo: 300 × 300 pixels (displayed square with subtly rounded corners)
• Company Cover Photo: 1128 × 191 pixels (Wide landscape banner)
• Life Tab Hero Image: 1128 × 376 pixels

Quick Rules for Formatting Success

1. Mind Your File Formats: Stick to PNG for graphics, charts, and images containing text (it prevents compression artifacts around text edges) and JPEG for standard photography.
2. Watch the File Sizes: Keep single images under 5 MB to ensure they load instantaneously.
3. Design for Mobile First: Since the vast majority of your audience will view your content on a smartphone, keep your text large (at least 24px equivalent) and centered safely away from the absolute margins.

By tailoring your visuals to these exact dimensions, you ensure that LinkedIn’s compression algorithm works for you rather than against you—giving your professional content the polished look it deserves.
